How better sleep strengthens every other lifestyle pillar
Sleep is not simply a time when your body shuts down. It is an active biological process that allows your brain and body to recover, repair, and prepare for the next day. During sleep, memories are consolidated, hormones are regulated, tissues are repaired, and countless physiological processes work together to maintain your long term health. Chronic sleep deprivation increases the risk of heart disease, diabetes, obesity, depression, impaired immunity, and cognitive decline.
​
