Study Report: Anna Andreasen, a PhD student at the Norwegian University of Science and Technology, said, “You will be really surprised to know that your brain can be damaged in summer, that is, heat has a lot of effect on the brain.” The study report states that living species, whether fish or humans, their brains start to perform poorly as the temperature rises. This is something that many people will surely have experienced on very hot days, but do you know what happens inside the body when the temperature outside gets too high?
The mind decides the changing nature of the organism
To answer this question, researchers from NTNU’s Department of Biology used genetic techniques combined with neurophysiological methods, saying that “we explored the factors that restrict an organism’s heat and tolerance.” Which organisms will thrive when the Earth’s temperature rises as a result of climate change, and why? “To find the answer to this question, we decided to look at the brain.”
Temperature affects the human brain a lot
Studies show that temperature affects the human brain a lot. Too much heat fills more anger and hatred inside a person. A research suggests that we are in our best mood at 12 to 21 degree Celsius. In such a temperature, we also get less angry.
The Lancet Planetary Health has studied the behavior of people living in 773 cities of America. In this study it has been found that due to excessive heat, anger increases inside the person. In desert areas where the temperature is found to be close to 42 to 45 degree Celsius, there was an increase of up to 22% in tweets containing hate speech.
Heat affects not only humans, but also the brains of living beings
Continental heat waves are becoming more common, and living organisms are also facing dangerously rising temperatures. Understanding what limits survival at extremely high temperatures is important for predicting how organisms will respond to climate change.
“Thermal tolerance has been studied for decades and it has been found that temperature affects brain activity.” To find out, researchers at NTNU in Trondheim studied the brain activity of newly hatched zebrafish larvae as the temperature around the larval fish progressively increased, and found that “these fish were genetically engineered to It has been shown that when neurons in the brain are activated, they emit fluorescent light.”
Fish lose balance due to heat
When the weather gets too hot, they lose their balance and swim in circles, with their belly up. The researchers stimulated fish larvae to see how they reacted. They suppress the tail of the larvae, which usually causes them to swim. Something strange happened when they raised the temperature. The fish died and started losing their ability to swim, which shows that our brains stop working due to heat.
