2. Keep the windows closed; if it is not possible due to the scorching heat, at least protect them with wet gauze or nets. Moisturize your house as much as possible – for example, fill your bath. Clean all the surfaces with a wet texture to remove the smut.

3. When at home, avoid using candles and incense, do not use vacuum cleaner or gas stoves, turn on your cooker hood while cooking.

4. Never smoke at home!

5. Be careful with your air conditioning systems – those taking the air from the outside can be used only if they are equipped with special filters; split conditioners are better.

6. If possible, leave the city.

7. Avoid physical exercise – they make you breathe deeper. Stop jogging in the park and leave your bike alone. If your work involves intense physical activity, ask your employer to cut your work hours.

8. Cut down the number of cigarettes you smoke daily or rather give up smoking all together until the situation improves. Avoid heavy smoking areas.

9. If you have certain breathing illnesses, consult your doctor immediately.

10. If you choose to wear a mask, make it wet. What you actually need is a special respirator.

11. Avoid big roads overloaded with smoke – rather use the Metro.

12. Drink as much as possible.

13. Eat more vegetables, drink green tea and fresh juice rather than coffee and soft drinks.
