Living in the UAE means long summers, strong sun, and temperatures that can climb past any comfortable limit. Anyone who has spent even one season here knows how quickly heat can wear you down. What many people don’t realize is that excessive heat not only affects people working outdoors, but can also strain the body during routine tasks like walking to your car, climbing a flight of stairs, or waiting at a bus stop.
Over the past decade, doctors in the region have seen a steady rise in cases linked to dehydration, heat exhaustion, and excessive body heat buildup. A large review published in 2019 by the International Journal of Environmental Research and Public Health found that Gulf countries record some of the highest heat-related illness rates globally.
Another earlier report from the UAE’s National Center of Meteorology noted that the average annual temperature in the UAE increased by approximately 1.8°C between 1901 and 2017.
This guide breaks down what happens to your body in extreme temperatures, how to protect yourself, how to help someone in trouble, and the smart habits that make daily life safer during the hottest months.
Why UAE’s Climate Is Hard on the Body
The combination of high temperature, humidity, and sun exposure makes excessive heat more dangerous here than in many other places. When humidity rises, sweat does not evaporate properly, meaning your body struggles to cool itself.
Research published by Gagnon and Kenny in the Journal of Applied Physiology in 2012, high humidity significantly reduces the body’s ability to dissipate heat because sweat cannot evaporate efficiently. During UAE summers, humidity can reach 80 percent or more along the coast.
This trap of heat plus humidity leads to:
- Faster dehydration
- Rapid rise in core temperature
- Fatigue even with minimal activity
- Higher risk of heat exhaustion and heatstroke
- People with existing heart conditions, diabetes, high blood pressure, or kidney issues feel the impact even more strongly.
Signs Your Body Is Struggling with Excessive Heat
Understanding early symptoms can keep a simple problem from becoming an emergency. Many people don’t realize their body is overheating until the situation has already escalated.
Early Warning Signs
- Headache
- Dizziness
- Trouble in maintaining focus
- Sudden tiredness
- Thirst that doesn’t seem to go away
- Hot skin
- Muscle cramps
Serious Symptoms
You need to get medical attention right away if you notice these signs
- Confusion
- Fainting
- Fast pulse
- Vomiting
- Skin that feels dry and extremely hot
- Altered behavior
As per findings published in Environmental Health in 2014 by Lundgren et al., people working or moving in hot climates often overlook early symptoms of heat strain due to limited awareness, which increases the likelihood of complications from excessive body heat.
Who Is Most at Risk During Excessive Heat?
While everyone feels the impact of hot weather, some groups are more vulnerable.
Higher-risk groups include:
- Outdoor workers
- Children under 12
- Adults over 60
- People with chronic illnesses
- Pregnant women
- Athletes training outdoors
- Tourists not used to the climate
Research conducted in Qatar suggests that outdoor workers exposed to excessive heat for long periods have a higher chance of developing heat exhaustion symptoms.
Smart Hydration Habits for Hot Weather
Proper hydration is the most reliable defense against excessive heat. It sounds simple, but many people only drink once they feel thirsty. By then, dehydration has already started.
How Much Should You Drink?
Hydration needs vary, but health authorities suggest:
Light activity: 2.5 to 3 liters per day
Moderate outdoor activity: 3.5 to 4 liters per day
Heavy outdoor labor: Up to 5 liters per day (with electrolyte replacement)
According to a 2011 study published in the British Journal of Nutrition by Ganio et al., even mild dehydration can impair cognitive function, mood, and physical performance.
What Helps
- Water
- Oral rehydration solutions
- Coconut water
- Sugar-salt hydration drinks
What Slows Cooling & Should Be Avoided
- Energy drinks
- Excess caffeine
- Soft drinks
Clothing Choices That Help
Your clothes play a bigger role than you may think. Dark, tight, or synthetic fabrics trap warmth and prevent the body from releasing excessive body heat.
Better Options
- Light colors
- Breathable cotton or linen
- Loose-fitting layers
- Wide-brim hats
- UV-protective sunglasses
Research widely supports the principle that light-colored, tightly woven fabrics help regulate body temperature in extreme heat by reflecting sunlight and providing effective sun protection.
How to Plan Your Day Around Excessive Heat
Heat safety is not only about hydration or clothing. It is also about timing.
Smart Scheduling Tips
- Avoid outdoor activity between 12 pm and 4 pm
- Take frequent shade breaks if you work outside
- Use cooling towels when possible
- Keep a bottle of water within reach at all times
- Never sit in a parked car, even for a few minutes
Studies show that the temperature inside parked cars increases rapidly within a few minutes. Sometimes, within ten minutes or less, the temperature reaches dangerous levels.
Cooling Down Quickly: Practical Steps
When your body starts to feel overwhelmed, fast cooling helps prevent complications.
- Ways to Lower Heat Fast
- Sip cool water slowly
- Move into an air-conditioned or shaded space
- Place a damp cloth on the back of your neck
- Rest your feet in cool water
- Loosen tight clothing
- Avoid heavy meals until you cool down fully
- If symptoms of excessive heat continue longer than 20 minutes, medical attention is recommended.
Helping Someone Showing Signs of Heat Distress
Heat emergencies escalate quickly. Staying calm and taking the right steps can make a big difference.
What to Do
- Move the person to shade or AC.
- Encourage slow, steady drinking.
- Apply cool water to the arms, legs, and face.
- Fan the person lightly.
- If they faint or become confused, call emergency services immediately.
According to the World Health Organization’s Heat and Health Guidelines (2021), rapid cooling is one of the most effective early actions in managing heatstroke.
Helping Someone Showing Signs of Heat Distress
The UAE has strict regulations to protect workers during peak heat. Hydration breaks and periods of shaded rest must be provided to the workers by employers.
- Worker Safety Tips
- Drink before you get thirsty
- Take shade breaks every 30–45 minutes
- Use cooling towels
- Avoid energy drinks during shifts
- Eat lighter meals during the day
- The International Labour Organization also reports that scheduled rest breaks reduce heat stress-related illness in high-exposure jobs.
Foods That Help Your Body Stay Cool
Eating the right foods supports the body’s ability to manage excessive heat.
Helpful Foods
- Fresh fruits, high in water
- Cucumbers
- Leafy vegetables
- Yogurt
- Soups
- Electrolyte-rich foods
Foods to Limit
- Heavy fried meals
- Spicy dishes (can increase sweating and boost excessive body heat)
- Excess salt
- High sugar snacks
