You may have this idea that you’re not getting enough sleep. Chances are, you’re not. There’s a big difference on our performance when we have adequate sleep every night versus when we don’t have enough. So, how much sleep do we actually need? About some 15 years ago there was this theory that if you get about 4 to 5 hours of sleep a night then your body will just adapt and the brain can still be able to perform well. But that was because the studies conducted then were on participants who were only monitored during sleeping time at night. They were able to go home by morning. They could also have taken a nap during daytime or they could have been drinking coffee.
Insomnia is a symptom which can accompany several sleep, medical and psychiatric disorders, characterized by persistent difficulty falling asleep and/or difficulty staying asleep. Insomnia is typically followed by functional impairment while awake.
Most adults have experienced sleeplessness at one time or another in their lives. An estimated 30%-50% of the general populations are affected by insomnia, and 10% have it as a chronic condition. Sleepless is a quite common problem but when it starts to become chronic, it becomes a big burden. Our body needs 6-8 hours of sleep. The older we become the longer hours of sleep recovery our body needs from every day’s stress. My teacher Dr. Denofrio used to say: “Sleep is your weapon.” If we are sleep deprived, we can’t function well and we easily get irritated and can’t concentrate. Insomnia is most often caused by stress, illness, a change of the sleeping environment and many other factors. There are five types of insomnia: Primary, Co-morbid , Transient, Short-term, and Chronic.
