1. Healthy Heart
+
Lack of sleep increases the risk of heart disease, research shows. Without adequate sleep, the body produces a hormone that can cause inflammation of the heart, which can lead to heart disease and stroke. Being short on sleep is also connected to high blood pressure, irregular heartbeat and increased levels of stress hormones.
2. Learning and Memory
+
Sleep helps the brain commit new information to memory. A process called memory consolidation occurs during sleep. While your body may be resting, your brain is busy processing your day, making connections between events, sensory input, feelings and memories. Getting more quality sleep will help you remember and process things better.
3. Metabolism and Weight
+
Chronic sleep deprivation may cause weight gain by changing the way our bodies process and store carbohydrates and by altering levels of hormones that affect our appetite. People who sleep less than seven hours a night are more likely to be overweight or obese.

4. Personal and Public Safety

Lack of sleep contributes to a greater tendency to fall asleep during the daytime. These lapses may cause falls and mistakes, such as medical errors, air traffic mishaps and road accidents.
5. Increased Energy and Alertness
+
A good night's sleep makes you feel energized and alert the next day. Being engaged and active not only feels great, it increases your chances for another good night's sleep.
