Sleep and Health: how sleep mode affects health by 50%

I. Introduction to the world of sleep: Architecture and stages

Understanding the influence of sleep on health begins with the awareness of the complex architecture of this process. Sleep is not just a state of shutdown; This is an active, dynamic period consisting of severalDistINC stages, each of which plays its own unique role in restoring and maintaining the optimal functioning of the body.

A. Circle rhythms: inner sleep conductor

Circat rhythms are internal biological watches that regulate many physiological processes during the 24-hour cycle, including sleeping, hormonal regulation, body temperature and appetite. These rhythms are synchronized with external signals, such as light and darkness, acting as a conductor that provides harmonious functioning of the body.

1. The role of the suprachiasmatic nucleus (SCN): SCN, located in the hypothalamus, is the main regulator of circadian rhythms. It receives information about the light mode from the retina and transfers it to other areas of the brain, coordinating their activity in accordance with the time of day. SCN operational disruption caused, for example, by changing time zones or working on a night shift, can lead to serious health consequences.

2. Melatonin: Hormone Darkness: Melatonin, the hormone produced by the pineal gland in the dark, plays a key role in sleep regulation. Its level increases in the evening, signaling the body about the onset of night and contributing to falling asleep. Light suppresses the production of melatonin, which explains why the use of electronic devices before going to bed may difficult to fall asleep.

3. Factors affecting circus rhythms: In addition to the light, other factors, such as the diet, physical activity and social interaction, affect circus rhythms. The regular regime of the day, including food and sports at the same time, helps to maintain the synchronization of circadian rhythms and improves sleep quality.

B. Stages of sleep: Traveling deep into the subconscious

The dream consists of two main phases: NREM (Non-Rapid Eye Movement-a dream without quick eye movements) and REM (Rapid Eye Movement-a dream with quick eye movements). NREM-SN is divided into three stages, each of which is characterized by certain physiological changes.

1. NREM-SN: Restoration of the body and brain:

   • Stage N1 (Speak): This is a transitional stage between wakefulness and sleep. The muscles relax, the heart rhythm and breathing slow down. It is easy to wake up at this stage.

   • Stage N2 (easy sleep): A deeper stage than N1. It is characterized by the appearance of sleepy spindles and K-comprehensive electroencephalogram (EEG). Sleepy spindles are involved in the consolidation of memory, and the K-complexes in the suppression of external stimuli.

   • Stage N3 (deep sleep): The most restorative stage of sleep. The heart rhythm and breathing slow down as much as possible, the muscles completely relax. The development of growth hormone reaches a peak. Awakening at this stage is difficult, and a person feels disoriented. A deep dream plays an important role in physical restoration, strengthening of immunity and consolidation of declarative memory (memory of facts and events).

2. REM-SN: Mental Processing and Dreams:

   • Rem-sne characteristics: It is characterized by quick movements of the eyes, rapid and irregular breathing, increased heart rhythm and blood pressure. The muscle tone is significantly reduced (atony), which prevents the implementation of dreams in physical actions.

   • Rem-Sna role: REM-SN plays an important role in the consolidation of procedural memory (memory and habits), emotional regulation and creative thinking. During REM-SNN, the processing and integration of information received during the day occurs. Dreams arising in REM-SNE can be associated with the processing of emotional experiences.

II. Influence of lack of sleep on physical health

A chronic lack of sleep has a destructive effect on all body systems, increasing the risk of developing various diseases and reducing the total life expectancy.

A. Immune system: Weakened protection

The lack of sleep weakens the immune system, making the body more susceptible to infections and diseases.

1. Reducing the activity of immune cells: Sleep is important for the development and functioning of immune cells, such as T cells and natural killers (NK cells), which fight infections and cancer cells. The lack of sleep reduces the activity of these cells, weakening the body’s protection.

2. Increase in the level of inflammation: The lack of sleep helps to increase the level of inflammatory cytokines in the blood, which can lead to chronic inflammation and increase the risk of developing cardiovascular diseases, diabetes and other diseases.

3. Increase in the risk of infections: Studies have shown that people who sleep less than 6 hours a day have an increased risk of infection of colds, influenza and other infectious diseases.

B. Cardiovascular system: increased load

The lack of sleep has a negative effect on the cardiovascular system, increasing the risk of developing hypertension, heart failure, stroke and other diseases.

1. Improving blood pressure: The lack of sleep can lead to an increase in blood pressure, both in the daytime and at night. Chronically increased blood pressure increases the load on the heart and blood vessels, increasing the risk of developing cardiovascular diseases.

2. Cardiac violation: The lack of sleep can violate the heart rhythm, increasing the risk of arrhythmias, such as atrial fibrillation.

3. Improving cholesterol levels: The lack of sleep can help increase the level of “poor” cholesterol (LDL) and reduce the level of “good” cholesterol (HDL), which increases the risk of atherosclerosis and cardiovascular diseases.

C. Endocrine system: hormonal imbalance

The lack of sleep has a significant effect on the endocrine system, violating the production of various hormones, such as insulin, cortisol and growth hormones.

1. Insulin resistance and diabetes: The lack of sleep reduces the body’s sensitivity to insulin, which can lead to the development of insulin resistance and increase the risk of type 2 diabetes.

2. Increasing the level of cortisol: The lack of sleep helps to increase the level of cortisol, stress hormone. Chronically increased level of cortisol can lead to various negative consequences, such as a decrease in immunity, increasing blood pressure and weight gain.

3. Reducing the level of hormone growth: During deep sleep, growth hormone is developing, which plays an important role in restoring tissues, muscle growth and metabolic regulation. The lack of sleep can lead to a decrease in the level of growth hormone, which can negatively affect these processes.

D. Metabolism: metabolic disorder

The lack of sleep violates metabolism, contributing to the weight gain, the development of obesity and metabolic syndrome.

1. Strengthening the feeling of hunger and decrease in a sense of saturation: The lack of sleep affects hormones that regulate appetite, increasing the level of ghrelin (hormone hormone) and reducing the level of leptin (saturation hormone). This can lead to overeating and weight gain.

2. Reducing the speed of metabolism: The lack of sleep can reduce metabolism, which complicates the burning of calories and helps to accumulate fat.

3. Increased traction to unhealthy foods: The lack of sleep can increase the craving for unhealthy foods, such as sweets and fatty foods.
