What good sleep promises for the future

It is said that if a Japanese man lives for 81 years, he will spend 25 years and one day of that time sleeping, and if a Japanese woman lives for 1 years, she will spend 87 years and 26 days of that time sleeping. In other words, we spend about one third of our lives sleeping.

Lack of sleep can cause physical and mental disorders such as general fatigue, weakened immunity, irritability, and anxiety, and can lead to lifestyle-related diseases such as high blood pressure, diabetes, and hyperlipidemia, as well as mental disorders such as depression. It has also been shown that insomnia has a negative impact on social life in general, reducing the ability to enjoy relationships with others and the ability to complete work. Furthermore, it has been pointed out that the quality of life (QOL) of patients with severe insomnia is as poor as or worse than that of patients with heart failure.

Sleep has long been considered unproductive, but science has proven the opposite: quality sleep promises better mental and physical health, improved beauty, and better daytime performance.

Here are three ways that good sleep can promise a better future.

1. The power of sleep to protect the mind and body

According to a large-scale survey conducted in the United States, people who sleep 6.5 to 7.4 hours have the lowest mortality rate, and those who sleep less or more than that have a higher mortality rate. Also, an epidemiological survey of 24,686 people in Japan revealed that people who get 7 to 8 hours of sleep have the lowest depression levels, so good quality sleep is essential for maintaining physical and mental health.

2. The power of sleep to improve your beauty

A 2013 study in Sweden found that women who don't get enough sleep have droopy eyelids, bloodshot, puffy eyes, and noticeable dark circles under their eyes. They also report paler skin, more noticeable wrinkles and fine lines, and a droopy mouth. Adequate sleep has been shown to help maintain a healthy appetite center and help maintain a healthy figure.

3. The power of sleep to maximize productivity

An experiment was conducted to compare the wakefulness of 20 doctors who worked night shifts and those who did not. In an experiment in which the doctor had to press a button 90 times when a figure appeared on the screen, the doctors who had just finished the night shift responded slower than the doctors who did not work night shifts, and sometimes did not respond for nearly four seconds even though the figure was on the screen. This is a clear experimental result that shows that lack of sleep leads to a decrease in concentration, attention, and memory.

By ensuring sufficient time and quality sleep every day and correctly understanding the power of sleep, you can attract a brighter future.
