Information on Article Publication “Are morning/night types determined by genetics? 5 reasons why we get sleepy in spring and how to get through it” (Mainichi Medical)
Dr. Takeshi Sakurai, Vice Director of WPI-IIIS, University of Tsukuba, has published an article on the medical and health information site “Mainichi Medical”, released on Wednesday, April 8.
In the article, he explains the phenomenon of feeling sleepy in spring. It is not mere laziness, but a physiological response caused by a combination of factors such as changes in daylight, temperature fluctuations, and the mismatch between our biological clocks and social rhythms. He also discusses how “chronotypes” (being a morning or night person) are influenced by genetics, and introduces hints for getting through the season, such as regulating your biological clock with morning light. Please be sure to check it out!
