Why We Sleep by Matthew Walker explores the crucial role of sleep in overall health. It reveals how sleep deprivation impacts physical and mental well-being, emphasizing the need for sufficient rest
The book Why We Sleep is one of the significant foreign books that serves as an important scientific source in the field of mental health. The book, authored by Matthew Walker, discusses the importance of sleep in human life and how losing an hour of your day affects your physical and mental health. A person needs about 7 hours of sufficient sleep, but research conducted by the author found that about two-thirds of people in industrial countries only achieve 6 hoursد of sleep. In the United States, around 65% of adults get only 9 hours of sleep. After presenting more statistics, the author in Why We Sleep Matthew Walker decided to discuss physical health issues before psychological ones and the negative effects on individuals who experience prolonged wakefulness without sleep. He mentioned in the Why We Sleep summary that some of the problems individuals face include heart disease, obesity, diabetes, and many serious psychological symptoms that can lead to deteriorating physical and mental health, ultimately affecting various aspects of life.
The book Why Do We Sleep narrates the story of short sleepers—those who sleep less than 7 hours daily. These individuals often believe that 5 hours is sufficient for good health and interaction in their work environment. However, it's essential to recognize the damages incurred from reduced sleep (exposure to phone and screen light for longer than usual, increased caffeine intake, some consuming alcohol to stay awake, and exposure to artificial light).
Why Do We Sleep book begins to explain the effects we experience throughout the day, which include:
- Artificial Light: Did you know that artificial light can convince the brain that it is natural sunlight, making you feel like you're always exposed to the sun? This delays the release of melatonin, causing insomnia. For example, if you are exposed to light from a lamp at 200 lux, this can delay melatonin release by up to 50%.
- Home Temperature: Many people mistakenly believe they need to feel warm to sleep. However, scientifically, your temperature should drop by at least two degrees for a naturally restful sleep.
- Alcohol: Alcohol is considered a depressant for REM sleep, but it does not promote healthy sleep; rather, it disrupts it. One of the lesser-known effects of alcohol is memory loss, which can be as much as 50% of the previous night's memories.
- Caffeine: This important element discussed in Why We Sleep fills the brain's adenosine receptors with caffeine, delaying the feeling of sleep.
