Alcohol and Performance

Alcohol and Performance: What You Need to Know

Alcohol is deeply embedded in our culture, but for anyone recovering from injury or working on rehab, it’s crucial to understand how much alcohol can impact healing, recovery, and overall progress. Whether you’re training for an event or trying to get back to full health, cutting down or cutting out alcohol can be one of the most effective things you can do to support your body’s recovery.

Why Alcohol and Performance Don’t Mix — Especially When You’re Injured

Alcohol doesn’t just affect your workout; it interferes with the body’s natural healing processes that are essential during rehab. Even moderate drinking can reduce muscle protein synthesis by up to 37%, delaying tissue repair. Alcohol also raises inflammation and oxidative stress, which can worsen pain and slow down recovery.

Alcohol impairs hydration and nutrient absorption too, limiting your body’s ability to rebuild muscle, ligaments, and tendons. Strength, endurance, and reaction times can drop by 10–30% when alcohol is consumed, making progress slower and rehab more difficult.

Additionally, alcohol can disrupt sleep, and interrupted or poor-quality sleep leads to reduced recovery, impaired cognitive function, mood disturbances, and a higher risk of injury. Please see our separate blog post on sleep and sleep hygiene if you are keen to know more about the effects of poor sleep on recovery and performance.

What Happens When You Cut Back — or Cut it Out

Taking a break from alcohol during rehab can lead to faster and more effective recovery. As Andy Ramage, founder of One Year No Beer, says: try going alcohol-free for just 30 days — that’s when many people first notice real improvements in energy, pain levels, and healing.

Better Sleep = Better Healing


Alcohol fragments sleep and reduces deep restorative stages. Removing alcohol improves sleep quality, helping your body produce growth hormone that supports tissue repair and pain regulation.

Reduced Inflammation and Pain


Less alcohol means lower systemic inflammation. This supports reduced pain and swelling in injured tissues, helping you get more out of your physio and exercise rehab.

Improved Hydration and Nutrition


Alcohol is dehydrating and impairs absorption of key nutrients like B-vitamins and magnesium, vital for muscle and nerve function. Staying hydrated and nourished optimises your body’s ability to recover.

Stronger, Faster Progress in Rehab


Without alcohol impairing muscle protein synthesis and cognitive focus, you’ll likely notice better strength gains, quicker reaction times, and improved neuromuscular control — all key for regaining function and preventing reinjury.

The Bottom Line

Alcohol can seriously undermine your rehab progress by disrupting sleep, slowing healing, increasing inflammation, and reducing performance. If you’re serious about recovery, even a short break can make a big difference.

Try going alcohol-free for 30 days during your rehab and see how your energy, pain, and progress improve. It’s not about quitting forever — it’s about giving your body the best chance to heal, adapt, and get you back to what you love doing.
