DP has hay fever. he hates cold weather, will only go on holiday in the sun but hay fever season arrives and all the doors and windows must be shut and he spends all his time off work in a dark room. I eant to fling open the windows and let the air in, have the patio doors open and relax in the sun.
What can he do to help the hay fever? Is there anything to be said for remedies like local honey or are they just woo?
