My body didn’t stop shivering for 2 hours. After five cold plunges and no heat, even a hot shower, coffee, and a sun-baked car couldn’t warm me. It hit me: cold exposure is powerful — but incomplete.
Thanks for sharing this. Beyond the personal benefits, I believe that there could be an impact on fertility. Given that wearing briefs can affect sperm count, I'm thinking that warm jacuzzis, saunas, coupled with sub-10 deg C cold plunges would have an impact. Would be interesting to see what the scientific research shows, especially if the user is also trying for kids!
1. Men trying to conceive should avoid regular saunas and prolonged heat exposure — that’s one of the few well-established lifestyle risks to fertility.
2. Cold exposure might help in heat-related male infertility (not a magic fix, though).
3. Women can likely use sauna or cold in moderation without issue, but extreme or chronic thermal stress should be avoided during sensitive windows.
So yes — your instincts are right. If you’re trying for kids, it’s worth being strategic about heat and cold exposure. There’s still a lot to be studied in this area, especially around contrast therapy, but we already know enough to proceed with awareness.

Here is what I gathered from initial research -
1. Men trying to conceive should avoid regular saunas and prolonged heat exposure — that’s one of the few well-established lifestyle risks to fertility.
2. Cold exposure might help in heat-related male infertility (not a magic fix, though).
3. Women can likely use sauna or cold in moderation without issue, but extreme or chronic thermal stress should be avoided during sensitive windows.
So yes — your instincts are right. If you’re trying for kids, it’s worth being strategic about heat and cold exposure. There’s still a lot to be studied in this area, especially around contrast therapy, but we already know enough to proceed with awareness.
