What Are Sleep and Rest During Sleep? Expert Insights from a Scientific Perspective
Previously, we mentioned that sleep occupies about one-third of human life. But what exactly is “sleep”? Interestingly, sleep is still described as a complex process that is not yet fully understood. It plays a vital role not only in physical rest but also in maintaining brain and emotional health. Rest during sleep is one of the primary purposes of the sleep process, enabling the body and mind to regenerate, store energy, and carry out repair processes.
In this article, we will discuss what sleep and rest during sleep are, why they are important from a scientific perspective, and what individuals can do to achieve restful sleep
What Is Sleep?
Sleep is an active resting period in which the body’s response to external stimuli decreases, but many vital functions continue in the brain and body. The brain performs the tasks of memory formation and information processing. The body carries out repair processes such as hormone secretion and cell renewal. Muscles relax, and energy is replenished.
What Is Rest During Sleep?
Rest during sleep is not merely about physical inactivity but also physiological and psychological renewal. Sleep occurs in two main cycles:
NREM (Non-Rapid Eye Movement) sleep is the phase during which physical recovery takes place. Muscles relax, heart rate and breathing slow down, cells are repaired, and growth hormones are released.
REM (Rapid Eye Movement) sleep, on the other hand, is the phase of intense brain activity when dreams occur. During this stage, the brain forms memories and organizes information collected throughout the day.
For complete rest to occur, both cycles must be experienced at sufficient depth and duration throughout the sleep process.
The Scientific Importance of Sleep
Scientific studies have shown that sleep deprivation negatively affects both physical and mental health. Classic physical impacts include a weakened immune system, chronic fatigue, energy loss, and an increased risk of heart disease and diabetes. Mental and emotional effects include memory and focus problems, increased risk of stress, depression, and anxiety, as well as reduced creativity and problem-solving abilities. Scientific findings indicate that 7 to 9 hours of quality sleep are essential for a healthy life.
Recommendations for Restorative Sleep
For restorative sleep, improving the sleep environment and paying attention to sleep hygiene are crucial. Choosing the right mattress that supports the body, is orthopedic, and breathable is very important. Another factor is sleep hygiene, which involves sleeping and waking at the same time daily, avoiding electronic devices before bed, and ensuring the room is quiet, cool, and dark. In addition, regular exercise improves the sleep process, while avoiding heavy meals and caffeine late at night is equally significant.
Sleep and rest are indispensable for a healthy life. The right mattress choice, sleep hygiene, and lifestyle habits play a critical role in this process. Scientific evidence highlights that quality sleep is essential for both physical and mental health, significantly improving quality of life.
Remember: “A well-rested mind and body are the foundation for a successful day.”
