Common cold in summer: what it means

Travel, indoor air-conditioning, crowded events and close contact can all bring people together when viruses are circulating. A summer cold may cause a runny or blocked nose, sneezing, sore throat, cough and tiredness. Air-conditioning can also dry or irritate the nose without causing an infection.

Allergies, heat exhaustion and influenza can resemble a cold but need different responses. Itchy eyes and repeated sneezing suggest an allergy pattern, while dizziness, heavy sweating, confusion or weakness in heat need urgent attention. Facial pain, earache or a worsening cough may indicate another condition.

Rest in a cool, well-ventilated place and drink fluids regularly. Saline nasal spray can ease a blocked nose; warm drinks may soothe the throat, while avoiding smoke and strong fragrances reduces irritation. Wash hands after coughing or sneezing and improve ventilation around others.

Do not assume every summer symptom is a cold. Check your temperature and pay attention to thirst, urination, alertness and breathing. Use symptom medicines according to the label, and ask a pharmacist if you have other conditions or take regular treatment.

Seek urgent care for difficult breathing, chest pain, confusion, fainting, severe dehydration, blue or grey lips, or signs of heat illness. Arrange medical advice when fever persists, symptoms worsen, facial pain becomes severe, ear pain develops or a cough is interfering with sleep and daily activity.

Ask whether your symptoms fit a cold or an allergy, how to manage congestion in air-conditioning, and which warning signs matter in the heat. Mention recent travel, outdoor exposure, regular medicines, asthma or other long-term conditions.
