Many parts of India, especially in the south, are already experiencing extremely high temperatures, marking the early arrival of summer and heatwaves, according to the Indian Meteorological Department (IMD). The IMD has predicted heatwaves in Konkans, coastal Karnataka, and North Kerala, where temperatures have soared to 40.4°C, making them the hottest regions in the country’s plains.

Experts say that such high temperatures are uncommon in the first two months of the year. This sudden transition from winter to summer can take a toll on the human body, making many people vulnerable to illness during this period.

How Does Weather Transition Affect Your Body?

As seasons shift from cold to warm, the sudden temperature change puts pressure on your immune system, making you prone to infections like colds, flu, and respiratory illnesses. Here’s how your body reacts to changing weather:

Weakened Immunity – The body's defense system becomes vulnerable, increasing the risk of infections.
Sinus & Joint Pressure – Fluctuating temperatures can lead to sinus congestion and joint pains.
Thickened Blood & Joint Fluids – Sudden warmth can thicken fluids in the body, causing discomfort.
Narrowed Blood Vessels – Rapid changes in temperature constrict blood vessels, leading to headaches or migraines.
Dried Mucus Membranes – The dry air causes the nasal passages to crack and become inflamed, making it easier for viruses to enter.
Pollen Allergies – Springtime triggers pollen release, affecting those with seasonal allergies.

Moreover, with certain bacteria and fungi becoming active after dormancy, people with weakened immunity are at a higher risk of sinus infections and respiratory issues.

How to Protect Yourself from Weather-Related Illnesses

If you don’t want to spend days feeling sick with a stuffy nose, sore throat, or fever, follow these simple yet effective precautions:

1. Eat Anti-Inflammatory Foods

Boost your immunity by including anti-inflammatory foods rich in antioxidants that help your body fight infections.

Leafy greens (Spinach, Kale) – Rich in Vitamin C, supports immune health.
Berries (Blueberries, Strawberries) – Packed with antioxidants.
Salmon – High in Omega-3, which reduces inflammation.
Sweet potatoes – Strengthen the immune system.
Nuts (Almonds, Walnuts, Pistachios) – Contain Vitamin E for better immunity.

2. Stay Hydrated

With rising temperatures, dehydration is a major concern. Drink plenty of water throughout the day to keep your mucus membranes moist and prevent viral infections.

Tip: If you tend to forget, set reminders on your phone to drink water every hour.

3. Maintain Proper Hygiene

Good hygiene is essential during weather changes to prevent infections.

Shower daily to remove sweat, dirt, and bacteria.
Wash hands frequently, especially before eating.
Clean under your fingernails, as germs hide there.
Avoid touching your face, especially your nose and mouth, to prevent bacteria from entering.

4. Avoid Sharing Food & Drinks

Viruses and bacteria spread faster in transitional weather. Do not share utensils, drinks, or food with others to reduce the risk of infection.

5. Exercise Regularly

Regular physical activity strengthens your immune system and helps your body fight off common seasonal illnesses.

Walk or jog for at least 30-45 minutes daily.
Studies show that active people take half as many sick days as those with sedentary lifestyles.

Final Thoughts

With unseasonal heatwaves making an early arrival in many parts of India, it's essential to prepare your body for the weather transition. By following simple health tips, including eating right, staying hydrated, maintaining hygiene, and exercising, you can stay healthy and energized during this challenging period.

As summer approaches, take extra precautions to protect yourself and your loved ones from heat-related illnesses.
