Sleep plays a vital role in good health and well-being throughout your life. During sleep, your body is working to support healthy brain functioning and maintain your physical health. The damage from sleep deprivation might not hurt you instantly but it’s a safe bet it will harm you over time if it continues for a long time. For example, ongoing sleep deprivation can raise your risk for chronic health problems such as depression, high blood pressure, obesity, diabetes, and various heart problems.
