Get the right amount of sleep

Scientific research makes clear that sleep is essential at any age. Sleep powers the mind, restores the body, and fortifies virtually every system in the body.

Setting sleep as a top priority may help to lower cortisol levels. Higher cortisol has been linked to chronic sleep problems such as obstructive sleep apnea, insomnia, or shift work. One review of 28 studies on shift workers found that those who slept during the day (night shift workers) had cortisol levels that were higher than those who slept at night (day shift workers). Rotating shift workers have been associated with impaired mental health, obesity, heart disease, type 2 diabetes, and other health problems. Additionally, the term "insomnia" refers to the inability to fall asleep. Numerous factors, including stress and obstructive sleep apnea, might contribute to it.
