As cold waves sweep through regions like North India and cities like Delhi, the drop in temperatures can exacerbate a range of health conditions. In Delhi, the cold wave and severe cold wave warnings have become more frequent in recent years. While the chill can feel refreshing, it also poses significant risks to vulnerable individuals. Here’s how certain diseases flare up during a cold wave in Delhi and across India, and the steps you can take to manage them.
1. Respiratory Infections (Common Cold, Flu, Pneumonia)
Why it flares up: During a cold wave, especially in cities like Delhi, cold wave alerts signal a dramatic drop in temperatures, which weakens the immune system and encourages the spread of respiratory infections like the common cold, flu, and pneumonia.
Symptoms: Cough, fever, congestion, body aches, and difficulty breathing (in severe cases).
Management Tips:
Vaccination: Get the annual flu shot to protect against flu strains that peak during cold wave conditions. Also get pneumnia vaccine from your nearby clinic.
Hygiene Practices: Wash hands frequently and wear masks in crowded places to reduce the spread of viruses.
Home Care: Stay hydrated, use warm steam inhalation, and rest.
Medical Attention: Seek immediate medical help if symptoms worsen or if breathing becomes difficult.
2. Asthma and Chronic Obstructive Pulmonary Disease (COPD)
Why it flares up: The cold weather triggers bronchial spasms and reduces air quality, making it harder for asthma and COPD patients to breathe. In Delhi, a cold wave can cause pollution levels to spike, aggravating these conditions.
Symptoms: Wheezing, breathlessness, chest tightness, and coughing.
Management Tips:
Protective Measures: Cover your nose and mouth with a scarf or mask to warm the air before it enters the lungs.
Medication: Use prescribed inhalers and carry a rescue inhaler during cold spells.
Humidification: Keep indoor air moist with a humidifier to prevent dryness.
Avoid Triggers: Stay indoors when pollution levels rise and avoid exposure to cold, dry air.
3. Cardiovascular Issues (Heart Attacks, Hypertension)
Why it flares up: During a cold wave in Delhi, cold temperatures can cause blood vessels to constrict, increasing blood pressure and placing additional stress on the heart. This increases the risk of heart attacks, strokes, and other cardiovascular issues.
Symptoms: Chest pain, palpitations, fatigue, dizziness, and shortness of breath.
Management Tips:
Dress Warmly: Wear layers to retain body heat and prevent sudden temperature drops, especially during a cold wave alert.
Avoid Overexertion: Take breaks during physical activities such as shoveling snow or brisk walking in cold conditions.
Monitor Blood Pressure: Keep track of blood pressure regularly, particularly for those with existing hypertension.
Diet: Focus on heart-healthy meals, including warming soups and stews with lean protein and vegetables.
4. Arthritis and Joint Pain
Why it flares up: Cold waves can cause the body’s joints to become stiffer and more painful, particularly for people with arthritis. In places like North India, where temperatures can plummet during the winter, the cold can significantly reduce joint mobility.
Symptoms: Increased pain, swelling, and stiffness in the joints, especially in the knees, hands, and back.
Management Tips:
Stay Active: Engage in gentle activities like stretching, yoga, or walking to keep joints moving and prevent stiffness.
Warm Compresses: Apply heating pads or warm towels to painful joints for relief.
Layer Up: Dress warmly, focusing on protecting the joints with thermal wear and gloves.
Supplements: Consider taking vitamin D and omega-3 fatty acids, which may help reduce inflammation.
5. Raynaud’s Phenomenon

Why it flares up: In extremely cold temperatures, like those during a cold wave in Delhi, the small blood vessels in extremities such as the fingers and toes constrict, limiting blood flow. This leads to episodes of Raynaud’s phenomenon.
Symptoms: Pale or bluish fingers and toes, numbness, and tingling sensations.
Management Tips:
Warmth: Always keep extremities covered with thermal gloves and socks to improve circulation.
Avoid Cold Exposures: Limit outdoor activities when cold wave conditions are severe.
Medication: Consult a doctor about medications like calcium channel blockers to improve blood flow.
Stress Management: Practice relaxation techniques such as meditation to reduce stress-induced flare-ups.
General Tips for Managing Health During a Cold Wave
Stay Indoors: Limit outdoor exposure when the Delhi weather cold wave warnings are in effect.
Warm Up Your Home: Use safe heating methods to maintain a comfortable indoor temperature.
Stay Hydrated: Drink warm liquids like herbal teas or soups to stay hydrated in the cold.
Eat Immunity-Boosting Foods: Focus on warming, nutrient-rich foods such as soups, stews, and seasonal vegetables to support overall health during the cold wave in India.
Layer Clothing: Wear multiple layers to keep your body temperature regulated and prevent hypothermia.
With proper management and precautions, you can stay healthy and comfortable even during a severe cold wave. Pay attention to cold wave alerts and adapt your routine to minimize the risk of flare-ups of common health conditions.
