Understanding how cold weather can affect your heart health
In order to maintain the body temperature throughout the winter, our bodies go through specific physiological and biochemical changes. The cold can constrict your blood vessels and coronary arteries, resulting in high blood pressure, restricted blood flow, and a decreased supply of oxygen to the heart, blood clotting which can lead to a heart attack. In addition, to maintain a healthy body temperature, your heart has to work more in the cold. Hypothermia is a disorder that occurs when the body loses heat more quickly than usual, causing heart muscle damage. Children and the elderly are especially vulnerable. Elderly adults may also have less subcutaneous fat and a reduced capacity to perceive temperature, allowing them to endure hypothermia without realising it.

Some of the healthy tips to follow during the winter are;
· Stay warm: Limit your time spent outside in the cold weather, and if you must go out, dress warmly in layers, cover your head and hands, and wear warm socks and shoes.
· Overheating oneself is not a good Idea: Overheating can occur when you dress warmly and then engage in physical activity. When blood vessels dilate too fast as a result of overheating, hypotension (low blood pressure) develops in those who have cardiac difficulties.
· Obtain a flu shot: Winter also increases your chances of catching the flu because of the low humidity caused by cold weather and indoor heating. Anyone with heart problems is at risk from the flu.
· Regular exercise: It is essential, with at least 30 minutes of activity every day in chilly weather. However, avoid exercising outside first thing in the morning. Indoor activities such as static cycling, treadmill running, and yoga are also good options.
· Maintain your diet: It is ideal to limit the amount of salt and sugar intake in your diet. Excessive sugar can cause insulin resistance, obesity and diabetes and too much can cause water gain and high blood pressure, which can lead to heart failure, heart attack and stroke. Avoid consuming high protein during winter, it can cause a build-up of mucus in your throat. And while cooking, use polyunsaturated cooking oils such as safflower oil or mustard oil.
· Avoid or limit your intake of alcoholic beverages: Too much alcohol can cause blood vessels in the skin to dilate, making you feel warmer while pulling heat away from your essential organs. Hence, it is important to completely avoid or limit the amount of your intake.
· Regular Health Checks: Everyone, including those with no medical history, should undergo regular health check-ups.
