Target Population General population and Vulnerable groups such as children, elderly and those with underlying medical conditions Optional interventional choices I. General Population Reduce risk from exposure to air pollutants by taking up the following measures. Avoid preferably places with high air pollution like roads with slow & heavy traffic, areas near polluting industries, construction-demolition sites. Avoid outdoor morning and late evening walk, run, jog and physical exercise. Do not open external doors and windows during morning and late evening hours, it may ventilate if necessary, between 12 p.m. to 4 p.m. in afternoon (Days with poor to severe AQI) Avoid burning biomass such as wood, coal, animal dung, kerosene. Use clean smokeless fuels (gas or electricity) for cooking and heating purposes. If using biomass, use clean cook stoves. Avoid burning of wood/ charcoal in 'Anghiti' during winters, in closed and confined condition which may be fatal due to CO and built-up CO2 Avoid use of room fresheners, it has ill effects as it consume O2 in vicinity very fast. Avoid burning firecrackers. Avoid burning in open any form of wood, leaves, crop residues, & waste. Do not smoke cigarettes, bidis and related tobacco products. Avoid burning mosquito coils and incense sticks in closed premises. Reschedule outdoor activities as per AQI, and remain indoors on days with poor to severe AQI. Practice wet mopping instead of sweeping or vacuum cleaning inside homes. If you choose to use vacuum cleaner, use those having High Efficiency Particulate Air (HEPA) filter Keep washing your eyes with running water regularly and do regular gargles with warm water Consult the nearest doctor in case of breathlessness, giddiness, cough, chest discomfort or pain, irritation in eyes (red or watery) As a "no-regret" strategy, healthy diet, with fruit and vegetables rich in antioxidants, and adequate amount of hydration by drinking water is advocated. II. Population with certain medical conditions Those with underlying medical conditions particularly chronic pulmonary or cardiovascular problems should have following additional measures Be more careful to avoid exposure to air pollution Avoid any strenuous activity and stay indoor during higher AQI levels Keep a check on exacerbations of suggestive symptoms Properly follow doctor's instructions on healthcare Keep the prescribed medications readily available Seek immediate medical advice if symptoms worsen. III. Optional choices (Face Mask, Air Purifiers, Air Conditioners) If you choose to use face mask, the disposable N95 or N99 is useful provided user instructions are followed. These masks may help provided the period of exposure is short. Masks should have proper fitting on users' mouth and nose. Ensure to replace the masks after usage as instructed. Paper masks, handkerchiefs, scarves and cloth are not effective. If you choose to use air purifier, follow manufacturers' guidelines, however it may be advised to have expert's consultation on suitability, positioning, technology selection and cleaning capacity (area coverage). Ensure to replace and clean filters as instructed. Avoid using an air purifier that works by generating ozone, as it increases pollution inside rooms. When operating air conditioners in buildings or vehicle, use in "re-circulate" mode to avoid contact with outside air.
