Elevation?

Does elevation cause issues?  I live at 300ft but over vacation at 3500 ft I seemed to have felt tighter?

I haven't noticed it -- we live at 4K and hike at 7 - 9K alot -- with out issue

I find that humidity impacts my band much more than elevation ---- makes me feel a little tight -- just like my jewelry gets tight when it is more humid.

It wouldn't surprise me. The band reacts differently to different situations. Heat and humidity make my band tighter and when I fly, all my clothes feel tighter from the air pressure etc, so just take it as another unpredictable behavior of the band. I have found that there are many of these....
Good luck!

Yes, higher elevations can make the band tighter.

We vacationed in Santa Fe (about 7,000 feet) last summer and I live in Connecticut .  I didn't notice any difference, but everyone's system reacts differently and it'spossible that you are sensitive to increased elevation.

Thank you all.  Next time I'm on vacation at an elevation for over a few days I'll have to see if this is my sensitivity.
