Patients with cardiac issues, high blood pressure, or coronary heart disease are more susceptible to serious and even life-threatening complications due to how severely cold affects both healthy and hypertensive people's blood pressure and how badly it disrupts the functioning of several other body organs.
While extreme cold has already been affecting the majority of the country, recent rain in this area of the country and snowfall over hills in the adjacent mountain range have prompted a further drop in the mercury. According to health experts, in the current hard weather, chronic patients, including those with cardiac conditions, must avoid exposure to extreme cold, particularly from dusk
until dawn.
According to experts, when the temperature in wintertime drops below 0 degrees Celsius, the inhalation of extremely cold air causes the peripheral blood vessels to contract, which may be problematic for long-term patients, such as those with cardiac conditions.
According to studies, vasoconstriction, which is the narrowing of blood arteries as a result of contraction of the vessels' musculature, has very harmful impacts on the health of people with heart conditions and hypertension since it may raise blood pressure.
Extreme cold has been found to represent a major risk to people with heart disease, mostly because the harsh weather conditions interfere with the diet and exercise routines of heart patients. It is essential for chronic patients to maintain a regular routine after lowering in mercury since both the systolic and diastolic mean blood pressures among adults, the elderly, and children demonstrate a seasonal high during the winter and trough in summer.
According to experts, chronic patients with heart disease, high blood pressure, and diabetes may experience complications once extremely cold weather sets in. The situation is made even more concerning by the fact that the majority of patients are not aware of the negative effects of cold weather on their health. A chronic patient should cover his nose correctly with a warm cloth before venturing outside in the morning, evening, or at night, according to experts, to prevent breathing in the chilly air.
The majority of chronic patients, such as those with heart disease or high blood pressure, become physically inactive in extreme cold, which prevents their bodies from losing salt that could be problematic for them. Patients with heart conditions and other chronic illnesses should engage in physical activity or go for regular midday walks.
Exercise is vital because it lowers blood pressure, blood cholesterol levels, blood sugar, blood clotting factors, blood vessel health, and inflammation.
Numerous studies have shown that the risk of coronary heart disease (CHD) in Pakistanis is among the highest in the world. Cardiovascular disorders account for 30 to 40 percent of all fatalities in Pakistan (CVD). About 200,000 people in Pakistan die from coronary heart disease each year, or 410/100000 of the population. In Pakistan, CHD is currently the main cause of death. Heart patients may be able to minimise the negative effects of extreme cold on their health by exercising caution and taking the appropriate safety precautions, according to experts.
