Are we getting enough of the right kind of light?
In this Quick Hits episode, I pull out the biggest takeaways from my conversation with Gerardo "Guti" Gutierrez on sunlight, UVB, vitamin D, red light therapy, infrared light, circadian rhythm, and hormone health.
We break down why sunlight is about far more than vitamin D, how UVA and UVB affect the body differently, why people living in northern climates may get very little UVB for much of the year, and how the light we get during the day can affect sleep, mood, metabolism, and hormones.
You'll also hear why morning light, midday UVB, infrared light, and nighttime blue-light exposure all send different signals to the body, and why modern indoor living may be disrupting those natural rhythms.
In this Quick Hits episode:
- The difference between UVA, UVB, visible light, and infrared light
- Why UVB is necessary for vitamin D production in the skin
- Why sunlight and taking a vitamin D supplement are not exactly the same thing
- Why Canadians and others living in northern climates may get very little UVB during winter
- How morning sunlight supports your circadian rhythm
- Why bright artificial light at night can interfere with sleep
- The connection between sunlight, mood, metabolism, and hormone signaling
- How red and near-infrared light interact with mitochondria
- Red light therapy vs. UVB light therapy
- Why timing, wavelength, and light exposure matter more than most people realize
Guti also shares his personal experience of increasing his testosterone after making several lifestyle changes, including more sunlight, exercise, and better sleep.
