Though often associated with colder months, cough and cold-related symptoms are not uncommon during summer—especially for individuals exposed to air conditioning, fluctuating temperatures, and common viral infections. Physicians note that the combination of environmental factors and lifestyle habits can irritate the respiratory tract and trigger persistent coughing, even during the hottest days of the year.

According to Dr. Nikhil Verma, a pulmonologist based in Delhi, “The abrupt shift from high outdoor temperatures to cool, dry indoor air—especially from air conditioners—can dry out the respiratory passages and reduce the natural protective lining, making the throat more sensitive and prone to irritation.”

Prevention: Managing Indoor Environments and Habits

Experts recommend simple yet effective steps to reduce the risk of developing a summer cough. One of the primary preventive measures is regulating indoor temperatures. Keeping air conditioners at moderate settings (around 24–26°C) and ensuring adequate humidity in the room can help prevent the drying of airways.

Direct exposure to cold air from AC vents or coolers should also be avoided. “Sleeping under a direct draft of cold air or sitting too close to a cooling unit can cause throat and sinus irritation,” warns Dr. Verma.

It is also advisable to stay well-hydrated throughout the day. Warm fluids such as herbal teas, turmeric milk, and warm water can soothe the throat and help maintain mucosal moisture. Individuals prone to respiratory sensitivity should avoid sudden temperature changes, cold beverages, and ice creams, especially after prolonged sun exposure.

Treatment: Timely Care for Soothing Symptoms

For those already experiencing cough, the treatment generally depends on the underlying cause—whether it is viral, allergic, or irritant-induced. Most cases are mild and self-limiting but may last for a week or two.

Dr. Shalini Gupta, a general physician from Lucknow, recommends saltwater gargles, steam inhalation, and the use of honey-based cough syrups or lozenges to ease throat irritation. “Over-the-counter antihistamines may help if allergies are involved, but persistent or worsening symptoms should be evaluated by a healthcare provider,” she says.

In cases of a dry, hacking cough that disturbs sleep, physicians may prescribe a bronchodilator or antitussive after assessing lung function. For patients with underlying asthma or allergic rhinitis, inhalers and anti-allergy medications may be necessary to manage flare-ups during the summer.

Avoiding dusty environments, using air purifiers at home, and practicing breathing exercises can further aid recovery and prevent recurrence.

When to Seek Medical Help

While most summer coughs are harmless, certain warning signs should not be ignored. If the cough lasts more than two weeks, is accompanied by fever, breathlessness, or produces discolored phlegm, medical evaluation is essential to rule out bacterial infections or other respiratory conditions.

Ultimately, maintaining a balance between comfort and caution is key during summer. With a few lifestyle adjustments and timely treatment, summer coughs can be effectively prevented and managed—ensuring a healthier, more comfortable season.
