Heat waves strain moods; specialists warn of psychological repercussions

As summer heat waves intensify, experts are highlighting their significant impact on mental health, beyond the immediate physical risks. Psychologists emphasize that prolonged exposure to high temperatures affects the brain, influencing mood, emotional regulation, and behavior.

During summer, with successive heat waves and rising temperatures, attention is often focused on physical risks like dehydration and heatstroke, while psychological effects remain less discussed despite their importance and direct impact on quality of life.

Studies indicate that constant high temperatures can lead to increased feelings of stress, anxiety, irritability, and difficulty concentrating. Sleep disturbances are also common, which in turn disrupt emotional balance and heighten sensitivity to daily pressures. These effects can be particularly pronounced for individuals with existing mental health conditions.

For those with anxiety disorders, heat can trigger panic attacks due to symptoms like sweating and rapid heartbeat, which might be misinterpreted as signs of serious illness. Individuals with depression may experience increased fatigue, lethargy, and reduced motivation. Furthermore, people with bipolar disorder might face a higher risk of manic episodes, while those with schizophrenia could see a worsening of hallucinations or delusions due to heat stress, dehydration, and lack of sleep.

Research indicates that continuous exposure to high temperatures may lead to increased feelings of stress and anxiety, irritability, decreased ability to concentrate, mental fatigue, and sleep disturbances, which are among the most common problems during summer.

The psychological toll of heat extends to social interactions, potentially increasing family conflicts and workplace tensions due to heightened irritability and reduced patience. Children, the elderly, individuals with chronic illnesses, pregnant women, outdoor workers, and those lacking social support are identified as the most vulnerable populations to these mental health impacts. Experts stress the need for a comprehensive approach to public health that addresses both the physical and psychological consequences of extreme heat.

Heat does not directly cause these disorders, but it can exacerbate their symptoms or increase the risk of relapse in people who already suffer from them.
