Got sunburned in Nha Trang — can I still go to the beach or swim?

How to avoid burning again: in July 2026 a tourist who stayed on the beach from 8am to noon got burned. A participant replied that this was too long — in his view you should be in the sun only from 8 to 10am — and that sunscreen should be applied half an hour before going out in the sun, not once you are already on the beach.

Asked whether you can keep walking, swimming and lying on the beach in a thin shirt after a sunburn, a participant replied in July 2026: if you do not want a long recovery and a risk to your skin — including, in his words, skin cancer — it is better to end the beach part of your holiday. This is a participant's opinion; for a severe burn, treatment decisions belong to a doctor.

Why a thin shirt does not help: the same participant explained that the sun burns not only with ultraviolet but also with infrared radiation — essentially heat — and that heat keeps irritating the burn. He advises wearing proper clothing rather than gauzy fabric and staying off the street during peak heat, from 10am to 4pm.

Personal experience from the same reply: the participant burned his shoulder in spring, and even two months later the sun still stung it through a T-shirt. It shows that burned skin can stay sensitive for a long time.

Another tip from June 2026: go to the sea between 6 and 8am to avoid getting badly burned, and buy SPF 50 sunscreen.
