If you don’t want to take medication, the best way of avoiding allergies is, avoiding allergens. In normal, day-to-day life, it may not be possible. For example, the seasonal flu is something in the air. You cannot close your doors and windows and remain inside all the time. Similarly, if you need to visit family and friends, or even sit in a park, furry animals are everywhere. You can wear a mask. An N95 mask is supposed to block 95% of small particles. Some people have also tried getting their bodies accustomed to allergens. For example, if someone is allergic to eggs, the person first starts rubbing the egg on the skin. Then, after a few weeks, he or she starts consuming very small portions of the egg. It hasn’t scientifically been proven whether these techniques actually work or not.
