Show 1438: Bites, Burns, and Blisters? Solving Summer Skin Problems!

This week, we asked dermatologist Dr. Chris Adigun into our studio to answer your questions about summer skin problems.

The Link Between Sun Exposure and Skin Cancer:

Intense summer sunshine can cause sunburn and skin damage. The most worrisome consequences are skin cancers that may show up on cheeks, ears, noses, lips or other unexpected places. How can you recognize a potential skin cancer? What will the dermatologist do about it? Even more important, can you reduce your risk for basal or squamous cell carcinoma? (Those are technical terms to describe skin cancers that are not melanoma.)

What are the best ways to avoid harming your skin while you are enjoying the great outdoors, whether you are at the beach or on the hiking trail? Are there criteria you can use to choose the best sunscreen without spending a fortune? How often do you need to apply it? Can you get enough vitamin D compounds if you wear a high SPF sunscreen?

Are there skin conditions that might actually benefit from a bit of sun and salt water?

Lowering Your Chance of Melanoma:

The relationship between sun exposure and melanoma is less clear than that between sun and basal or squamous cell cancers. Find out what might make a spot suspicious. Where should you be checking your skin? What can a dermatologist do to help?

Heat and Humidity Challenges:

In addition to sun, heat and humidity can challenge our skin. Fungal infections may proliferate under those conditions, resulting in athlete’s foot, jock itch or under-breast rash. Can we make our sweaty skin less hospitable to fungi?

Have you been troubled with heat rash? We’ll find out what it is and what to do to get rid of it.

Other Summer Skin Problems:

Long summer hikes can result in more trouble than sunburn or sore muscles. Unless you are very careful with your shoes, sweaty feet can develop blisters. Are there good preventive strategies? If you get a blister anyway, what can you do to ease the pain–and keep it from getting worse?

Bug bites may also be the bane of your existence. Chiggers hang out in grass or brush waiting to take a bite of a tasty mammal walking by. Can you avoid or discourage them? And if you do get chigger bites, how can you manage the dreadful itch?

We also want to avoid bites from ticks and mosquitoes. They may have different niches and behaviors, so avoiding them may require different tactics. What works best? How can you choose a good insect repellent for outdoor activities, and will it interact with your sunscreen?

Poison Ivy and Its Cousins:

Poison ivy, poison oak and poison sumac all contain the resin urushiol, which can be extremely irritating to sensitive skin. Do you know how to identify these plants so you can avoid them? If you find yourself in the middle of a poison ivy thicket, can you take quick action and reduce the chance of a rash? If you end up with a rash–it happens–we’ll find out how you can ease the suffering.
