This common UAE summer effect could be worsening your health; doctors explain
As summer temperatures soar across the UAE, doctors are warning that extreme heat can trigger underlying health conditions and worsen symptoms in vulnerable individuals, particularly those with chronic neurological and cardiovascular diseases.
While most people associate high temperatures with heat stroke and dehydration, medical experts say the impact goes deeper, often unmasking or aggravating dormant conditions.
Among the most affected are patients with Multiple Sclerosis (MS), a neurological disorder that impacts the central nervous system.
What is Multiple Sclerosis?
Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (brain, spinal cord, and optic nerves) by damaging the protective myelin sheath surrounding nerve fibers. This damage disrupts nerve signal transmission, leading to symptoms such as muscle weakness, numbness, vision problems, difficulty walking, coordination issues, fatigue, and cognitive impairments.

'Between 60 and 80 percent of people with MS report a worsening of symptoms such as fatigue, mobility issues, and visual disturbances during hot weather,' said Professor Anu Jacob, Director of Multiple Sclerosis and Autoimmune Neurology at Cleveland Clinic Abu Dhabi, as told to Khaleej Times.
This temporary flare-up, known as Uhthoff's phenomenon, occurs when a rise in body temperature affects damaged nerves. Symptoms generally subside with rest and cooling.
Jacob said hydration, cooling vests, and avoiding peak outdoor hours are key to symptom management. He also noted the UAE's efforts in building accessible, shaded, and air-conditioned public spaces, which are crucial for people with chronic conditions.
According to a report by Khaleej Times, to move toward accessibility, the National MS Society has introduced the Universal Design for Inclusion Programme, partnering with six UAE universities to foster student-led innovations in inclusive infrastructure.
Warning signs of severe heat-related illness include confusion, fainting, rapid heart rate, and cessation of sweating, which may require medical attention.
Doctors stress that early intervention and preventive care are essential for at-risk groups.
