If you’ve ever had to deal with dry winter skin, you may think you know what eczema feels like. But anyone living with the chronic condition will tell you it’s much more than that. Rashes can rear their heads at any time of year, and eczema causes include irritants as mundane as food, clothes, and the weather. Symptoms range from mildly annoying to distracting enough to keep people from getting sleep and focusing on their work. Here are some more facts about eczema causes, symptoms, and treatments.

1. Eczema isn't just one condition.

Rather than describing one specific skin condition, eczema is used as a catch-all term for a group of related conditions. When people mention eczema, they’re often referring to atopic dermatitis: This is a chronic inflammatory condition characterized by dry, itchy red patches that flare up across the body when the immune system overreacts to a trigger. There’s also contact dermatitis, which is when rashes are triggered by irritants coming in contact with the skin; nummular eczema, when rashes are coin-shaped; and stasis dermatitis, when fluid “weeps” out of weakened blood vessels in the skin. Eczema shouldn't be confused with psoriasis: While both are conditions that lead to dry, itchy skin, the latter is an autoimmune condition while the former is primarily caused by allergic reactions.

2. Eczema is sometimes limited to the hands.

Eczema doesn’t have to affect the entire body. Hand eczema comes with many of the same symptoms of regular dermatitis—including chapped skin, painful cracks, red patches, and itchy blisters—but is limited to the hands and forearms. Many people without eczema deal with dry hands, especially during the colder months, so it can be difficult to know when these symptoms are signs of a medical condition. If your itchy, irritated hands can’t be treated with moisturizer alone, ask a dermatologist if you may have hand eczema.

3. It's often genetic.

Your genetic background is a strong predictor of eczema. If both of your parents have it, there’s an 80 percent chance that you will develop it as well, according to the Eczema Association Australasia. A family history of asthma and hay fever is also linked to eczema.

4. Eczema can be debilitating.

A list of symptoms doesn’t begin to capture what the experience of living with eczema is like. The itching and discomfort that comes with it can be so intense that it keeps people up at night, leaving them exhausted and unable to function during the day. Symptoms may be so acute that they’re all the person thinks about, which can hinder their relationships and work life. Others may feel discouraged to go out in public because they’re self-conscious of how their skin looks.

5. It's not contagious.

No matter how much contact you have with someone with eczema, there’s no chance of you catching their skin condition. Despite this, many people will see someone scratching their eczema rashes and assume what they have is just as contagious as poison ivy or chicken pox. And because eczema often runs in families, it sometimes carries the illusion of “spreading” between people who live together.

6. Eczema can be triggered by your environment ...

There are a number of environmental factors that can trigger eczema symptoms. Changes in climate—either to cold, dry conditions or hot, humid ones—may be enough to provoke a flare-up. For many people, chemical irritants are the sources of their rashes. Cigarette smoke, perfumes, household cleaners, shampoos, and fabrics like wool and polyester have all been linked to eczema reactions. That doesn't mean that everyone with eczema needs to avoid these things: The condition affects everyone differently, and an irritant that causes one person’s flare-ups may have zero effect on someone else.

7. ... and stress level.

Even if someone with eczema takes great pains to avoid their environmental triggers, a hard day may be all it takes to make their skin break out. Many people with eczema report exacerbated symptoms when they're feeling stressed. According to the National Eczema Association, eczema sufferers are more likely to be diagnosed with anxiety and depression, creating a vicious cycle for patients who count stress as a trigger.

8. It's connected to allergies.

Eczema is often accompanied by an allergic condition, whether it’s asthma, hay fever, or allergies to food. Up to 80 percent of children with atopic dermatitis go on to develop asthma or hay fever. It’s unclear what the exact relationship between allergies and eczema is, but some medical experts believe that the weakened skin barrier associated with eczema makes it easier for allergens to enter the body, which can in turn impact the immune system over time. Allergens—like pollen, dust, pet dander, and mold— are also triggers for some people with eczema.

9. Scratching makes it worse.

When an eczema flare-up starts to itch, it can be impossible to think about anything else. But scratching a rash is the last thing people with this condition should do. Instead of relieving discomfort, scratching a dry patch of skin can irritate it even further. Sometimes eczema sufferers scratch their skin so much that it starts to bleed, opening the door for potential infections.

10. Eczema is more common in kids.

Eczema affects roughly 11 percent of U.S. children [PDF] and 7 percent of adults [PDF]. Most kids with eczema develop it within the first five years of life, with 65 percent percent of child eczema patients first showing symptoms as infants. Living with eczema can be taxing for both kids and parents—especially when kids can’t stop themselves from scratching their rashes—but fortunately, half of kids with the condition grow out of it by the time they reach their teen years.

11. It can't be cured—but it can be treated.

There’s no cure for eczema, but there are some treatments that can help keep aggressive symptoms under control. Above all, eczema patients should keep their skin clean and moisturized to prevent flare-ups. Doctors recommend taking regular showers with warm water (but not hot water, as that can dry skin even more), and applying moisturizer immediately after bathing. If regular moisturizer isn't enough to soothe skin, doctors may prescribe a topical ointment with steroids to reduce inflammation, and if that still isn't effective, systemic medications that fight inflammation throughout the whole body may help. Ultraviolet B therapy is another treatment option. A few times a week, patients stand in a UVB light box that mimics natural sunlight. This encourages vitamin D production and curbs skin's inflammatory response while calming itchiness at the same time.

11 Facts About Anemia

Anemia is so pervasive that the word anemic has become synonymous with a lack of vitality, substance, or flavor. But anemia symptoms go beyond the common signs of pallor and fatigue. The disorder is characterized by a lack of red blood cells or hemoglobin in the body that arises from a variety of underlying conditions—some that are serious and others that are barely noticeable. Anemia causes can even include pregnancy, poor diet, and cancer in rare cases. Here are some more facts worth knowing about anemia symptoms and treatments.

1. The most common type is iron deficiency anemia.

The body needs iron to produce hemoglobin—the protein that allows red blood cells to transport oxygen throughout the body—and when it doesn’t get enough of it, iron deficiency anemia can develop. Vitamin deficiency anemia works in a similar way. The vitamins B12 and folate are also essential to producing healthy red blood cells, and deficiencies in either vitamin can contribute to anemia. Patients may be lacking iron, B12, or folate because they’re not getting enough of the vitamins or mineral from their diet, or because their body has trouble absorbing them, either due to gastrointestinal surgery, a genetic disorder, or some other issue. In contrast, sickle cell anemia is an inherited condition in which malformed hemoglobin can't carry enough oxygen, causing blood cells to take on a crescent shape and impede blood flow.

2. Even mild anemia symptoms should be taken seriously.

There are roughly 400 different anemia causes. Some are relatively benign, like not including enough leafy greens in your diet, while others are more serious, like blood cancers or aplastic anemia, a condition that develops when bone marrow stops producing red blood cells at a healthy rate. Mild anemia may be one of the first signs of a serious condition that impedes your blood cell production, so even if the symptoms of the anemia itself are manageable, it shouldn’t be brushed off as nothing.

3. Anemia is Greek for lack of blood.

Put simply, someone with anemia doesn’t have a healthy amount of red blood cells or hemoglobin in their bloodstream. The word is a Latinized version of the Greek word anaimia, which means lack of blood (an meaning "without" and haima meaning "blood").

4. The fatigue comes from a lack of oxygen.

Even with a healthy respiratory system, the tissues of people with anemia may not get enough oxygen—a phenomenon known as hypoxia. This can lead to symptoms like headaches, dizziness, shortness of breath, and fatigue. While these symptoms can be debilitating in patients with severe anemia, they may be mild or even nonexistent in people with less severe cases. The signs are also hard to measure and can overlap with those of several chronic conditions, which means mild anemia often goes undiagnosed.

5. Anemia compels some people to chew ice.

Constantly craving an ice cube to chew on may be a sign your blood is at anemic levels. Pica is the medical term for the compulsion to chew substances devoid of nutritional value, like ice, dirt, and paper, and it's one of the more distinctive symptoms of iron deficiency anemia. Doctors still aren't entirely sure why the craving afflicts so many anemic patients. One explanation is that ice calms inflammation in the mouth that sometimes comes with iron deficiencies, while additional research suggests that chewing on ice is one way for fatigued people to stay alert.

6. It’s diagnosed with a simple blood test.

Though the symptoms can be tricky to identify, testing for anemia is simple once a doctor suspects a patient has it. After taking a sample, doctors calculate the complete blood count, or CBC, which measures the percentage of red blood cells (a measurement called the hematocrit) and hemoglobin in a patient’s blood. By looking at red blood cell and hemoglobin percentages specifically, they can determine if the patient’s blood is healthy or anemic. The typical adult man has blood with 40 to 52 percent red blood cells (the rest is plasma), and for the typical adult woman, it’s 35 to 47 percent, according to the Mayo Clinic.

7. Anemia is more common in developing nations.

Approximately 25 percent of the world population—almost 2 billion people—is affected by anemia. In about half of these cases, iron deficiency is the root cause. Anemia is more common in developing parts of the world where malnutrition is also rampant, while in the U.S., just under 6 percent of the population is anemic. In the U.S., the prevalence of anemia varies by group: Women, elderly people, African Americans, and Latino Americans are all more likely to have it, with black women between ages 80 and 85 developing the condition at rates 6.4 times higher than the national average, according to a 2016 study. The majority of anemia cases around the world are moderate or mild, and at those levels the lack of healthy blood cells itself doesn’t pose significant health risks (though an underlying disease that's causing it might).

8. Anemia also has a surprising benefit.

Having a low amount of iron in your body has an unexpected effect: It makes it harder for infections to develop. Most bacteria depends on iron to gain strength and spread throughout a host, and in the bodies of people with iron deficiency anemia, bacteria has a greater chance of dying before it multiplies into a dangerous infection. Studies have shown that people with low iron counts have a smaller risk of contracting malaria, tuberculosis, and certain respiratory conditions. Iron deficiency anemia can also boost survival rates in patients with HIV and lower the risk of cancer (like bacteria, cancer cells need iron to grow). Denying pathogens iron is such an effective way of killing them that our bodies naturally slow iron production when they detect an infection.

9. Pregnant people are more likely to have anemia ...

People who are pregnant have a much higher risk of becoming anemic. According to the World Health Organization, anemia affects over 40 percent of pregnant women worldwide. The bodies of pregnant women naturally produce about 20 to 30 percent more blood to supply oxygen to the baby, but it isn’t always enough for the mother to maintain healthy red blood cell and hemoglobin levels. Anemia is especially common during the second and third trimesters when the baby needs the most blood. Pregnant patients with anemia are usually prescribed iron supplements to prevent birth defects and complications during delivery.

10. … and so are vegetarians.

Many people get their iron by eating meat like beef, chicken, pork, and shellfish. Without meat in their diet, people have a greater chance of developing iron deficiency anemia: A small Indian study published in the Journal of Nutrition & Food Science found that approximately 60 percent of vegetarian women were anemic. But it is possible to consume healthy amounts of iron while adhering to a meat-free diet. In addition to dietary supplements, legumes, dried fruits, and leafy greens are great sources of the mineral.

11. Anemia treatments range from vitamins to blood transfusions.

Treatments for anemia vary depending on the cause of the condition. For iron deficiency anemia, the most common variety, doctors usually prescribe iron supplements as well as a diet rich in the foods mentioned above. Daily folic acid tablets and B12 shots—starting once every other day and transitioning to once a month—may also be prescribed to patients deficient in either vitamin. In cases when red blood cell and hemoglobin counts dip into dangerous territory, more drastic treatments like blood transfusions and bone marrow transplants may be necessary.

Hawaii Has Been Named the Healthiest State in America

Hawaii may be thousands of miles removed from the continental U.S., but the state's residents don't seem worse off for it. As Thrillist reports, America's 50th state also happens to be the healthiest one in the nation.

This finding comes from the United Health Foundation, which releases the "America's Health Rankings Annual Report" each year. Factors that affect both physical and mental health, as well as social well-being, are taken into account.

"For nearly three decades, America's Health Rankings Annual Report has analyzed a comprehensive set of behaviors, public and health policies, community and environmental conditions, and clinical care data to provide a holistic view of the health of the people in the nation," the foundation writes on its website.

Hawaii has been named the healthiest state in the U.S. nine times since 1990, when the first report was released. So what exactly are our island-dwelling counterparts doing right? For one thing, the state has low obesity and smoking rates compared to the national average. Residents enjoy low levels of air pollution, very little mental distress among adults, and a high number of available primary care physicians.

Following Hawaii, the healthiest states in the nation are Massachusetts, Connecticut, Vermont, and Utah. The report also highlights the unhealthiest states—or, as the foundation delicately puts it, those that have "the greatest opportunity for improvement." Louisiana fared worst overall for health, largely because of its high rates of smoking, obesity, and children who live in poverty (28 percent). Mississippi comes in 49th place, followed by Alabama, Oklahoma, and Arkansas.

Maine saw the most improvement overall, having jumped seven places to number 16. It primarily improved in the areas of smoking and child poverty. Dropping four places, Oklahoma was the state that saw the biggest decline. Its obesity and physical inactivity rates both went up.
