With longer days and travel plans taking shape, summer is a season of movement. But it also brings with it a quieter, growing concern. Doctors across cities are reporting a noticeable spike in seasonal illnesses, many of them preventable. As National Dengue Day 2025 shines a light on mosquito-borne diseases, medical experts are calling attention to the broader risks of the season from food and water contamination to airborne allergies and dust-related respiratory issues.

A Thirst For Trouble : Unsafe Liquids And Unhygienic Eateries

Dr. Vinay Hosadurga, Internal Medicine Specialist at Vasavi Hospitals, explains,

"The dry season not only accelerates dehydration but also heightens the risk of infections due to increased consumption of beverages and food from unhygienic sources especially outside eating or drinking. It is common that during summer, dehydration leads people to consume more liquids like roadside fruit juices and sugarcane drinks, which may not always be prepared with clean water. This can become a source of bacterial and viral infections."

With many people on the move during summer holidays, roadside snacks and drinks become a go-to. But as Dr. Hosadurga points out, this convenience can come at a cost. Even bottled or so-called "mineral" water isn't always safe if it's used alongside contaminated ice or in food preparation.

Common Summer Illnesses : What To Watch For

Typhoid, cholera, hepatitis A and E, and food poisoning are the usual suspects during the hot months.

"Contaminated water used in snacks like pani puri or roadside dishes often causes throat irritation and gastrointestinal symptoms. This may also lead to skin reactions and rashes in sensitive individuals," Dr. Hosadurga adds.

Allergies And Air Quality : Not Just A Winter Problem

Many associate allergies with colder weather, but summer comes with its own set of triggers.

"Many think that allergies trigger in winter. In fact, summer also triggers a rise in allergic reactions and respiratory conditions, mainly due to the increase in airborne dust particles," says Dr. Vinay. "Unlike winter, where viral infections are more common, summer-induced allergies are largely caused by dry weather and suspended particulate matter in the air."

Wearing a mask, especially while commuting or travelling through dusty areas, and washing up after coming home can go a long way in reducing allergic flare-ups.

Dengue And Chikungunya : The Silent Daytime Risk

As part of the conversation around National Dengue Day, Dr. Hosadurga underlines the importance of staying vigilant about mosquito-borne illnesses, especially in urban areas where clean water stagnates in flowerpots, construction sites, and AC trays.

"These mosquitoes bite during the daytime, often from under desks or tables in homes and offices. Fumigation, use of repellents, mosquito nets, and eliminating stagnant water are essential preventive measures."

Dengue symptoms can appear mild at first-fever and joint pain but they warrant early testing and platelet monitoring.

"Dengue is not typically fatal, but delays in diagnosis can lead to complications. Early testing and monitoring platelet counts can ensure better outcomes," Dr. Hosadurga advises.

A Seasonal Reminder

National Dengue Day is a timely nudge to rethink how we interact with our environment during summer. Whether it's sipping sugarcane juice at a roadside stall or letting water collect on the balcony, small habits can have big consequences.

As travel picks up and temperatures continue to rise, a little caution can make all the difference. Staying hydrated with safe water, eating mindfully, protecting yourself from dust and bites, and not ignoring early symptoms-these simple actions can help you enjoy summer without the setbacks.
