Dermatologist Tips - Why the Summer Sun Feels More Intense [Hot, Hot!] - Dr. Bailey Skin Care [2018] - YouTube Dr. Bailey Skin Care

Have you noticed you burn more in the summer than you do in the winter? There is a scientific reason for this, and it has less to do with your skin and more to do with our planet. However, it’s still very important to understand if you want to maintain youthful-looking skin and avoid sun spots and wrinkles. First, it’s key to understand the two different types of Ultraviolet Light (UV Rays): UVA and UVB. One of the main differences between these two are the length of their waves — a.k.a. wavelength. UVB has shorter waves than UVA and is mostly absorbed by our ozone. In the summer, our skin receives more UVB than the winter. However, UVA is more intense than UVB on Earth’s surface. Typically, UVB only makes up about 5% of UV rays on Earth (UVA makes up the other 95%), especially in the summer, but that 5% is the main reason it feels so strong and leaves us with a burnt-skin appearance. It’s mostly that 5% of the UV rays that burn our skin. Why is there less UVB in the Winter? This is the result of our planet rotating on its axis and the depth of our ozone. In the winter, our planet is tilted away from the sun and the UV rays have to travel a longer distance through the ozone layer to reach us. The ozone layer absorbs UV rays. In the summer, the sun is directly overhead and has a more direct path to our planet’s surface and less ozone to pass through. This is why we burn more in the summer. The example I provide in the video makes sense no matter what hemisphere you are in. If you live in the Southern Hemisphere, it still applies to you in your summer and when the sun is directly over your head. The UVB increase in the summer is important for short- and long-term effects on your skin which can include: sunburns, tanning, wrinkles, and skin cancer. Roughly 80% of a sunburn is the result of too much UVB exposure. This means UVA is still a dangerous ray and not one to be taken lightly.
