Today we're unpacking a buzzy wellness trend: cold plunging. You've probably seen the hype—ice baths, breathwork, big promises. But when it comes to female fertility, the picture is more nuanced. Cold plunging is not the superpower habit it's marketed to be, especially if you're trying to conceive.

Timing and context matter. And once we factor in menstrual cycle physiology, the story changes even more. Male fertility is a different conversation, with clearer potential benefits around temperature management for sperm. In this episode, we walk through physiology, fertility-specific research, and the real-world considerations to help you decide what's right for you.

How a woman's core body temperature shifts across the menstrual cycle

Why targeted cooling—not whole-body plunges—may support male fertility
