The Ocean is a deep and scary world that is completely removed from most of our lives. In this video I explore just how deep the ocean actually is while discussing some of the strange life down there… and other just plain weird and odd things about the ocean.
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!
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.
Almost every dog does the head tilt, but what exactly does it mean? Confusion? Curiosity? Or is it just them being cute and hoping for a tasty treat? Well, here’s what may be going on.
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.
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.
If you are a heavy coffee drinker and one day decide to cut back and stop drinking coffee entirely, chances are you’ll experience some pretty bad headaches. In this video, the folks from SciShow tell you exactly why this is happening.
I normally drink about ten cups of coffee per day but today I decided to cut back and haven’t had any caffeine but now my head hurts and I don’t know why do YOU know why!?

Have you ever wondered how insects can survive through the winter? Check out this episode of the Scishow to find out how!
Birds fly south, humans bundle up, but what do insects do to survive the winter? From creating antifreeze-like alcohols to burrowing in the ground, bugs have a few solutions to carry on.
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.
The science behind dark circles under your eyes, and all the things that might cause them
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.
