An object of the present invention is to cool the back of the neck by a cooling device that can be at any time used in the bathtub, by giving a cold stimulus alternately to many hands of the cold spot to feel the cold, brown fat to convey the information of the cold in the brain the function of the cells were more active of the is to provide a basal metabolism improvement aid for improving the basic metabolism. When [Resolution] bathing, intermittently cooling the back and both hands of the bathers neck warmed by hot water, so that by alternating stimulation of cold is to improve the basal metabolism prompted the activation of brown fat cells, soft chloride and brown adipocytes cooling portion 2 for cooling the back of the neck, filled with refrigerant in a plastic case made, the both right and left sides of the brown adipocyte cooling unit 2 is connected via a flexible sheet member 4, the right and left In the two grip cooling section 3 filled with a cold storage agent Jisuru grip by hand to form a basal metabolism improvement aids 1. .BACKGROUND【課題】浴槽内で随時使用できる冷却具によって首の後ろを冷却するとともに、冷たさを感じる冷点の多い手にも冷温刺激を交互に与えて、冷たいとの情報を脳に伝えて褐色脂肪細胞の働きをより活発化させて基礎代謝の向上を図る基礎代謝向上補助具を提供する。【解決方法】入浴時、温湯で暖められた入浴者の首の後ろと両手を間欠的に冷却し、冷温の交互刺激によって褐色脂肪細胞の活性化を促し基礎代謝を向上させられるよう、軟質塩化ビニール製ケースに保冷剤を充填した首の後ろを冷却する褐色脂肪細胞冷却部2と、前記褐色脂肪細胞冷却部2の左右両側にシート状可撓性部材4を介して接続され、それぞれ左右の手で握持する保冷剤を充填した二つの握持冷却部3とで基礎代謝向上補助具1を形成する。【選択図】図1
