“When there is already a high level of moisture in the air, it is difficult for the air to absorb the moisture from our skin. This can eventually lead to a loss of body fluid and dehydration. Joint cartilage and the discs in our spine have high water content, and dehydration can decrease the concentration of fluid, agitating any arthritis that may be present. Dehydration in the heat can also cause more serious conditions like heat exhaustion and heatstroke.”
