PROBLEM TO BE SOLVED: To provide hydrogen water for fatigue recovery with hydrogen as an active ingredient having an anti-fatigue effect such as improvements in the autonomic nerve function and the motivation to work, and a fatigue recovery method.SOLUTION: Hydrogen water which is put into a vessel from which hydrogen cannot easily be released is high concentration hydrogen water with a dissolved hydrogen concentration on the day of putting same in the vessel of 0.8 ppm or more and the concentration is maintained at 0.8 ppm or more after 120 days. The vessel which stores the hydrogen water with a dissolved concentration of 0.8 ppm on the day the same is put in the vessel in an aluminum region of a storage part thereof, is a vessel which maintains the concentration of the hydrogen water at 0.8 ppm or more after 120 days of being put in the vessel and the hydrogen in the hydrogen water cannot easily be released from the storage part of the vessel. The hydrogen water for fatigue recovery with hydrogen as an active ingredient is constituted to cause a person to recover from fatigue by drinking 250 ml to 350 ml of the hydrogen water per time dispensed from the vessel, at least once a day.SELECTED DRAWING: Figure 80【課題】自律神経機能の改善、作業意欲向上など、抗疲労効果を有する水素を有効成分とする疲労回復用水素水及び疲労回復方法の提供。【解決手段】水素が抜けにくい容器に入れられた水素水は、溶存水素濃度が、容器に入れた日においては、0.8ｐｐｍ以上であって、１２０日経過後においても0.8ｐｐｍ以上の濃度を維持されている高濃度水素水。前記容器は、容器の収容部のアルミニウム領域に収容された水素水の溶存水素濃度が、容器に入れた日においては、0.8ｐｐｍ以上であって、容器に入れた日から１２０日経過後においても0.8ｐｐｍ以上の濃度を維持されるように、水素水に含まれる水素が前記容器の収容部から抜け出にくい容器である。水素水を容器から注出して、１回２５０ｍｌ乃至３５０ｍｌを１日少なくとも１回以上飲むことにより、ヒトの疲労を回復させるように構成された、水素を有効成分とする疲労回復用水素水。【選択図】図８０
