Many critical restorative functions in the body occur during sleep. Even though we are not conscious while we sleep, the brain and body are extremely active undergoing processes to help the body recover from the day before. Sleep is also crucial for strength training recovery and helps support the muscle-healing process. The body actively repairs and builds tissues during sleep. Hormones are also released to support overall muscle development. It’s important to secure quality sleep each night and allow the body to cycle through all five stages at least four to five times each night.
Stage One. Lightest stage of sleep
Stage Two. Disengage with surroundings
Stage Three and Four. Beginning of deep sleep. Muscles relax, blood supply to muscles increases, and recovery can occur.

However, more is not always better. More sleep does not equal increase muscle recovery. Keep moderation and balance in mind and find what works best for you. In addition, the recommended ranges are good to abide by, however it’s important to understand your own body and needs. Determine how much you sleep you need according to how you feel. Some may feel that they need less than recommended or more – adjust accordingly so you feel renewed each day. Not only is time important, but also securing consistent uninterrupted quality sleep each night is important. Remember the body should cycle through the five stages of sleep at least four to five times each night.
