She explained that hypothermia poses a particular risk to the cardiovascular system, as it increases the likelihood of myocardial infarction, stroke, and cardiac arrhythmia.
Dr. Khachirova pointed out that hypothermia occurs when the body loses heat faster than it produces it, such as through exposure to cold water, prolonged exposure to extremely cold weather, or exposure to strong winds that increase heat loss. Exhaustion, overwork, alcohol consumption, and drug use are also contributing factors to hypothermia.
The primary mechanism by which hypothermia affects the body is the constriction of blood vessels and a decrease in blood flow to the outer layers of the body , which threatens the circulation of internal organs. The doctor explained that the heart is very sensitive to temperature changes, as sudden changes in electrical signals can cause arrhythmias, and increased vascular resistance puts more strain on the heart muscle. People with chronic cardiovascular disease are at higher risk of myocardial infarction and stroke.
It is not only the heart that is affected; an increased risk of infection and inflammation due to a weakened immune system is among the other risks of hypothermia.
Khachirova stressed the importance of prevention , noting the need to wear warm clothes, protect the head and hands, avoid prolonged exposure to the cold, and refrain from consuming alcohol in cold weather.
