The sun provides essential nutrients, such as Vitamin D, and has also been shown to treat seasonal affective disorder. However, for many people, prolonged sun exposure can lead to sunburns and even skin cancer.

Those with high risk factors for skin cancer should be particularly careful of extended periods spent in the sun. A person with light skin color, freckles, blonde or red hair and blue or green eyes has an increased chance of getting skin cancer, though anyone who is frequently sunburned increases their risk exponentially. According to the Center for Disease Control, frequent sunburns early in life (before the age of 20) could also lead to cancer.

In order to potentially prevent skin cancer, people with high risk factors should avoid direct sunlight when its rays are strongest, from 10 a.m. to 4 p.m., and should cover exposed skin if outside during midday. Using sunscreen is essential in avoiding sunburn; a minimum SPF of 15 is necessary to block UV rays, and should be reapplied after extended periods of swimming or sweating.

People often forget their necks and scalps when applying sunscreen, and so it is best to wear a hat to shade those areas while outside. The CDC warns against tanning, either outdoors or at a salon, because tanning beds and sunlamps contain strong UV rays that could easily damage the skin.

During the Southern Nevada “monsoon” season, Las Vegas residents should remember that UV rays can easily penetrate cloudy skies, and so precautions are still necessary to protect skin.

Taking steps to ensure safety during the summer will make it more enjoyable—and in Las Vegas, there is always a cool spot indoors for a local.
