Why UAE Residents Frequently Fall Ill Now

The Downside of Pleasant Weather: Why Are So Many Getting Sick in the UAE?

As cooler temperatures arrive in the United Arab Emirates, more residents are taking advantage of the fresh air and pleasant evening breezes. Many take sunset walks, have weekend barbecues in their gardens, or meet friends at the beach. Following the scorching summer, this mild weather is a relief—not too hot, not too cold, just ideal.

However, doctors warn that this period of fluctuating temperatures can lead to illness for many. The combination of air-conditioned interiors, still-warm afternoons, and cool evening breezes can place a surprising strain on the body—especially if one frequently transitions between these environments.

Sudden Temperature Changes: Hidden Danger to the Immune System

The human body is fundamentally "programmed" to gradually adapt to environmental changes. For instance, when suddenly moving from a dry, cool office to a humid, warmer outdoor space—or vice versa—our body’s defense mechanisms, particularly the nasal and throat mucous membranes, come under significant stress.

This abrupt transition causes the blood vessels to constrict and expand, irritating the mucous membranes. As a result, they dry out or swell, becoming less effective at preventing virus infiltration.

Symptoms Mainly Spread Through Children

Medical experiences suggest that the first wave of illnesses often starts with schoolchildren. In nurseries, schools, and outdoor playgrounds, infections spread quickly, with children bringing viruses home to their families. Parents then pass it on to colleagues at work, potentially leading to widespread community illness in a short span.

Common complaints during this time include sore throats, nasal congestion, coughs, mild fever, and general fatigue. While these symptoms are primarily viral in origin and subside within 5-7 days, some cases—especially those with fever, chest pain, or difficulty breathing—may require medical attention.

Air Conditioning Exacerbates the Issue

Despite the milder weather, many still use air conditioning, particularly in the afternoons when temperatures can still be high. However, overly cold indoor climates significantly dry the air, leading to throat dryness and nasal passage irritation. When coupled with the warm-humid outdoor air, the nasal mucosa—our primary defense against pathogens—becomes overwhelmed and more susceptible to viruses.

Who Is Most Affected?

In addition to children, office workers are also highly exposed to temperature fluctuations. They often spend entire days in air-conditioned settings, only to be met by a sudden warmth when stepping outside. This is especially true if indoor temperatures are around 21-22 °C while outside it’s over 30 degrees.

Another group affected is couriers and delivery personnel, who constantly shift between indoor and outdoor environments. Although their bodies may develop some level of adaptability over time, the frequent transitions can still be challenging for their physiology.

Cold Doesn’t Directly Cause Illness—But It Plays a Role

Several experts emphasize that temperature change alone doesn’t necessarily cause illness. Healthy individuals can generally adapt well to these changes. Problems arise when the respiratory tracts dry out, or the immune system is already weakened—perhaps due to lack of sleep, stress, poor nutrition, or chronic conditions like asthma or diabetes.

A balanced diet, adequate sleep, and regular fluid intake offer better protection than merely trying to avoid temperature fluctuations.

What to Watch in Cooler Months?

Doctors suggest maintaining indoor temperatures that are not too cold. An ideal range, especially at night when the body naturally slows down and rests, is 23–25 °C. There is no need to completely turn off air conditioning, but it’s advisable to set fans to "auto" mode or use "sleep" mode.

Other helpful tips include regular handwashing, avoiding crowded places during flu season, and preventive vaccinations like the annual flu shot. This is especially recommended for those prone to respiratory illnesses.

Summary

The milder autumn-winter period in the UAE indeed offers the chance to spend more time outdoors, enjoy fresh air, and rediscover the joys of communal life. Yet, we must not forget that sharp temperature changes, air conditioning use, and immune system overload can easily lead to illnesses.

The key is moderation: don’t over-cool indoor areas, allow your body time to adapt, and focus on the fundamentals of health—sleep, hydration, proper nutrition. This way, we can safely enjoy one of the UAE’s most pleasant times of the year.
