What Less Than 8 Hours of Sleep Does to Your Body?

Sleep is one of the most important pillars of good health, yet many adults regularly get less than the recommended amount. While individual sleep needs vary, most adults require at least seven hours of quality sleep each night, and many function best with around eight hours.

Consistently sleeping less than this can affect nearly every system in the body, including the brain, heart, immune system, metabolism, and mental health. Understanding the consequences of insufficient sleep can help you prioritize healthy sleep habits and protect your long-term well-being.
