There is something remarkable about the running community in the UAE. Despite temperatures that can exceed 45 degrees Celsius in summer, people are out on the Corniche, along Dubai Creek, and through community tracks at all hours of the day and night. As a physiotherapist who sees active people in this region, I have a deep appreciation for that dedication, and a deep awareness of the risks that come with it.

How Heat Affects the Body During Exercise

When you exercise in high temperatures and humidity, your body faces a dual challenge: it must deliver oxygen to working muscles while simultaneously diverting blood to the skin to facilitate cooling. This cardiovascular competition reduces performance and accelerates fatigue. Sweating in Dubai's climate can lead to fluid losses of more than one litre per hour, and with that fluid goes electrolytes essential for muscle and nerve function.

The Musculoskeletal Impact of Heat

From a physiotherapy perspective, heat and dehydration have direct effects on the musculoskeletal system. Dehydrated muscle tissue is less pliable and more vulnerable to strain. Connective tissue including tendons and ligaments also becomes more vulnerable when the body is under heat stress. I often see an uptick in calf strains, Achilles tendon problems, and hamstring injuries during the hotter months among outdoor runners in Dubai.

Heat-Related Conditions to Recognise

Understanding the spectrum of heat illness is important for every outdoor athlete in the UAE.

  • Heat cramps: Painful muscle spasms, usually in the legs or abdomen, caused by electrolyte depletion.
  • Heat exhaustion: Heavy sweating, weakness, cold or pale skin, a fast or weak pulse, nausea, and possible fainting. This requires immediate rest, hydration, and cooling.
  • Heat stroke: A medical emergency characterised by a body temperature above 40 degrees Celsius, hot and red skin, rapid or strong pulse, and possible unconsciousness. Call emergency services immediately.
Training in the UAE heat is not just about fitness; it is about understanding your environment and respecting what it demands of your physiology. The athletes who do this well are the ones who stay injury-free year-round.

Practical Strategies for Safe Outdoor Training

Physiotherapy and sports science both provide clear guidance on how to train effectively in extreme heat.

Time Your Training Wisely

In Dubai, outdoor running is best scheduled before 7am or after 8pm during summer months. During Ramadan, many residents adapt their training to the cooler night hours, which is often a sensible approach year-round in peak summer.

Heat Acclimatisation

The body can adapt significantly to heat with consistent exposure over 10 to 14 days. During acclimatisation, plasma volume expands, sweat onset occurs earlier, and the cardiovascular system becomes more efficient. Reduce intensity by 20 to 30 percent when starting outdoor training in a new season.

Hydration and Electrolytes

Drinking water alone is not sufficient for long training efforts in the UAE. Sodium, potassium, and magnesium are lost through sweat and must be replaced. Sports drinks or electrolyte tablets can help maintain balance during efforts longer than 45 minutes.

Footwear and Surface Choices

Asphalt in Dubai can reach extreme temperatures that conduct heat through shoe soles and increase blister risk. Choosing appropriate footwear and training on shaded paths or indoor tracks where possible reduces both thermal stress and impact-related injury risk.
