One of the causes is "disorder of the autonomic nervous system" In modern life, the sympathetic nervous system remains dominant even at night, making the autonomic nervous system prone to disorder. In addition, April is the month when new lives begin, such as moving to a new grade, starting a new job, or moving, and unknowingly the mind and body become tense. Then, from the end of April to the start of the long holiday in May, this tension is broken, our daily rhythms are disrupted, our minds and bodies are not in order, and various ailments appear. This is what is known as "May Sickness." One of the major causes of May Sickness is thought to be "disorders of the autonomic nervous system . " There are no national holidays in June, and it is also the rainy season, so it is a time when feelings become negative and the autonomic nervous system is easily disturbed due to changes in atmospheric pressure, which can lead to June Sickness. Some people suffer from insomnia due to autonomic nervous system disorders, but for others, autonomic nervous system disorders are caused by poor quality sleep. This year, the temperature changes are particularly likely to disrupt the autonomic nervous system! This year, compared to last year, there were many days when the difference between the maximum temperature and the day before was large, and the average difference in maximum temperature from the day before over the 10 days from 4/27 to 5/6 during Golden Week was 2.47°C, about twice as much as last year's 1.24°C. Temperature differences also have a significant effect on the autonomic nervous system, so this year is a year in which the autonomic nervous system is more likely to be disturbed than in previous years. The temperature difference during Golden Week makes it easier to become disturbed, but in the coming week, it is forecast that temperatures will rise and fall by up to 4 °C over the course of several days , and severe temperature differences will continue in the future. Many people who suffer from May blues lose motivation, feeling like they don't want to go to work or don't feel motivated. The temperature changes in May can cause the autonomic nervous system to become unregulated, leading to June sickness. A survey conducted by Brain Sleep revealed the impact that sleep quality has on motivation, demonstrating that improving the quality of your sleep is important in order to avoid May blues. People who feel sad about going to work more often have poorer quality sleep 35% of the low-quality sleep group, ranked D, felt sad about going to work more than five days a week, which was 3.8 times higher than the high-quality sleep group, ranked A. Furthermore, 70% of the high-quality sleep group, ranked A, felt sad about going to work 0 days a week. Better sleep means better motivation When asked about how often they felt like it was a hassle to do anything, 59% of people in the A-ranked group, who had high sleep quality, answered "almost never," compared to just 15% of people in the D-ranked group, who had low sleep quality - a difference of about four times. People who work long hours of overtime have poor quality sleep It has also been found that there is a correlation between sleep quality and overtime hours. In the low sleep quality D rank group, the percentage of people who worked less than 0 hours of overtime was 39%, while in the high sleep quality A rank group, the percentage was 66%. Furthermore, if the overtime hours are long, the sleep time will also be short, which may further worsen the sleep situation. Brain Sleep Proposal ! "Golden 90 minutes" to improve your quality of sleep Brain Sleep calls the first 90 minutes of sleep, when you can get the deepest non-REM sleep, the "golden 90 minutes." During these 90 minutes, five physiological phenomena important to sleep, such as "resting the brain and body," "organizing and consolidating memories," "adjusting hormone balance," "boosting immunity," and "removing waste products from the brain," are particularly active. When it comes to getting sleep, it's not just the duration that's important, but also the quality. For Japanese people, who tend not to get enough sleep, getting a deeper, longer first 90 minutes of sleep will improve the quality of their sleep.
