Is it safe to exercise in the heat, and how can you prevent heat-related illness in Europe?

Exercising in the heat explained: dehydration, heat exhaustion, heat stroke, electrolyte balance, and medical risk factors.

In this episode, we outline how high temperatures affect the body during physical activity and how doctors assess heat-related symptoms under EU medical guidance.

You’ll learn:

• How heat increases heart rate and fluid loss through sweat

• The difference between heat cramps, heat exhaustion, and heat stroke

• Early warning signs: dizziness, nausea, headache, muscle cramps

• Why hydration and electrolyte replacement are essential

• Risk groups, including older adults and people with heart conditions

• When exercise should be avoided during extreme heat alerts

• Red flag symptoms such as confusion, collapse, or very high body temperature

• Situations where medical clearance may be required before intense activity

We explain how doctors assess cardiovascular history, medication use (e.g., diuretics), hydration status, and previous heat intolerance during an online consultation in the EU. Suspected heat stroke requires immediate emergency care.

This episode reflects the clinical standards used by Mobi Doctor, where sports and cardiovascular consultations are reviewed by a registered physician in line with EU medical guidance.
