Is it true that the sun by the sea is more poisonous than other places in summer?

Because the seaside environment is very different from the inland, it can burn us more. When swimming, the weather at the seaside is usually good, with few clouds and no vegetation.

People have little shade and don't wear much clothes.

Direct exposure to strong ultraviolet sunlight. More importantly, the sea and the beach can reflect a lot of sunlight, forming diffuse reflection.

Make people accept more light, wider area and longer time. Because of swimming, people's skin will wrinkle, their pores will open and they will absorb more ultraviolet rays.

The dust content in the air is very low. Sea water does not raise dust, but absorbs a lot of dust. Due to the temperature difference effect during the day, the wind blowing from the ocean to the land will further strengthen this effect.

The shielding effect of dust on ultraviolet rays is very obvious. In areas with serious air pollution, ultraviolet rays are blocked, which will cause animal rickets. Similarly, in the seaside with less dust content, ultraviolet rays will be very strong.

The reflection of the sea and the beach. The reflection of sea water and beach is so strong that sometimes, even under the condition of shading, the skin will be "sunburned" by the reflected light.

To put it simply, first, ultraviolet rays are stronger in summer, and second, because in water, the water surface will reflect sunlight, which makes the skin receive a larger dose of ultraviolet rays, so it is easier to tan.

In fact, tanning is a protective mechanism of the skin: the blackening of the skin is due to the increase in the number of epidermal melanocytes, which helps to absorb ultraviolet rays and protect the deep skin from damage.
