Hi, I am a Vietnamese Pharmacist. Our country's doctors recommend that: we should have sun exposure at the time of early morning (before 9a.m) and after 3a.m. Our city's latitude (Hanoi, Vietnam) is 21.07. And I ever said to some doctors about the best time of the day for sun exposure in summer (from 10 a.m-2h p.m), but they said " You are crazy. We learned from Medical University that the middle time is dangerous for skin. I want to know that if:
– Have any public guiline of time of the day for sun exposure?
– May you have some supports for me to apply latest updates of the time in my country.
Thank you very much!
