Sleep


sleep

 

A condition of body and mind such as that which typically recurs for several hours every night, in which the nervous system is relatively inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended.

 

Quick Facts:

 

  1. The average sleep requirement for college students is well over eight hours, and the majority of students would fall within the range of this value plus or minus one hour.
  2. Up to 60% of all college students suffer from a poor sleep quality, and 7.7% meet all criteria of an insomnia disorder.
  3. Good sleep can maximize problem-solving skills and enhance memory. Poor sleep has been shown to impair brain function.
  4. Snoring is the primary cause of sleep disruption for approximately 90 million American adults; 37 million on a regular basis.
  5. People who don’t get enough sleep are more likely to have bigger appetites due to the fact that their leptin levels (leptin is an appetite-regulating hormone) fall, promoting appetite increase.
  6. We naturally feel tired at two different times of the day: about 2:00 AM and 2:00 PM. It is this natural dip in alertness that is primarily responsible for the post-lunch dip.
  7. There are individual differences in the need to nap. Some adults and children need to nap. However, the majority of teenagers probably nap in the afternoon because they are not sleeping enough at night.
  8. Research shows that lack of sleep increases the risk for obesity, heart disease and infections. Throughout the night, your heart rate, breathing rate and blood pressure rise and fall, a process that may be important for cardiovascular health. Your body releases hormones during sleep that help repair cells and control the body’s use of energy. These hormone changes can affect your body weight.
