Hello,
Welcome to HCM,
The symptoms are may be due to
allergy,it may be due to exposure to the allergens.
Exposure to the irritants will leads to development of symptoms.
I would suggest you to
Wash bed sheets weekly in hot water.
Always bathe and wash hair before bedtime
Do not hang clothes outside to dry where they can trap pollens.
Wear a filter mask when mowing or working outdoors.
Avoid peak times for pollen exposure
Keep windows and car windows closed
Check bathrooms and other damp areas in your home frequently for mold and mildew, and remove visible mold with nontoxic cleaners.
Keep pets out of the bedroom and off of furniture.
These are some of the remedies which will help to prevent you from getting allergic symptoms.
Thank you.
