Researchers from the University of Tsukuba in Japan conducted a comprehensive study involving 100 adults aged 3059 years by employing electroencephalogram (EEG) measurements to assess sleep quality for five nights at the participants' homes. Electroencephalography is a method to record an electrogram of the spontaneous electrical activity of the brain. Additionally, detailed health examinations were conducted at a health care facility in Tokyo.
