Why Do We Need Sleep
- Learning & Memory - Sleep can help to solidify new information you've learned in your brain. It can also recover and organize memories.
- Mood Enhancement - The part of your brain that controls your emotions and decision making slows down while you sleep allowing optimal performance when awake. REM (Rapid Eye Movement) is especially important for a good mood during the day. Those who lack sleep can get easily frustrated and grumpy.
- Immune System - Without adequate amounts of sleep, the immune system becomes weak, making you vulnerable to infection and disease.
- Growth & Development - When you sleep well, your body produces human growth hormone. A drop in your natural production of HGH is a scary path to getting fat. HGH stimulates the metabolism and increases the body's ability to burn fat and increase muscle size.
The amount of sleep that you need depends on many factors - your genetic make up, your daily activities, the amount of exercise you get, your age and the quality of your sleep.
Most adults, on average, need between 7-8 hours of sleep. Some may be able to function on as little as 5 and some may need closer to 10.
Sleep deprivation will be felt both physically and mentally. Listen to your body and give it the sleep it needs. Getting on a regular sleep schedule is best especially if you have problems getting a good nights rest.
