Dubai is known for its luxurious lifestyle and tall buildings, but it also faces a serious problem—extreme heat. In some areas of the United Arab Emirates (UAE), temperatures reach 45–50 degrees Celsius during the summer. Increased humidity makes the impact of the heat on the body even more pronounced.
Therefore, the question often arises as to how long one can stay in Dubai without using air conditioning. Specialists note that there is no definitive answer; it depends on numerous factors, including the person's age, health condition, hydration level, intensity of solar radiation, and air humidity.
According to Dr. Yazan Koujhan, a general practitioner at Medcare Medical Centre, the effects of heat in the UAE can occur very quickly. He explained that due to high temperature and humidity, the body cannot cool down effectively despite sweating. This significantly increases the risk of developing heat exhaustion, and subsequently, heatstroke. Initial symptoms include dizziness, profuse sweating, headache, nausea, weakness, and muscle spasms. If the condition does not improve after resting, drinking water, and being in a cool place, immediate medical attention is necessary.
Dr. Marisa Fernando, a family physician at Burjeel Medical Centre – Silicon Central Mall, Dubai, advised readers to change their daily routine during the hot season to ensure safety. She recommended exercising or working outdoors early in the morning or after sunset. It is important to avoid direct sunlight during the day, drink water regularly, and use a hat, sunglasses, and sunscreen when going outside.
Overall, experts emphasize that air conditioning systems in Dubai are installed in shopping malls, metro stations, offices, and most public places precisely so that people can protect themselves from the intense heat. If a person experiences symptoms such as confusion, fainting, vomiting, or an abnormal rise in body temperature in hot conditions, this should be considered heatstroke requiring immediate medical care.
Thus, there is no specific time limit for staying without air conditioning, but doctors agree that neglecting extreme heat can be dangerous. The best protection lies in adequate fluid intake, sun protection, and timely movement to cooler indoor spaces.
