Morning sunlight may actually help repair your skin for the stronger sun later in the day.
In a paper by Barkley et al. ‘Infrared and Skin: Friends or Foe’ (2016), the authors discussed the benefits and the potential mechanism that morning sunlight infrared A (IR-A)- may help prime the skin’s natural protective mechanisms before UV exposure peaks around midday.
Furthermore morning light hitting your eyes activates melanopsin — a light-sensitive pathway that tells your brain, “It’s daytime!”and helps regulate your circadian rhythm, sleep-wake cycle and other biological processes.
But here’s the catch: If you wear sunglasses you block melanopsin signalling, which dysregulates your bodies ability to open your skins pores to let UV, vitamin D and other phytonutrients in resulting in an overexposure- increasing the likelihood of sunburn.
Time home message: get outside early in the morning before 10am- no sunglasses to protect your skin from excessive burning throughout the day.
Apply sunscreen when the UV is over 3, but leave your skin un-sunscreened early morning and late afternoon to get those Infrared benefits systemically.
