How Long We Need Sleep?

More than a few decades people used to sleep for eight to nine hours at night. However, in the world of  Internet, tight deadlines, and increased stress, as now it is clear that our sleep needs reduced, too. When compared with several years ago, now the average person only slept about six hours every day. The data  in 2009 only 28 percent of Americans who slept eight hours a day. This amount is reduced from 2001 which reached 38 percent.

Various studies have shown the importance of sleep to support health. Lack of sleep is known to cause obesity, the risk of diabetes and heart disease, improve mental disorders, like depression and reduced concentration.
Despite lack of sleep harm health, it turns out the excess of sleep is also not recommended because of too long duration of sleep also increases the risk of disease.

Although there is no magic number of experts recommended to sleep at the right time, but adults are advised to sleep 7-8 hours every day. It is also not absolute, because it turns out the quality of sleep is more meaningful than the duration of sleep.

Sleep needs of each person is also allegedly associated with genetic and environmental factors. What's important is we keep fresh the next day and can move optimally. With increasing age, sleep needs change. In the elderly for example, decreased ability to sleep and sleep quality also decreased too.

When we sleep, almost all organs of the body is stopped or slowed, except the brain remains active. At this stage of REM sleep (Rapid Eye Movement), the brain is maximal in data processing and memory, which sometimes appears as a dream. Characteristic of REM sleep is the presence of eye muscle movement, hands, or feet.


At this REM stage of growth of brain cells take place quickly. In addition to dreams, sometimes delirious children. It's a normal thing. Meanwhile, non-REM sleep or quiet sleep stage is very important for the physical growth of children. At this stage occurs repair body cells and growth.

This happens because during sleep the body will release growth hormone which will stimulate the liver to produce substances of bone and muscle growth.

In adulthood, growth hormone is switching function. He will serve for the maintenance and repair of body tissues, in addition to accelerating the growth process. Another benefit of sleep is taking part in improving the child's body resistance against infection. This means that children who sleep less are more susceptible to disease.

Well, if you remember your dreams, try to record. It as a material reflection for us. Additionally it was also useful for self-development.


Pent-up emotions
Many artists produce masterpieces by pouring the contents of his dream into a post, such as Mary Shelley's Frankenstein. From the same dream one can get inspiration to answer the problem at hand.

Dreams are subconscious way while it is resting. Dreams are also a manifestation of all the emotions that can not get out when someone in a conscious condition. Therefore, the nature of this dream is very personal.

Freud believed that dreams are a safety channel for pent-up emotions that can not be expressed in while awake. Emotions or feelings are suppressed during waking may be released in a healthy manner through a dream.

Dream by many researchers called sleep mentation, for example, is closely linked with emotions. This means the quality of a dream influenced by the emotional state prior to sleep.

Someone who is anxious frequent nightmares to disturb the sleep and wake up at night. Someone who often have nightmares do not necessarily suffer from depression or excessive anxiety. This could be due to his hobby of watching a horror movie.


What happens in dreams that are strange and unreal. However, emotions are going really real. For example, if the dream of meeting a lover, when awake, your heart will flowered. Conversely, if the dream to meet a terrorist, when you wake up, heart still pounding.

Unlike the fetus is 100 percent are in phase of REM sleep and a newborn that 50 percent of sleep in REM phase, the adult phase of REM was only 20-25 percent. REM sleep in this phase is very important for the growth and development of infants and children. Because in his sleep, growth hormone is important will be issued.

REM phase is also important for adults. So important that the REM phase so that when someone is lack of sleep and then sleep, the brain directly into R sleep stage, without passing through proper sleep architecture. Condition is called sleep-onset SOREM or REM.
