More News : With Basant Panchami marking a sudden change in weather, cold conditions have intensified across several regions. While snowfall in the hills has increased chill, Delhi, Uttar Pradesh and NCR are experiencing rain and strong winds, leading to a sharp drop in temperature. Health experts warn that such conditions can have a serious impact on the body, especially during extreme cold.
Doctors from Dr. Ram Manohar Lohia Hospital, New Delhi, have advised people to remain alert and take precautions. According to specialists, cold weather and snowfall affect the body in different ways. In severe cold, the body tries to conserve heat by narrowing the peripheral arteries in the hands and feet, a process known as peripheral vasoconstriction. While this reduces heat loss, it also decreases blood flow to extremities, causing fingers and toes to turn bluish. Prolonged exposure may even lead to gangrene.
In extremely cold regions, body cells—especially in fingers and toes—may freeze due to reduced circulation. This condition is known as frostbite, which can cause permanent tissue damage and, in severe cases, lead to amputation. Snow-covered areas also see a rise in slip-and-fall accidents, resulting in fractures and injuries.
Why Drinking Less Water Is Dangerous in Winter
Doctors point out that during winter, people often drink less water because they feel less thirsty, even though the body continues to lose fluids through sweat and respiration. Reduced water intake causes the blood to become thicker, increasing the risk of brain stroke and heart attack.
In heart patients, cold weather can raise blood pressure and cardiac workload, significantly increasing the chances of cardiac events.
Impact on Asthma, Breathing and Mental Health
Cold and dry air can trigger asthma attacks, sometimes referred to as cold-induced asthma. Dry air also affects nasal passages and bronchial tubes, leading to cough and breathing difficulties.
Additionally, prolonged cloudy weather and lack of sunlight may cause anxiety, stress and low mood in some individuals.
Hidden Danger of Heaters and Fire Pots
To escape the cold, many people use room heaters or fire pots (angithi) in closed spaces. Doctors warn that this can increase carbon monoxide levels, which may prove fatal. Dry hot air can also dry out nasal and bronchial linings, worsening respiratory issues.
How to Protect Yourself During Cold Weather
-
Keep your body properly warm and avoid direct exposure to cold
-
Wear multiple light layers instead of a single thick garment
-
Change wet clothes or socks immediately
-
Cover your head, ears, hands and feet
-
Drink adequate water, even if you don’t feel thirsty
-
Elderly people, children and heart patients should take extra precautions
Health experts stress that neglecting small precautions in winter can lead to serious health complications, making awareness and prevention essential.
