During periods of high temperatures, many people may experience shortness of breath and chest tightness, which often become more pronounced during outdoor activities or in stuffy environments.

According to Master, Doctor Nguyen Van Ngan, Head of the Respiratory Department at Tam Anh General Hospital Hanoi, hot weather increases air pollution, disperses dust and smoke, irritates the airway lining, and reduces the lungs' protective capacity. Dehydration also thickens secretions, making them difficult to expel, and increases the risk of infection, especially in individuals with chronic lung diseases. Proactive adjustments to daily habits can protect the respiratory system during summer.

Maintain appropriate physical activity

Regular exercise improves lung function and enhances cardiovascular endurance. Activities such as walking, cycling, swimming, or light jogging are beneficial for the respiratory system.

During summer, avoid outdoor exercise when temperatures are high. Prioritize early mornings or late afternoons to minimize the impact of the heat. Before exercising outdoors, check the air quality index (AQI) using apps like AirVisual. When the AQI is above 100, individuals with respiratory conditions should exercise indoors. Those with chronic lung diseases should consult a doctor to choose suitable exercise intensity and forms.

Use air conditioning correctly

Air conditioning effectively reduces heat but can also dry out the air if not used properly. Room temperature should be kept moderate, avoiding excessively low settings compared to the outdoor environment. Do not direct cold air currents directly at your body, especially towards the face and respiratory tract.

Before going out into the sun, wear light clothing, a hat, and carry water. To avoid heat shock when transitioning from an air-conditioned room to the outdoors, pause for a few minutes in an intermediate area (such as a shaded hallway or porch) to allow your body to gradually adapt to the new temperature. Similarly, after coming in from the sun, let your body adjust to room temperature before turning on the air conditioner.

Maintain a healthy living environment

Indoor air needs to be clean and well-ventilated. Regular air conditioner cleaning, house tidying, and limiting dust and mold help reduce the risk of respiratory infections. Using air purifiers or exhaust fans can improve air quality in enclosed spaces, particularly in urban areas with high pollution levels.

Avoid factors harmful to lungs

Smoking and inhaling secondhand smoke damage the airways, making the lungs more susceptible to inflammation in adverse weather conditions. Limit exposure to polluted environments, smoke, and dust, especially on intensely hot days when pollution levels tend to rise.

Regular health monitoring

Regular health check-ups help detect respiratory issues early and effectively manage existing conditions. Individuals with chronic lung diseases should adhere to their treatment plans and follow scheduled re-examinations, which are crucial for preventing exacerbations and maintaining stable respiratory function.

Doctor Ngan advises that if symptoms such as increased shortness of breath, persistent cough, thick phlegm, or fever appear, patients should seek medical attention for examination.
