Rain Flu: Causes, Symptoms, and Remedies

Rainy days bring relief from the summer heat, but they also come with an increased risk of catching seasonal illnesses like rain flu. Many people wonder, “Can rain cause flu?” or “Why do we get sick in the rain but not in the shower?” Let’s explore the science behind getting sick from rain, common symptoms, and effective remedies to keep you healthy.

Why Do We Get Sick in the Rain?

Rain itself doesn’t directly cause the flu. However, when you’re soaked in the rain for more than an hour, your body temperature drops, weakening your immune system. This makes it easier for viruses and bacteria to attack.

Here are some reasons:

• Temperature changes: Sudden cooling from being wet can stress the body.
• Weakened immunity: The body diverts energy to regulate temperature, leaving less to fight germs.
• Exposure to pathogens: Damp clothes and wet hair create an environment where microbes thrive.

Interestingly, a hot shower doesn’t make you sick because the water is warm and doesn’t lower your body temperature drastically.

Rain Flu and Weather Changes

Many people report flu when weather changes, especially during the rainy season. The humidity and temperature shifts encourage the spread of viruses.

Common causes of rain flu include:

Viral infections like influenza or common cold viruses.

Rain Fever: Symptoms to Watch Out For

Sometimes, people refer to flu during monsoons as rain fever. It can have symptoms similar to seasonal flu but might also be mistaken for other infections like dengue or malaria.

Common rain fever symptoms include:

• Fever and chills
• Runny or blocked nose
• Sore throat and cough
• Fatigue and body aches
• Mild headache
• In some cases, skin rashes (if due to allergic reactions or infections)

If symptoms persist for more than three days or worsen, consult a doctor immediately to rule out serious illnesses.

Side Effects of Getting Wet in Rain

Getting drenched once in a while may seem harmless, but repeated or prolonged exposure to rainwater can cause:

Respiratory infections (cold, bronchitis, pneumonia)

Prolonged exposure to polluted or acid rain may also irritate the skin and eyes, leading to additional discomfort. 

Why Does Getting Wet in Rain Cause Fever?

The body maintains a steady internal temperature. When you’re drenched and your clothes cling to your skin, heat escapes rapidly. This sudden cooling can disrupt immune function, giving viruses a chance to multiply. The resulting illness is often called rain viral fever.

Rain Fever Remedies and Prevention

Home Remedies

• Warm fluids: Drink herbal teas, soups, or warm water to maintain body heat.
• Steam inhalation: Helps clear nasal congestion.
• Rest: Adequate sleep supports recovery.
• Ginger and honey: Natural anti-inflammatory and antimicrobial properties.

Medical Care

• Visit a healthcare provider if you have persistent fever, difficulty breathing, or chest pain.
• Take prescribed antiviral or antibiotic medicines if required.

Prevention Tips

• Carry an umbrella or raincoat during the rainy season.
• Change into dry clothes immediately after getting wet.
• Boost immunity with a balanced diet rich in Vitamin C and zinc.
• Avoid wading through flooded areas to prevent infections.

When to Seek Medical Help

If you experience high fever, breathlessness, severe cough, or symptoms resembling dengue or malaria, consult Vydehi Hospital’s specialists for accurate diagnosis and timely treatment. Early intervention can prevent complications.

Key Takeaway

While rain brings joy, it can also invite illnesses like rain flu if you’re not careful. Understanding the causes, symptoms, and remedies can help you enjoy the season while staying healthy. Protect yourself, stay warm, and prioritise your immunity during the rainy season.
