Sleep plays a vital role in our lives, affecting our overall physical and mental well-being. This is a time of recovery and rest for the body. In this article, we will look at the impact of sleep on various aspects of our lives, methods for improving sleep quality, and practical recommendations for making sleep truly the key to good health.
Physiology of sleep
Did you know that on average a person wakes up 3 to 4 times a night? These awakenings can be brief and are often associated with natural sleep cycles, turning over, or changes in body position. Usually we don’t notice this and immediately go back to sleep.
Sleep consists of several phases, each of which performs specific functions to restore the body:
1. Rapid eye movement sleep (REM sleep). In this phase, the processes of restoring mental energy, processing information and dreams occur.
- Characterized by Rapid Eye Movements.
- In this phase, dreams occur, accompanied by vivid dreams.
- The stage at which memory recovery and consolidation occurs.
2. Non-REM sleep (NREM sleep). In this phase, physical energy is restored, tissue growth and repair occur.
The human biological clock works in such a way that the deepest and most restorative sleep occurs in the first half of the night. Therefore, going to bed before midnight can be beneficial for your sleep quality.
During sleep, memory consolidation and information processing occur. Breathing becomes more regular and slower than when you are awake. The heart rate slows down, which helps restore the cardiovascular system and lower blood pressure. Sleep plays a key role in maintaining a healthy immune system, strengthening the body’s defenses.
The importance of sleep for the body
Sleep is an integral part of the life cycle of humans and other living beings. During sleep, the body restores physical and mental energy, cell growth and repair processes occur. Lack of sleep can lead to serious health consequences
Suffers from the physical side:
Cardiovascular Health. Lack of sleep is associated with an increased risk of developing cardiovascular diseases such as hypertension (high blood pressure), heart attacks and strokes. Insufficient sleep can impair heart and vascular function and increase levels of stress and inflammation in the body.
Metabolism and Weight. Lack of sleep can lead to metabolic disorders and insulin resistance, which contributes to the development of obesity and type 2 diabetes. Insufficient sleep increases levels of the hormone ghrelin (the hunger hormone), which can lead to excessive appetite and improper nutrition.
Immune System. Sleep plays a key role in maintaining the body’s immune function. Lack of sleep reduces the activity of natural killers and other cells of the immune system, making a person more vulnerable to infections and viruses.
Muscles and Recovery. Sleep is essential for muscle recovery and growth, as well as for the repair of body tissues and cells after exercise and injury. Lack of sleep can slow down the recovery process, increasing recovery time from injury and fatigue.
Skin Health. The quality of your sleep directly affects your skin health. Lack of sleep can lead to dark circles under the eyes, puffiness, and poor overall skin condition.
Mental health also suffers:
Stress and emotional state. Lack of sleep increases stress levels, making a person less able to effectively cope with everyday challenges and stressful situations. A tired body has a higher reaction to stressors and has a harder time recovering from them.
Depression and anxiety disorders. Lack of sleep is associated with an increased risk of developing depression and anxiety disorders. Not getting enough sleep affects your brain chemistry, worsening your mood and increasing your anxiety.
Cognitive functions and memory. Sleep plays an important role in learning, memory and concentration. Lack of sleep can lead to decreased cognitive function, impaired decision-making and memory retention.
Risk of psychiatric diseases. Long-term sleep deprivation can increase the risk of developing more serious psychiatric conditions such as bipolar disorder or schizophrenia.
Emotional regulation. Lack of sleep can reduce your ability to control your emotions and respond appropriately to stressful situations. People with insufficient sleep often experience increased irritability and an inability to effectively manage their emotions.
