Rosacea, a skin condition characterized by redness and swelling, is incredibly common: A recent study found that an estimated 300 million people worldwide suffer from it. Here’s what you need to know about the condition.

1. IT HAS A LONG HISTORY.

According to the National Rosacea Society (NRS), rosacea was first described in the 14th century by a French surgeon named Dr. Guy de Chauliac; he called it goutterose (“pink drop” in French) or couperose and noted that it was characterized by “red lesions in the face, particularly on the nose and cheeks.”

2. SCIENTISTS AREN’T SURE WHAT CAUSES IT ...

But they have some theories. According to the NRS, “most experts believe it is a vascular disorder that seems to be related to flushing.” Scientists also think that because rosacea seems to run in families, it might be genetic. Other things—like mites that live on the skin, an intestinal bug called H pylori (common in those who have rosacea), and a reaction to a bacterium called bacillus oleronius—could also play a role in causing the condition. One 2015 study suggested an increased risk among smokers.

3. … BUT SOME PEOPLE ARE MORE LIKELY TO HAVE IT THAN OTHERS.

Though people of all ages and skin tones can get rosacea, fair skinned people between the ages of 30 and 50 with Celtic and Scandinavian ancestry and a family history of rosacea are more likely to develop the condition. Women are more likely to have rosacea than men, though their symptoms tend to be less severe than men’s. But men are more likely to suffer from a rare rosacea side effect known as rhinophyma, which causes the skin of the nose to thicken and become bulbous. It’s commonly—and mistakenly—associated with heavy drinking, but what exactly causes rhinophyma is unclear. According to the NRS, “The swelling that often follows a flushing reaction may, over time, lead to the growth of excess tissue (fibroplasia) around the nose as plasma proteins accumulate when the damaged lymphatic system fails to clear them. Leakage of a substance called blood coagulation factor XIII is also believed to be a potential cause of excess tissue.” Thankfully, those who have rhinophyma have options available for treatment, including surgery and laser therapy.

4. THERE ARE FOUR SUBTYPES.

According to the American Academy of Dermatology (AAD), rosacea “often begins with a tendency to blush or flush more easily than other people.” All rosacea involves redness of some kind (typically on the nose, cheeks, chin, and forehead), but other symptoms allow the condition to be divided into four subtypes: Erythematotelangiectatic rosacea is characterized by persistent redness and sometimes visible blood vessels; Papulopustular rosacea involves swelling and “acne-like breakouts”; Phymatous rosacea is characterized by thick and bumpy skin; and Ocular rosacea involves red eyes (that sometimes burn and itch, or feel like they have sand in them [PDF]), swollen eyelids, and stye-like growths.

5. IT’S NOT THE SAME AS ACNE.

Though rosacea was once considered a form of acne—"acne rosacea" first appeared in medical literature in 1814—today doctors know it’s a different condition altogether. Though there are similarities (like acne, some forms of rosacea are characterized by small, pus-filled bumps) there are key differences: Acne involves blackheads, typically occurs in the teen years, and can appear all over the body; rosacea is a chronic condition that occurs mainly on the face and the chest and typically shows up later in life.

6. YOU CAN FIND IT IN CLASSIC ART AND LITERATURE.

Both Chaucer and Shakespeare likely made references to rosacea. Domenico Ghirlandaio’s 1490 painting An Old Man and His Grandson seems to depict rhinophyma, and some believe that Rembrandt’s 1659 self-portrait shows that the artist had rosacea and rhinophyma.

7. IT MAY BE TRIGGERED BY CERTAIN FOODS AND ACTIVITIES.

According to the National Institutes of Health (NIH) [PDF], people report that everything from the weather to what you eat can cause rosacea to flare up: Heat, cold, sunlight, and wind, strenuous exercise, spicy food, alcohol consumption, menopause, stress, and use of steroids on the skin are all triggers.

8. THERE ARE A NUMBER OF MYTHS ABOUT ROSACEA.

No, it’s not caused by caffeine and coffee (flare ups, if they occur, are due to the heat of your coffee) or by heavy drinking (though alcohol does exacerbate the condition). Rosacea isn’t caused by poor hygiene, and it’s not contagious.

9. THERE ARE SOME PRETTY FAMOUS PEOPLE WITH ROSACEA.

Sophia Bush, Cynthia Nixon, Kristin Chenoweth, Bill Clinton, and Sam Smith all have rosacea. Diana, Princess of Wales had it, too. W.C. Fields had rosacea and rhinophyma, and Andy Warhol may also have suffered from those conditions.

10. IT CAN’T BE CURED—BUT IT CAN BE TREATED.

The NRS reports that “nearly 90 percent of rosacea patients [surveyed by NRS] said this condition had lowered their self-confidence and self-esteem, and 41 percent reported it had caused them to avoid public contact or cancel social engagements.” Dr. Uwe Gieler, a professor of dermatology at the Justus-Liebig-University in Giessen, Germany, and one of the authors of the report Rosacea: Beyond the Visible, said in a press release that "People with rosacea are often judged on their appearance, which impacts them greatly in daily life. If their rosacea is severe, the symptoms are likely to be more significant also, from itching and burning to a permanently red central facial area. However, even people with less severe rosacea report a significant impact on quality of life."

Which makes it all the more unfortunate that there’s not a cure for the condition. Thankfully, though, there are treatments available.

There are no tests that will diagnose rosacea; that’s up to your doctor, who will examine your medical history and go over your symptoms. Doctors advise that those with rosacea pay attention to what triggers flare-ups, which will help them figure out how to treat the condition. Antibiotics might be prescribed; laser therapy might be used. Anyone with rosacea should always wear sunscreen [PDF] and treat their skin very, very gently—don't scrub or exfoliate it. The AAD recommends moisturizing daily and avoiding products that contain things like urea, alcohol, and glycolic and lactic acids.

10 Facts About High Blood Pressure

People with high blood pressure (hypertension) are at a greater risk for a host of medical issues, including heart failure and stroke. Despite the severe health threats it poses, high blood pressure often goes unnoticed or untreated by some who have it. From high blood pressure symptoms to what levels are considered normal, here are some facts about the condition.

1. High blood pressure symptoms are sometimes unnoticeable.

Blood pressure is a measurement of the force of blood moving through the circulatory system. High blood pressure, a condition in which blood is putting too much force on arteries and organs, is often called the “silent killer.” It contributes to hundreds of thousands of deaths each year, but only half of high blood pressure patients know they have it. In most cases, hypertension signs are difficult to detect, making it hard to diagnose and keep under control. Chest pain, dizziness, shortness of breath, and heart palpitations are some of the most common hypertension signs in people who do show symptoms.

2. Anxiety causes some of the same symptoms as high blood pressure.

When it comes to managing high blood pressure symptoms, mental health is as important as physical health. Anxiety can lead to sudden spikes in blood pressure, and spikes that occur often enough can inflict serious damage on the heart and blood vessels the same way chronic high blood pressures does. Stress and anxiety also make people vulnerable to the top risk factors associated with chronic hypertension, such as smoking, excessive drinking, and overeating.

3. A normal blood pressure range is lower than it used to be.

If you haven’t had your blood pressure measured in a couple years, it’s time for a check-up: In November 2017, the American College of Cardiology and the American Heart Association updated its normal blood pressure guidelines. The two components that make up blood pressure are systolic pressure—the pressure in blood vessels, represented by the top number in test results—and diastolic pressure, the pressure in the heart between beats represented by the bottom number. According to the old guidelines, the threshold for normal blood pressure was 140 systolic pressure and 90 diastolic pressure, or 140/90. The new guidelines lowered that marker to 130/80. Now that the normal blood pressure range has dropped, 14 percent more people could diagnosed with hypertension in the U.S.

4. "White-coat hypertension" is real.

Not every patient who exhibits hypertension signs in the doctor’s office has high blood pressure. “White-coat hypertension” occurs when patients get nervous in a medical setting, leading to a spike in blood pressure that doesn’t necessarily reflect their true health. But this type of hypertension should be taken seriously, even if it is a product of nerves. According to one study, people with white-coat hypertension have a greater chance of developing cardiovascular disease than those with normal blood pressure levels. This may be because people with white-coat hypertension are more prone to anxiety.

5. People with high blood pressure should consume less than one teaspoon of salt per day.

One of the worst things to eat if you have hypertension is food that’s high in salt. Sodium, which makes up 40 percent of table salt (sodium chloride), promotes water retention in the body. More water means more blood volume, which puts added pressure on the heart and blood vessels. Medical experts recommend consuming no more than 2300 milligrams of sodium per day, or just over 1 teaspoon of salt. If you have high blood pressure, the American Heart Association recommends an ideal limit at 1500 milligrams of sodium a day—equal to three-quarters of a teaspoon of salt.

6. Almost half of U.S. adults have high blood pressure ...

According to the American Heart Association, more than 100 million people in the U.S. have high blood pressure—that’s nearly half of American adults. The condition is so common that even if you don’t have it now, chances are you will develop it at some point in your life. The lifetime risk in the U.S. for hypertension in 90 percent.

7. ... and black Americans are most affected.

High blood pressure affects certain groups disproportionately. Black Americans are more likely to have high blood pressure than any other group in the country, and when they develop it, it’s usually more severe. Hypertension also affects black Americans earlier in life: Three in four black people in the U.S. will develop the condition by age 55. Health experts believe that the prevalence of high blood pressure is associated with the higher rates of obesity and diabetes among the black population.

8. A female hormone may protect against high blood pressure.

High blood pressure rates are pretty similar among men and women before middle age. But once women hit menopause, their chances of developing hypertension increase: 75 percent of postmenopausal in the U.S. have high blood pressure. This may have to do something with decreased levels of estrogen—a hormone that’s been shown to boost premenopausal women’s vascular health.

9. High blood pressure can be life-threatening ...

High blood pressure doesn’t kill people directly, but it can lead to some deadly complications. Hypertension adds potentially fatal stress to vital organs like the heart, kidneys, and brain. When you have high blood pressure, your risk of heart attack, stroke, chronic heart failure, kidney disease, and even blindness all significantly go up.

10. ... but improved with medications and healthy living.

The best way to reduce your blood pressure is to change your lifestyle. Smoking, drinking too much alcohol, and eating too much salty food all increase your risk of developing hypertension, and doctors recommend avoiding these risk factors to keep blood pressure levels under control. Regular exercise and certain medications, like diuretics (to get rid of excess water in the body) and ACE inhibitors (which block an enzyme that tightens blood vessels), can also lower blood pressure.

A Simple Hack for Recycling Your Contact Lens Blister Packs

As convenient as monthly and daily-use contact lenses can be for those who aren't blessed with 20/20 vision, they can also be harmful to the environment and contribute to microplastic pollution when they’re flushed down the drain.

The good news is that the blister packs your contact lenses come in can be recycled in a way that requires very little time and effort. If you're a contact lens wearer and want to do your part to reduce plastic waste, there’s a simple solution: Just place the empty blister packs inside a plastic bottle and drop it into the plastic recycling bin once it’s full. (Just make sure you're discarding the foil covering the blister pack first.)

Of course, it’s always better to use as few plastic bottles as possible, so only do this if you were already using those bottles anyway. If your household is fairly anti-plastic, there’s another option. Contact lens manufacturer Bausch + Lomb offers its own recycling program, called One by One. The company collaborated with TerraCycle to reduce waste by recycling all parts of the product, including the used blister pack, top foil, and contact lenses themselves. The company accepts all brands of contact lens products and estimates that it has recycled more than 25,000 pounds of packaging to date.

“Once received, the contact lenses and blister packs are separated and cleaned,” Bausch + Lomb explains on its website. “The metal layers of the blister packs are recycled separately, while the contact lenses and plastic blister pack components are melted into plastic that can be remolded to make recycled products.”

The reason why so many plastic blister packs end up in landfills is because the pieces are too small to be sorted properly at recycling plants. It’s the same problem that affects plastic bottle caps, which is why it’s recommended to leave the caps on, as long as your recycling program allows it.

Optometry offices across the country are participating in Bausch + Lomb's recycling program, and you can visit the company’s website to find out if there are any drop-off points near you. If it's more convenient, you can also place the items in a cardboard box and mail them in, using a free shipping label that’s available online.
