Summer will be here soon, and after being stuck inside all winter, it will be welcomed with open arms.

But as we plan trips to beaches and lakes around the country, a lot of us (including myself) will look at our pale arms and legs and think of ways to get that bronze glow to go along with the summer sun.

Millions of people will soon be soaking up the sun’s rays or purchasing a tanning membership in an effort to achieve a sun-kissed look, but take heed: there is one big reason to rethink lying in the sun or under the lamps of a tanning bed.

There are misconceptions that one way of tanning is less damaging than the other—some circles claim natural sunlight is good for your skin, while others believe the artificial lights of the tanning beds are actually better than sunlight.

In reality, both are dangerous, and the danger lies in the increased risk of developing skin cancer.

Snow-lovers rejoice—winter is coming!

And no, this isn’t an allusion to Game of Thrones. With the end of Daylight Savings, the days are becoming darker earlier, which for some can mean the onset of the winter blues. The medical term for this is Seasonal Affective Disorder (SAD), a condition caused by a mélange of changes in our biological clocks, serotonin levels, and melatonin production, all of which affect our mood.

While many of us are familiar with SAD, there are, in fact, people that get SAD in reverse. For a small group of people, the dark days of winter don’t elicit depression, but renewed vigor and improved mood.
