Heat Damages Liver and Brain: Study on Elderly Mice

Heat stress during heatwaves has a destructive impact on the liver, intestines, and brain of elderly individuals, according to experiments conducted on elderly mice at the University of California, Irvine. When rodents were exposed to heat stress, their livers showed significantly increased production of a protein called ORM2. Presumably, this is a compensatory mechanism during inflammation and gut imbalance. Additionally, ORM2 may adversely affect the brain's coordination with the liver and the gastrointestinal tract (GIT).
