Damaoxiong began to pollen allergy at the early of April this year. It lasted almost one month. The symptoms mostly are sneezing, running nose, itchy eyes and itchy throat. Nose like a faucet running water and eyes like a rabbit, red and itchy. Those symptoms bothered me to work normally. I had to see doctor and take eye drop, nasal spray and tablets to release those allergies.

Damaoxiong almost recovery this week, however, the season of Tucson seems half month later than Phoenix. Flowers are blooming everywhere. When Damaoxiong arrived there this weekend, allergy happened again and was very seriously. It seems that Damaoxiong is very sensitive to pollen and dust right now. Spring is the lovely season of the year. Damaoxiong can not smile at flowers any more.

People usually began to allergy at 4th or 5th years after moving to US. Damaoxiong is curious why allergies happened and checked on line. It seems like immune system is an organism that fights bacteria and viruses in order to protect our bodies, however, sometimes, they respond to a false alarm and go through a number of reactions and one of these can release histamines, in turn, cause us a series of allergy symptoms.

Damaoxiong thought there are two reasons to cause us allergy. First is due to the pollen levels. US air quality is much better than China, less various particles in the air induced that pollens can travel for a long distance, and thus pollen levels in air should be higher in US, which may reach the level to affect people who are very sensitive to pollen. Second, people immunity system decreased due to less bacteria and viruses day by day. According to these two points, we may need to exercise more or go back to china to get some little illness to increase our immunity systems .
