So maybe sunlight causes a nervous stimulation of the cells in the nose. If it does then this might result in swelling in the mucus membrane of the nose. I think that is wishful thinking. Sometimes they are never allergic again. Girls seem to begin their allergy about puberty and they may have fewer allergies when their hormones change later in life, around menopause.
Older people get allergic and tend to get increasingly allergic as they get older.
That is people in their 60's and 70's. They all have exactly the same ring structure and differ only in a single side-chain. Cortisol is one of pour least abundant and most readily depleted hormones. If you need estrogen then nature makes even less cortisol trying to keep you fertile. So you gain weight, have more allergies, less energy and handle stress less well.
