Heatwave Effects: Why do people become more irritable in 50°C heat? Science reveals the truth.

High Temperature Effects on the Brain: When temperatures exceed a certain limit, people tend to feel more irritable, angry, and restless over small things. Let us explain why this happens.

 

Why do people become angrier in summer?

How Extreme Heat Affects Human Behavior: Extreme heat not only negatively impacts the body but also human behavior and mood. When temperatures exceed a certain limit, people become more irritable, short-tempered, and restless over small things. Many people think this is simply due to fatigue or uncomfortable weather, but now science and doctors have explained the real reason behind it.

Do you start getting more angry?

In fact, in extreme heat, the body constantly tries to cool itself down. This puts additional pressure on the body. Dr. Albers, an expert at the health information organization Cleveland Clinic, explained that when the weather is very hot, the body goes into overdrive mode. This causes cortisol, the stress hormone, to increase in the body. This hormone makes people easily angry, restless, and mentally exhausted.

What problems arise as the heat increases?

According to Dr. Albers, heatwaves have been associated with an increase in emergency room visits, aggressive behavior, violence, and even suicide. Scientists believe that when the body is constantly battling the heat, the brain has less energy to regulate emotions. This makes even small problems seem significant.

What has the most impact?

Summer has a major impact on sleep. Humid nights can make it difficult for people to sleep properly. Frequent awakenings, delayed sleep, and short sleep hours prevent the brain from fully resting. Consistently poor sleep for several days can make a person feel more irritable, impatient, and stressed. This is why many people experience sudden mood swings during the summer.

Is this problem caused by dehydration?

Additionally, dehydration also impacts mental health. Excessive sweating leads to dehydration. According to Dr., the brain needs adequate water to function properly. When dehydration is low, problems like headaches, fatigue, difficulty concentrating, restlessness, and low mood can increase. People also often experience anxiety and heart palpitations, which further increase anxiety.
