Cold exposure causes blood vessels to constrict and increase blood pressure, heart rate, and heart muscle work. The combination of cold and exertion puts the cardiovascular system under even more strain. Cold temperatures are linked to an increased risk of myocardial infarction and sudden cardiac mortality, as well as increased heart symptoms (angina, arrhythmias). When exercising, patients with coronary artery disease should limit their exposure to cold, dress warmly, and cover their faces. Or if you have any heart disorder, you need to keep an AED machine with you all the time. It is readily available on AED superstores also in stores online.
Old concepts may lead us to believe that more unfavorable health impacts occur during periods of intense cold, but the reality is quite different. Extreme temperatures (cold or hot) accounted for only 0.86 percent of all deaths in a study of 74,225,200 deaths that occurred between 1985 and 2012 in 13 powerful nations across five continents, while the majority of cold-related deaths occurred at moderately cold temperatures (6.66 percent).
Hypertension is more common in colder climates or during the winter. Cold winters worsen hypertension and increase the risk of cardiovascular events such as myocardial infarction and stroke in people with hypertension.
Failure of The Heart
Patients with heart failure hearts cannot pump enough blood to maintain the blood flow required to meet the body’s needs when the heart’s workload increases in cold weather or when they must exert sustained physical effort, patients with heart failure do not have much leeway. The combination of cold and exercise reduces the performance of people with heart failure.
