Are sunscreens safe?
There is now serious review on certain chemical approaches we have taken to block the sun.
A recent JAMA study shows that common chemical sunscreens (like oxybenzone, avobenzone, and octocrylene) are absorbed into the bloodstream at levels well above FDA safety thresholds—even after just one day of use.
This adds to 2019 research raising the same red flags: we urgently need to review the long-term safety of chemical sunscreens.
Safer sun strategies that build better relationships with the sun include:
Get morning sunlight (before 10 a.m.) for natural vitamin D and circadian health
Use mineral-based sunscreens (zinc oxide, titanium dioxide)—not absorbed into your system
Sunlight exposure is one of the fundamental pillars of human health.
Should we fear the sun?
