Short answer: not at all!
Embr Wave is powerful, but not that powerful.
If you’re not in danger of freezing or overheating, Embr Wave works great for a mild dose of relief when you need it.
If your core body temperature is actually elevated or depressed, your body will override local thermal sensations to let you know you’re in danger!
In other words, Embr Wave won't override your thermoregulatory system in extreme environmental conditions.
