Good day to you :) okay, yesterday i had an excellent time in a Sauna for 45 minutes at my local finess gym. SO Awesome! I sweat and i was so relaxed. I had a nice warm shower off afterward and got dressed. I was in the shower and i felt a hard beat within my ribcage and it continued like as if my heart opened up into big stretched out beats good and hard. I clutched my chest where my heart is and I felt like i was clutching my heart ! Like WOW ! and then it went away after 5 minutes or so, until i went to get my shoes on to leave my local gym and it started up again. I had my friend put his hand on my chest ON TOP of my jacket and he got concerned because he could feel my heart beating bigly and asked if I need to go to the hospital and repeated asking if I want to go to the Emergency. I said no, it s only my heart beating big. What is your opinion on what happened last night with my heart? Did my experience in the Sauna have anything to do with my Heart s stretched out beating? I am in really good health. no problems. all green lights.
