Health risk of Air pollution for travellers in Nepal

Health risk of Air pollution for travelers in Nepal

Air Pollution
Outdoor air pollution (a mix of chemicals, particulate matter, and biological materials that react with each other) contributes to breathing problems, chronic diseases, increased hospitalization, and premature mortality.

Risk: No matter where you travel, you will not be able to escape air pollution since cities and rural areas worldwide are affected by air pollution. Exposure and concentration of pollutants can adversely affect your health. When planning your trip, consider your health status, age, destination, length of trip and season to help you mitigate the effects of air pollution.

Symptoms: Short term symptoms resulting from exposure to air pollution include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, headaches, nausea, and upper respiratory infections (bronchitis and pneumonia). It also exacerbates asthma and emphysema. Long term effects include lung cancer, cardiovascular disease, chronic respiratory illness, and developing allergies. Air pollution is also associated with heart attacks and strokes.

Prevention: Comply with air pollution advisories (ask around and observe what locals are doing) and avoid strenuous activity. If you have asthma or chronic obstructive pulmonary disease (COPD), carry an inhaler, antibiotic, and oral steroid (consult your doctor to see what is best for you). It is recommended that older travellers get a physical exam that includes a stress and lung capacity test prior to departure. Newborns and young children should minimize exposure as much as possible or consider not travelling to areas with poor air quality. Ask your medical practitioner if a face mask is advisable for you.

For city and country air pollution levels, see the World Health Organization.
Nepal reports very high concentrations of particulate matter (PM10 – particles with an aerodynamic diameter smaller than 10 µm) contributing to low air quality.
