Why working out after drinking could endanger your health

Returning to the gym after a night of drinking may seem like a good way to bounce back, but experts warn it can be risky. Cardiologist Alexander Rogachev advises against intense workouts while the body is still processing alcohol. Even if someone feels fine, lingering effects can pose serious health threats.

Alcohol disrupts key bodily functions, making exercise unsafe for up to two days after drinking. The vestibular system—responsible for balance—becomes impaired, slowing reaction times. This increases the risk of accidents, particularly in high-intensity or extreme sports.

Dehydration, low blood sugar, and electrolyte imbalances worsen during a hangover. These conditions strain the heart, raising the likelihood of irregular heartbeats and blood pressure spikes. Aerobic exercise under these circumstances puts extra pressure on the myocardium, which can be dangerous.

The body takes time to recover fully. Metabolising one standard drink requires about an hour, but regaining peak physical performance often needs 48 to 72 hours. Factors like body weight, metabolism, and food intake influence recovery time. Until then, light activities such as walking, stretching, or controlled breathing are safer options. Proper sleep, hydration, and nutrition also help stabilise the body.

Resuming exercise too soon after drinking can harm the cardiovascular and nervous systems. The safest approach is waiting until alcohol has fully cleared and the body feels stable. Only then should more demanding physical activity be considered.
