Acutally it is essential not to underestimate the importance of sleep. Sleep is the most important factor contributing to your well-being and your appearance. An adequate sleep quota is one of the best defense mechanisms we have to stay healthy and manage stress. Sleeping is a physiological function as essential for our body and mind as eating and drinking water. It is not a luxury: it is an essential requirement to ensure our mental, emotional and physical health. When we sleep badly, every facet of our lives can be affected, such as our relationships with others, our performance at school or work, our appetite, and our energy levels. The hours of sleep lost really have harmful consequences. In general, most healthy adults need an average of eight hours of sleep a night to be in shape the next day.
Sometimes considered a waste of time, sleep is necessary for the proper functioning of the body and the proper regeneration of cells. The body, during the night, works in slow motion. The breathing, the heart rate, the muscle and arterial tension slow down. The body also produces new cells to replace dead cells. As for the brain, it takes advantage of the sleep phase to “sort” the information it has received throughout the day. Indeed, we assimilate what we learned during the day during the night. As a result, bad sleep is synonymous with poor information assimilation. In addition, poor sleep has consequences on concentration and learning. Sleeping poorly or not enough, causes easy distraction and more difficulty staying focused on a task.
Here are several points on which your sleep may have some impact:
The different phases of your sleep
Slow, light sleep covers about half of our total sleep time. This is the moment when the sleeper goes from waking to deep sleep. The brain activity slows down, the muscles begin to relax … At this point, it remains easy to wake up.
Deep slow sleep
It represents about a quarter of our sleep time. During this phase, the heart rate and breathing slow down considerably, the body temperature drops, the muscles relax completely … The body can then begin to create hormones and renew its cells. During deep slow sleep, the body really starts to rest and recovers deeply.
The phase of paradoxical sleep is the phase during which one dreams. During this cycle, breathing and heart rate are very irregular, eye movements are very fast, body temperature is fluctuating … As for the brain, it runs at full speed! Electroencephalographic tracing shows that the brain activity during the paradoxical sleep phase is close to that of wakefulness.
