Sleep Sabotages Gym Time!

Unfortunately, the disastrous impact spreads beyond diet and into your workouts. No matter what your fitness goals are, having some muscle on your body is important. Muscle is the enemy of fat—it helps you burn fat and stay young. But sleep (or lack thereof) is the enemy of muscle. Scientists from Brazil found that sleep debt decreases protein synthesis (your body’s ability to make muscle), causes muscle loss, and can lead to a higher incidence of injuries.

Just as important, lack of sleep makes it harder for your body to recover from exercise by slowing down the production of growth hormone—your natural source of anti-aging and fat burning that also facilitates recovery. This happens in two different ways:

1. Poor sleep means less slow wave sleep, which is when the most growth hormone is released.

2. As previously mentioned, a poor night of rest increases the stress hormone cortisol, which slows down the production of growth hormone. That means that the already reduced production of growth hormone due to lack of slow wave sleep is further reduced by more cortisol in your system. It’s a vicious
cycle.

If you're someone who doesn't particularly enjoy exercise, not prioritizing sleep is like getting a physical exam with your father-in- law as the investigating physician: It will make something you don’t particularly enjoy almost unbearable. When you’re suffering from sleep debt, everything you do feels more challenging, specifically your workouts.
