Scientists discover human brain is hotter than previously thought

Our human brain performs a variety of activities and functions throughout the day. The temperature of the human brain varies throughout the day. Now, according to new research, the normal temperature of the human brain swings significantly higher than previously thought, and this could be a sign of good brain function. The study noted that some regions of the deep brain can reach temperatures of up to 40 °C, although this varies depending on sex, time of day and other factors. In comparison, the average oral temperature in humans is normally less than 37 °C. Researchers believe that this is not a sign of malfunction, but rather evidence that the brain is functioning normally. Data from brain-injured patients in intensive care, where direct brain monitoring is usually required, have previously been used in human brain temperature studies.

Using a brain scanning tool called magnetic resonance spectroscopy, researchers were recently able to detect brain temperature in healthy individuals (MRS). However, until now, MRS had not been used to examine how brain temperature changes during the day, or how one’s ‘body clock’ affects it.

The new study is the first to create a 4D map of the temperature of a healthy human brain. By showing how much brain temperature changes by brain region, age, sex and time of day, this chart defies many previously held ideas.

The study also looked at data from traumatic brain injury patients, finding that the presence of daily brain temperature cycles is highly associated with survival. These findings may aid in the diagnosis, diagnosis and treatment of brain injuries.

the results of the study were published in the magazine Brain,

In order to “interpret the patient analysis”, the researchers “recruited 40 healthy adults (20 men, 20 women, 20-40 years old) for brain thermometry using magnetic resonance spectroscopy”, the report said. On the same day, participants were scanned in the morning, afternoon and late evening.

The brain temperature in healthy participants ranged from 36.1 °C to 40.9 °C, the report said.

On average, the brains of women are 0.4 degrees Celsius warmer than the brains of men. Since most women were scanned in the post-ovulation phase of their cycle, their brain temperatures were about 0.4 degrees Celsius warmer than those measured in the pre-ovulation phase. This difference is most commonly due to the menstrual cycle.

Dr. John O’Neill, group leader in the MRC Laboratory for Molecular Biology, Told The most surprising discovery from UK Research and Innovation is that the healthy human brain can achieve a temperature that would be diagnosed as a fever elsewhere in the body. In the past, such high temperatures were measured in individuals with brain injuries, but were thought to be due to injury. Researchers found that brain temperature decreases before people go to sleep at night and rises during the day. There is evidence to doubt that daily variation is linked to long-term brain health, which the researchers like to look at further.

Researchers are now hoping the 4D brain temperature map can be used as a reference guide for what a healthy brain should look like. However, a lot of data is needed from a large group of people to make it really useful.
