Beer After Working Out: Good Or Bad Idea?

Drinking beer after a workout is a popular way to celebrate, socialise, and relax. But is it bad for you? The answer is: it's complicated. While a single beer after exercise won't harm you, regular post-workout drinking can negatively impact your health and fitness goals. Alcohol is a diuretic, meaning it increases urine production and can lead to dehydration, especially when combined with fluid loss from sweating during exercise. This can hinder post-workout recovery, as adequate hydration is crucial for muscle repair and growth. Alcohol also impairs protein synthesis, which is necessary for rebuilding torn muscles, leading to increased muscle soreness and reduced muscle mass gains. Additionally, alcohol can disrupt sleep, negatively affect hormone levels, cause nutritional imbalances, and increase the risk of injuries. However, some sources suggest that light, low-ABV beers may have potential benefits as a post-workout drink, providing carbohydrates and electrolytes for recovery.

Beer may be a better post-workout drink than previously thought

It's common to go for a drink at the local bar after a workout with friends, and drinking beer after exercising is so popular that races like 5Ks and marathons often have beer for purchase near the finish line. However, drinking beer after a workout can affect your post-workout recovery. Experts say that the more you drink, and the more regularly you do it, the more your recovery and overall fitness level may be affected.

Dehydration

Drinking beer after a workout can lead to dehydration. Alcohol is a diuretic, which means it makes your body produce more urine, and causes you to urinate more fluids than usual. One study showed that people urinated more than usual after drinking a 4% alcoholic drink post-workout, which may contribute to dehydration. However, another study in the Journal of Applied Physiology found that rehydration after sport is only delayed if you consume alcohol with an ABV that is greater than 4%. So if you do want to drink beer after a workout, choose a low-ABV option.

Inadequate muscle recovery

Exercise causes tiny tears in your muscles that need to be repaired with protein (called muscle protein synthesis). But alcohol can interfere with protein synthesis, leaving your muscles sore and damaged. Alcohol can also suppress the production of protein needed to repair muscle damage after exercise, which can be harmful to athletic performance later on.

Nutritional imbalances

When exercisers refuel with alcohol instead of carbohydrates, protein, and electrolytes, they’re depriving their bodies of the energy sources they need for peak performance and recovery. Alcohol lowers your inhibitions, which may cause you to desire unhealthy foods for your post-workout meal, further setting you off your plan.

Sleep disruption

Drinking alcohol after a workout can disrupt sleep and reduce the secretion of human growth hormone (HGH) necessary for muscle repair and growth, impacting overall recovery.

Weight gain

Most alcoholic beverages are calorie-heavy. Even a light beer can clock in at around 100 calories. So if you’re exercising to help with weight loss, drinking alcohol won't help you. Alcohol is also a source of so-called 'empty calories', providing lots of energy but little nutritional value. Ultimately, this means that the calories you consume from alcohol are more likely to be turned into fat.

Other risks

Drinking beer after a workout can lead to more injuries, as alcohol can affect your balance and coordination. It can also negatively impact pre-existing conditions, and cause negative interactions with medications.

Alcohol affects your body in a number of ways

Secondly, alcohol affects your liver function. Your liver has to prioritise dealing with the toxins produced by alcohol, rather than its usual tasks such as producing glucose or clearing lactic acid. This can disrupt the normal functioning of your body and impact your workout recovery.

Thirdly, alcohol is a depressant, which means it relaxes you but can also affect your balance, coordination and mood. It can also impact your heart rate and, in cases of heavy drinking, can lead to arrhythmias or abnormal heart rhythms. These effects can be particularly dangerous if you exercise while under the influence of alcohol, increasing the risk of injury.

Finally, alcohol can affect your sleep patterns. Even a small amount of alcohol can disrupt your sleep cycle, leading to more disruptions and less restorative sleep. Sleep is crucial for muscle recovery, so alcohol can indirectly hinder your body's ability to repair and rebuild muscle tissue.

Drinking after a workout can impair muscle recovery

Secondly, alcohol consumption can reduce your body's ability to synthesise proteins. Exercise creates small tears in your muscles, and your body uses protein to repair this damage. However, alcohol inhibits the utilisation of protein, leading to increased muscle soreness and reduced muscle mass gains.

Thirdly, alcohol can disrupt sleep, which is essential for muscle recovery. It can negatively impact the duration and quality of sleep, reducing the time spent in important stages of the sleep cycle. Sleep is when your body produces human growth hormone (HGH), which is necessary for muscle repair and growth.

Additionally, drinking alcohol after a workout can lead to higher cortisol levels and lower testosterone levels. Cortisol is a stress hormone that can inhibit protein synthesis, while testosterone is crucial for building muscle bulk and strength.

Finally, alcohol is a source of empty calories, providing energy but little nutritional value. This can hinder weight loss efforts and contribute to fat storage.

While drinking a small amount of low-ABV beer occasionally may not significantly impact muscle recovery, regular or excessive alcohol consumption can impair your body's ability to recover from exercise. Therefore, it is generally recommended to choose non-alcoholic or low-alcohol alternatives and prioritise proper hydration, nutrition, and sleep for optimal muscle recovery.

Alcohol can negatively impact your sleep

Alcohol is known to interfere with your sleep, particularly REM sleep, which is essential for muscle recovery. Research has shown that even a small amount of alcohol can negatively impact your sleep. After drinking, you spend less time in certain important stages of the sleep cycle, resulting in more disruptions and a shorter sleep duration.

Studies have also found that alcohol reduces the secretion of human growth hormone (HGH), which is necessary for muscle repair and growth. When alcohol disrupts sleep, it can reduce the secretion of HGH by up to 70%.

Additionally, getting enough sleep after working out is crucial for strengthening your muscles and preventing exercise-related injuries. Therefore, drinking alcohol after a workout can hinder the recovery process by disrupting your sleep and reducing the production of hormones needed for muscle repair.

If you're serious about fitness and optimising your recovery, it's best to skip the post-workout alcoholic drink and opt for non-alcoholic alternatives or recovery drinks that provide your body with the nutrients it needs to rebuild and repair.

There are alternatives to drinking beer after a workout

Drinking beer after a workout can be detrimental to your health and fitness goals. However, if you're looking for a refreshing drink to unwind with post-exercise, there are plenty of alternatives to beer that won't have as many negative effects on your body.

Non-alcoholic beer is a great option if you want to enjoy the social aspects of drinking without the harmful effects of alcohol. These drinks used to be associated with a lack of taste, but that's no longer the case. There are now many craft breweries creating non-alcoholic beers in a variety of styles. Athletic Brewing, for example, specialises in non-alcoholic beer and sparkling water for athletes.

Mocktails are another excellent choice, often containing fruit juices, sparkling water, and other non-alcoholic ingredients that can provide you with the carbohydrates needed for recovery. If you're heading to a bar, many now offer mocktail menus or can create a drink to suit your tastes.

Recovery drinks are also a great option, providing your body with the protein, carbohydrates, and electrolytes needed to support your body after vigorous exercise. A smoothie with bananas, berries, and milk, or even a glass of chocolate milk, can be a great recovery drink.

If you're looking for something simpler, water is always a good choice to rehydrate after a workout.

So, while the occasional beer after a workout won't do any serious harm, there are plenty of other options that can support your body and fitness goals without the negative side effects of alcohol.
