Since consuming alcohol is such an accepted (and sometimes even encouraged!) habit, it’s no surprise that there are prevalent myths and misconceptions about the health of this substance.
Here are some common alcohol myths and share some science-backed truths to consider—before you decide to order that next cocktail or beer
Myth #1 Red wines have heart health benefits.
The reasoning behind this idea is that red wine contains an antioxidant compound known as flavonoids. Flavonoids are cardioprotective, but you’d have to drink copious of wine to get any benefit. Which in turn you’ve counteracted any health-related benefit by exposing yourself to the damaging effects of alcohol.
If you want to enjoy the heart-boosting benefits of flavonoids, opt for fruits and vegetables—such as onions, kale, grapes, tea, peaches, tomatoes, and broccoli
Myth #2: Alcohol helps you sleep.
It’s easy to think that alcohol can help you fall asleep faster. That’s because alcohol is a nervous system depressant, so it may be easier to fall asleep. But during the night, as you metabolize the alcohol and its effects wear off, it definitively disrupts your sleep quality.
While alcohol is indeed classified as a depressant, it can also have stimulating effects depending on the concentration in your blood. Alcohol affects both excitatory and inhibitory neurotransmitters, so when it starts to leave your system during the night, it can increase brain activity (acting as a stimulant), causing you to wake up.
Myth #3 Alcohol relieves stress and anxiety
Having a drink after a rough day is a common habit. Although people turn to alcohol to reduce anxiety, distract their minds, and boost their moods, self medicate. It's important to remember that alcohol is ultimately a depressant.
Just as alcohol may lull you into sleep only to disrupt it in the long run, the initial effects can trick your brain into thinking it’s relaxing—but only at first.
Alcohol actually increases stress.
With your first drink, alcohol floods your brain with dopamine, giving you a temporary stress-relieving boost. Unfortunately that pleasure quickly can quickly evolve into feelings of nervousness and anxiety. This can also lead to a higher heart rate and lower heart rate variability (both symptoms of stress on your body) during the withdrawal period. This is known as an “anxiety rebound,” and it may lead you to consume more alcohol to alleviate your stress, unaware that drinking actually intensifies it. It is a very vicious cycle!
Myth #4 Alcohol will not affect my weight loss or physical performance
If you’re working toward a fat loss, performance or body composition goal, alcohol can seriously offset your progress. Alcohol impairs your physical performance by impairing muscle recovery, slowing down reaction times, and disrupting coordination. It also dehydrates the body, reduces endurance, and interferes with energy metabolism, all of which can negatively impact physical performance and health and well being
The research is clear. Alcohol does significantly affect your health. In general, for brain health, I recommend people drink a maximum of one serving of alcohol once or twice a month. That means one serving equals 350 mls of beer or 150mls of wine. Yes, I know that is not a lot.
Regardless of the guidelines, drinking can be problematic if it results in negative feelings, choices, or outcomes.
