However, if you still feel sick, you may need to take an “anti-allergen pill that can be used for mild cases, and injections and oxygen can be used for severe cases,” Dr. Bindumathi said.


-Finding the cause and eliminating it or containing it in some way to prevent odors from occurring are the best ways to manage indoor odors.

– Opening windows and turning on fans, adequate air conditioning helps improve fresh air ventilation, which will help reduce the odor until the source is removed.

-To prevent inhalation of dangerous substances in public places, it is recommended to use a mask when going outside.

Dr Bindumathi warned: “Some people choose to use air fresheners or scented candles to bring scents into their indoor space. By dispersing multiple chemicals into the indoor air, these scented items only cover or hide other scents. They can irritate sensitive people or trigger allergic reactions.”
