A body cooler that can be used not only to cool the neck but also to cool other parts of the body and has high cooling efficiency is provided. We also provide body warmers that can achieve high warmth. A body cooling device includes a cooling member (10) having an elongated shape and having a water absorbing material (11), and an elastic member (20) provided at an end of the cooling member (10). . When wound around a predetermined part of the body, the cooling member (10) is pressed against the predetermined part of the body by the elastic force of the elastic member (20), and the cooling efficiency is increased by increasing the density of the water-absorbing material.【課題】首回りだけでなく、身体の他の箇所を冷却するために用いることができ、かつ、その冷却効率の高い身体用冷却具を提供する。高い保温性を実現することができる身体用保温具も提供する。【解決手段】身体用冷却具は、細長形状からなり吸水性材料（１１）を有する冷却部材（１０）と、冷却部材（１０）の端部に設けられた弾性部材（２０）と、を備える。身体の所定の箇所に巻き付けた際に、弾性部材（２０）の弾性力により冷却部材（１０）が当該身体の所定の箇所に押し付けられ、吸水性材料の密度を上げることで冷却効率を高める。
