Sunlight exposure is reportedly associated with reduce breast cancer risk. A new study conducted by the researchers from the University of Buffalo and the University of Puerto Rico found that there was lower risk of breast cancer associated with greater sun explosive among individuals living with high, continuous sun exposure.

Sunbathing can also improve people mood. Sunlight exposure increases the levels of serotonin, a hormone that helps reduce people’s feelings of depression and anxiety and increase feelings of happiness.

Radiotherapy is a treatment using ionizing radiation, commonly X-rays, to kill cancer cells, and skin reaction is one of the most common side effects of radiotherapy.
