Scientists have found out why the cold is felt more with age
Scientists from the United States explained why older people feel more cold. The scientific article was published in the journal Cell Metabolism.
Researchers from Yale and California Universities are confident that this is due to the fact that with age, the number of immune cells in the body that are responsible for restoring heat at low temperatures decreases. A person has a thermoregulation mechanism from birth. It works on the principle of generating heat energy from the body's fat reserves. Heat is restored by type II lymphoid cells ILC2.
An experiment was conducted with the participation of rodents. It turned out that the adipose tissue of mice loses ILC2 cells with age. Because of this, the ability to generate heat energy is reduced.
Scientists have tried to restore these cells. The drug method further reduced the tolerance to cold, as poor quality lymphoid cells multiplied. Only ILC2 transplantation from juveniles improved the thermoregulatory capacity.
Previously, scientists have found out what affects the attractiveness of the voice for men and women. During the experiment, the researchers recorded the voices of 42 people, which were then listened to by a group of volunteers.
