本研究は，河川での水難を想定し，「頸部位浸水」と「胸部位浸水」の2つの異なる条件の違いが体温に及ぼす影響を検証することを目的とした．調査は9月下旬，岐阜県長良川にて実施した．気温は22.0～29.3℃，WBGTは21.3～24.7℃，水温は18.2～20.0℃，水の流速は30.1～56.5㎝毎秒であった．12名の男子大学生が本研究に参加した．衣服はＴシャツとハーフパンツ（いずれも綿100％）とした．体温低下の程度を検証するため，ピル型センサを用いて消化器内温度を測定した．検証の結果，各参加者の頸部位浸水の消化器内温度の平均値は，最高が37.48±0.30℃，最低が36.55±0.45℃であった．胸部位浸水のそれは，最高が37.49±0.29℃，最低が37.02±0.23℃であった．また，活動開始時の温度は，頸部位浸水が37.42±0.33℃，胸部位浸水が37.31±0.28℃であり，統計学的有意差は認められなかった．一方で，活動終了時のそれは，頸部位浸水が36.55±0.45℃，胸部位浸水が37.14±0.39℃であり，統計学的有意差が認められた．

This study is based on the assumption that the river is flooded and the "neck area is flooded" and "the chest area is flooded" and the conditions are different and the condition is violated and the body temperature is not affected and the symptoms are not affected by the condition. The investigation was carried out in late September at the Nagara River in Gifu Prefecture. The water temperature is 22.0～29.3℃, the WBGT is 21.3～24.7℃, the water temperature is 18.2～20.0℃, and the water flow rate is 30.1～56.5㎝ per second. Twelve male college students participated in this study. Clothes are made of はＴシャツとハーフパンツ（いずれもcotton 100%）とした. The degree of hypothermia can be verified by measuring the internal temperature of the digester using a ピル type gastrointestinal tract. According to the results of the test, the average temperature inside the digester of each participant's neck was immersed in water, with the highest temperature being 37.48±0.30℃ and the lowest temperature being 36.55±0.45℃. The chest area was soaked in water, with the highest temperature being 37.49±0.29℃ and the lowest temperature being 37.02±0.23℃.また, the temperature at the start of the activity was 37.42±0.33℃ when the neck was immersed in water, and 37.31±0.28℃ when the chest was immersed in water. The statistically significant difference was recognized. On the one hand, at the end of the activity, the neck area was immersed in water at 36.55±0.45℃, and the chest area was immersed in water at 37.14±0.39℃. There was no statistically significant difference.
