On average, we need about eight hours of sleep every night.
Sleep refreshes the body and mind.
People who don t get enough sleep may have problems with daytime fatigue, reduced concentration and lowered productivity. Lack of sleep impairs the ability to reason, learn new concepts, or recall previously learned material. Sleepy drivers are believed to cause more than 100,000 traffic accidents and 1500 deaths. If you find yourself waking up to use the bathroom at night, limit the amount of fluids you drink before bedtime. Avoid long naps during the day, which can interfere with your ability to sleep at night.
