Even if the summer air conditioner feels comfortable, it stimulates the body when sleeping, and sleep is affected by Professor Kazuyo Tsuzuki of Toyohashi University of Technology, National Institute of Advanced Industrial Science and Technology, and housing maker. It was found in a joint research by Asahi Kasei Homes Co., Ltd.

 According to Toyohashi University of Technology, the research team of Professor Tsuzuki and his colleagues used air conditioners with an average wind speed of 0.14 meters per second and 0.04 meters per second, and the depth and body temperature of sleep when sleeping in two rooms with the same temperature setting of 26 degrees. I checked the adjustment and so on.
As a result, the subject felt that the one with a strong wind speed was comfortable when waking up, but when the timing of the airflow and the movement of the body, the heart rate, the depth of sleep, etc. were examined, the one with a strong wind speed had a body movement and a heartbeat. The number increased and the frequency of awakening was high.

 The research team believes that summer air conditioners have some effect on sleep, as general air conditioners turn over at the moment of cold wind and change the depth of sleep.The subjects of the experiment were healthy adolescent men, but older people who were weak and women who were sensitive to the cold could have a greater impact.

 It is not uncommon for urban warming to prevent temperatures from dropping at night and to worsen sleep quality during tropical nights.It is said that if the room temperature is adjusted well with the air conditioner, you can get a good night's sleep, but if you use the air conditioner all night, it is bad for your health.
Since there was no data showing how the strength of the wind speed affects, this research is said to be a useful clue to create a comfortable sleeping environment.
