Can you be allergic to heat?

Let’s start with this – heat, as beauty, is in the eye of the beholder. To some, 25 degrees Celsius is a good enough reason to break out the ole AC – their biggest fan! To others… well, let’s just say Death Valley is inhabited. Yes, it is. People live there and they have no complaints. Ok, it’s not overpopulated or anything but the fact the hottest place in the world is populated has to mean something. Or not. What do you need to travel to Death Valley? Dental records.

Some take the more moderate approach. “It’s finally hot enough to complain that it is too hot.”

So is heat allergy actually a thing?

Not exactly. Most of us find it hard to feel comfortable when it seems like someone bombed the ozone layer. Heat rash is a thing, for instance. This skin condition often affects people in hot, humid weather conditions. It happens when your pores get clogged up and sweat can’t escape.

What causes heat rash? This is often friction on the skin’s surface. Babies develop heat rash mostly on their necks, but it can also occur in the armpits, elbows, and thighs. Adults usually develop it under their arms or between the inner thighs; generally, where body parts rub together.

Heat rashes are relatively common. This is not the same as a heat allergy. Heat intolerance is also a thing. Common causes of heat intolerance – feeling horrible when it’s hot, basically – include anxiety, menopause, hyperthyroidism, Graves’ Disease, MS, thyroid cancer, pituitary cancer, peripheral and autonomic neuropathy. Peripheral neuropathy is the most common of these illnesses.

What is peripheral neuropathy? Basically, your peripheral nervous system connects the body to the nerves from the brain and spinal cord, including the arms, feet, hands, legs, face, mouth and internal organs. When these nerves malfunction, they might send pain signals when there’s nothing wrong or vice versa, which may be due to an injury, a chronic spinal disorder, or an infection. Some people in this situation find warm weather impossible to tolerate.
