Sleep is crucial for maintaining and promoting overall health and well-being. During sleep, the body undergoes various restorative processes such as repairing damaged tissues, consolidating memories, and regulating hormones. Lack of sleep has been linked to a host of negative health outcomes including obesity, diabetes, cardiovascular disease, and cognitive impairment. It is recommended that adults get 7-8 hours of sleep each night to ensure optimal health. Prioritizing sleep and establishing healthy sleep habits can have significant positive impacts on both physical and mental health.
