Sleep Science
May 29, 2009
Sleep refreshes the brain and the body and is essential for every human being. Adults need at least seven to eight hours of sleep each day. Getting a regular seven to eight hours of sleep each day is a healthy practice. It is healthier than sleeping for longer or shorter periods of time.
The consequences of inadequate sleep
Studies have shown that people who sleep less than six hours or those who do not get proper sleep may have slower reaction times, less vigilance and worse short term memory. Patience and vision can also be affected by not getting enough sleep. Sleep is therefore essential for a person’s wellbeing. Inadequate sleep causes tiredness and stress. People who lack sleep tend to be aggressive and unfriendly.
The importance of sleep
Studies have shown that people who sleep well after practicing or learning a new task remember more information than those who stay awake all night and study.
Research has identified three stages of sleep: light sleep, rapid eye movement sleep and deep sleep. It is the deep sleep stage that allows the body to repair itself while rapid eye movement sleep repairs the mind.
People who sleep well also have a good immune system. Sleep also helps individuals lose weight. Those who get seven to eight hours of sleep regularly are more likely to lose larger quantities of weight.
Insufficient sleep has been linked with higher levels of stress hormones, called cortisol. These hormones are responsible for controlling our appetites when found in higher levels they increase our appetite; so we tend to feel hungrier and eat more.
A good night’s sleep not only helps you relax, but it also plays an important role in our appearance, making individuals look younger and better. Sleep also promotes healthy skin. Dark circles under the eye are most often caused by insufficient rest.
Tips to get better sleep
A good bedtime routine needs to be developed. You should have a regular schedule for when you go to bed at night and when you have to get out of bed in the morning. This routine should be strictly followed.
Do not exercise late in the evening as this increases the body’s temperature and makes it difficult to fall asleep.
Avoid alcohol, caffeine and cigarettes for at least three hours prior to your bedtime. Change your curtains to a dark tone to create a relaxing atmosphere.
