This is a small bit of note which I read very long back. Its an important part for our life. Every individual seeks, wants and even ready to pay as much as money as required. Ya it’s all about our sleep. Sleep is a temporary state of unconsciousness that restores the Neuro transmitters which are utilized in the course of the day. (Neuro transmitters are chemical messengers used in nervous system for its routine function). In addition, the non-stop organs such as heart and lungs relax during deep sleep and work with ease. That is why the heartbeat respiratory rate and B.P. come down during deep sleep.
Though it depends on the physical and mental activity, normally 6-8 hours of sleep is sufficient for an adult to replace Neuro transmitters.
There are two types of sleep. Deep sleep or dreamless sleep and superficial sleep or dreamful sleep.
In the course of the night, normally we start with deep sleep for about 90 minutes. And this is followed by 20 minutes of superficial sleep and once again there is a repetition of this cycle as long as we sleep. Deep sleep relaxes our body, reduces our basal metabolic rate and refreshes us. The deeper the sleep a person has in the night. The more refreshing he will be on waking up.
Superficial sleep is associated with dreams, rapid eye movement, increase in heart rate, irregular breathing and is not very refreshing.
It also leads to nightmares, teeth grinding and hallucination. A technique such as meditation is very good and exercises help to eliminate superficial sleep and induce deep sleep.
Do not sleep if you are really not sleepy, as superficial sleep has no positive effect on your body. But the most important thing is, we must feel fresh after getting up from sleep. Otherwise the real benefit of sleep is lost!
