Does changing the session duration change the way the cooling or warming waveforms feel?Updated a month ago

Changing the duration of a session also changes how the waves feel, and also may impact how your Wave performs. 

Shorter sessions have shorter rest periods in between pulses and sharper temperature changes. These waves can feel more intense because of the faster pattern. You may find shorter sessions work better when you need a quick but strong blast of cooling or warming, like for a sudden hot flash. These sessions make your Wave work hard for a short amount of time, like a sprint, and may be more likely to cause overheating if you run several back to back.

Longer sessions have longer rest periods in between pulses, and their waves feel gentler and more sustained. These waves can feel more relaxing and soothing. You may find longer sessions work better when you want something softer and less distracting, to keep you comfortable in the background. These sessions are more like a marathon for your Wave. They're less likely to cause overheating but will use a lot of power, especially for 7- to 9-hour All Night sessions.

Shorter durations aren't "better" or "stronger" than longer durations—they're just different, and your body may respond better to one or the other depending on the situation. Experiment to find out what you like best!
