Lack of sleep that appears in your appearance and impression …… dark circles, dullness, sluggishness
Chronic sleep deprivation has been reported to increase the risk of various diseases, but it is the change in appearance that many people realize the negative effects of sleep deprivation.
If you don’t get enough sleep, you’ll notice visible changes, such as dark circles under your eyes and tired eyes. In the case of women, it seems that many people are aware of lack of sleep due to dull skin and poor makeup application. If you are very drowsy, you will only be able to respond vaguely when talking to people, and it will be difficult for you to organize your thoughts. Lack of sleep can make you drowsy and lethargic, and you may not be able to act fluently. Lack of sleep can never be ignored as a cause of “looking older” than your actual age.
Lack of sleep increases spots, wrinkles, dullness, and redness? Relationship between sleep and beauty
In recent years, the term “sleep debt” has been used, and sleep deprivation has been reported to have long-term and serious adverse effects on health. Research on sleep and beauty is also a theme that many companies involved in beauty and health are researching.
As an example, let’s look at some reports.
In a study (*1) conducted by POLA CHEMICAL INDUSTRIES that compared the state of the stratum corneum in the morning on days when people slept more than 8 hours and days when they slept less than 3 hours, The mechanism by which lack of sleep causes rough skin has been reported.
In addition, a survey (*2) of women conducted by a British bedding manufacturer reported an increase in the number of wrinkles and spots, as well as an increase in skin redness, after six hours of sleep.
According to a survey report (* 3) by the Sleep Improvement Committee, many women in their 40s with “hidden insomnia” have multiple skin problems such as skin firmness, dullness, wrinkles, and spots. It has been reported that there is a large difference between
In the verification (*4) of Nishikawa, a bedding manufacturer, it is announced that by preparing a good sleep environment, anti-aging effects such as promotion of growth hormone secretion and reduction of oxidative stress can be expected.
In this way, companies and manufacturers outside the medical field are also conducting various surveys and research on the relationship between sleep and beauty, and we can see that the relationship cannot be ignored.
The guideline for sleep time that does not age is “around 7 hours”
In terms of appearance, it is recommended to get 6 to 8 hours of sleep, that is, around 7 hours of sleep, in order to maintain healthy skin, prevent lifestyle-related diseases and depression, and maintain a youthful appearance.
However, since the optimal sleep time varies greatly from person to person, it is not simply “6 hours should be enough” or “you should sleep for 8 hours”. It’s important to be conscious of getting enough sleep that you feel you need, not just the length of time.
Your skin’s golden time lie
In the past, it was thought that “because a large amount of growth hormone is secreted between 22:00 and 2:00, it is better to sleep during this time”, and it was said that the period between 22:00 and 2:00 is “the golden time for the skin.” there is.
But this is not correct. Growth hormone is secreted in large amounts during deep non-REM sleep, not according to the time of day. Deep non-REM sleep often appears in the first three hours after falling asleep. Growth hormone is also related to skin metabolism, so if you get deep non-REM sleep, it will not be limited to 22:00 to 2:00, and your skin will be in a healthier state.
On the other hand, there are aspects that cannot be said to be completely wrong. There are two types of sleep: non-REM sleep and REM sleep. Deep non-REM sleep occurs most often in the first three hours after falling asleep, but the duration of REM sleep increases as the morning progresses. So, for example, if you go to bed at 4:00 am, both NREM and REM sleep will appear at the same time, resulting in an unbalanced sleep. Also, you generally need 6-8 hours of sleep. Most people have to wake up around 6-8am on weekdays. Considering these things, it can be said that sleeping between 22:00 and 2:00, preferably by midnight, is likely to give you a good and sufficient sleep.
From the age of 40 onwards, get a good night’s sleep to avoid looking old
In terms of health and appearance, going from around 40 to menopause is a turning point in life after that. Make sure you get enough sleep so that poor quality or lack of sleep doesn’t make you look older and negatively impact your long-term health.
