our well-being, mood and activity changes under the influence of external factors.This time of year, and the pressure and environmental conditions in the place where we live.
However, the capacity of man depends on himself, on his ability to organize their activities so as to be as efficient as possible.
Everyone knows about the art of time management, knowledge which can save up to 5 hours per day, without reducing the normal volume of cases.But no way to time management will not help if the person is ruptured and is in a state of extreme exhaustion.
Why do we get tired?
so-called acute fatigue - this is a normal protective reaction of the body, which sends signals to the brain that the resources to the limit, you need to take time off work or reduce the load.However, if a person repeatedly ignores the warning, the state of fatigue may become chronic, leading to an overall reduction of efficiency and activity.Extreme fatigue is an expression called fatigue, which can already be considered a disease.This condition occurs when a person for a long time, not enough sleep, when his work is organized properly and there is no time to rest.All this is fraught with the development of systemic diseases, nervous breakdowns, as a minimum.When extreme fatigue may occur more serious violations.
To not bring themselves to extremes, we must remember that human performance and its dynamics, in the first place depends on the time that you allocate to sleep and rest.
wonderful power sleep
This mysterious process is still not fully understood by scientists.This is the best way to restore all body systems.From properly organized night's sleep depends primarily on human performance.Let us consider what it benefits.
When we sleep, our brain continues to function, but its activity is not of such a nature as in the waking state.Based on analysis of EEG data were identified five stages of sleep, there are five forms of brain activity.
first stage of sleep - it's shallow slumber, when the person is still on the verge of waking.The more time passes from the moment of falling asleep, the deeper sleep.
greatest importance to us are two stages - a deep and REM sleep.
Deep sleep
It is called so because during this stage of the human body to the greatest extent can not influence the surrounding stimuli.Simply put, a person at this stage is difficult to awaken.The duration of this phase decreases with age, and most pronounced among children.It is hypothesized that during this period, creating favorable conditions for the growth and repair of the body.This phase, most often occurs within 40 minutes after falling asleep.All processes in the body at this time, slowed sharply, a man lies motionless and completely relaxed.
REM sleep
This species is also called paradoxical sleep or rapid eye movement.The latter name is due to the fact that during this phase of human eyes move rapidly ages od.The paradox of this stage is also in the peculiarities of EEG, which gives a picture similar to the waking state.
At this stage, we dream the most vivid dreams.While in this phase, people can walk in his sleep, talk, perform various movements.It has been proven that this phase is "responsible" for the restoration of mental and brain activity.Furthermore, it is important to get rid of various diseases.If a person does not sleep for a long time, then, first of all, it lacks precisely this phase.
human performance is related to how many times during the night phase of deep and REM sleep have replaced each other.That is why it is recommended to sleep at least 7-8 hours.
the best time to sleep
best bedtime - individual characteristic, and depends on your preference.However, in this case, there are a number of laws.For example, sleep until 12 o'clock at night causes an increase in efficiency and that it is important for women helps to preserve beauty.
terms of circadian rhythms, while the maximum fall in activity and performance - a period from 2 am until 5-6 am.It is now considered the most dangerous, for example, on roads.Consequently, better and healthier it is just time to sleep.If this is not possible, it is necessary to minimize the activity and give yourself the opportunity to rest a bit.
human performance - a dynamic characteristic.It does not happen consistently high in some moments may decline.But the main condition for health and activity - it is well-organized recreation, which will prevent fatigue and give you the opportunity to enjoy life in all its manifestations.
