Our heart is shrouded in fat. No one knows exactly why this fat is needed. Maybe this is a source of energy for the heart muscle. It may mechanically support coronary arteries.
We have already discussed this fat in the story about atrial fibrillation in fat men.
It is suspected that this fat is not always harmful and nasty. He can behave just like brown. That is, it is useful and generates heat.
Back in the seventies of the last century, the fat around the heart was studied in detail and it turned out that with age it looks less and less like a healthy brown fat and gradually degenerates into ordinary white harmful fat.
Hypothermia
The suspicion immediately arose that this was why the heart of the elderly was sensitive to hypothermia.
If an elderly person is very cold, then life-threatening heart rhythm disturbances are easily triggered. Therefore, old people in a state of hypothermia are not pushed or shifted once again. You can read about it at the link below.
Overheat
On the other hand, in obese people, much of the brown fat in the heart is replaced by regular white fat. It is believed that this can protect the fat man's heart from overheating.
It turns out that young people literally have a warm heart, but most likely it is not very useful for him to be too hot.
