How Hot Do Hand Warmers Get And Will They Overheat Urine?

Hand warmers are a practical best practice when you’re attempting to keep your urine warm enough to pass a piss test when using fake urine.

Because, although it isn’t at all impossible to keep your urine temperature within the accepted range using your own spare body temperature alone, it’s simply not as reliable.

And with hand warmers being dirt cheap and all, most people will agree that, why not.. After all, you really don’t want to fail your drug test on a temperature error (one of the most common ways people fail when substituting pee, by the way).

But even when using hand warmers as a precaution, some issues can arise.

Especially when new at this stuff (perhaps it’s your first time substituting urine to pass a test), questions are common, and these specific ones happen to be “popular” ones.

So let’s address them, shall we?

The straightforward answer is that it varies, but that’s not a very satisfying one, is it?

It depends on the specific brand and product more than anything, although obviously they will mostly stay within a range that’s not too far off from your body temperature. You wouldn’t want to be warming your hands or hiking clothes to 250 °F, so.. it should stay warm but comfortably so, not excessively so.

Hence, most hand warmer brands will do as long as they don’t explicitly state they’re of an irregularly hot variety.

That said, for our purposes it’s sort of the wrong question to ask to begin with. The question you should be asking here is rather, at what temperature do hand warmers keep your urine? In the end, that’s what matters, and it differs a bit from how hot they get themselves.

Building on my previous point on hand warmers naturally being adapted to the temperature of your body, they’re all gonna help keep your fake urine within or at least close to your desired temperature. But since that answer isn’t ideal here in any way, I’m gonna include some actionable tips to get it right at the end of this post as well, so just hang tight!

But first:

Will Hand Warmers Overheat Urine?

It’s a good question, and the answer is good to keep in mind before mindlessly writing off a future piss test as a done deal since you’ve got the urine and hand warmers covered already.

The answer is that yes, sometimes they might. I’ve heard and read about it happening on several occasions, with the commonality being that it’s not by a lot. The urine samples would be slightly too hot, hovering between 100 and 104 °F, but that’s enough for it to not be accepted.

So how do you avoid this issue from happening and nail the temperature down perfectly for your test, even as a first-timer?

To Not Screw The Urine Sample Temperature Up For Your Drug Test – Practice

I’ll keep this as simple and to the point as I can:

Urine temperature strips
Without a way to gauge your urine sample’s temperature, you won’t get much useful information out of your practice.

Especially if it’s your first time and nerves are at play, nothing’s gonna help you more than some good old practice so that you know what to expect and won’t feel like a first-timer any longer.

  • How to practice? Get a package of good but cheap hand warmers from Amazon along with some urine temperature strips (these are crucial). An accurate thermometer for liquids will work just as well, probably even better.
  • Attach the hand warmer to a container of urine or water (rubber bands are good for this, either the one you intend to use during your actual piss test, or a similar one.
  • It’s gonna be close to your body and get some heating benefits from that during your actual test, so figure out where you plan to hide it for the real test, and keep it in the same spot when practicing too as to not skew the results.
  • If it seems to get too hot, you can adjust how close to your body (skin contact, no skin contact, etc) it gets, and also put something in between the heater and the bottle, be it paper, cloth etc, to slightly reduce its heating potential.
  • If it doesn’t seem to get hot enough, on the other hand, do the opposite; more skin contact, perhaps an additional heater.
  • A good tip is also to time how long it takes for your urine to reach the desired temperature when heating, and how fast the temperature drops if you remove the heating (this will depend on the surrounding room temperature), to know how much time you got to turn it in to the test administrator and so on.

The accepted range for urine samples fall between 90 and 100 °F, or roughly 32 to 38 °C. You wanna aim for somewhere in the middle, 96 °F being a good number and the upper range of normal human pee leaving the body.

Another way to solve a lot of your temperature issues right away would be just going with my personal favorite brand of synthetic urine, Sub Solution. Aside from being extremely reliable, it’s the only one I know of that includes a heating powder to allow for instant adjustment of the temperature during your test, should it fall below the range.

Either way though, if you’re substituting urine for your urinalysis in the first place, you’ll want to make sure to check out my comprehensive guide on the topic, since there are many things aside from the temperature one can get wrong if not properly prepared.
