Wave sensation refers to how quickly your Embr Wave will ramp up to its temperature setpoint every time a wave comes on. For example, if you have your device set to +10 degrees, each pulse of warming you feel during your session will start at 0 and then warm up to +10 degrees at a controlled speed.
Soothing waves will go from 0 to +10 degrees at a slower, gentler speed. Each wave will feel softer but more sustained.
Energizing waves will go from 0 to +10 degrees at a faster, sharper speed. Each wave will feel more intense but shorter.
