Humidity can be defined as the amount of water vapor in the air. In order to understand humidity, you have to know that all around us, there is water in the air. This is the water vapor surrounding us, which is in the form of a gas. If there is too much or too little humidity in the air, it can be equally dangerous. If the earth were to have no humidity, we would have no clouds, thunder, lightning, rain, or snow.

We can’t live without humidity, in fact, some people use humidifiers to actually make their environment more humid, but it’s important to understand how to deal with it when it gets too much. You should know all of the signs that you should get out of the humidity or to a doctor because a lot of the effects of high humidity can be life-threatening.

Humidity Illness

Being exposed to hot temperatures for a prolonged period of time can cause many heat-related illnesses such as heat cramps, heatstroke, and heat exhaustion. As your body is trying to cool itself, your blood rushes to the surface of the skin, which means that less blood is going to your brain, muscles, and other vital organs. This can have a drastic effect on your mental capacity and physical strength. Any of these symptoms are a sign of heat-related illness:

  • Lethargy
  • Confusion
  • Unconsciousness
  • Dizziness
  • Weakness
  • Cramps
  • Fatigue


Humidity affects hydration

When your body isn’t getting enough fluids, it goes through dehydration. You can tell that you are dehydrated by the color of your urine. If it’s a bright yellow to a dark orange color, you’re dehydrated. The darker it gets, the worse you are. You can also tell by these symptoms:

  • Upset or burning sensation in the stomach
  • Tiredness
  • Decreased energy
  • Dry skin
  • Dry mouth
  • Constipation
  • Dizziness
  • Lack of sweating
  • Low blood pressure
  • Delirious (severe symptom)
  • Unconsciousness (Severe symptom)

So, what does this have to do with humidity? You see, when there isn’t much of a difference between the surface temperature of your skin and the ambient air temperatures, there’s not much your body can do to cool you down. The humidity makes it hard for your body to evaporate sweat because the air is already filled with water vapor. This means that your body is going to keep all of that extra heat built up, raising your core body temperature.

In order for your body to maintain its normal body temperature, it must evaporate the sweat. This is when you need to make sure your body has enough fluids in it to produce sweat. If you don’t, you’re going to overheat, which can lead to heatstroke.
