Rapid Breathing
Look out for rapid breathing. Since the lungs are constricted due to the inflammation caused by allergic asthma, you need to get in more oxygen to keep the body operating as usual. This significantly increases the respiration rate. You can check it by placing the palm over the chest and count the number of times when your chest falls and rises in a few minutes. Typically, the respiratory rate of a normal person should be from 12 to 20 breaths in one minute. If this number goes up to 20 or even 30 breaths each minute, then it might be a sign of allergic asthma. [4]
