What risks do infared and ultraviolet pose to humans?

Eye and skin problems.

Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, Infrared radiation (IR), sometimes associated to simply as infrared, is a range of the electromagnetic radiation spectrum where wavelengths differ from about 700 nanometers (nm) to 1 millimeter (mm). These rays extend a person's risk of cataracts and several other eye problems, too. They can also crush the skin's immune system. Darker-skinned people are usually less likely to get skin cancer than light-skinned people, but they can still get cataracts and immune destruction.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
