Home economics and life science
You still don't know what a real sleep is. You know what a true sleep is because you've been studying bedding since 400! A super practical method taught by "long-established manufacturers" and "sleep professionals"! According to a study conducted by Stanford University, people who sleep for less than 4 hours on average are 73 percent more likely to be obese than those who sleep 7 to 9 hours on average. However, people are busy and it is difficult to get enough time to sleep. In this book, I will tell you about sleep that people listen to from a sleep professional's point of view. About sleep, urban legends persist, and many people try to identify themselves incorrectly. Based on the results of scientific demonstrations, I will present only the results of long-established companies multiplied by their experience as sleep instructors.
