My sister describes feeling a shortness of breath and quicker heartbeat in a hot bath. with covid19 we havent been able to access properly if this is just with water or if similar temperature weather is the same. she doesnt like showers. any ideas?

Hot tub/baths speed up the heart but should nor make a normal person get SOB unless she gets anxious when her heart speeds up. Also getting hot increases respiratory rate to help cool. Try different temp baths to test. Keep a diary and then get back with us in a month or share with ur Dr.

If the shortness of breath doesn't resolve with cooler shower water, please see your PCP. Shortness of breath may be associated with cardiopulmonary conditions.
