Most of us have dealt with acne during puberty, or maybe even after that. You probably wanted to pop or pick them in order to remove them, but don’t do that! Learn more about acne and learn how to get rid of it more appropriately!

Enjoy!

Zits are annoying and they tend to pop up at the absolute worst time. Before you try to pop them, though, check out this video for some better ways to get rid of acne.

This video from SciShow explains how zits are formed when bacteria collect in the pores of your skin and create tiny infections. While popping a zit is an attractive short term solution, this can spread the infection to the surrounding area of your skin. That’s likely to make the overall problem worse.

Instead, the video suggests that acne treatments that prevent bacterial growth and lower inflammation. You can use over the counter topical treatments on your skin to help reduce acne overall. In severe cases of acne, you may want to look into prescription treatments.

7 Things You Should Know About Bed Bugs

One in five Americans either has had bed bugs, or knows someone who has. And the problem isn’t going away. It’s actually getting a lot worse.

They’re tiny, resilient, and they want to suck your blood. Bed bugs are a serious issue that isn’t going away any time soon. Here’s what you need to know about the microscopic monsters.

As this video from the SciShow YouTube channel explains, bed bugs are one of the fastest growing pest problems in the developed world—and it’s getting worse. If you’re unfamiliar with bed bugs, or Cimex lectularius, they’re tiny, blood-feeding insects that have acquired a taste for us humans over thousands of years. In the video, you’ll learn that bed bugs can live just about anywhere in your home, stuffing bedding and mattresses in plastic bags to starve out bed bugs doesn’t work, and the most efficient way to kill a bunch of bed bugs is heat. Adults and eggs will die within 10 minutes if exposed to temperatures of 115 degrees Fahrenheit (but don’t go lighting your bed on fire.) Fortunately, bed bugs don’t seem to pass on disease like most other blood-feeding insects, so you can take some solace in that.

There are some things you can do to fight off bed bugs, like freezing blankets and linens for several weeks, or calling an exterminator. But the best thing you can do is try to prevent them. Seal up cracks and crevices around your home so they don’t have anywhere to hide, check hotel rooms for them so you don’t any home, and set out traps.

All people are either A, B, AB or 0 blood type from birth.

The 8 Facts About The Blood Types

Experts say that every type has its own traits and here is the list:

1. Blood type and offsprings

85% of people are Rh + and if the woman is Rh- and man is Rh+ for conceiving, there is risk of health issues in the child.

2. Blood type and diseases

Depending on the health, every type is more or less prone to issues so check this out.

3. Blood type and diet

Know your type and see which diet suits you best and which has to be avoided. Type A need more veggies, 0 need more fish and meat, AB seafood and lean meat and B need red meat.

4. Blood antigens

These are in the GI tract, blood, nostrils and lungs, but also colon and mouth.

5. Blood type and stress

Those with type 0 need more relaxing than the rest.

6. Blood type and weight

The type also says a lot for the weight. Type 0 can have more belly fat, and type A have almost no issues.

7. Blood type and pregnancy

Women with AB conceive easier than the rest and have less making of follicle-hormones.

8. Blood type and urgencies

If you need blood transfusing, know that 0 type Rh- can be universal donors and AB are universal recipients.

Do Hats Cause Balding?

Is it true that if you wear a hat often enough it will cause you to bald?

There are a few things that are known to induce hair loss, but wearing hats isn’t one of them—even if you wear one every day. Here’s the truth about that old wives’ tale.

In this video from the Mental Floss YouTube channel, Craig Benzine explains the leading causes of hair loss: poor nutrition, drugs, infection, pregnancy, trauma, and the biggest factor of them all, genetics. There is, however, a condition known as traction alopecia that causes hairlines to recede due to, well, consistent traction or rubbing. The skin gets damaged and scars over the hair follicles so nothing can grow there anymore. Wearing tight ponytails, hair barrettes, or helmets on a regular basis can put you at risk. But only wearing a hat isn’t enough to cause that unless it was extremely tight on your head.

That said, wearing hats can speed up the balding process if you’re already losing your hair due to genetics or other causes. Taking the hat off can pull out hairs, and if it’s too tight, adjusting it can also yank some out. So wear your hats just a little bit loose and you’ll be fine.

Why You Get Dark Circles Under Your Eyes

The science behind dark circles under your eyes, and all the things that might cause them

Enjoy!

Dark circles under or around your eyes make you look tired, but there plenty of other reasons you might get them. Here’s the science behind dark eye circles, and how you can try to avoid them.

As this video from the SciShow YouTube channel explains, the main reason why your skin might look darker in the area around your eyes is because the skin is thinner in that area and there’s less fat to hide the tiny blood vessels there. Additionally, the natural pigmentation of your skin, or the amount of melanin in the skin in that area, is a factor as well. So genetics play a huge part, and there may not be a way for you to get rid of them entirely. That said, there are some things that can make them much worse.

If you don’t get enough sleep or you’re always stressed out, your body will produce more cortisol in an effort to keep you alert. Over time, cortisol can constrict blood vessels or, in this case, dilate them and make the ones under your eyes bigger. Allergies can be a major cause as well. Allergic reactions cause your body to release histamines, which also dilate blood vessels. Also, sunlight can damage the skin cells around your eyes and kill them off if you don’t protect your face. Less skin cells means thinner skin, which means darker circles. And lastly, as you get older, you have less fat underneath the skin and it gets thinner.

The best things you can do to fight off those dark circles is to wear sunscreen, get plenty of sleep, take your allergy medication, and avoid stress as much as possible. Clearing your sinuses can help too if you have any nasal congestion.

If you try and read the “words” in the title above from left to right, you’ll realize right away that you can’t — the first few characters aren’t even letters. Try it from right to left and it’s not much better. But read it upside down, and you’re likely in business. It says “upside down but looking normal,” and it describes the experiences of a man named George M. Stratton.

Maybe.

Stratton was born in 1865 in Oakland, California. By his early thirties, he was a professor of philosophy at the University of California, Berkeley, but he took interest in psychology. He switched disciplines, became the school’s first chair of its psychology department, and founded the school’s first experimental psychology lab (and one of the first in the nation at that). And for one of his experiments, he found a very willing test subject — himself.

It started with something that looked like a crude version of this:

inverting glasses

Those are a modern version of something called “inverting glasses” which, as the name suggests, makes the world appear upside down. About 120 years ago, Stratton fashioned a pair for himself, wore them for about 21 and a half hours straight, and recorded his findings. What he learned (pdf) was that trying to navigate the world while looking at it flipped on its head isn’t very fun — you feel nauseous and disoriented throughout. The good news was that when he took the glasses off, he felt much better nearly immediately. The bad news (beyond the nausea etc., that is), was that his brain couldn’t compensate for the changes in visual inputs.Undaunted, Stratton tried the experiment again — but this time, wore the inverting glasses (or went blindfolded, to sleep) for eight days straight. And this time, Stratton reported, his brain flipped the world back into position. Wikipedia summarizes:

By day four, the images seen through the instrument were still upside down. However, on day five, images appeared upright until he concentrated on them; then they became inverted again. By having to concentrate on his vision to turn it upside down again, especially when he knew images were hitting his retinas in the opposite orientation as normal, Stratton deduced his brain had reprocessed his vision and adapted to the changes in vision.

Amazing — but not necessarily completely true. Stratton’s experiment didn’t meet more modern standards for such things; for example, his test group was very small (one person) and included someone (himself) with a vested interest in a certain outcome. The small sample size plus the inherent risk of bias gave future generations reason enough to try to replicate Stratton’s findings, and they haven’t been able to, at least not entirely. As io9 reported, in one relatively recent study (1999), test subjects donned inverting glasses for a six to ten day time period. The world didn’t turn upside down for them — so that part of Stratton’s findings haven’t been replicated.

However, our brains do compensate to a large degree. The subjects “reported feeling as though they had been turned upside down in the regular world. Essentially, even though they knew it wasn’t true, they felt like they were walking on the ceiling or the sky.” So while it’s unclear what Stratton saw and experienced, it’s likely that he was able to navigate the upside down world after a while. Just like the title of this article, if you look at something upside down for long enough, it begins to make sense.
