Increase your caffeine consumption: If you are a coffee addict with asthma, there is good news! Caffeine is a significant natural element that can help reduce asthma symptoms. Caffeine contains properties similar to theophylline, a medicinal drug used to treat various issues caused by asthma, like shortness of breath, chest tightness and wheezing. If you do not like coffee, you can have other drinks such as black or green tea, cocoa drinks, chocolate, energy drinks, and chocolate-flavoured food items. So, you have many options, even if you prefer something other than coffee.
