Kathmandu – Cardiologists are warning that the risk of heart attacks significantly increases during the winter season, particularly among individuals who already have pre-existing heart conditions. With falling temperatures, medical professionals urge vulnerable groups to exercise greater caution.
According to Dr. Aditya Mahaseth, a heart specialist at KMC Hospital, colder temperatures cause blood vessels to constrict, which increases blood pressure and places additional strain on the heart. This heightened pressure can lead to complications such as heart attacks, especially among the elderly or those with underlying cardiovascular issues.
“Cold weather causes the outer blood vessels to narrow, restricting blood flow and making it harder for the heart to pump efficiently. This is one of several reasons why heart attack risks surge in winter,” Dr. Mahaseth explains.
He adds that heart disease remains the leading global cause of death, and early detection through regular health checkups is vital. Lifestyle factors, such as poor diet, smoking, lack of physical activity, and stress, can significantly increase the likelihood of heart-related illnesses, regardless of age.
Alarming Rise in Young Heart Patients
While heart attacks were traditionally associated with individuals above 45, doctors are seeing a growing number of cases in people aged between 20 and 35. Dr. Mahaseth attributes this to sedentary lifestyles, excessive consumption of junk food, and rising rates of smoking among youth.
“Today’s lifestyle has changed drastically. People sit in front of computers all day, eat fast food, and skip physical activity. These habits are increasing heart risks at a younger age,” he says.
Studies have also shown a strong link between cholesterol buildup and heart blockages. High sugar intake, smoking, and lack of exercise further aggravate this issue, making young people increasingly vulnerable.
How to Reduce the Risk
Dr. Mahaseth stresses the importance of maintaining a balanced diet based on individual energy requirements. People with desk jobs need fewer calories than those engaged in physical labor. He recommends avoiding added sugars and processed foods, focusing instead on natural and home-cooked meals.
“Sugar isn’t essential for the body. Our diet should meet our physical needs, not exceed them. Excess intake leads to cholesterol buildup, which directly impacts heart health,” he explains.
Role of Smoking and Alcohol
While not everyone who smokes will suffer a heart attack, the risk is significantly higher among smokers. According to research, smokers are three times more likely to experience a heart attack compared to non-smokers.
“Smoking, combined with factors like high blood pressure, diabetes, or a family history of heart disease, drastically increases the chances of a heart attack,” says Dr. Mahaseth. “Even if someone doesn’t show symptoms, these factors are silently damaging the heart.”
Exercise Is Key
Physical activity plays a critical role in reducing heart disease risk. It improves heart function, helps regulate blood pressure and blood sugar levels, and aids in managing weight.
“Regular exercise keeps the cardiovascular system strong and burns off extra calories, which helps prevent cholesterol buildup,” he notes.
As winter continues, experts strongly recommend routine checkups, proper diet, physical activity, and reducing harmful habits to protect heart health—especially among those with prior heart conditions.
