  • Sleep lets you heal. Sleeping puts your body in an unconscious, relaxed state. Since you're not exerting any physical energy while sleeping, your body can channel this energy into healing. Sleeping allows your inflammation, bruising and swelling to go down and even triggers the release of hormones that grow tissue.

  • Sleep reduces anxiety and depression. After surgery, there is an emotional healing that must take place. A lot of patients also experience post-op depression. Sleep is hugely important for fighting mental exhaustion and hitting your emotional reset to put your all into recovery.

  • Sleep gives you the energy you need for ReHab. Working through your at-home ReHab routine, physical therapy, and everyday tasks require extra energy when you're in physical pain. If you're not sleeping at night, you're not going to have the physical or mental stamina to perform your best and recover as quickly as possible. 7-8 hours of sleep at night is linked to a better emotional mood, less depression, better health, faster healing, and fewer accidents.
