The need to sleep for each person is different, but adults usually need 8 hours of sleep per day. If too little or too much, there will be some health problems both physical as well mental. For example, a study conducted by the American Association of Cancer Research in 2008, when a woman has a pattern of sleeping less than 7 hours, the risk of breast cancer will be 47% greater than in women who had normal sleep patterns.
In addition, a study published in the Journal of Sleep 02.08.2010 also states that people who sleep only 5 hours per day had a two times greater risk of developing heart disease than those who sleep normally.
While someone who is too much sleep up to 9 hours per day, the risk increased to 1.5 times for heart disease.
The body will usually give a signal when a person experiences a lack of rest or sleep. Reported by Metrotvnews, Dr. Andreas Prasadja from Mitra Kemayoran Hospital provides some characteristics when a person experiences a lack of sleep =
- Hard to wake up in the morning, waking up with difficulty.
- Often forget where to put something or other things.
- A lot of mistakes when writing or typing.
- Careless when working.
- Hard to concentrate.
- Sleep when not sleepy.
If you have all these characteristics, it is certain that you have a lack of sleep or lack of rest time. Sleep immediately so as not to run into a lot of other health problems.
