Also, heart-rate increases to maintain adequate blood pressure. 

In addition to PPE use, exertion, time of day, and humidity, other factors that can increase your chances of a heat disorder include:

  • Old age
  • Lack of sleep
  • Obesity
  • Previous heatstroke
  • Excessive alcohol ingestion (the previous day which causes dehydration).

Symptoms can include headache, nausea, dizziness, irritability, pain, fatigue, or confusion.

A basic safety rule is if you start to feel uncomfortable or stressed, take a break and rehydrate, preferably in the shade.

Remember that staying calm and cool is better than ending up in the hospital.
