Respected sir/Madam, I am having rapid shortness in breathing since last week. While doing high intensity exercises in the morning I am unable to breathe from nose rather  breathe through mouth. Also, while having my meals I need to take long breathe . The meals which I used to finish in 10 mins nowadays it's taking almost double time to finish the same meals. I use to exercise and workout more than half an hour a day. Is high intensity exercises are suitable for me?? I don't have chest pain. Earlier, I don't had breathing problems. Is it due to sudden weather change in my area?? Please solve my issue and suggest some natural home remedy by which I can solve my issue. Thanking you
