What Cold Exposure Does to Hormones, Stress, and Fertility

Summary • Sarah Kleiner Wellness • ~75 minutes

⚡ TL;DR

Sarah Kleiner shares her personal journey from failed IVF rounds to natural conception at 41 through understanding circadian biology, cold exposure, and metabolic flexibility. Key insight: cold plunging boosts fertility hormones but should be paused around ovulation to avoid immune system interference with embryo implantation. Strict carnivore/keto isn't optimal for all women—a seasonal, bio-individual approach often works better for metabolism and fertility.

You need to understand leptin, circadian biology, quantum biology, and how your mitochondria work. These are going to be the keys for you in getting and staying pregnant.

🎯 Key Takeaways

1

Time cold exposure around your cycle: Cold plunge freely from cycle day 1 through ovulation, then pause for 3-4 days to allow potential implantation without immune interference.

2

Strict diets may backfire: Long-term carnivore or keto can cause metabolic downregulation in women, especially those trying to conceive. A seasonal, flexible approach often yields better results.

3

Mitochondria are fertility's foundation: Egg and sperm quality depend on mitochondrial health. Address circadian biology, leptin, and metabolic function before expensive interventions.

4

Age is not the barrier you think: Sarah's oldest client conceived naturally at 47. Focus on metabolic restoration rather than accepting "geriatric" labels.

5

Bio-individuality trumps protocols: What works beautifully for one person can be disastrous for another. Understand your own haplotype, genetics, and metabolic needs.
