Those who believe that saving on sleep gains time for life are deeply mistaken. Adequate sleep is the key to good health, and therefore a high quality of life. People who do not get enough sleep on a regular basis are more likely to be overcome by depression, chronic diseases, problems with excess weight and skin. But this is not all the negative consequences of poor sleep.
The effect of sleep on health
Modern man has so much to do that he often breaks his sleep schedule. This can lead not only to feeling tired and feeling unwell, but also to more serious health problems. Night sleep is especially important for a person. If it is neglected for a long time, then the body loses its defenses, and the risk of developing many chronic diseases increases.
Inadequate sleep can worsen not only physical but also mental health: depression, nervousness, a feeling of irritation and aggression appear. The appearance and beauty suffer from a lack of sleep: eyes swell, dark circles appear, the skin fades and becomes more prone to dryness and disease.
The amount of sleep a person needs varies and depends on genetic, gender, age and physiological factors. But on average, it will take about 7–9 hours to get a good night’s sleep and rest. If, for a number of reasons, the sleep pattern is regularly disturbed, then efforts must be made to restore it as soon as possible, otherwise it can result in dangerous health consequences.
Decreased memory and brain function
Surely, many have noticed that after a sleepless night it is much more difficult to concentrate and make the brain work. Proper sleep plays an important role in the development of cognitive thinking, promotes learning and increases memory capacity. Lack of sleep, on the contrary, leads to a deterioration in vigilance, concentration, slows down decision making. Poor sleep negatively affects both short-term and long-term memory. The ability to learn is also reduced, which is why proper sleep is especially important for schoolchildren and students.
Increases the risk of cardiovascular disease
Good rest and sleep are essential for heart health. Research in 2000 showed that prolonged lack of sleep can increase blood pressure and reduce the activity of the sympathetic nervous system. People who sleep less than six hours have a greater risk of developing coronary heart disease, atherosclerosis and stroke compared to those who sleep seven to eight hours a night.
Weakens the immune system
Lack of sleep can adversely affect the immune system, which protects the body from infections and viruses. When a person gets enough sleep, the immune system secretes substances that protect the body from infections. If the sleep pattern is disturbed, the production of cytokines decreases, which worsens the immune system, making the body vulnerable to various viral and bacterial diseases.
Poor sleep for a long time leads to changes in the production of neurotransmitters in brain tissues, which is one of the causes of depression. Sometimes depression itself prevents a person from sleeping. Insomnia is one of the first signs of depression. According to recent studies, more than 90% of people who have depression, anxiety and nervousness suffer from poor sleep.
Bad for the body
A regular sleep schedule helps maintain a good appetite and diet. When a person sleeps little, his body produces more of the hunger hormone ghrelin and reduces the production of leptin, which suppresses appetite. So, lack of sleep reduces appetite control and energy metabolism, which contributes to weight gain. In addition, there are many people who, with the help of food, try to overcome sleep or recuperate after sleepless nights, which is not reflected in the best way on the figure.
Worsening skin condition
Just one night of poor sleep can cause puffy eyes, dark circles under the eyes, and yellowish or gray skin tones. It is easy to imagine how much damage to the skin can be caused by a regular violation of sleep patterns. First of all, the skin loses its elasticity and healthy tone. Chronic lack of sleep leads to excessive feelings of stress and anxiety, due to which the body produces more cortisol. This hormone destroys a protein in the skin that is responsible for its elasticity and smoothness.
Skin that loses elasticity is more prone to problems such as dark circles around the eyes, dryness, wrinkles, dullness, etc. In addition, insufficient sleep reduces the skin’s ability to recover from sun exposure. Therefore, the path to her beauty and health lies, first of all, through a good sleep.
Like breathing, sleep is one of the basic human needs. It is almost impossible to be without sleep for a long time. And those who don’t get enough sleep on a regular basis have higher rates of premature mortality than those who keep a regular sleep schedule. According to the results of studies, rats that were not allowed to sleep died after 20–30 days. In 2007, studies showed that lack of sleep is as harmful to health and life as its excess.
Leads to accidents
Serious accidents on the roads and at work are often associated with uncomfortable sleep schedules and fatigue of the participants in the incidents. Driver drowsiness and fatigue can lead to car accidents and accidents. Lack of sleep impairs coordination, weakens memory and the ability to retain information, slows down reaction and decision making. All these factors adversely affect the ability to drive any vehicle or control mechanized production, which increases the risk of accidents. For those who work 24 hours a day, it is necessary to periodically arrange sleep breaks of at least 15–20 minutes. This will restore strength and save you from inattention.
Due to poor sleep, interest in intimacy is lost. A person becomes tense and irritated, which negatively affects the sexual life of both men and women. People suffering from sleep apnea (sudden stoppage of breathing while sleeping) tend to have lower testosterone levels, which leads to a drop in libido.
