1. Chronic Disease

Chronic sleep deprivation has been tied to higher risks of Type 2 diabetes, cardiovascular disease, obesity, and depression, the CDC reports.

Sleep loss is associated with an increase in appetite that is excessive in relation to how hungry you are when you’re well-rested, research shows. It's also noted that the increase in obesity rates coincide with a decrease in self-reported sleep habits.

3. Cognitive Performance

Significant cognitive impairments from sleep deprivation can affect your performance during ordinary tasks like driving and operating machinery.

A lack of sleep can interfere with your body’s ability to fight off infections. Research shows sleep and your body’s internal clock, known as the circadian system, regulate your immune system.
