Does being out however briefly in severe cold have an adverse effect w

I have Apical HCM (non-obstructive) and I don't find the cold causes me any problems, other than I hate it and try not to be out more than I need to. It is the heat that causes me problems.

@emo44 Perhaps this is a question for your doctor. Coughing and shortness of breath can be a sign that your body is unhappy out there.

Hi @stayhealthy2 . I mentioned in one of my earliest posts that I live in one of those places where the air hurts your face in winter. A couple weeks ago our actual temperature was close to -20F, but with the wind it was apparently close to -58F. Yes, I'm a tough Canadian but no, I didn't go out to play in the snow. I have oHCM, now controlled by Camzyos. I don't detect any cold-related issues, but pre-Camzyos, and pre-diagnosis, I did have some reactions to the winter. I'm not really sure though that it was the cold per se. When I went out in the cold and snow, I would wear big, heavy winter boots and that would cause my breathlessness and all of the other symptoms to pile on in a most unpleasant way, especially if I was having to slog through snow - even just a couple inches of the stuff. So I'm not sure if it was the cold itself or just the extra load of the heavy boots and the resistance of walking through snow. Not sure if that's of any help. But don't recommend ANYONE going out at and effective -58F, HCM or not! Be well, stay warm.

I am not certain why you are suggesting I talk to my doctor about coughing and shortness of breath since I don't have and didn't mention in my post. I said that extreme heat in the summer bothers me. This is because of my afib with rvr. It is under control with medication but heat can be a trigger so I limit my time outdoors to a very early morning walk in the heat of the summer.

15+ years with HOCM and 3+ years on Camzyos. No noticable affects of cold weather per say. However, we know symptoms and hydration are linked. Atmospheric conditions of winter weather include extended periods of low humidity. So, six glasses of WATER per day, preferably 1 or 2 before morning coffee. We are all different, but our heart health reaction to low hydration is probably more universal than cold temps.
Be careful out there!

@emo44 I am not certain, either! Somehow my comment was addressed to you rather than the person who commented on those symptoms which they were experiencing. Sorry about that. Yes, heat, especially with humidity is something we need to take seriously, I avoid it, too. Now, it is extreme cold that is bothersome. I have been walking at the mall, on the treadmill at the gym (both boring). I once suggested in a discussion about walking when it's uncomfortable outdoors to also consider big box stores. Up and down the many aisles, around the perimeter, etc. No birds to listen to, flower gardens to admire, but the exercise gets done.
