Sleep

Sleep is a naturally recurring state of reduced consciousness and responsiveness, essential for physical and mental health. While you’re sleeping each night, you might experience cycles of light and deep sleep, with dreams occurring primarily during the REM (rapid eye movement) stage. Consistent, quality sleep supports cognitive function, emotional regulation, and overall health, reducing the risk of chronic diseases like type 2 diabetes, obesity, and heart disease. Lifestyle factors, such as maintaining a regular sleep schedule and creating a conducive sleep environment, can help you achieve optimal sleep.[1]
