Sleep Necessary for Recovery and Restoration

Sleeping is good for you. How do we know? Well, don’t you always feel better – more energetic, more focused and, generally, are in a more better mood – after a good night’s sleep? We don’t need science to tell us that. But, if you do need more evidence, here are six science-based reasons why you should make getting getting enough rest a priority in your life.

1. Lack of sleep leaves you feeling fatigued, achy and disoriented.

2. Scientists know that sleep is important but can’t explain exactly why. Brazilian scientists speculated that sleep is critical for protein synthesis.

3. Lack of sleep causes tissue breakdown marked by increases in catabolic hormones such as cortisol and decreases in anabolic hormones such as testosterone and insulin-like growth factor 1.

4. Inadequate sleep slows pathways involved in protein synthesis, increases protein breakdown, and promotes loss of muscle mass and muscle degradation.


5. In athletes, inadequate sleep slows injury repair and tissue recovery.

6. In older adults, sleep deprivation can contribute to sarcopenia — the loss of muscle tissue.
