Brownout vs. blackout from drinking @ClevelandClinic #encephalopathy

Excess alcohol and substance use can cause temporary and permanent memory loss

What are blackouts and brownouts?

Blackouts involve complete memory loss caused by your brain’s inability to record new memories for a period of time due to the effects of excessive alcohol, substance misuse or some other condition.

But sometimes, auditory or visual cues can help a person piece together memories of what happened during a blackout. These cues could come in the form of texts, pictures or conversations with people who were present while you were blacked out. The medical term for blackouts is called transient loss of consciousness (TLOC).

The difference between a brownout and a blackout is that brownouts involve partial memory loss. With a brownout, you may be able to remember certain details from the period of time you were affected, but other portions of time can’t be recalled.

“The hippocampus is a part of your brain that takes our experiences and the awareness of all our senses and processes those into memories,” explains Dr. Streem. “It’s sensitive, and it’s the same part of the brain that deteriorates in people with Alzheimer’s disease.”

Excessive alcohol use isn’t the only thing that can cause blackouts or brownouts. Substance misuse on its own or with alcohol can increase your likelihood of experiencing a blackout. Hypnotics or sedatives and benzodiazepines like flunitrazepam (also known as Rohypnol or roofies) can also lead to blackouts or brownouts.

There are other medical conditions that cause blackouts or brownouts, too, including:

“Anything that causes damage to the brain, whether temporary or permanent, can cause memory loss if the damage is in the right spot,” states Dr. Streem.

Is a blackout the same as passing out?

Blackouts are not the same as passing out. When you pass out or faint, you experience a temporary loss of consciousness.

“When you’re passed out, you’re not awake. A blackout happens to someone who’s still conscious but they’re not coding any new memories,” explains Dr. Streem. “A person who has a blackout is still awake and they have some ability to think, but other parts of their brain may not be working well enough. Often, this is because of intoxication.”

Understanding these definitions and the difference between blackouts and passing out is incredibly important, as it may be difficult for other people to recognize someone is having a blackout because of their seemingly aware state.

How much alcohol can cause a blackout?

How much alcohol or substance use is needed to cause a blackout varies based on a person’s height, weight, sensitivity and assigned sex at birth.

“We know females absorb more alcohol in their bloodstream than males,” says Dr. Streem. “But for most people, it’s going to involve more than the legal blood alcohol limit. In almost all states in the U.S., the blood alcohol limit for driving is .08. Blackouts usually appear at blood alcohol levels that are twice the legal limit or higher.”

Studies have shown that young adults under the age of 25 are particularly vulnerable to experiencing blackouts. Additionally, blackouts may occur at far lower thresholds among younger populations. That’s largely because the parts of your brain responsible for decision-making aren’t fully matured until around age 25. Despite this, intentional binge drinking has been a common practice among young adults.

Regardless of age, recent studies show more frequent blackout experiences are related to an increase in memory lapse and cognitive difficulties even after alcohol misuse is corrected. This means that even after a blackout occurs, you can continue to experience memory loss and other difficulties recalling memories.

Blackout effects on your body

If you’re experiencing a blackout or brownout, you’re at higher risk for falling, injury and unwanted or unsafe sexual experiences. A person who is blacked out may also throw up while sleeping, which could lead to an increased risk of choking or suffocating.

It can be hard to determine when you’re going to have a blackout or brownout. But some signs it may be happening to you in the moment include:

  • Difficulty standing.
  • Nausea.
  • Lightheadedness.
  • Loss of vision or shrinking of your field of view.

Other signs of substance-related blackouts, specifically blackouts caused by sedatives, hypnotics or benzodiazepines, include:

  • Loss of bowel or bladder control.
  • Difficulty breathing.
  • Feeling drunk when you haven’t consumed alcohol or consumed less than your usual amount.
  • Sudden body temperature changes.
  • Sudden increase in dizziness, disorientation, loss of vision or difficulty speaking.

“Hypnotic drugs are prone to cause this kind of impairment and memory loss,” states Dr. Streem. “Sadly, people sometimes use them to take advantage of other people.”

Strategies for managing blackouts

A blackout ends when your body has absorbed the alcohol you consumed and your brain is able to make memories again. Sleep often helps this process along.

Alcohol is dehydrating by nature, so making sure you’re drinking plenty of water and staying hydrated is important. Being aware of potential signs of intoxication can also be helpful in understanding your limitations.

But what if you end up having a blackout anyway?

“The experience of a blackout can sometimes be an opportunity to learn about our bodies and our brains, and what we can and can’t handle,” says Dr. Streem. “But the most important thing to do when you have a blackout is to try and piece together as best we can what happened and whether we were injured. It also might be necessary to try to assess whether you’ve been taken advantage of in some way.”

If you think you’ve been injured, sexually or physically assaulted, it’s important that you get medical attention immediately and talk to the police about everything you can remember.

Other measures you can take to reduce the likelihood of blackouts and brownouts and increase your own safety include:

  • Drinking with people you trust.
  • Pairing up with a close friend or group of friends and leaving together.
  • Not drinking on an empty stomach.
  • Not taking drinks from other people.
  • Opening containers yourself or watching your drink being poured.
  • Taking your drink with you when leaving a room.
  • Not drinking anything that tastes or smells odd.
  • Asking for help when you start to feel drunk or intoxicated.

“There’s no way to prevent a blackout or brownout from happening other than to stop consuming so much alcohol or other substances that cause them,” says Dr. Streem. “Beyond that, safety and general physical care can be very helpful in making sure this doesn’t happen to you.”

Can stripping down for bedtime help you catch some ZZZs? @ClevelandClinic

Cleveland Clinic

Is It Healthy To Sleep Naked?

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.”

When you’re pregnant, it’s important to eat a healthy diet that provides the nutrients you need. That helps keep you feeling your best and promotes healthy fetal development. But pregnancy also puts you at higher risk for foodborne illness. Some foods and drinks can increase your risk for pregnancy complications. Avoid high-mercury fish and processed meat, and go easy on salt and caffeine.

Dr.Paddy Barrett – The Truth About Alcohol and Health

Why the idea that “a little red wine is good for your heart” doesn’t hold up anymore.

I used to drink.

A lot more than I should have.

And while I had some seriously good times when I was drinking, it came at a huge cost.

Brutal hangovers. Terrible sleep. Wrecked weekends.

Even a broken back.

(But that’s a story for another day.)

I still drink.

But just very little these days.

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?…

Why Experts Say To Avoid Beer Tanning @ClevelandClinic

You’re putting your skin at risk of sunburn and even skin cancer when you pour on the beer

There’s a good chance you think a golden tan makes you look more youthful, healthier and more attractive. And while there are many ways to achieve a faux bronzed glow — think bronzers and sunless tanners — you might be tempted to try an unsafe way to get a suntan.

One of those dangerous trends is beer tanning (yes, you read that right!). The idea is that slathering your skin with beer will help you achieve a darker, richer color.

You can thank social media for spreading the concept of beer tanning. But just because TikTok or Instagram influencers are touting the results of something, doesn’t mean it’s not without its risks (Exhibit A: nasal tanning sprays).

Dermatologist Shilpi Khetarpal, MD, explains how beer tanning can harm your skin and why it’s so important to protect your skin.

What is beer tanning?

Instead of using sunscreen, people use the alcoholic beverage like a tanning lotion. The thought process is that hops — one of the main ingredients in beer — increase your skin’s melatonin.

But Dr. Khetarpal wants to be very clear: There’s no scientific evidence to support this theory. And you’re leaving your skin in a vulnerable state with no SPF protection at all.

“There are many issues with this idea of beer tanning,” she continues. “The first is that if you’re not applying sunscreen, the skin is not protected. It can also increase the chance of getting a sunburn and lead to an increased risk of skin cancer.”

The dangers of beer tanning

Just like tanning beds and using tanning oil, beer tanning is NOT good for you or your skin.

Beer tanning essentially leaves your skin unprotected. Exposure to the sun’s harmful ultraviolet (UV) rays can lead to:

And what might be most concerning is who is following this unsafe idea.

“The age groups that are following these trends are 15- to 34-year-olds — and it’s also the same age group that has a disproportionately high incidence of skin cancer and that’s on the rise,” says Dr. Khetarpal. “We’re going to see that number go up as this population ages.”

The facts on skin cancer — the most commonly diagnosed cancer in the U.S. — paint a scary picture. Here are just some of the alarming stats:

“We get most of our sun exposure during childhood, so it’s important to wear sunscreen every day even if you’re not outdoors,” stresses Dr. Khetarpal. “The increase in UV exposure and tanning beds is why there is an increase in skin cancer that we’re seeing today.”

How to keep your skin protected

Dr. Khetarpal can’t over-emphasize the importance of protecting your skin when you’re outside. So, what should you do? Here are her tips:

  • Wear sunscreen. Opt for a broad-spectrum sunscreen that’s UVA/UVB SPF 30 or higher.
  • Wear UPF clothing. UPF stands for “ultraviolet protection factor,” and certain clothing is made with UPF fabric.
  • Wear a hat and sunglasses. These items can help protect your face, the back of your neck and your eyes.
  • Seek out shady areas when you can. Not only can this help protect your skin, but getting a break from the hot sun can also reduce your chance of dehydration and heat stroke. Consider an umbrella when you’re at the beach.

“Protect your skin by wearing an SPF 30 or higher daily, regardless of the weather and reapply every 2 hours when outdoors,” reiterates Dr. Khetarpal. “You can also look for UPF-protected clothing and seek shade during peak sun hours, which are typically 10 a.m. to 2 p.m.”

Bottom line?

Sure, we get it — our society is somewhat obsessed with suntans and having a bronzed look. But as with most viral trends, beer tanning can do more harm than good. Ask yourself: Is having a tan worth the potential for skin cancer down the road?

And if you’re like us and Dr. Khetarpal, not only is it not worth the risk of sunburn, heat exhaustion and skin cancer, but it’s also not worth the mess it creates.

“Besides everything we know about ultraviolet exposure and putting yourself outside without sunscreen, why would you want to put something sticky and messy all over your body?” asks Dr. Khetarpal.
