How does extreme summer heat trigger underlying diseases and worsen symptoms, and what are your thoughts on managing such risks in a hot climate like the UAE?

Extreme summer heat does more than cause dehydration or sunstroke—it can trigger dormant medical conditions or worsen symptoms in people with chronic illnesses. For example, individuals with multiple sclerosis (MS) often experience worsened fatigue, mobility issues, and vision disturbances in the heat due to Uhthoff’s phenomenon, where increased body temperature slows nerve signal transmission. Similarly, heat can strain the heart, impair kidney function, and exacerbate neurological conditions in children. Experts recommend preventive strategies like staying hydrated, avoiding the sun during peak hours, and using cooling tools. The UAE is already leading with accessible city designs and has launched the Universal Design for Inclusion Programme to build on this momentum. Do you believe enough is being done to protect vulnerable individuals during extreme heat waves? What measures would you like to see implemented?
