A Strange Rash Had Doctors Stumped. Was It an Insect Bite?
The 73-year-old man looked up at the clear summer sky — the morning was nearly gone. He had finished mowing the main part of his lawn and was trimming the edges near the shrubbery with the weed wacker. He wanted to finish before the sun and heat made the work too hard. Suddenly he felt a sharp sting on the lower part of his shin. He glanced down at his bare leg. Nothing there. He still had the hedges to trim, so he kept working. He quickly finished the needed pruning, then moved on to the inside tasks he had planned.Source: The New York Times Magazine

How much sunlight you really need to get enough vitamin D
The sun is our most common source of vitamin D since it's rarely found in foods. In fact, when exposed to ultraviolet B (UVB) rays, our skin produces vitamin D naturally. Yet, about 35% of adults in America have a vitamin D deficiency. Important: Adults need about 15 micrograms of vitamin D daily to meet nutrient requirements. And that's a problem since vitamin D is important for strengthening and maintaining bones, supporting a healthy immune system, and breaking down glucose in the body, says David J. Leffell, MD, chief of Yale Medicine Dermatologic Surgery and professor of dermatology at Yale School of Medicine. Here's how to make sure you're getting enough of it from the sun.Source: Insider
Psoriasis Causes, Plus 7 Things That Can Cause Symptom Flare-Ups, According to Dermatologists
A psoriasis flare-up can be uncomfortable, both physically and emotionally—and all the more frustrating when it strikes at an inopportune time.

How to differentiate harmless sunspots from skin cancer
Sunspots are flat, dark spots that appear on parts of your skin that you frequently expose to the sun, such as your face, hands, arms, shoulders, and feet. While anyone can develop these spots, they are particularly common in people with light skin over the age of 40, especially those who spend a lot of time in the sun. Genetics also play a role, so having a family history of sunspots can make you more likely to get them. Note: Sunspots are also known as age spots, solar lentigines, and liver spots although they don't have anything to do with liver function. Sunspots are permanent marks that are harmless, so you don't need to remove them for health reasons. However, if you don't like their appearance, there are steps you can take to lighten them. Here are some tips on how to prevent sunspots and reduce their appearance, as well as how to differentiate a sunspot from something more serious like skin cancer.Source: Insider

Genital psoriasis might explain those dry, itchy genitals — but don't let it interfere with your sex life
Psoriasis is a chronic skin condition that causes red, itchy patches or bumps on the skin. It can develop anywhere on the body, including the genitals.

Hell's itch is a rare sunburn reaction that feels like 'fire ants under the skin'
Ultraviolet (UV) rays can cause plenty of skin damage and pain if proper precautions aren't taken. As if a painful sunburn isn't bad enough, in rare occasions, it can escalate. This phenomenon is referred to as "hell's itch". What is hell's itch? Hell's itch is a rare, extremely uncomfortable response to a sunburn, says dermatologist David J. Leffell, MD, section chief of the Dermatologic Surgery and Cutaneous Oncology Programs at Yale Medicine. It will typically crop up two days after a severe sunburn has occurred, and will last for two or more days. "It is described as a maddening, uncontrollable itch of the affected skin. Some have described it as deep sandpaper rubbing on the skin or severe pins and needles," says Leffell. The scientific literature has minimal information on the phenomenon of hell's itch. One of the only mentions of it in medical journals is a firsthand account by a medical student that was published in 2018 in the Journal of Travel Medicine.Source: Insider
