A change in altitude, especially if you travel to an area of high altitude for a few days, can influence your heart rate, breathing rate, and temperature.

As these are some of the physiological parameters that Ava measures, traveling to and staying in an area of high altitude could affect those data points which in turn may alter the prediction of your fertile window and ovulation date.

In this scenario, we would suggest not wearing your Ava while you’re in an area of high altitude and to resume wearing your Ava upon returning to lower altitudes.
