It’s got to be uncomfortably cold but safe. There is no specific temperature for every person.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Just cold enough to be uncomfortable is a good place to start. So for some of you that's going to be 60 degrees, for some of you that's going to be 55 degrees, for some of you it's going to be high thirties, right? Depends on how cold adapted you are, and people vary in terms of how well they tolerate the cold.
So for me, the typical temperature, if you just want me to throw one out there, is somewhere between 45 and 50 degrees.
