SPF: It’s Not Just for Summer

If you equate sunscreen with summer and tuck it away once the weather turns cool, you may need to rethink your strategy.

While it’s true that UVB rays are strongest in the summer, they can cause sunburn and lead to damage any season of the year. Winter is of particular concern in our region as snow reflects up to 80% of UV rays, meaning you’re getting nearly a double dose of damaging rays on sunny days. Without proper protection, all that exposure can increase your risk of developing skin cancer and joining the ranks of the estimated 9,500 Americans diagnosed with skin cancer every day. Tragically, one person dies of melanoma—the deadliest type of skin cancer— every hour, every day. 

To reduce your risk in winter and beyond, keep these facts in tip in mind:

Elevation matters

Snowsport lovers have a higher chance of skin damage during the winter months as UV levels rise 4-5% with every 1000 feet of elevation above sea level gained.

Every day is a sunscreen day

Regardless of the temperature or cloud cover, applying a broad-spectrum sunscreen with an SPF of 30 or higher to exposed skin should be a part of your daily routine. For best results, apply sunscreen at least 30 minutes before heading outdoors.

The lips don’t lie

With very little melanin, the pigment that helps protect against sunburn, the lips are one of the most vulnerable parts of the body and the most prone to painful sunburn. To protect your lips, apply a lip balm with an SPF of 30 or higher when venturing out in any season. Be sure to reapply frequently, especially if eating, drinking, or swimming.

Measure once, apply twice (at least)

Sunscreen only works if you apply the correct amount and repeat application for extended stays outside. For your face, ears and neck, use approximately ⅓ teaspoon to ½ teaspoon of sunscreen. For the full body, bump the amount up to 1 to 2 ounces (enough to fill a shot glass). Be sure to re-apply every two hours and after swimming or heavy sweating.

You missed a spot

Parts of the body commonly missed when applying sunscreen include:

  • Tops of the ears

  • Back of the hands

  • Tops of the feet

  • Lips

  • Sides of the neck

  • Behind the knees

  • Eyelids

  • Scalp

  • Upper chest.

Moving Forward Safely

One of the most frustrating and anxiety-producing traits of our COVID –19 pandemic is how much uncertainty is involved in all aspects of this disease. Symptoms caused by the Coronavirus, age groups affected, the usefulness of medications, anticipated death rate, and the timeline for development of a vaccine are examples of information that sometimes change on a weekly basis.

Vermonters have done a great job of limiting the spread of the virus and protecting our most vulnerable neighbors by following the Governor's "Stay Home, Stay Safe" order over the past few months. Now, we've all been directed to wear masks in public. Both Bennington and Wilmington's Select Boards have passed local mandates requiring masks in public places. Thanks to these efforts—along with distancing, handwashing, and other factors—Vermont is among the states with the fewest number of infections. Continuing each of these important infection-prevention strategies is crucial to returning to a more normal way of life.

As we open up and begin to re-connect, we fully expect to see a rise in COVID –19 cases in Vermont. Thankfully, we have had time to prepare for this increase. We also have adequate PPE, and increased testing will help us gather crucial information for stemming the spread with less disruption to our normal lives.

More than ever, I find it helpful to focus on what we have learned and how it can help us move forward safely. Here is some of what we have learned so far: Most large hospitals, often treating over 1000 COVID patients daily, effectively protected their workers by obsessively following the rules of screening, hygiene, distancing, and masking. Each of these components is designed to work together; Each alone has its inherent limits.

  • Absent quick testing at the workplace, the best screening is asking employees if they have COVID-like symptoms (fever, chills, new cough, shortness of breath, sore throat, loss of taste or smell) and to stay home if they do.
  • Washing our hands (or using sanitizer) after touching well-handled items or visiting populated areas. Washing your hands 10 times daily is not too often.
  • Though an uncovered sneeze or cough can travel farther, 6 feet distancing continues to be the sweet spot for safety.
  • Masks (double layer cotton and surgical) are effective to prevent spreading of large and some small droplets containing virus. They also seem to give some minimal protection to those wearing a mask. Since possibly 40 percent of transmission happens when we do not have symptoms, we wear our masks to protect others and to suppress overall infection rate. They also help many people (not all) to avoid touching their face. The downside is a warm chin; the upside is you may be protecting someone from a significant illness. Masks are not a symbol of government intrusion. Masks are simply a tool to protect others and show empathy.

It is difficult to predict how many COVID-19 infections will occur in our communities in the coming months. What I am certain of is that our choices, on where we go and what we do, often affect the safety of those around us. As we learn to live with this virus in our community, following the recommendation above will help us all.
