A research group at Nagoya University in Japan has reported that a group of neurons, called EP3 neurons, in the preoptic area of the brain play a key role in regulating body temperature in mammals.

Scientists think they may have finally discovered the reason why human body temperature has been decreasing over the past few centuries—gut microbes. A paper published in the American Journal of ...

Common knowledge says that your body temperature should be 98.6 degrees F and that a high or low body temperature signals something is wrong. But that's not quite true. In general, normal body ...

In hot environments, EP3 neurons in the preoptic area continually send inhibitory signals with GABA to suppress sympathetic outflows to defend body temperature from ambient heat. In cold environments ...

Throughout history, people have had to find ways to cope with varying environmental conditions. Whether they lived in a hot or cold climate or had access to plentiful or limited water, they adapted ...

Feeling cold all the time is not just a comfort issue. It can be an early warning sign of anemia, metabolic slowdown, or hormonal imbalance. Identifying and correcting the root cause can restore ...

These symptoms make it all the more incredible that in 1999, radiologist Anna Bågenholm made a full recovery after her body temperature dropped to 56.7 degrees Fahrenheit. It’s the lowest body ...

When medical professionals note a patient’s temperature dropping in the final hours of life, they’re witnessing one of the most reliable biological signals of approaching death. This temperature ...

This lesson plan teaches students how the human body self-regulates to maintain a stable internal environment despite changes in the external environment -- a process called homeostasis. Most of the ...
