Even those working in air-conditioned offices can be vulnerable to heat-related health issues, experts told Khaleej Times. While many are aware of the physical effects of heat exposure, such as heat rash, heat cramps, heat exhaustion, and heat stroke, the mental health impacts are often overlooked. These can ultimately affect the productivity of those who work behind computers.

"Extreme heat not only poses serious physical health risks but also significantly impacts mental health," said Dana Berri, psychologist at Aman Lil Afia Clinic. Research has shown that heat waves and extreme temperatures can lead to various mental health issues, such as irritability and depression symptoms, and can influence behavior, leading to more aggression. Elevated temperatures have been linked to memory problems, reduced attention, and slower reaction times, she added. "Plus, there’s a 40 per cent likelihood of hospitalisation for mood disorders like depression and mania during periods of extreme heat."

Berri explained that the link between high temperatures and mental health involves a complex interplay of biological and psychological responses. The physical discomfort caused by heat stress can lead to psychological distress, which is further exacerbated by disrupted sleep patterns, as poor sleep can disrupt hormone balance, leading to increased levels of stress hormone.

Heat stress occurs when the body absorbs more heat from its surroundings than it can disperse. High ambient temperatures, humidity, physical activity, and insufficient water intake can lead to heat exhaustion. "Anyone exposed to high temperatures and humidity – especially if they are not getting proper hydration and cooling – can be vulnerable to heat stress," said Neeta Jhaveri, functional medicine practitioner and health coach at Wellth.

Heat stress affects mental health and well-being. "But it is also important to understand and recognise the symptoms of heat stress, as they may vary from person to person," said Dr Aida Al Suhaimi, a clinical psychologist at Medcare Kamali Clinic. Symptoms may include persistent tension, irritability, being easily irritable, poor sleep, decreased motivation, lack of interest in activities, and low mood. "It leads to poor sleep patterns and difficulty concentrating, and decreased work productivity that can trigger symptoms of depression and anxiety. If these patterns continue for a long time, depression and anxiety can worsen," Dr Al Suhaimi said.

To handle the symptoms, mindfulness and relaxation techniques could help, the expert said. "Good sleep hygiene, a healthy diet, and staying hydrated are essential." While it would be great to continue outdoor activities during the summer months, "be open to finding new ways to enjoy them", Dr Al Suhaimi said. "Stay flexible and explore different ways to deal with stress rather than relying solely on activities like walking."
