With consecutive days of extreme heat and prolonged tropical nights expected, stuffiness from heat buildup in bedrooms and night sweats are common concerns for many people during summer sleep. GOKUMIN offers bedding, from blankets that touch the skin to pillows for your head and mattress pads for your back, each with cooling and dehumidifying features.
