ABOUT SLEEP

A neuro-signaling chemical called neurotransmitters regulates whether we are asleep or awake by acting on nerve cells in the brain, or on different groups of neurons. The neurons in the brain that connect with the spinal cord in the brain produce neurotransmitters such as serotonin and norepinephrine, which keep parts of the brain active when awake. When we are asleep, other neurons begin signaling at the base of the brain. Research shows that when we wake up, a chemical called adenosine is formed in our blood and causes drowsiness. This chemical breaks down slowly during sleep. Because sleep and wakefulness are affected by various neurotransmitter signals in the brain, foods and medications that alter the balance of these signals can affect whether we are alert or careless and how well we sleep. Caffeinated beverages such as coffee and drugs such as diet pills and decongestants can stimulate parts of the brain and cause insomnia, or insomnia. Most antidepressants suppress REM sleep. Heavy smokers often fall asleep too easily and reduce the amount of REM sleep. They wake up even after 3 or 4 hours of sleep due to nicotine withdrawal. Lots of people who suffer from insomnia try to solve the problem of alcohol . Alcohol helps people fall asleep easily, which also robs REM and more deep sleep. Instead, it keeps the light stages of sleep, allowing them to wake up easily.

The amount of sleep that each person gets depends on many factors, including age. Babies usually need 16 hours a day, and adolescents need an average of 9 hours. Although some people need 5 hours or 10 hours of sleep every night, for most adults, 7 to 8 hours of sleep a night is best. During the first 3 months of pregnancy, women need many hours more sleep than usual. People sleep more easily and for a shorter period of time as they get older, although they usually need as much sleep as they do in adulthood. About half of people over the age of 65 often have sleep problems, such as insomnia, and in most older people, the condition of deep sleep is often greatly reduced or completely stopped. This change may be a normal part of aging or may be the result of medical problems commonly seen in the elderly and with medications and other treatments for those problems. If a person has sleep deprivation in the previous days, the amount of sleep will also increase. Too little sleep creates a “sleep date” that is like an overdrive at the bank. Eventually, your body will want to repay the loan. It does not seem to be enough to get less sleep than we need; As we get used to the sleep deprivation schedule, our decisions, reaction times and other tasks are still weak.

Although scientists are still trying to figure out why people need sleep, animal studies show that sleep is essential for survival. For example, mice typically live two to three years, while REM insomniacs live an average of only 5 weeks, and insomniac mice live only 3 weeks. . Sleep deprived mice develop unusually low body temperatures and have lesions on their tails and feet. Injuries develop because the rats’ immune system is weakened. Some studies suggest that lack of sleep can adversely affect the immune system. To maintain the functioning of the nervous system

Sleep is essential for our nervous system to function properly. Too little sleep can discourage us and make us unable to concentrate the next day. This leads to impaired memory and physical performance and decreased ability to calculate mathematics. If sleep deprivation persists, hallucinations and mood swings may develop. Some experts believe that the use of sleep gives neurons the opportunity to wake up when we are awake and repaired. Without sleep, neurons may have low energy or be contaminated by byproducts of normal cellular activity, which begin to degenerate. Lack of sleep gives the brain the opportunity to learn important neural connections that can be impaired by a lack of activity. To raise ourselves

Deep sleep is similar to the release of growth hormone in children and adolescents. As in deep sleep many cells in the body reduce the production and breakdown of proteins. Since proteins are the building blocks needed for cell growth and damage from factors such as stress and ultraviolet rays, deep sleep can actually be “aesthetic sleep”. During deep sleep the parts of the brain that control emotions, decision-making processes and social interactions are significantly reduced, indicating that this type of sleep maintains proper emotional and social functioning in awake people. A study in mice showed that some of the neuro-signaling patterns that arose during the day during deep sleep were replicated as in mice. This model helps to encode repetitive memories and improve learning.

Sleep and sleep problems play a role in a large number of human disorders and affect almost every field of medicine. For example, problems such as stroke and asthma attack are more likely to occur at night and in the morning, possibly due to hormonal changes, heart rate and other sleep-related symptoms. Sleep can also affect some types of seizures in complex ways. Lack of sleep can also trigger seizures in people with certain types of epilepsy. Effect of sleep on the immune system

Almost everyone with a mental disorder with depression and schizophrenia has sleep problems. For example, people with depression may wake up in the morning and not be able to sleep again. The amount of sleep a person gets can strongly influence the symptoms of overall mental disorders. Sleep deprivation is an effective treatment for some types of depression, but it can also lead to depression in others. Excessive sleep deprivation can lead to a mood of insanity and hallucinations in healthy individuals, and interrupted sleep can trigger episodes of mania (anxiety and hyperactivity) in people with depression.
