According to them, prolonged exposure to high temperatures can significantly alter human mood and lead to heightened levels of aggression, irritability, and stress.
They, however, advised Nigerians to stay hydrated and take preventive measures to avoid heat-related illnesses.
Speaking with PUNCH Healthwise, a psychologist, Dr. Ifeoma Onaje explained that extreme heat places a significant strain on the body, which can, in turn, manifest in emotional instability.
“When the body experiences intense heat, it can cause discomfort, dehydration, and fatigue. These physical conditions can trigger emotional responses that are often negative. People may feel more irritable, anxious, or even hostile in situations they would typically handle with more calmness,” she said.
Onaje pointed out that the brain’s ability to regulate emotional responses weakens when the body is under heat stress, making individuals more prone to aggressive behavior.
The mental health expert stated that the heat is also known to exacerbate mental health disorders, particularly those linked to anxiety and depression.
She added, “For individuals already struggling with mental health conditions, extreme heat can act as a trigger, intensifying their symptoms. The discomfort and irritability caused by high temperatures can make it more challenging to cope with everyday stressors.”
Similarly, a consultant psychiatrist, Dr. Idris Adekunle emphasised the strong connection between heat and emotional disturbances.
He pointed out that when the body experiences extreme temperatures, it could trigger a cascade of physical and emotional responses.
“Heat stress activates the body’s fight-or-flight response, which releases stress hormones like cortisol. This can create feelings of frustration, restlessness, and in some cases, aggression. It’s a natural physiological reaction to an environment that is difficult for the body to manage,” he explained.
Although the impact of extreme weather on mood is well-documented, Adekunle noted that the effects of excessive heat can be more acute and immediate.
“Unlike cold weather, where people tend to stay indoors and bundle up, heat often forces people out into uncomfortable and stressful conditions. This constant exposure can lead to emotional volatility, especially in urban areas where air conditioning and access to water may be limited,” he added.
According to the World Health Organisation, heatwaves, or heat and hot weather that can last for several days, can have a significant impact on society, including a rise in heat-related deaths.
The global health body noted that heatwaves are among the most dangerous of natural hazards, but rarely receive adequate attention because their death tolls and destruction are not always immediately obvious.
WHO, however, issued guidelines on how to stay safe during heatwaves.
The global health body noted that preparing for a heatwave was crucial to preventing heat-related illnesses.
It advised people to be aware of the temperature and humidity levels in their area and plan their activities accordingly.
WHO also recommended that people keep an emergency kit at home that contains essential items such as oral rehydration salt packets, a thermometer, water bottles, towels or cloths to wet for cooling, a handheld fan or mister with batteries, and a checklist to identify and treat symptoms of heat stress.
The agency further advised people on how to get help in case of a heat-related emergency. This includes noting the contact information for the nearest healthcare provider or ambulance/transport services.
To keep homes cool, WHO recommended closing curtains during the hottest parts of the day and opening windows at night to cool down the house. Using fans and coolers can also help to keep homes cool.
