I suffer with health anxiety so worry about it allot. I have started my new job being bin man (refuse collector) and with all the walking and jogging i can get heart palpitations/flutters which seem daily and i know the hot weather doesn’t help at times either. I do worry allot and get stressed.. is it just my body being so used to being anxious? it’s frustrating and annoying when i feel it. I used to play 5 a side football but stopped because when i started to build up a sweat and my heart rate increases my heart would feel like it’s skipping beat or fluttering and then I would be super focused on it. I have had numerous ECGS and blood tests in the past and everything came back fine but i do worry about it. I am currently 30 and have noticed this with any exercise since I was like 17. I feel like it’s all related to my anxiety and stress. I feel if I didn’t feel that way often my heart wouldn’t do what it does if I exercised or where my heart rate is elevated.
