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.

A group of adults are taking a fitness class together at the gym. They are working out on exercise mats and are holding a high plank.
A physical therapist answers your questions
If you suffer from back pain, you’ve probably heard that strengthening your core can bring you some relief. But is this always true? And if so, how do you do it? We spoke with Cleveland Clinic physical therapist Patti Mariano, DPT, to find out.
Q: What is your core?
When most people think about the core of the body they think of the abdominal or six-pack area just below the ribs. While the abdominal muscles are an important part of the core, we consider other areas important, too.
Your core includes:
Front abdominal muscles — the rectus abdominis
Muscles along the side of your body — the internal and external obliques
A deep muscle that wraps around the front — the transverse abdominis
Muscles in your back that are located between your spine bones and run along your spine — the erector spinae and multifidi
Your core also includes the diaphragm and muscles of the pelvic floor. I also consider the gluteal muscles as core muscles.
Q: What is the relationship between core strength and back pain?
Theoretically, if your muscles around the low back are weak, your body will rely more on passive structures, including ligaments — the tissue that connects bone to bone — as well as the spinal bones or discs, which lie between the spinal bones, for stability, which can cause pain.
But some studies have shown that specific core exercises are not any more beneficial than general exercise for low back pain. What we know is that exercise in general can help, and focusing on core muscles may provide some additional benefit.
Q: What are some exercises for the core that can help with back pain?
Here are my top five:
Side plank — Sit on the floor with your right hand below your right shoulder and feet stacked. Lift your body, keeping your legs long, abdominals engaged and feet stacked. Hold. Repeat on the other side. You can modify this pose by dropping your bottom knee to the floor for extra support.
Plank — Kneel on all fours. Pull in your abdomen and step your feet behind you until your legs are straight. Keep your hands directly under your shoulders and your neck straight. Hold your abdomen and legs tight and avoid letting your lower back sag. Hold and breathe for 30 seconds. You can modify this pose by lowering your knees.
Bird dog — Kneel on all fours. Reach one arm out in front of you, draw in your abdomen, and extend the opposite leg long behind you. Repeat on the other side.
Scissors — Lie on your back with your arms at your sides and legs pointed straight into the air above your hips. Press your lower back into the mat and tighten your abdomen. Lower your right leg until it’s a few inches from the floor. Raise your right leg up and begin lowering your left leg the same way. Continue switching right and left.
Upward dog — Lie face down with head slightly lifted and hands palm-down under your shoulders. Point your toes. Exhale, then press through your hands and the tops of your feet and raise your body and legs up until your arms are straight and your body and legs are off the ground. Keep your neck relaxed and long and thigh muscles tight as you hold and breathe.
For the plank exercises, start by holding them for 15 seconds to 30 seconds. For bird dog and scissors, try three sets of eight or 10 repetitions. For upward dog, do one set of 10 repetitions.
Q: Can you injure your back by trying to strengthen your core?
Any exercise performed incorrectly, whether it is core-strengthening or otherwise, has the potential to cause discomfort.
Twisting exercises or even incorrectly completing the exercises cited above can cause pain in the low back. But it’s highly unlikely that one repetition of an exercise will seriously harm your body, unless it’s an exercise using a very heavy weight.
The best way to keep your body safe is to listen to body cues such as pain during and immediately after an exercise, and the next day after exercising.
Q: When should you talk to a doctor about your back pain?
If any of the following is going on you should consult with your doctor:
Your pain has been going on for longer than a month, despite resting from activities that make it worse.
Your pain is getting worse.
Your pain wakes you from sleep.
Your pain is in your low back but also is going down one or both of your legs.
You notice that one leg is becoming weaker than the other.
Q: Where should you turn if you want help in creating a plan to address back pain?
Physical therapists train as musculoskeletal experts — they are the experts on muscles, bones and human movement. These professionals are the most qualified, aside from an orthopedic doctor, to assess back problems.
Since there are many factors that impact low back pain and many types of low back pain, it is a good idea to visit at least one time with a physical therapist for an evaluation and subsequent plan of care. This will give you an individually tailored plan with exercises that progress safely.
The idea of core strengthening, while beneficial, is just one piece of the low back pain puzzle.
