New Proposals for Better Sleep in the Era of Extreme Heat: Fighting Against Air Conditioner Costs in Japan's Summer

RX Japan LLC (Headquarters: Chuo-ku, Tokyo, Representative Executive President: Takeshi Tanaka) will hold the 'Sleep Well Goods Fair' (within the '21st Health & Beauty Goods Expo') at Tokyo Big Sight from June 24 (Wed) to 26 (Fri), 2026, for three days.

As electricity and city gas price support continues, 'how to sleep while conserving energy' has become a new challenge.

In recent years, Japan's summer has been said to have entered the 'era of extreme heat,' with 'tropical nights' where the temperature does not drop even at night becoming a common occurrence nationwide. While the government is implementing measures to reduce the burden of electricity and city gas prices, and responses to rising energy prices have become a social issue, among households, the pressing concern of 'I can't sleep without an air conditioner, but I'm also worried about the electricity bill' is spreading.

Against this backdrop, the 'Sleep Well Goods Fair' held within the Health & Beauty Goods Expo will feature the latest products that combine sleep quality and energy conservation under the theme of 'sleep strategies to comfortably get through the era of extreme heat,' including cooling bedding, recovery wear, and supplements.

Sleep is shifting from 'rest' to 'self-investment.' It has become a common issue for companies and society as a whole.

Interest in 'sleep debt,' 'well-being,' and 'healthy life expectancy' is increasing year by year, and 'sleep quality' is now an important social theme that directly connects to health, work, beauty, mental care, and productivity.

In particular, in recent years, in addition to sleep deprivation due to heat waves and tropical nights, changes in work styles and stress in society have led to an increase in people who have concerns such as 'I don't feel refreshed even after sleeping,' 'I wake up several times in the middle of the night,' and 'I can't concentrate during the day.' Sleep is no longer seen as mere 'rest' but as 'self-investment' to improve one's physical and mental condition.

Furthermore, as interest in 'health management' and 'well-being management' by companies grows, sleep is also attracting attention from the perspective of improving employee performance and mental care, and 'how to achieve good sleep' has become a common issue for households, companies, and society as a whole.
