Living and Wellness Effects of Humidity on Your Body By Urgent Care, June 23, 2014 Hot, humid summer days can feel unbearable sometimes. Humidity, or the amount of moisture in the air, can make the temperature feel warmer, as our sweat is slower to evaporate. Not only is the muggy air uncomfortable, but it can cause our bodies to overheat, exhaust easily, and poses a potential danger to our health. Your Body’s Response to High Humidity To understand the effects humidity has on our bodies, we must first take a look at how we regulate our internal temperature. Naturally, when our bodies start to heat up, we release sweat. This sweat is then evaporated from the skin, which in turn, helps to cool us off. When the air has a high moisture content, as is the case in humid weather, this sweat cannot evaporate, leaving our bodies feeling hot and sticky. To cool off, our bodies must work even harder. This results in excessive sweating, increased rate and depth of blood circulation and increased respiration. Excessive sweating can cause a loss of water and chemicals that the body needs in order to function properly, potentially putting our health in jeopardy.

Because the air feels warmer than the official, recorded temperature, it can contribute to feelings of low energy and lethargy. In addition, hyperthermia, or over-heating as a result of your body’s inability to effectively let out heat, can negatively impact your health in conditions of high humidity. Some health risks which result from overexposure to humidity (hyperthermia) include: Dehydration Fatigue Muscle cramps Heat exhaustion Fainting Heat stroke If you or someone you are with begins to exhibit symptoms of heatstroke, such as headaches, confusion, or vomiting, seek medical attention immediately.
