This is because when the allergy is bad, the regular body thermostat doesn't work well. Instead of warming up after getting out of bed by circulation, the body coughs and sneezes as part of the warming up mechanism. With allergy is important to avoid getting chilled, especially in a movie, this will bring on symptoms. The plants pollinate about 5 AM and 5PM, so it is important to sleep with the windows shut to avoid the 5 AM pollen, and to drive in the late afternoon with the car windows closed. This is because these spices add to the histamine already in your body which makes the allergy symptoms.
Today there are some excellent antihistamines available over the counter.
I would start with Chlortrimeton. The problem is that everyone reacts differently to these pills. Some people feel drowsy at a small dose. There are other antihistamines that have less sedation for most people such as Seldane or Claritin. On prescription, there are several steroid nasal sprays, such as Vancenase or Flonase.
