These hand warmers can also help you get the synthetic urine to the right temperature without a microwave. Itâs also possible to use your own body heat to get the urine to the right temperature. However, this isnât the easiest way to keep the urine at the right temperature. Regardless of how you decide to heat the synthetic urine, you want to make sure it remains very close to the 96-degree mark. If itâs too warm or too cold, the urine may not provide the full effectiveness you are hoping for.
