Wearing no clothes could lead to cooler skin temperatures that put ZZZs within reach
Many people believe they were born with the only pajamas needed for a good night’s sleep, but here’s the naked truth: No research directly confirms that sleeping in the buff leads to better slumber.
There is, however, some validity behind the idea of sleeping naked — namely regarding how a cooler skin temperature improves sleep quality.
So, should you consider stripping down at bedtime before sliding under the sheets? Let’s look at the potential benefits (and risks) with behavioral sleep disorders specialist Michelle Drerup, PsyD, DBSM.
Is sleeping naked better?
There are some possible perks to nude sleeping … so, maybe? Here are a few reasons why you might want to slip off your clothes before slipping off to sleep.
Falling asleep faster
Your body naturally works to lower its thermostat to doze off at night through its circadian rhythm, which regulates your sleep/wake cycle. The faster you cool off, the faster you typically catch some ZZZs, says Dr. Drerup.
That’s also one of the reasons why sleep experts recommended that you keep your bedroom temperature between 60 degrees Fahrenheit and 67 degrees Fahrenheit (15.5 degrees Celsius to 19.44 degrees Celsius) for optimal snoozing.
Improved sleep quality
Ever toss and turn in bed because you’re too hot? Sleeping naked certainly removes any possibility of pajama-induced overheating interfering with a good night’s rest. It’s the absolute final move in shedding layers to stay cool.
“There’s no question that cooler is better than warmer for overall sleeping,” says Dr. Drerup.
And getting enough rest is key to … well, just about everything in day-to-day life. Waking up refreshed can help you manage stress more effectively, improve focus, boost performance and make you a more pleasant person.
For women: reduced risk of yeast infections
Tight-fitting underwear can trap heat and moisture between your legs. What makes a yeast infection thrive? Yep — heat and moisture.
Sleeping naked (or even in loose-fitting cotton bottoms) allows for some air circulation around your vagina. Keeping the area cooler and drier may help reduce your chances of getting a yeast infection, too.
For men: potential fertility boost
Heat isn’t a friend of male fertility. Regular exposure to higher temperatures for your testicles can cause sperm counts to drop. Wearing underwear that keeps things packed tight doesn’t exactly offer a cooling effect.
Studies show that men who wear boxers have a higher sperm count than their buddies in briefs. So if loose-fitting boxes help that much, imagine what 8 hours of no clothing might do.
Reasons to keep your PJs on
Sleepwalkers may want to give the idea some extra thought to going au natural to avoid any potential awkward encounters, notes Dr. Drerup.
And if you’re not a fan of doing laundry, consider this: Your washing schedule for bedding may need to increase with more skin-to-sheet contact. (Gross fact: The skin cells you shed in a day can feed 1 million dust mites. You don’t want to turn your bed into their buffet.)
Can you be cool and clothed?
Going to bed “nearly” naked while wearing lightweight and loose-fitting garments can bring you similar quality sleep results as taking everything off. “Tank tops and boxer-style briefs don’t possess a ton of warming qualities,” says Dr. Drerup.
And while being cool is desirable for sleep, you also don’t want to be cold. There’s even evidence that wearing socks to bed to warm your tootsies can help you drift off to sleep.
So, which is it: off or on?
Ultimately, what you wear to sleep is a personal choice. “There’s no proven benefit or harm to sleeping naked,” says Dr. Drerup. “Just do what feels right and then rest easy with your decision.”
Why Your Lower Back Pain Is Worse in the Morning (and What To Do About It)
Your sleep position, immobility, mattress and underlying conditions can all cause morning back pain
There’s nothing worse than waking up on the wrong side of the bed. But it can be hard to avoid when you wake with lower back pain in the morning. A back that throbs, aches or sends shooting pain down your legs can quickly set the tone for your day.
Most people experience lower back pain at some point, and more than 20% have chronic lower back discomfort. It’s the second most common reason people in the U.S. visit their primary care provider — behind colds and flu.
Whether you experience lower back pain all day or only in the morning, understanding what’s contributing to the pain may help you fix it. Pain management specialist Tara-Lin Hollins, MD, shares what might be behind your morning back pain and offers tips to help you wake up pain-free.
4 causes of lower back pain in the morning
Back pain and sleep have a complicated relationship. Pain can disrupt your sleep, and poor sleep can make you more likely to have higher pain. Getting to the bottom of your pain may help end the cycle.
Dr. Hollins says several factors can contribute to morning back pain.
1. The wrong sleep position
You spend a third of your life sleeping or resting, so if your spine is out of alignment while you sleep, it can have a significant impact on your body. Your sleep position affects your alignment and may (or may not) support the natural curvature of your spine.
“It’s common to be so tired at bedtime that you fall into bed and sleep however you hit the bed,” Dr. Hollins says. “But you may not be sleeping in the best position for your spine.”
The most beneficial sleep positions for your back are on your:
Side, with your knees partially bent
Back, as long as you don’t have sleep apnea (which worsens when sleeping on your back)
Sleeping on your stomach makes you more likely to twist your neck to the side — a quick way to throw your neck and spine out of alignment.
2. Lying down for hours
When you sit all day at your desk without moving, it can make you stiff. Similarly, when you sleep, you’re not moving much for seven to eight hours. Lying immobile for a long period could cause you to wake up with back or hip pain.
“Our bodies are not supposed to be stagnant for multiple hours,” Dr. Hollins explains. “Stiffness can settle in, and inflammation can build up. Then, when you try to move in the morning, releasing the inflammation can be painful.”
Tricky, right? After all, you want a good night’s sleep, and lying immobile while you doze is often a sign that you got all of your ZZZs. But to avoid lower back pain, Dr. Hollins advises taking some time to stretch before you jump out of bed.
3. An unsupportive mattress or pillow
Your mattress is your main source of back support while you sleep. And your pillow ensures proper neck alignment. A mattress that’s damaged, too soft or sagging can cause your lower abdomen to sink deeper than the rest of the spine, pulling your back out of alignment.
“All too often, people opt for a soft mattress, thinking it will be more comfortable,” Dr. Hollins notes. “You don’t want a hard mattress, but it should feel firm and supportive. You shouldn’t sink into it.”

4. An underlying condition or pregnancy
Some conditions or chronic diseases may put you at higher risk for morning back pain. Chronic conditions that affect both sleep and morning back pain include:
Pregnancy can also bring back pain in the morning due to:
Additional strain on your lower back muscles
Shifting center of gravity
Increased weight
How to stop waking up with lower back pain
Lifestyle changes, like achieving a healthy weight and exercising every day, are always helpful for back pain. But Dr. Hollins also recommends actions related to sleeping that may additionally help reduce or eliminate your morning back pain.
Add supportive pillows
Pillows are a great way to support your back’s alignment. Your typical sleep position should guide the pillows you use:
Back sleepers. Choose a head pillow that supports your neck and lets your head sink in. Place a pillow under your knees to support your spine’s natural curvature.
Side sleepers. For your head, choose a thick pillow that keeps the top portion of your spine straight and parallel to the mattress. Place a small pillow between your knees to help even out your hips.
Stomach sleepers. Don’t use a pillow for your head, or choose a very thin one. Put a thin pillow under your lower abdomen to keep your spine aligned.
“Look for pillows that are specific to your sleep position,” Dr. Hollins advises. “But no matter which position you use, adding pillows strategically around your body can support your spine and reduce morning pain.”
Adjust your sleep position
If you’re used to sleeping in the same position every night, it can be challenging to change it. But small adjustments may help:
Place both arms in the same position if you sleep on your back — instead of flinging one arm over your head — to keep your spine aligned.
Bend your knees when sleeping on your side to help balance your body and reduce any pressure on your lower spine.
Put pillows in front of you if you sleep on your side so you don’t roll onto your stomach.
Sleep on your left side whenever possible to take pressure off your internal organs.
“You want to be as comfortable as possible when you go to sleep,” Dr. Hollins says. “That way, you’ll be more likely to stay in a supportive sleep position.”
Replace your mattress regularly
According to the Sleep Foundation, the general guideline is to replace your mattress every six to eight years. But you may need a new mattress sooner if yours is:
Making noise (if it’s an innerspring mattress)
Noticeably sagging or damaged
Causing muscle or joint stiffness, especially if you don’t have the same stiffness when you sleep at hotels or other homes
When choosing a new mattress, choose a “medium firm” mattress — level 6 out of 10 on the mattress firmness scale. It may reduce your back pain symptoms by nearly half.
Pause before you get up
Most people get out of bed as soon as they wake up, Dr. Hollins points out. But taking a few minutes to prepare your back for transitioning to sitting, standing and walking can help with morning back pain.
Stretch while you’re still in bed. While on your back, bring one knee to your chest. Hold it for three seconds, let it go and then, switch to the other leg.
Warm your muscles. Slide a heating pad under your back to warm your muscles. Use one that’s designated as safe for use in the bed and has an auto shut-off. Keep the sheet or your shirt between the pad and your skin.
Take your time getting up. First, sit on the edge of the bed and let your back adjust. Then, use your legs — not your back — to stand up.
See your healthcare provider if your back pain worsens or occurs most mornings for two or three months. They can check for underlying back issues and may prescribe physical therapy.
“Don’t wait six or eight months to see your provider,” Dr. Hollins urges. “They can provide guidance about the best stretches to do, and your back will thank you.”
You likely know that drinking alcohol too often or to excess isn’t a good idea, health-wise. But when it comes to alcohol and heart health, you may have heard different sides. Is drinking all that bad for your heart? Can a glass of wine help reduce your risk of heart disease — or make it worse?
First things first: If you drink alcohol, you should do so in moderation to avoid alcohol-related heart issues. And you should never intentionally use alcohol to try to reduce your risk of heart disease.
To further explore the relationship between your ticker and your favorite glass of merlot or IPA, we chatted with cardiologist Leslie Cho, MD.
Ways alcohol can impact heart health
Here are some of the effects of alcohol on your heart:
Increased heart rate
One of the most important things your heart does is keep a rhythm. On average, a regular heart rate is about 60 to 100 beats per minute when your body is at rest. But alcohol can lead to your heart rate temporarily jumping up in speed, and if it goes over 100 beats per minute, it can cause a condition called tachycardia. Too many episodes of tachycardia could lead to more serious issues like heart failure or going into irregular rhythms, which can cause heart attack and stroke.
Raises blood pressure
That fourth drink at the bar may feel like it’s relaxing you, but it’s actually affecting your body differently than you might think. Alcohol can affect your blood pressure, causing it to go up temporarily. This is especially true when you engage in binge drinking (that’s defined as four or more drinks within two hours for women and people assigned female at birth, and five or more drinks within two hours for men and people assigned male at birth).
And sure, we’ve all had a night here or there where we’ve had one too many and we know it. But it’s important to make sure those nights of overindulgence are the exception and not the rule. If you’re not sure, make a note to tune into how much you’re having over the course of the next month or so. If it’s more than recommended, try to consciously pace your drinking to help reduce the spike in your blood pressure that excessive alcohol causes.
And if you have a history of high blood pressure, it’s best to avoid alcohol completely or drink only occasionally, and in moderation.
Irregular heartbeat
Whether it’s a glass of red wine with your turkey or toasting champagne for the new year, alcohol definitely becomes more present during the holiday season. And while enjoying celebratory spirits in moderation is alright for most people, it’s important to be aware you can fall victim to holiday heart syndrome if you overdo it. This is when overeating and overindulging in alcohol lead to an irregular heartbeat.
Holiday heart syndrome can happen if you don’t typically drink alcohol, but then have a few at a holiday party or if you binge drink. This can cause you to develop an irregular heartbeat, called atrial fibrillation, which can increase your risk of stroke, heart attack and heart failure.
Prolonged drinking can cause alcoholic cardiomyopathy
The short-term effects of alcohol (headache, nausea, you know the rest) are easy to pinpoint. But there are ways that alcohol affects your body over time that are important to understand. One of the long-term effects of alcohol on your heart is alcoholic cardiomyopathy. This is when your heart-pumping function gets weaker and your heart gets larger due to changes from heavy alcohol use over a long period of time.
OK, don’t panic. If you’re an occasional drinker, there’s no cause for worry. But it may be worthwhile learning about what counts as binge drinking and whether or not you may be drinking too much and don’t even know it.
Is some level of alcohol safe or beneficial?
It’s true, red wine is a better choice than hard liquor. But can a trip to the wine bar boost your heart health?
You should never consider wine or any other alcohol as a way to lower your heart disease risk. And, in fact, the study also showed that drinking one or fewer drinks per day was related to the lowest likelihood of dying from a stroke. However, Dr. Cho points out that more recent data shows that there may be no amount of alcohol that is truly safe. “The myth that wine is beneficial for heart health is no longer true,” she states.
“It’s not a good idea to start drinking alcohol in an effort to lower your risk of heart disease,” Dr. Cho continues. “It’s better not to drink any alcohol at all.”
It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have.
Age
Let’s face it, a hangover in your mid-40s doesn’t feel the same as one in your early 20s. This is because your age plays a factor in how well you tolerate alcohol. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes.
“As we get older, our ability to clear alcohol definitely decreases and our sensitivity to alcohol probably increases,” she explains. “Also as we get older, we end up having more diseases, so we could be on medicines that can interfere with the way our bodies metabolize alcohol.”
Other medical conditions
In many ways, your medical history (and present) can tell you a lot about your future with alcohol. That means, if you’re living with other medical conditions and/or taking certain medications, this will all have an impact on how alcohol affects you.
“Certain health conditions can make drinking alcohol more dangerous,” Dr. Cho says.
For example, some people who are on cholesterol-lowering medicines may experience muscle aches when they drink alcohol. Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance. So, it’s important to think about your overall health and talk to a healthcare provider about your personal risk factors.
“Alcohol is made out of sugar,” Dr. Cho points out. “So, if you’re predisposed to diabetes or if high triglycerides are one of your issues, it’s not a good idea to drink alcohol.”
Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different. Talk to your healthcare provider about how alcohol might interact with your prescription medicines.
The last thing you want is for that casual drink after work or glass of wine at dinner to negatively impact your heart health. There’s a way to have a healthy, balanced relationship with alcohol that lets you enjoy a drink occasionally and celebrate with friends and family. But your heart is an important organ that should also be cared for, so be sure to drink in moderation, learn about binge drinking and know what your body can (and can’t) tolerate before opening that tab.FACEBOOKTWITTERLINKEDINPINTERESTEmailalcoholalcohol and healthalcoholic beveragesbinge drinkingheart health

As a cardiologist, I am asked almost every day if ‘Alcohol is good or bad for your health?’.
Let’s find out.
Alcohol Is A Toxin.
There is no getting away from the fact that, at its most basic chemical foundation, alcohol is a toxin.
Globally, alcohol is responsible for 3 million deaths per year; in the United States, it is the third leading cause of preventable death¹².
Alcohol is a factor in³:
30% of suicides
40% of fatal burn injuries
50% of fatal drownings
50% of homicides
65% of fatal falls
29% of fatal road traffic accidents
Alcohol is a factor in 1 in 5 emergency department presentations⁴.
No pun intended, but these statistics make for some sober reading.
‘Red Wine Is Good For Your Heart.’
Now come on.
Did you really think that was true?
I have heard this phrase over and over again in my clinical practice.
High levels of exercise are good for your heart, but oddly enough, most people seem to be far less enthusiastic about this approach than regular alcohol consumption.
Let’s see what the data says.
Up until very recently, it was believed that drinking 1-2 drinks per day was actually protective when it came to dying prematurely⁵.
This data was based on observational studies that cannot fully control for all confounders and can therefore not infer causality.
When you examine the people who drink only 1 to 2 drinks per day, you consistently find that they are much less likely to smoke, be overweight or engage in any other risky health behaviours.
So in truth, it probably wasn’t the alcohol that was driving the effect.
More recent studies have attempted to control for this variable more carefully, and the relationship is clear.
The more you drink.
The higher the risk.
Take coronary artery disease. Higher alcohol intake equates to a higher risk.
The same applies to high blood pressure⁶.
The same applies to stroke⁷.
The list goes on⁸:
Atrial fibrillation – Higher risk.
Sudden death – Higher risk.
Heart failure – Higher risk.
Liver, Breast, Colorectal, Oropharyngeal Cancer – Higher Risk⁹.
You get the point.
With all this information to hand, why is it then that I and billions of others continue to drink alcohol?…

Alcohol can affect your blood pressure, causing it to go up temporarily. This is especially true when you engage in binge drinking (that’s defined as four or more drinks within two hours for women and people assigned female at birth, and five or more drinks within two hours for men and people assigned male at birth).

The short-term effects of alcohol (headache, nausea, you know the rest) are easy to pinpoint. But there are ways that alcohol affects your body over time that are important to understand. One of the long-term effects of alcohol on your heart is alcoholic cardiomyopathy. This is when your heart-pumping function gets weaker and your heart gets larger due to changes from heavy alcohol use over a long period of time.
OK, don’t panic. If you’re an occasional drinker, there’s no cause for worry. But it may be worthwhile learning about what counts as binge drinking and whether or not you may be drinking too much and don’t even know it.
Is some level of alcohol safe or beneficial?
It’s true, red wine is a better choice than hard liquor. But can a trip to the wine bar boost your heart health?
You should never consider wine or any other alcohol as a way to lower your heart disease risk. And, in fact, the study also showed that drinking one or fewer drinks per day was related to the lowest likelihood of dying from a stroke. However, Dr. Cho points out that more recent data shows that there may be no amount of alcohol that is truly safe. “The myth that wine is beneficial for heart health is no longer true,” she states.
“It’s not a good idea to start drinking alcohol in an effort to lower your risk of heart disease,” Dr. Cho continues. “It’s better not to drink any alcohol at all.”
It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have.
Age
Let’s face it, a hangover in your mid-40s doesn’t feel the same as one in your early 20s. This is because your age plays a factor in how well you tolerate alcohol. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes.
“As we get older, our ability to clear alcohol definitely decreases and our sensitivity to alcohol probably increases,” she explains. “Also as we get older, we end up having more diseases, so we could be on medicines that can interfere with the way our bodies metabolize alcohol.”
Other medical conditions
In many ways, your medical history (and present) can tell you a lot about your future with alcohol. That means, if you’re living with other medical conditions and/or taking certain medications, this will all have an impact on how alcohol affects you.
“Certain health conditions can make drinking alcohol more dangerous,” Dr. Cho says.
For example, some people who are on cholesterol-lowering medicines may experience muscle aches when they drink alcohol. Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance. So, it’s important to think about your overall health and talk to a healthcare provider about your personal risk factors.
“Alcohol is made out of sugar,” Dr. Cho points out. “So, if you’re predisposed to diabetes or if high triglycerides are one of your issues, it’s not a good idea to drink alcohol.”
Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different. Talk to your healthcare provider about how alcohol might interact with your prescription medicines.
The last thing you want is for that casual drink after work or glass of wine at dinner to negatively impact your heart health. There’s a way to have a healthy, balanced relationship with alcohol that lets you enjoy a drink occasionally and celebrate with friends and family. But your heart is an important organ that should also be cared for, so be sure to drink in moderation, learn about binge drinking and know what your body can (and can’t) tolerate before opening that tab.FACEBOOKTWITTERLINKEDINPINTERESTEmailalcoholalcohol and healthalcoholic beveragesbinge drinkingheart health
Alcohol is a Group-1 carcinogen—but one that happens to be woven into our daily lives and often viewed as a go-to way to cope with stress or disappointment. Here are 5 ways to change that mindset, writes
Alcohol is a Group 1 carcinogen—putting it in the same category as asbestos, radiation, and tobacco.
Alcohol is woven into our daily lives and often viewed as a go-to way to cope with stress and disappointment.
Less than half of Americans are aware that drinking alcohol increases their risk of cancer.
There are healthier, more sustainable ways to manage stress.
“I need a stiff drink!” “Let’s drown our sorrows.” “I just need to unwind with a glass of wine.”
Phrases like these are so common, we barely think twice about them. Alcohol has become deeply woven into our daily lives and culture. It’s often seen as a go-to way to cope with stress, disappointment, or just the pressures of everyday life. Got bad news? Feeling overwhelmed? Need to relax? Society has taught us that it’s totally normal—even expected—to pour a big glass of wine, toss back a couple of tequila shots, or order a double whiskey.
In fact, using alcohol to handle stress is often not only accepted but actively encouraged by friends, coworkers, and the media. Movies and TV shows constantly show characters doing the same, reinforcing the idea that this is just how we deal with life.
But here’s the truth: alcohol is the one of the most widely used drugs in the world. And the way we’ve normalized it’s use as a coping mechanism deserves a closer look.
The Hidden Cost of Your Evening Glass of Wine
Alcohol is a toxic, psychoactive substance that can lead to dependence. It’s also been officially classified as a Group 1 carcinogen by the International Agency for Research on Cancer—putting it in the same category as asbestos, radiation, and tobacco. Research shows that alcohol contributes to at least seven different types of cancer, including some of the most common, like colon cancer and breast cancer. In fact, earlier this year, former U.S. Surgeon General Vivek H. Murthy issued a public health advisory warning about the clear link between alcohol use and cancer risk.
What’s concerning is that less than half of Americans are aware that drinking alcohol increases their risk of cancer. As a psychiatrist who often discusses alcohol use with patients, this lines up with what I see in practice. Many people simply don’t know that alcohol is a carcinogen. Even more common is the belief that low levels of alcohol—like a glass of wine a day—are actually good for your health, especially for the heart and brain. But that idea is being seriously questioned. In January 2023, the World Health Organization published a statement in The Lancet Public Health making it clear: When it comes to alcohol, there is no safe amount that doesn’t affect your health.
5 Things to Think About Before Reaching for a Drink to Cope With Stress
Alcohol is a known carcinogen—and a cancer diagnosis can deeply affect your mental health. Depression and anxiety are incredibly common among people with cancer. Research shows that up to 1 in 5 cancer patients experience depression, and 1 in 10 struggle with anxiety—regardless of where they are in their treatment or disease process. In fact, according to international diagnostic guidelines, about 35–40% of cancer patients meet the criteria for a psychiatric disorder. These mental health challenges don’t just impact emotional well-being—they can significantly reduce the overall quality of life for persons living with cancer. The global rate of depression among cancer patients is currently estimated at 27%. This is a noticeable increase compared to earlier data, and this trend appears to be on the rise.
That “relaxing” drink may be increasing your anxiety. While alcohol can feel calming in the moment, it’s a short-lived effect. Once the pleasurable effects of alcohol wear off, anxiety can rebound—often worse than before. Over time, this can make stress and mood disorders more difficult to manage.
Regular drinking can sneak up on you—building tolerance, dependence, and emotional numbness. What starts as the occasional glass of wine to unwind can quickly become a nightly ritual. Your body builds tolerance, meaning you need more to feel the same effects. Emotionally, alcohol can dull not just stress but joy, connection, and motivation—leaving you feeling more flat than relaxed.
Alcohol disrupts sleep, even if it helps you fall asleep. Many people use alcohol to wind down at night, but it actually interferes with sleep architecture. It may help you fall asleep faster, but it reduces the quality of your rest—leading to more fatigue, irritability, and difficulty coping with stress the next day.
There are healthier, more sustainable ways to manage stress. Whether it’s exercise, deep breathing, journaling, therapy, or connecting with others, there are countless tools for managing stress that don’t carry the risks alcohol does. Exploring these options might not provide the instant hit that a drink does—but they build resilience, not reliance.
Let’s start with some simple facts. Alcohol is a toxin. Alcohol is a factor in1: 30% of suicides 40% of fatal burn injuries 50% of fatal drownings 50% of homicides 65% of fatal falls 29% of fatal road traffic accidents Globally, alcohol is responsible for 3 million deaths per year; in the United States, it is the third leading cause of preventable death23. It is hard to see the upside when you see these figures. So let’s go a little deeper. First off, I drink alcohol. Not a lot. But I do drink. So any comments made here are not some puritanical position on alcohol but reflections on the data that exist in the literature. Multiple studies have demonstrated that excess alcohol consumption, usually defined as consuming greater than 2 to 4 drinks per day, is associated with worse outcomes and a greater likelihood of dying when compared to someone who drinks less than 2 to 4 drinks per day4. Alcohol Dosing and Total Mortality in Men and Women: An Updated Meta-analysis of 34 Prospective Studies. Arch Intern Med.2006
In the study shown above, females start to accrue an increased risk at greater than two drinks per day on average and males at greater than four drinks per day.
These findings shouldn’t come as a surprise to anyone.
Surprisingly, on average, individuals who consume less than two drinks per day appear to have better outcomes than those who do not drink at all. This is where things start to get a little counterintuitive, and the story of alcohol being beneficial for you starts to appear.
This relationship is known as a ‘U’ shaped curve where those in the middle have the best outcomes, and those on the edges have worse outcomes. A kind of ‘Goldilocks’ relationship; “Not too hot. Not too cold. Just right.”
How might we explain this?
Enter the darling of the 1990s, Resveratrol. This compound in red wine spawned the mantra that red wine was ‘good for your heart’. This was based on research that suggested that it might reduce cholesterol levels, among other things.
But to consume the levels of Resveratrol tested in some of the animal studies that demonstrated benefit, you would have to drink 40 litres of wine…… Per day.
Not exactly a feasible strategy. Even with the best will in the world.
Let’s look at a more plausible explanation.
Data on alcohol consumption and outcomes are almost always based on observational data, not randomised controlled trials. This means that other factors or ‘confounders’ may explain the difference between the groups, not the alcohol consumption alone.
When you look at the trials that suggest a benefit of modest alcohol consumption, you will often find that this group tend to exercise more, smoke less, be in a higher socioeconomic bracket etc. This is referred to as a ‘healthy user bias’ and is likely to explain the difference between the groups.
Most trials try to correct or adjust for these confounders, but in truth, it is very hard to do. A recent publication looked at this problem and attempted to (as much as possible) correct for these ‘healthy user’ bias factors and then compare outcomes between alcohol consumption groups. The results were a little more in line with what we might expect.
Those in the lowest alcohol consumption category had the best lifestyle factors overall. When these healthy factors were corrected for, any benefit seen with modest alcohol consumption disappeared. What remained was a linear relationship between alcohol consumption and coronary artery disease5. Much more what you might expect.
Association of Habitual Alcohol Intake With Risk of Cardiovascular Disease. JAMA Netw Open. 2022
Research like this and other studies is where the more recent media reports of ‘any’ alcohol being bad for you have come.
So, alcohol is a toxin. But, as Paracelsus notes:
“The dose makes the poison.”
Even water consumed to excess can be lethal.
We know that excess alcohol consumption is harmful. But I don’t think there was any great uncertainty around that point.
The key takeaway is that modest alcohol consumption is unlikely to be ‘beneficial’ to you. As much as you loved the idea that red wine was good for your heart, we can say with reasonable confidence that this is not the case.
The real question we need to answer is whether consuming modest amounts of alcohol is considerably worse for you when it comes to heart disease and death from any cause.
Based on the literature to date, it seems that the incremental risk for modest amounts of weekly alcohol consumption is likely to be small. But that doesn’t mean there are no downsides.
Sleep
One of the main reasons I significantly reduced my alcohol consumption was its effect on my sleep. If I drink more than one drink, I find that the quality of my sleep gets worse. I am much more likely to wake in the middle of the night and feel the effects the following day. But that’s just my personal experience.
Although alcohol is likely to make you fall asleep faster, it impacts your sleep quality6. Additionally, alcohol also reduces the percentage of REM sleep a person gets overnight7.
A workaround for me is to consume any alcohol during the daytime, so my sleep is unlikely to be affected, and if I am going to have a drink, I make sure it is worthwhile. I.e. I am with friends, or it is a high-quality drink. No more drinks on airplanes for me. Mainly because you lose about 30% of your sense of smell and taste in a pressurised cabin and therefore you are less likely to enjoy your drink8. Why do you think they serve you tomato juice and the fact that you think it’s tolerable?!
Humans have been consuming alcohol as far back as the ancient Egyptians, and some evidence suggests the Chinese were consuming alcohol as far back as 7000 B.C. So I don’t see alcohol disappearing any time soon.
The question we all need to ask is:
How much are we realistically drinking on a daily or weekly basis &
Is it likely to be doing us harm?
Only you can answer that question.
The only way to be certain you are doing no harm is to eliminate alcohol entirely. But life is full of risks, some of which we can control, some we cannot.
And some risks are worth taking.
Want to eliminate all road traffic accidents worldwide?
Simple.
Ban cars.
But at what cost?
The risks of driving are a risk most of us are willing to take.
