During the rainy season, more than 80% of people are likely to have a “deterioration in the quality of their sleep.” As of the start of the rainy season, 60% are “not getting good quality sleep.” The more sunbathing people do, the higher their sleep satisfaction and happiness. to the result
Is poor quality sleep caused by lack of sunlight? ~Expert: “Adequate sunbathing is a prerequisite for good quality sleep. You should go out every day, even on rainy days.” What is the sunbathing method to get a “good sleep” during the rainy season?~
……
Zeon Co., Ltd. (Location: Chiyoda-ku, Tokyo, President and CEO: Tetsuya Toyoshima) provides the device and app “LNES(R) SL-04” that suggests the “just right” time for sunbathing for a limited time. ) conducted a survey on sunbathing among 993 men and women in their 20s to 60s ahead of the start of this year’s rainy season in the Kanto region.
As a result, more than half of the people feel unwell during the rainy season every year, and one in five people have experienced a decline in the quality of their sleep during the rainy season. Also, before the rainy season begins, less than one in three people feel that they are already getting good quality sleep.
Furthermore, based on the “conditions for getting quality sleep on rainy days” that Dr. Shirakawa, an expert on sleep debt, inferred from research data, at least about 80% of the total cases are due to deviations in biological rhythms during the rainy season. It has been found that changes in hormonal secretion may reduce the quality of sleep.
In this press release, we introduce the “sunbathing method” which is a necessary condition for getting a “good night’s sleep” as well as the surprising effects of sunbathing. Lastly, we would like to introduce the sunbathing navigation device “LNES(R) SL-04”, which is supervised by experts in sleep debt, vitamin D, and algorithms and is a hot topic on the crowdfunding site “Makuake.”

・More than half of people feel unwell during the rainy season. One in five people experience a “deterioration in sleep quality” during the rainy season.
・As of the beginning of the rainy season, less than one in three people said they were getting good quality sleep, and 60% said they were not getting good quality sleep. In particular, men in their 50s and women in their 30s and 40s tend to be unable to get quality sleep. ・Only 25.5% of people benefited from good sleep products. People who are more active in sunbathing tend to get better quality sleep. ・45.1% go out every day on sunny days. On the other hand, only 23.1% of people go out every day on “rainy days.”
・About 70% of respondents answered, “I don’t want to go out as much as I do on a sunny day” and “I don’t want to go out as much on a rainy day.”
・Only less than 20% of people spend an appropriate amount of time sunbathing during the rainy season. More than 80% of people fear that their sleep quality will deteriorate during the rainy season.
In rainy and cloudy weather like the rainy season, the key is to reset your biological rhythm and secrete hormones that lead to a good night’s sleep, and to let sunlight in through your eyes.
-Requirements for getting a good night’s sleep on rainy days- 1. Expose yourself to the sun for 20 to 40 minutes before 9 a.m. 2. Expose yourself to sunlight for 1 to 2 hours throughout the day 3. Go out every day even during the rainy season

Representative of the Sleep Evaluation Research Organization, President of the Japan Sleep Improvement Association, Doctor of Medicine, Dr. Shuichiro Shirakawa (Supervised “LNES(R) SL-04”) He serves as the representative of the Sleep Evaluation Research Institute and contributes widely to society as a sleep science expert. He has conducted research on sleep for many years, with a particular focus on sleep quality and its improvement. He has written many books and papers, and also gives lectures, educating society about the importance of sleep and how to manage it. He is frequently featured on TV, radio, magazines, and other media, offering advice on sleep. ・Books: “How to improve your sleep power Nagaoka Shoten” “Eliminating the sleep debt that shortens your life” Shodensha, etc.

~Comment from Dr. Shuichiro Shirakawa of the Sleep Evaluation Research Institute~
・During the rainy season, lack of sun exposure can disrupt biological rhythms, leading to a decline in sleep quality.
Our health depends on wakefulness and sleep. Good quality sleep can be expected to lead to high performance and regeneration of damaged cells by resting the sympathetic nervous system and increasing growth hormone secretion. In order to expect a good night’s sleep, it is very important to maintain your biological rhythm and what you do when you wake up (exposure to the sun, eat, exercise, etc.) in order to get a deep sleep. The basic biological rhythm has a tendency to deviate by more than 10 minutes a day, and is reset by sensing light on the retina of the eye and being exposed to morning light.
・In order to maintain a healthy biological rhythm and expect a good night’s sleep, sleep for 6.5 to 9 hours and wake up from 6 to 7 a.m. In order for growth hormone to be properly secreted and brain waste products to be removed during sleep, it is important that the biological rhythm is in order and melatonin secretion is activated. To get the most out of your sleep, it is said that you need 6.5 to 9 hours of sleep. Also, 14 to 16 hours after the morning biorhythm reset (melatonin suppression), melatonin begins to be secreted due to the biorhythm. Considering this rhythm and sleep time, it is estimated that if you are exposed to the morning sun between 7:00 and 8:00, you will be more likely to fall asleep between 10:00 and 11:00 pm. If you consciously go to bed at this time, you will get 7 to 8 hours of sleep and will be able to maintain a daily rhythm of waking up at 6 a.m. ・To improve the quality of your sleep, the following conditions are required: 1. 20 to 40 minutes of sunbathing before 9 a.m. 2. 1 to 2 hours of sunbathing throughout the day
Considering the amount of light during the rainy season (cloudy to rainy), it is necessary to spend 20 to 40 minutes in the sun by around 9 a.m. to reset your biological rhythm. Unlike vitamin D production due to ultraviolet rays and sunburn, it is effective even in relatively low light levels, so it is more effective to go outside even on rainy days. Also, if you sunbathe for more than 1 to 2 hours throughout the day, you can expect that melatonin secretion will increase, leading to deeper sleep. To improve the quality of your sleep, first of all, it is essential to sunbathe for at least 10 to 20 minutes before 9 a.m. and to sunbathe for a total of at least 1 to 2 hours in the morning and afternoon. We also recommend light exercise in the afternoon. If your biological rhythm is disrupted, it is likely to cause a jet lag-like state without you noticing, leading to a decline in the quality of your sleep.
・The key points for improving the quality of your sleep are “Make it easier to fall asleep,” “Achieve deep sleep,” and “Get 7 to 9 hours of stable sleep.”
In order to make it easier to sleep, you need to reset your biological rhythm every morning. In addition, in order to achieve deep sleep, it is necessary to increase the amount of melatonin secreted by sunbathing throughout the day, and light exercise is even better. By getting deep sleep, the secretion of growth hormone increases during sleep, which promotes the regeneration of damaged cells in the skin and body. By “getting a solid 7 to 8 hours of stable sleep,” it is expected that waste products from the brain will be removed during sleep and “reducing brain fatigue.” Mainly, when these three points are in place, sleep satisfaction increases, cartilage formation/muscle regeneration and growth due to growth hormone, immunity improvement, cancer risk reduction, and mental care through resting the brain and sympathetic nerves. Contribute.
・Furthermore, reset the main clock of the body clock that governs biological rhythms.
After sunbathing, we recommend that you eat breakfast, which contributes to the subclock of your body’s internal clock. It is also important to “don’t touch your smartphone or computer 30 minutes before bed,” “sleep in a relaxed situation,” and “be careful not to drink too much.” Light and the activation of the sympathetic nervous system, which suppress melatonin secretion, tend to make it difficult to fall asleep, so if you try to finish these activities at least 2 hours before going to bed at night, the quality of your sleep will further improve.
~Summary~ Points for sunbathing during the rainy season
■ Necessary conditions for good sleep
1. Go outside every day even during the rainy season
2. Sunbathing for 20-40 minutes before 9am
3. 1-2 hours of sunbathing throughout the day
