R.H.
10 minutes of sun a day is all we need to get vitamin D. With the rates of skin cancer these days, the benefits of sunsceen greatly outway the risks. Buy a natural sunscreen with either titanium dioxide or zinc oxide, both are naturally occuring minerals that provide a full spectrum physical protetion against the harmful UV rays. I stay away from chemical sunscreens especially pasol 1789 or avobenzone. I haven't found a natural insect repellent that actually works but I use them anyway, and suffer through the mosquito bites. Lavender on insect bites helps too!
Enjoy the summer:)
