Background for This Summer | Forecast of Above-Average Temperatures Continues

According to the "Weather News Extreme Heat Outlook 2026" released by Weather News on June 23, 2026, temperatures this summer (July-September) are expected to be higher than average nationwide, with the heat peaking between late July and early August due to the influence of "double high-pressure systems" where the Pacific high-pressure system and the Tibetan high-pressure system overlap. 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.

Stock Up on Summer Bedding During Prime Day

1 Cool Fit Pillow | Cools Sleepless Nights to Comfortable Sleep with Cool Gel

A pillow integrating cool-touch gel and low-resilience urethane. Head heat dissipates quickly, and the cooling sensation returns with every turn as heat is released. This model is for those who want both a cool feel and a comfortable fit.

2 Hiyatoron Blanket | One Blanket for "Too Cold/Too Hot" with Air Conditioning

A 2-way reversible cooling blanket designed to address the summer sleep dilemma of "too cold with the air conditioner on, too hot when it's off." The coolness can be selected on either side, and using it with air conditioning allows you to set the temperature 1-2°C higher while still feeling cool.

3 Dehumidifying Reversible Mattress Pad & Pillow Pad | Cooling and Dehumidifying in One

A mattress pad and pillow pad with a 4-layer structure incorporating a silica gel x diatomaceous earth dehumidifying sheet, offering cooling, dehumidifying, breathability, and antibacterial properties. Simply laying it down cares for not only the heat but also night sweats and moisture. The reversible design allows for year-round use, even in seasons other than summer.
