Stuck in a Fertility Winter? Red Light is the Key to Your Spring
How Light Signals Your Body It's Time to Come out of Hibernation and Reproduce
Imagine your body like a lush, green tree on a bright spring morning. Each branch hums with vitality, producing the energy needed to flourish, grow, and reproduce. Now think about what happens when that tree is exposed to an unusually long winter. The warm sunlight fades, the green leaves change color and are scattered in the wind. The tree has the intelligence to shut down into survival mode, conserving its energy just to endure the cold and lack of sunlight.
This is what happens to your reproductive system when it’s deprived of appropriate light.
Different wavelengths of light at different times of the day either turn your fertility ON (red/NIR/UV) or off (blue light in evenings).
Sunlight is so much more than just warmth on your skin —it’s a critical signal to your cells, telling them that it’s time to grow and reproduce. Without it, your body can stay stuck in a “permanent winter,” leaving you without the hormonal and cellular processes needed for reproduction. The good news? Just as the first rays of spring sunshine bring those trees and plants back to life, the right kind of light can bring your reproductive system out of its temporary hibernation caused by our modern lifestyles.
The Role of Light in Fertility
Light doesn’t just set your mood—it sets the pace for nearly every system in your body. Millions of years ago our ancient ancestors spent most of their time outdoors, hunting/gathering in natural light that regulated their hormones, energy levels, and fertility. Today, we spend most of our time indoors, under artificial lights that don’t provide the full spectrum of energy our cells need.
Your reproductive system is particularly sensitive to light signals. Here's why:
Melatonin’s Protective Role: Melatonin, often known as the “sleep hormone,” also plays a key role in reproductive health by reducing oxidative stress. Sunlight exposure during the day, especially in the morning, ensures that melatonin production is high at night when your body is repairing itself. Without enough natural light, melatonin’s rhythm is disrupted, leaving eggs more vulnerable to damage. At night melatonin is released from the pineal gland in the brain however most people don't know that during the day our mitochondria also produce melatonin. Mitochondria needs energy from light to make that melatonin. Your mitochondria LOVES sunlight and red light devices.
Leptin and Fertility: Leptin, is better known as a hormone that tells your brain when you feel full. So it makes sense that it also tells your brain whether you have enough energy to reproduce. Leptin also relies on appropriate light signals. It's like a messenger that tells your reproductive system, “Conditions are perfect—let’s thrive!” Without the right light, leptin’s message of "let's make a baby" doesn't get through, so again your body prioritizes survival over reproduction - just like that tree shedding its leaves to conserve energy in winter.
Pregnenolone and Sex Hormones: Sunlight - including UV light and red and near-infrared wavelengths, supports mitochondrial function, which is critical for producing pregnenolone in the adrenal glands—this “mother hormone” that kickstarts the creation of sex hormones like estrogen and progesterone. Without sunlight, the hormonal symphony necessary for reproduction becomes dysreglulated.
The Endless Winter: What Happens When Light Is Missing
When your body doesn’t get enough sunlight, it’s like living in an unusually long winter. The signals that say “spring is here!” never reach your cells. Energy production slows, hormones are out of balance and your reproductive system goes into hibernation mode.
Over time, the lack of correct light begins to affect:
Egg Quality and Ovulation: Without the protective effects of melatonin and the hormone-regulating power of leptin, ovulation may become irregular, and egg quality can decline.
Hormonal Imbalances: The body may struggle to produce key sex hormones like estrogen and progesterone, further disrupting fertility.
Energy Reserves: Your mitochondria—tiny powerhouses in your cells—become less efficient, leaving your body without the energy it needs to support a pregnancy.

Bringing Back the Light: Why Red Light Therapy is Spring for Your Cells
Red light therapy can provide a concentrated dose of specific wavelengths also found in sunlight, which your cells are deprived of. Unlike artificial indoor lighting, red and near-infrared light penetrate deeply into your tissues, reaching your mitochondria and providing the energy signal they need to function optimally.
Here’s how red light therapy brings your body out of “winter”:
Restoring Cellular Energy: Red light stimulates your mitochondria to produce ATP—the energy currency your cells need to carry out essential functions, including hormone production and egg maturation.
Balancing Hormones: By supporting melatonin production at night and reducing cortisol (the stress hormone), red light therapy helps restore hormonal balance, ensuring your body gets the signal that it’s safe to reproduce.
Enhancing Egg Quality: The anti-inflammatory effects of red light reduce oxidative stress, creating a healthier environment for your eggs and reproductive organs.
Resetting Your Internal Clock: Red light especially early in the day helps regulate your circadian rhythms, synchronizing the body’s processes and reinforcing the message: “The season of growth is here.”
Red light therapy acts as that spring sunshine, waking your cells and encouraging them to bloom into their full potential.
Bringing Spring to Your Body
It’s easy to overlook the importance of sunlight in modern life, but your body hasn’t forgotten. Whether it’s getting outside to soak in the morning sun or using red light therapy to give your cells the boost they need, bringing light back into your life is like opening the door to spring. I’ve found that the more inflammation/oxidative stress a woman’s body has is associated with noticeable results more quickly. Your cells have been red light-starved and blue light saturated for quite some time.
A quick note about artifical light: Blue light exposure from home lighting, phones etc at inappropriate times (evenings) is like an artificial frost in the middle of your spring, it confuses your body into thinking it’s still winter. Just as frost can damage tender young leaves on a tree, blue light disrupts the delicate balance of your reproductive hormones. It suppresses melatonin—the “gardener” that protects and nurtures your eggs—and sends mixed signals to your body about the season, delaying the growth and vitality needed for reproduction. To thrive, your "fertility tree" needs the warmth and rhythm of natural light, not the icy interference of artificial blue light.
It’s time to say goodbye to your reproductive 'winter'. Let's get your body ready to thrive, grow, and create. By giving it the light it craves, you’re giving it permission to move forward into the season of life and renewal. Because every tree deserves to bloom, and so do you.
