HOT TAB, certified as a Kanagawa Prefecture "ME-BYO BRAND," launches a joint spring self-care campaign with Doctor Air

Hot Tab Carbonated Spring Tablet Co., Ltd.'s "HOT TAB," a brand certified as a Kanagawa Prefecture "ME-BYO BRAND," will launch a joint campaign with Dream Factory Co., Ltd.'s total body care brand "Doctor Air," focusing on spring self-care habits. Spring is considered a time when people easily feel changes in their physical condition due to seasonal shifts, such as autonomic nervous system imbalances and poor circulation. This project proposes self-care habits that are easy to incorporate during such times. This initiative is a joint project centered on sales promotions and social media campaigns.

Background of the Joint Project: Offering the "warming" option of bicarbonate for spring's "fluctuations"

Spring is a season when the autonomic nervous system is easily disrupted due to temperature differences and environmental changes, making it easy to lose physical and mental balance. "HOT TAB," the inventor of bicarbonate bath tablets, uses its unique patented manufacturing technology to efficiently dissolve bicarbonate ions by keeping the bath water neutral, achieving a high warming bath effect.

In this campaign, we will widely propose a "circulation care habit" that combines "daytime conditioning" through Doctor Air's body care with "nighttime warming" through HOT TAB, promoting blood circulation and deep relaxation.

Spring Circulation Care Campaign

This campaign proposes a spring self-care habit of "conditioning during the day and warming at night," combining the bathing habit of HOT TAB's bicarbonate bath with the body care habits proposed by Doctor Air.

Furthermore, in the "Awareness Survey on Spring Fluctuations" conducted prior to the campaign launch, approximately 70% of respondents reported feeling changes in their physical and mental condition in spring, once again highlighting the importance of self-care during seasonal transitions.
