The importance of a good night sleep and the absence of sleep disorders:

For most people sleep means a period of inactivity. But you should know that all kinds of processes are active in our body and mind during sleep. The sleep involves a natural rhythm that starts in the evening when the pineal gland produces melatonin, a hormone that signals the time for sleep. When the person is ready to sleep, he is breathing heavy, he has soften muscles, the heart beats slower and body temperature decreases. In this phase, the brain waves are changed. From stage 1 to 3 brainwaves slow down and finally in phase 4 we enter in a deep sleep with very small undulations. After a phase of deep sleep follows a phase called REM (Rapid Eye Movements), in which our eyes move rapidly and there is almost the same brain activity as when we are awake. In this phase the muscles are the most relaxed. The most important phase of the sleep is without doubt the one in which it is the secretion of a number of hormones necessary for growth, regulate energy and affecting metabolic and endocrine functions. During sleep our body is actually rebuilt after all the activities during the day. It seems that depending on the severity and type of disturbance during sleep, different physical and mental consequences appear. A few hours of sleep deprivation per week can make the hormones to not be maintaining stable. Furthermore, it affects the body’s ability to cope with stress and to process carbohydrates. An interrupted sleep also causes a decrease of  leptin hormone. Low leptin levels lead to cravings for carbohydrates. Sleep deprivation, and repeated awakenings will seriously undermine our physical performance. Moreover, it seems that other phases of sleep disruption could have an effect on motor skills. An uninterrupted, undisturbed sleep is of major importance.

Consequences of sleep deprivation:

• reducing the thought process and delaying the response time.
• problems in hearing and in understanding the instructions.
• memory problems.
• frequent mistakes.
• narrow field of attention; tendency  to overlook important changes.
• mispricing the complex situations.
• trouble in finding new solutions.
• narrow vision; narrow field of vision.
• blurry vision.

How sleep deprivation affects behavior:

Scientific research has shown that interrupted sleep affects our behavior and feelings . This way appear:
• stress
• depression
• agitation
• dissatisfaction
• sadness
• anxiety
• mental exhaustion

How much sleep do we need?

The need for sleep is different for everyone, but on average an adult needs between 7 and 8 hours for a  healthy sleep. It seems that people who need more than 8 hours of sleep do not sleep optimally.

Conclusion:

For an optimum sleep is very important  the silence in the bedroom, the absence of light, the right temperature and sufficient amount of oxygen in the bedroom. For people suffering from allergies is very important to keep the bedroom free of dust. Also a hard surface on which you sleep should be avoided.
