What Is Sleep?
Sleep considered just a block of time when your brain and body shut down. Each stage of sleep is a specific type of brain waves. Thanks to years of research, we now know that dream is a cycle of a few degrees.
Sleep consists of two basic types:
-Rapid eye movement (REM) sleep and non-REM sleep (with three different stages).
In stage 1 non-REM sleep, you sleep easy and can wake up.
During this first stage of sleep, your eyes move slow your muscles relax, and your heart and breathing begin to slow. You then enter stage 2 non-REM sleep, when slower brain waves. You spend about half the night at this stage. When you are into stage 3 non-REM sleep, then your brainwaves become even slower, and the brain produces most slow waves almost only (called Delta waves). Stage 3 is a deep stage of sleep, during which it is difficult to be awake.
Children who wet in a bed or sleepwalk, tend to do so during stage 3 of non-REM sleep. At this stage, people dream and they are the deepest sleep. Then eyes speed ranges, although the shutters closed, breathing is short, fast, and irregular, and heart rate and blood pressure increase. But, why people dream and why REM sleep is so important are not well understood. The only thing is that REM sleep stimulates the brain regions you use to learn. Other stages are important for being able to create a memory.
What Makes You Sleep?
There are two substances produced by our body that causes us the need and necessity of sleep. One substance called adenosine builds up in our blood while you’re awake. Then, while you sleep, your body breaks down the adenosine. Levels of this substance in our body may help trigger sleep when needed. That may cause you to sleep longer than normal. The other substance that helps make you sleep is a hormone called melatonin. This hormone makes you feel sleepy at night. It is part of your internal “biological clock,” which controls when you feel sleepy. But some people work at night, which causes their biological clock works in the other way. Those who have a problem with the biological clock work the other way around, which can cause various psychological and mental consequences. Other factors also can influence you to need to sleep hormones called cytokines. Cytokines are to help the immune system fight certain infections or chronic inflammation and may prompt you to sleep more than usual. All these listed substances produced by our body are important for a good and healthy sleep.
What Does Sleep Do for You?
Important functions in our lives are connected with the quality of sleep. So, it is important to have healthy and normal sleep. Your Learning, Memory, and Mood. The well-rested people be better to remember and to gather information. Good night’s sleep is important for human memory. It’s important to get enough rest the night before a mentally challenging task.
But is not good for sleeping for a short period of waiting to sleep until after the task is complete. Night’s sleep is essential for every human being. That is important because night sleep gives our bodies and minds enough force and energy. Even if you don’t have any challenges during the day, you should still get enough sleep. People who suffer from a lack of sleep, are at risk of developing depression. People who don’t get enough sleep is the mother of newborns. For them, it is normal to appear to depression as a result of insufficient sleep overnight.
Sleep gives the needed rest for your heart and provides the necessary energy. If you don’t get enough sleep, the nightly dip in blood pressure, may not occur. Then various problems may arise from the vascular system. A lack of sleep also puts your body under stress. So, can trigger the release of more adrenaline, cortisol, and other stress hormones during the day. These hormones keep your blood pressure from dipping during sleep, which increases your risk for heart disease. Also, may trigger your body to produce more of certain proteins. This protein is C-reactive who is the reason for increased risk for a condition called atherosclerosis, or hardening of the arteries.
Deep sleep (stage 3 non-REM sleep) triggers more release of growth hormone. That contributes to growth in children and boosts muscle mass and the repair of cells and tissues in children and adults. Sleep’s effect on the release of sex hormones also contributes to puberty and fertility. During sleep, your body creates more cytokines—cellular hormones that help the immune system fight various infections. Lack of sleep can reduce your body’s ability to fight off common infections. Although, sleep is a powerful regulator of appetite, energy use, and weight control. Have a problem that they do not sleep at night and eat overnight. Increasing their body weight and cause a risk factor in the preparation of diabetes. So, it is important to have a good sleep because during sleep hormone products are to control blood sugar levels, and blood pressure.
How Much Is Sleep Enough?
And finally, we reached a significant moment about everything that we’ve talked about. That is how much time is enough for sleeping. Sleep varies from person to person and at a different age. The correct answer with certainty since no one can give. For some people, it is enough to spend 7 hours in sleep to be able to work further. But, another 8-9 hours or more is enough for being fresh. All this depends on the individual and each body. As people get older, the pattern of sleep also changes. Older adults tend to go to bed earlier and wake earlier. Thus becomes clearer why older people need more sleep than younger. Especially to those who have entered into puberty. But, children and babies need more time spent in sleep. That is because they need more sleep for good growth and development. Now we see that every period of life is different in stages of sleep. Good sleep means good health. So you spend enough time to rest and sleep. It will help you to overcome all the obstacles that are giving you today’s lifestyle.
