Why should I limit my time in the spa to only 15 to 20 minutes?
People on average sit in spas or hot tubs for about 20 minutes. Much longer than that and your body (you) begins to feel feverish. A study of women ages 18 to 38 published in the Canadian Journal of Medicine found that the core body temperature reaches 102°F after soaking for 40 minutes. For many people, especially children or folks with circulatory conditions, that can be dangerous. Limit your soak time to no more than 15 to 20 minutes.
