Plain hot water drunk for health; a simple wellness trend of drinking boiled-then-cooled water, especially in the morning.

白湯 (plain hot water) has been promoted as a health practice in both Ayurvedic and traditional East Asian medicine, but it became a massive wellness trend in Japan in the 2020s. Celebrities and influencers credit it with improving digestion, circulation, skin quality, and weight loss. Its appeal lies in its simplicity — anyone can do it, and it costs nothing. 白湯 has become a symbol of the 丁寧な暮らし (mindful living) movement.
