Near Infrared Sauna for Fertility: What the Research Says + Our Success Story

Starting a family later in life isn't uncommon these days, but it often comes with a host of discouraging statistics: declining egg quality, lower ovarian reserve, and increased risks for both partners. When my husband and I began planning for pregnancy in our 40s, I was determined not to approach this chapter with fear, but with intention, knowledge, and trust in the body's ability to heal and thrive.

As a chiropractor and holistic wellness provider with years of experience supporting women through the perinatal period, I knew there were powerful ways to optimize our fertility naturally—tools that support the body's internal environment rather than override it. One of the several strategies we incorporated? Near infrared (NIR) sauna therapy.

Why We Started With a 120-Day Fertility Prep Window

Research shows that it takes approximately 90 days for both eggs and sperm to mature before they're ready for ovulation and ejaculation. So instead of waiting until we were "trying" to conceive, we backtracked four months to give our bodies time to reset and rebuild: 30 days for detox and body preparation, followed by 90 days of focused preconception support.

Our Preconception Plan included:

• A 21-Day Purification to support liver function and hormonal balance
• Reducing exposure to endocrine disruptors (cleaner food, skincare, and home products)
• Stress reduction strategies, including sleep hygiene and nervous system support
• Frequent use of near infrared sauna therapy for detoxification, hormonal regulation, and enhanced cellular energy

What Is Near Infrared Sauna Therapy?

Unlike traditional dry or steam saunas, near infrared (NIR) saunas emit a specific wavelength of light that penetrates deeper into the tissues. This light is absorbed by our cells—specifically, the mitochondria within the cell—which reduces inflammation, promotes detoxification, and, particularly important when it comes to egg and sperm health, boosts energy production (ATP).
