Information on TV Broadcast “Horan × Sassy no Jinsei Tokusuru!? Hihihi na Hijoshiki”(Nippon TV network)

We are pleased to inform you that Dr. Masashi Yanagisawa, Director of the International Institute for Integrative Sleep Medicine (WPI-IIIS), University of Tsukuba, will appear on “Horan × Sassy no Jinsei Tokusuru!? Hihihi na Hijoshiki,” a television program broadcast on the Nippon TV network and produced by Chukyo TV.

In this segment, Dr. Yanagisawa challenges the common belief that “using a smartphone before bed is bad for sleep.” Drawing on the latest findings in sleep science, he explains what really matters for achieving good-quality sleep.

The program features an experiment using “InSomnograf,” EEG sleep monitoring service, to investigate whether smartphone use before bedtime truly affects sleep quality. By comparing brainwave data from nights with and without smartphone use, the program clearly illustrates the differences in sleep patterns.

The details follow below. Don’t miss it!
(*Please note that it may be postponed or canceled in the event of breaking news or other urgent updates.)
（＊The program is also scheduled to be available for on-demand viewing on TVer after the broadcast. We encourage you to watch it.）
