Sunscreen has its own side effects
Protecting yourself from excessive sun exposure is important. The operative word here is "excessive." The idea you are promoting that you not leave your home unless you "slop on sunscreen" is contributing to a growing epidemic of vitamin D deficiency, especially in the northern two thirds of the country. Among the definitions of "slop" Webster lists: "liquid refuse." Studies are showing that some of the chemicals in the products that you suggest to "slop on" may be contributing to skin cancer. Vitamin D is essential for: absorption of other nutrients, heart function, prevention of cancer, thyroid function, enhancing immunity. Bare skin exposure to the sun for 15-20 minutes, three times per week is the best way to get your vitamin D3.
Better ideas to protect from excessive exposure: "Seek shade, Slip on a covering, Slap on a hat."
