What are side effects of heat exhaustion?

It’s the heat that makes summer more exciting, but it’s also the same thing that can cause problems. You’re probably wondering why? Simple, heat exhaustion does not discriminate and it happens to even the toughest of us. Here you will learn everything you need to know about this discomforting condition.

What is Heat Exhaustion?

Let’s start with what causes it. Have you ever been outside on a sweltering hot day and felt like your body was melting? That feeling might just be heat exhaustion (not fun at all).

Heat exhaustion occurs when we overexert ourselves in high temperatures leading to overheating our body beyond limits of regulation resulting in a series of side effects.


One way or another we always find out we are suffering from Heat Exhaustion eventually by these symptoms:

Sweating Tons

Sudoriferous glands do their magic as soon as your internal temperature begins reaching its peak capacity. Meaning sweat-drenched clothes will most likely expose those extra layers underneath which never gets aired out.

Temperature Dysregulation Issue

The inability for one’s core temperature to regulate normally could indicate an underlying issue such as having dysautonomia or hypovolemia making things much worse entirely.

Accelerated Heart Rate

Have you ever gotten back up after being seated for long hours only to have instant light-headedness combined with heart palpitations? Yes! That may well mean your heart has increased output so it can try its best against dehydration caused by your sweating profusely.

Nausea And Dizziness

These vile demons come together quite predictably causing great unrest due to drop-in blood pressure hence lack of enough oxygen pushingly goes straight virtual blood rushes in ones head!

It appears pretty irritating right?
