Is it normal to have a drastically high heart-rate after a hot bath?

I noticed a weird pattern for me whenever i take a hot bath. It starts when i decide to get off and leave the bathtub. First thing happens is my heart-rate. According to my fitbit tracker, my average is about 60 beats per minute but it goes all the way up to 160 right after a hot bathtub. I also feel dizzy and i can hardly find my way out of the bathroom. My way of dealing with this is to lay down on bed and close my eyes for 5-10 minutes till it wears off. Is this something of a serious concern or is it kind of normal? I don't have any health issues.

Your breathing affects your heart beats rhythm.  Interrupted respiration, not getting enough oxygen-as in a sinus blockage-can affect the heart, causing it to palpitate with quite uncomfortable force.  OK-no sinus condition?  Any internal blockage in the respiratory/circulatory system triggers a speeded up heart response.  Have both checked including ENT for esophagus and tonsils.  It's probably nothing that serious.  Good luck.

160 is rather high, but I suppose not out of the realm of possibility.  When you lay in a hot bath, your heart will begin to beat faster in a futile attempt to cool your body down.  I would say what you're experiencing is a common (although on the high end) reaction to being immersed in hot water.  Personally, I hate baths.  It's like you're sitting in a stew pot of your own filth.
