With age, the mechanism of thermoregulation is altered, causing a decrease in the sensation of thirst, so that older people are more likely to suffer from dehydration. The most serious, in this context, heat stroke, which occurs when the body's thermoregulatory mechanisms are overwhelmed by excessive exposure to a warm climate, coupled with inadequate fluid intake and increased losses.

Older people should drink 6-8 glasses of fluids daily (water, juices, milk, tea and soft drinks) and eat certain foods with high water content like fruits and vegetables (melon, watermelon, strawberry, grapefruit, grape, orange, cucumber, etc).

This group should drink fluids gradually, increased in the morning and afternoon, to decrease the frequency of wetting. The temperature should be between 11 º C and 14 º C. It is advisable to drink 1-2 glasses of water on rising, and that can help the bowel.
