Abstract
Cold exposure, especially in combination with physical activity, are common hardening procedures. However, the effects of such procedures in old age have been little studied. This study, conducted using the homeostasis stability coefficient indicator, provides for the first time comprehensive information on the body response of old and young Wistar rats to a 20-minute swim in cold water. The effects of hormonal, hematological and morphofunctional systems have been studied. Unfavorable age-related changes in the stability of homeostasis were discovered in old rats, which complicate its recovery after cold stress and require the involvement of a greater number of homeostatic mechanisms compared to young animals. The liver was found to be the most vulnerable organ to cold stress. It is concluded that it is possible to use cold hardening procedures in old age, considering age restrictions.
