How important is your sleep ?
Sleeping should not be neglected because it`s an essential part of life . In many dictionaries sleep is defined like a state of relaxation ,- it s a normal physiological state and periodical inactivity which is needed to regain strength characterized by total or partial termination of conscience functioning through muscular relaxation , through slowing down the circulatory system and breathing and by dreams ; the state of a person who is asleep , differs from the watch state .
Actually this definition as many others it s not completely true . The state of sleep like the state of watch it s an active physiological process that imply`s interaction of more components of the central nervous system and the autonomic nervous system . (vegetative).
Even thou sleeping is represented by an apparent state of calm , during sleep time several complex brain changes may occur , changes that cannot be explained by a simple physical and mental rest (mental). For example some brain cells during sleep have an increased activity 5-10 times bigger than usual activity during the watch state. . Two essential features make the difference among sleep and waking: first is that sleeping has a high perceptual barrier among awareness and the world outside , second that a sensorial impulse (like a loud noise} could overcome this barrier and awake the person who is sleeping .
When we sleep . every 60-90 minutes were going through a phase where we have a couple of sudden eye moves , the REM sleep . In this stage , brain is very active and according to researchers it deploys some kind of regeneration. Some experts say that when this cycle is not complete and we do not get enough sleep we have an accumulation of negative affects on our body . This way the brain functions are affected causing poor performance and numerous diseases.
Sleep is disturbed by substance like caffeine, alcohol, drugs or nicotine , so if we avoid using these substances it will helps us a lot to sleep better . Some substances like caffeine can temporary block the production of chemical compounds that announce the need to sleep . However the brain has a mechanism that triggers sleeping when we have not got enough of it . resulting the so called micro sleep episodes . According to The TorontoStar, ” no matter what we do the brain who did not got enough sleep will periodically come into the first phase of sleep , which can lasts from 10 seconds to a minute” . Imagine that you are behind the wheel driving at 50 km / h, and you have a sleep episode of ten seconds . In this short time , you will drive a longer distance than a football field . Sleep deprivation can weaken the immune system, only during sleep our body produces T cells who fights pathogens . Also during sleep time our body secretes leptin , a hormone which is responsible for our appetite . Therefor our body needs sleep same way we need a healthy nutrition and workout .
Physical activity practiced in moderation, helps us to improve the quality of rest and sleep . Lack of workout doesn’t not help sleep and reverse , because if we exaggerate with our workout , especially in the evening , stimulates the production of adrenaline, which causes excitement and fatigue . So if we go to the extremes it wont help our sleep at night . insomnia is a symptom of psychological problems, as in the 85-90% of cases , the advice is to approach the situation with the most appropriate therapeutic methods . By eliminating factors that lead to anxiety, stress, depression, etc .. it will allow us to solve also the insomnia , otherwise it will continue to aggravate our existing problems.
Some external factors , such as: excessive noise, heat, cold, light can be controlled , and simple technical measures can sometimes be plenty to sleep well . Sometimes insomnia needs meds (sedatives, hypnotics, anxiolytics), Medication should always be prescribed by (your) doctor . Medications should be taken with caution when necessary respecting the quantities and directions , because the have many side effects and is likely to exceed the prescribed dose . Induced sleep differs with natural sleep , actually the REM sleep and the deep sleep is in different proportions . Who is using this substance to be able to sleep has only 50 % from a deep sleep . Drug abuse or using them for a large period of time will creates addiction , and once you stop taking them it will create an abstinence crisis.
