Well, statistics have is that 50% of us have problems sleeping.

Discussion

According to Krakow in his book Sound Sleep, Sound Mind (2007), experts have discovered that sleep is divided into four stages. Each stage of deep sleep is deeper than the last. Each period of deep sleep is punctuated by periods of REM or rapid eye movement sleep.

Important information on sleep according to Billiard in his book Sleep (2003) is that, while an individual is in the REM stage, some of the characteristics witnessed are rapid inhaling; the limbs and eyes are partially weakened. The brain at this stage is still very active just like a person is alert. The heartbeat goes up, in the case of men, erection appears and the entire body is unable to control its temperature.

At this stage, individuals experience dreams and can easily recall them once they are woken up. Studies indicate that a normal person undergoes three to five stages of REM every night. The first stage is characterized by little sleep where one keeps on falling asleep on and off and therefore any slight interruption wakes you up. In this particular stage, both the eyes and muscles are in slow motion.

In the second stage, the eyes stop moving and the concentration of the brain is lowered and its performance becomes occasional.

In the third stage, the concentration of the brain is very low and the delta is replaced with much faster movements.

The very last stage is characterized by extremely high delta and an individual who gets in deep sleep were not easy to wake up. In the third and fourth levels, the eyes do not move and the muscles are completely dormant. These two stages are associated with nightmares in kids alongside wetting the bedding.

Sleep is a natural, vital and restorative process. As we get older our sleeping patterns may change but we still need the same amount of recommended sleep. The consequences of the lack of sleep include slow thinking or reactions, difficulties listening and understanding. We make frequent errors or mistakes when we are tired and suffer from poor judgment, impatience, and even depression. It is clearly visible that, when one steals from sleep thinking that he will compensate on another day, a condition referred to as sleep debt occurs and it is very dangerous.

Experts suggest that the amount of sleep we need differs as we grow. A newborn baby will sleep for sixteen hours of the day. A child at five or six will start to need ten or eleven hours. The right amount for every teen and adult is eight to nine hours of sleep a night. Some people exist on cat naps. Yet we all need this vital and important rest.

In conclusion, this short speech has shown you why it is important to have enough sleep. It is evident that, when one does not get enough sleep, it poses a big threat to our health. Although it might take time to notice, continuous loss of sleep can bring epidemics later in life, in the case of young people.

Finally, just like the way an individual cannot survive without air so is sleep.
