Cold weather is known to impact cholesterol levels, leading to an increase in low-density lipoprotein (LDL), commonly referred to as bad cholesterol. According to Dr. Anjan Siotia , Director of Cardiology, BM Birla Heart Hospital, this is primarily because the body’s metabolism slows down during the winter months, and blood flow through the arteries is reduced due to constricted blood vessels.
“Combined with dietary patterns during this season, such as an increased reliance on high-fat comfort foods, these factors contribute to a rise in cholesterol levels. Reduced physical activity, often caused by shorter days and lower temperatures, further exacerbates the issue. Studies suggest that during the colder months, individuals with existing cholesterol problems or heart conditions are at a higher risk of complications, such as heart attacks or strokes,” Dr. Siotia told Financial Express.com.
To manage cholesterol levels effectively, it is essential to focus on a heart-friendly diet rich in seasonal vegetables, whole grains, and healthy fats while avoiding trans fats and refined sugars, he said.
According to Mayo Clinic, high cholesterol has no symptoms. A blood test is the only way to detect if you have it.
Regular exercise, even light indoor workouts, can also help maintain cholesterol levels. Monitoring one’s lipid profile during winter is particularly important for those at risk to prevent long-term complications, he added.
