Sleep and recovery: an important health factor

Sleep and recovery: an important health factor

1. Introduction: underestimated restoration force

In the modern world, obsessed with productivity and constant activity, the importance of sleep and recovery is often overlooked. We strive to squeeze the maximum from each hour, forgetting that it is at rest that the body is restored, strengthened and prepared for new challenges. Sleep is not just a loss of time; This is a fundamental process necessary for physical, mental and emotional well -being. The lack of sleep, both chronic and acute, can lead to a number of negative consequences affecting all aspects of our lives.

2. Physiology of sleep: Stage Journey

Sleep is not just a state of inaction; This is a complex, cyclic process, including several different stages, each of which plays a role in restoring the body. The sleep cycle consists of two main phases: quick sleep (REM-SN) and slow sleep (NREM-SOS).

2.1. NREM-SOS (slow sleep): Deep recovery

NREM-SN is divided into three stages: N1, N2 and N3.

  • N1 (falling asleep): The transition from wakefulness to sleep. The muscles relax, the pulse slows down, and the body temperature is slightly reduced. It is easy to wake up at this stage. It lasts only a few minutes.

  • N2 (light sleep): Relaxation continues, heartbeat and breathing become more regular. At this stage, “sleepy spindles” and K-complexes occur, which play a role in the consolidation of memory and protection from external stimuli. Most of the night sleep falls on this stage.

  • N3 (deep sleep): The most restored stage of sleep. Breathing becomes deep and slow, blood pressure falls, and the muscles are as relaxed as possible. At this time, the body emits growth hormone, which is necessary to restore tissues, muscle growth and strengthen the immune system. Awakening at this stage can cause disorientation and inhibition.

2.2. REM-SN (quick sleep): processing information and emotions

REM-SOS is characterized by rapid eye movements, increased brain activity, similar to activity in a state of wakefulness, and muscle paralysis (which prevents the physical playing of dreams). REM-SN plays an important role in the consolidation of memory, training, processing emotions and mood regulation. It is at this stage that we see the most vivid and memorable dreams.

2.3. Sleep cycles: repeating model

One sleep cycle, including all the stages of NREM and REM-SNA, lasts approximately 90-120 minutes. During the night we pass through 4-6 such cycles. As it approaches in the morning, the duration of the stages of deep sleep (N3) decreases, and the duration of REM-SNA increases.

3. The influence of sleep on physical health

The lack of sleep has a deep effect on all systems of the body, increasing the risk of developing various diseases.

3.1. Immune system: protection against infections

During sleep, the immune system produces cytokines – proteins that help fight inflammation and infections. The lack of sleep reduces the production of cytokines, making the body more vulnerable to diseases. Chronic lack of sleep is associated with an increased risk of infection of colds, influenza and other infectious diseases. In addition, it can worsen the course of chronic diseases such as autoimmune disorders.

3.2. Cardiovascular system: Heart and Vascular Health

The lack of sleep increases blood pressure, increases cholesterol and contributes to the development of inflammation in the vessels. These factors increase the risk of developing cardiovascular diseases, such as coronary heart disease, stroke and heart failure. Dream plays an important role in the regulation of hormones that affect blood pressure and heart rate.

3.3. Metabolism and weight: regulation of appetite and energy

The lack of sleep violates the regulation of hormones that control appetite and metabolism. It reduces the level of leptin (hormone suppressing appetite) and increases the level of ghrelin (hormone stimulating appetite). This leads to an increase in the feeling of hunger, especially to the craving for sweet and fatty foods, which contributes to weight gain and the development of obesity. In addition, lack of sleep reduces insulin sensitivity, which increases the risk of type 2 diabetes.

3.4. Endocrine system: hormone balance

Dream plays a key role in the regulation of the production of various hormones, including growth hormone, cortisol (stress hormone) and melatonin (sleep hormone). The lack of sleep can lead to the imbalance of these hormones, which can negatively affect growth, development, reaction to stress and circadian rhythms. For example, chronic lack of sleep can lead to an increase in the level of cortisol, which contributes to the development of anxiety, depression and other mental disorders.

3.5. Muscle system: Restoration and growth

During sleep, the recovery and growth of muscle tissue occurs. The growth hormone distinguished during deep sleep plays an important role in restoration of muscles after training and physical exertion. The lack of sleep slows down muscle restoration, increases the risk of injuries and reduces the effectiveness of training.

4. The influence of sleep on mental health

Dream has a huge impact on cognitive functions, emotional regulation and general mental well -being.

4.1. Cognitive functions: memory, attention and training

Dream plays an important role in the consolidation of memory, that is, in the process of transferring information from short -term memory to long -term. The lack of sleep worsens memory, attention, concentration and the ability to learn. It also reduces the reaction rate and increases the risk of errors. Chronic lack of sleep can lead to a decrease in cognitive functions comparable to the effect of alcohol intoxication.

4.2. Emotional regulation: mood and stability

Sleep is necessary for processing emotions and regulation of mood. The lack of sleep can lead to increased irritability, anxiety, depression and emotional instability. He can also worsen the ability to cope with stress and negative emotions. REM-SN, in particular, plays an important role in processing emotional experiences and reducing their intensity.

4.3. Mental disorders: risk and exacerbation

The lack of sleep is a risk factor for the development of various mental disorders, such as depression, anxiety disorders, bipolar disorders and a deficiency of attention and hyperactivity (ADHD). He can also worsen the current of existing mental disorders. Many psychiatric drugs can affect sleep, so it is important to discuss problems with sleep with a doctor.

5. Factors affecting the quality of sleep

Many factors can affect the quality and duration of sleep.

5.1. Circus rhythms: inner clock

Circat rhythms are internal biological watches that regulate the sleep-bonding cycle. They are synchronized with external signals, such as light and darkness. Violation of circadian rhythms, for example, with replaceable work or at the intersection of time zones (jetlag), can lead to insomnia and other sleep problems.

5.2. Light: Melatonin regulator

Light plays a key role in the regulation of circadian rhythms and the production of melatonin – a hormone that promotes sleep. Bright light, especially blue light radiated by the screens of electronic devices, inhibits the production of melatonin, making it difficult to fall asleep.

5.3. Temperature: optimal conditions

The body temperature naturally decreases before bedtime. Maintaining cool temperature in the bedroom (about 18-20 degrees Celsius) contributes to falling asleep and improves sleep quality.

5.4. Noise: sleep disturbance

Noise can break the dream, especially at the stages of easy sleep. The use of Birusha or a white noise generator can help disguise unwanted sounds and improve sleep quality.

5.5. Diet: Dream influence

Some products and drinks can affect sleep. Caffeine and alcohol can make it difficult to fall asleep and break the dream. The heavy food, consumed before bedtime, can cause discomfort and worsen the quality of sleep. Eating food rich in triple (for example, turkey, milk, bananas) can contribute to the production of melatonin and improve sleep.

5.6. Physical activity: balance and time

Regular physical activity can improve sleep, but intense training before going to bed may make sleep. It is best to play sports in the morning or early evening.

5.7. Stress and anxiety: psychological factors

Stress and anxiety can significantly worsen sleep. Relaxation practices, such as meditation, yoga and deep breath, can help reduce stress and improve sleep.

5.8. Medical states: impact on sleep

Some medical conditions, such as apnea in a dream, restless legs syndrome, chronic pain and hormonal disorders, can affect sleep. It is important to consult a doctor if you have suspicions of these conditions.

5.9. Medicines: side effects

Some drugs can cause side effects that affect sleep. It is important to discuss with your doctor the possible side effects of the drugs that you take.

6. Sleep hygiene: creating optimal conditions

Sleep hygiene is a set of practices and habits aimed at improving the quality and duration of sleep.

6.1. Regular sleep mode: constancy – the key to success

Try to go to bed and wake up at the same time every day, even on weekends. This will help stabilize circadian rhythms and improve sleep.

6.2. Relaxing ritual before bedtime: preparation for rest

Create a relaxing ritual before bedtime to prepare the body for rest. This may include a warm bath, reading a book, listening to calm music or meditation.

6.3. Comfortable sleeping: silence, darkness and coolness

Provide the quiet, dark and cool atmosphere in the bedroom. Use dense curtains, bears or white noise generator to block unwanted sounds and light.

6.4. Avoid screens before bedtime: blocked blue light

Avoid using electronic devices such as phones, tablets and computers, before bedtime. The blue light emitted by these devices suppresses the production of melatonin and complicates the falling asleep. If you still use electronic devices before bedtime, use blue light filters or glasses that block blue light.

6.5. Limit the use of caffeine and alcohol: impact on sleep

Limit the use of caffeine and alcohol, especially in the afternoon and evening. Caffeine is a stimulator that can make it difficult to fall asleep and break the dream. Alcohol can help fall asleep, but it violates the dream in the second half of the night.

6.6. Avoid heavy food before bedtime: discomfort and sleep disturbance

Avoid eating heavy foods before bedtime. Heavy food can cause discomfort and worsen the quality of sleep.

6.7. Regular physical activity: moderation and time

Regular physical activity can improve sleep, but avoid intense training before bedtime.

6.8. Convenient mattress and pillow: comfort and support

Invest in a convenient mattress and pillow, which provide sufficient support and comfort.

6.9. Use the bedroom only for sleeping and sex: Association with a vacation

Use the bedroom only for sleep and sex. Avoid work, watching TV or food in the bedroom so that your brain associates the bedroom with rest and sleep.

6.10. Wake up from natural light: regulation of circadian rhythms

If possible, wake up from natural light. Natural light helps regulate circus rhythms and improves mood.

7. Sleep disorders: diagnosis and treatment

If you have serious sleep problems, it is important to consult a doctor for diagnosis and treatment.

7.1. Insomnia: Difficulties with falling asleep and maintaining sleep

Insomnia is a common sleep disorder characterized by difficulties with falling asleep, maintaining sleep or a sense of lack of sleep. Insomnia can be acute (short -term) or chronic (prolonged). The treatment of insomnia may include cognitive-behavioral therapy for insomnia (KPT), medicines or a combination of both methods.

7.2. Apnee in a dream: breathing stops during sleep

Apnee in a dream is a serious sleep disorder characterized by breathing stops during sleep. In a dream, apnea can lead to snoring, fatigue, drowsiness during the day and increased risk of developing cardiovascular diseases. Treatment of apnea in a dream may include the use of a CPAP apparatus (a constant positive pressure in the respiratory tract), surgical intervention or a change in lifestyle.

7.3. Restless legs syndrome: an irresistible desire to move your feet

Restless legs syndrome (SBN) is a neurological disorder characterized by an insurmountable desire to move legs, especially at rest. SBN can disrupt sleep and worsen the quality of life. Treatment of SBN can include medicines, a change in lifestyle and additives.

7.4. Narcopticism: Excessive drowsiness in the daytime

Narcolemic is a neurological disorder characterized by excessive drowsiness in the daytime, cataplexia (sudden loss of muscle tone), sleepy paralysis and hypnagogical hallucinations (bright dreams that occur during falling asleep or awakening). Treatment of narcolepsy may include medicines and a change in lifestyle.

7.5. Parasia: Unusual behavior during sleep

Parasunia is a group of sleep disorders characterized by unusual behavior during sleep, such as salting, lunatism, nightmares and night enuresis. Treatment of paracinon can include medicines, psychotherapy and a change in lifestyle.

8. Tools and technology for sleep monitoring

There are many tools and technologies that can help track and analyze sleep.

8.1. Fitness trackers and smart watches: Sleep tracking
