More Than Just Vitamin D
Sunlight is often discussed in the context of vitamin D, but its benefits go much deeper. In a conversation between Dr. Roger Seheult and Dr. Andrew Huberman, they explain how daily exposure to natural sunlight, especially red and infrared light, can support mitochondrial health, immunity, mood, and long-term wellness.
The Original Red Light Therapy
Dr. Seheult describes getting outside for sunlight as one of the easiest “low-hanging fruit” habits we can use to improve our health. Instead of relying only on expensive red light therapy devices, he points out that the sun is the original and most natural form of red light therapy. It provides a broad spectrum of light, including infrared wavelengths that may help support cellular energy production and overall function.
15 to 20 Minutes Can Make a Difference
The good news is that you do not need to spend hours outside. Research suggests that many of the benefits begin to taper off after about 15 to 20 minutes of exposure. That means a short walk, a few minutes outside in the morning, or even eating lunch outdoors can be enough to make a meaningful difference.
Why Winter Sunlight Matters
This becomes especially important during the winter months. Dr. Seheult and Dr. Huberman discuss how many natural causes of death, including influenza, heart disease, kidney disease, and Alzheimer’s, tend to rise shortly after the darkest period of the year. At the same time, modern lifestyles keep many people indoors for most of the day. Some people commute before sunrise, work inside all day, and return home after sunset, going days or even weeks without consistent sunlight exposure.
Artificial Red Light: Use With Caution
For people living in darker winter climates, artificial red or infrared light may be helpful, but it should be used carefully. Dr. Seheult emphasizes that more is not always better. Too much intensity from artificial devices can potentially create negative effects, so low-energy light that mimics natural sunlight is the safer approach.
The Simple Takeaway
The biggest takeaway is simple: get outside daily when possible. Even 15 minutes of natural sunlight can be a powerful habit for supporting energy, immune health, mood, and longevity. It is free, accessible, and one of the simplest ways to reconnect with an important biological signal our bodies are designed to receive.
Get After It!!
