After experiencing intense heat for weeks with temperatures regularly rising above 30 degrees Celsius, Mumbaikars got respite from the summer weather as gusty winds and unseasonal rains hit the city late on Tuesday, May 6, and continued on May 7 and May 8.

The monsoon season in Mumbai usually begins in late June. While the surprising rainfall in May brought with it a slight dip in mercury levels, this sudden change in weather can cause many different health issues, if suitable precautions are not taken, Mumbai-based experts warn.

Health risks due to unseasonal rain

The unseasonal rains that graced Mumbai skies, followed by a sudden drop in temperature and increase in humidity levels, can create ideal conditions for spread of viral infections and other health issues.

Dr Manjusha Agarwal, senior consultant internal medicine, Gleneagles Hospital in Parel says, "Sudden weather changes may trigger viral infections, cold, flu, and respiratory issues such as cold, cough, sore throat, runny nose, congestion, stuffy nose, migraine, sinusitis, and allergic rhinitis. The rise in humidity can also worsen asthma, bronchitis, and allergies."

Heavy rains may also cause waterlogging in several parts of the city, which can lead to a rise in mosquito-borne diseases like dengue and malaria.

Apart from viral infections and respiratory issues, this weather change may also cause skin infections. "Conditions like eczema, ringworm and candidiasis become more common during unseasonal rains due to prolonged dampness, wet clothes and poor hygiene," Dr Agarwal informs.

Who is more at risk?

While anyone can be susceptible to health issues arising out of sudden weather changes, people with weak immunity, children, and the elderly are at a higher risk.

Key precautions to take

Maintaining hygiene and boosting immunity is key during such weather changes.

"Wearing weather-appropriate clothing and staying dry during unexpected rains is essential to avoid viral and skin infections," advises Dr Agarwal, adding, "It is also necessary to use mosquito repellents and avoid stagnant water near the house, and in pots, pans, or cans to prevent dengue and malaria."

Another important step to protect your health from infections due to seasonal changes is boosting immunity through a balanced diet.

Dietary changes to make to your diet

Vedika Premani, clinical dietician, Sir HN Reliance Foundation Hospital in Girgaon suggests following some nutritional guidelines to protect oneself from infections:

1. Focus on consuming fresh, seasonal fruits high in vitamin C, such as guava, oranges, amla and berries to naturally boost immunity.
2. Always wash fruits and vegetables thoroughly before eating.
3. Sip on immunity-boosting teas like ginger, herbal, and chamomile, which have anti-inflammatory properties to help fight off infections.
4. Consume superfoods like turmeric, garlic and ginger, which can help strengthen immunity.
5. Stay hydrated. Boil water before drinking to prevent chances of infections.
6. Avoid street food during this time as it might increase risk of waterborne diseases due to poor sanitation.

Apart from nutrition, healthy lifestyle practices like adequate sleep and regular exercise can help keep infections at bay.

"Those with asthma or allergies should keep medications handy and avoid exposure to allergens. Staying hygienic and cautious can help improve well-being," concludes Dr Agarwal.
