Make the most of your trip by beating jet lag once and for all.
If you’ve ever travelled more than a few timezones in a few hours, you’ll know that jet lag is terrible.
Waking up in the middle of the night and feeling sleepy and hungry at the wrong times can be all sorts of annoying when all you want to do is explore a new city, or have to be on top form during a work trip.
It happens because your body’s internal clock gets all out of sync.
Every cell in your body has its own circadian clock, and they’re all regulated by a central one called the suprachiasmatic nucleus in the hypothalamus region of your brain. When you skip time zones, it sends these little clocks out of whack.
The good news is external signals help regulate your internal clock, and you can use that to your advantage.
Your hypothalamus judges what time it is by the signals your body sends it, which is mostly based on light, but also when you eat.
Here are some things you can do to help your body adjust and get over jet lag as quickly as possible.
1. Start to shift your body clock before you go anywhere.
Professor Richard Wiseman, author of Night School (Macmillan, 2014), recommends making use of the days before you travel.
There’s some evidence that starting to get up earlier in the few days before traveling east can alleviate some of the horrible fuzziness jet lag brings. A study of 28 people in the Journal of Biological Rhythms found that bringing sleep forward an hour a day for three days and exposing participants to bright light in the morning meant they could advance their sleep pattern without losing out on alertness.
If you’re going west instead of east, you need to delay your sleep pattern, to try sleeping in an hour later per day for the three days before you travel.
2. Adjust your watch as soon as you get on the plane.

And try to do whatever you would at that time. “If it is time to sleep, get your head down. If it is dinner time, eat something,” writes Wiseman.
3. If you need to sleep on the plane, avoid sitting on the sunny side.
It’s going to be hard to convince yourself to sleep if you have bright daylight streaming in through the window next to you. You can use the website Sun Flight to check where the sun will be during your flight to book the best seat.
4. Know whether to seek out or avoid light when you get to your destination.
As a general rule, if you’ve travelled east you’ll need to avoid morning light but make the most of it in the afternoon, says Wiseman. If you’ve travelled west, try to expose yourself to light throughout the day.
If you want to get really detailed, the University of Michigan has created an app called Entrain that can take your normal sleep schedule and travel schedule and tell you exactly when you seek out bright light and when to avoid it.
5. Use sunglasses to control your light exposure.
In a New York Times article, Steven Lockley from NASA’s fatigue management team, recommends wearing sunglasses during a flight if you need to sleep, and at the airport once you arrive if you need to.
For example, on an overnight flight from New York to London, Lockley says you should wear sunglasses for the entire flight and until 11am local time, to help yourself adjust. Don’t seek out bright light right away, because your body thinks it’s the middle of the night and you’ll just exhaust yourself.
6. If you really need to nap when you get there, make sure you time it right.
Between 1 to 2pm in your new timezone is the best time for this, Wiseman told BuzzFeed.
7. Melatonin supplements could help you control your sleeping patterns.

Melatonin is a hormone that regulates your body’s sleep and wake cycles. “Research suggests that daily doses of melatonin can help alleviate jet lag, and that short-term usage seems to have few negative side effects,” writes Wiseman. A Cochrane review of the evidence found that melatonin is “remarkably effective” at preventing or reducing jet lag.
Obviously, though, you should consult your doctor before taking any medication.
8. If your trip is short, it might not be worth trying to adjust at all.
“Adjusting to a new local time takes about half a day per time zone if you are flying east to west, and two-thirds of a day per time zone if you are flying west to east,” writes Wiseman.
If your trip is only a few days anyway, you’ll just be getting on local time as you leave to go back home – and have to do it all over again.
Bon voyage and good luck!

Before finishing their college degree, approximately one in five women will be subject to some level of sexual assault. The volume of violence against young women seems impossible to ignore — and yet, more often than not, that’s exactly what happens.
But…what if it was a bear? What if a giant, hungry, angry bear was pounding down your door. For some women, that’s exactly what it feels like just walking to class. This video may seem silly, but its message is important for everyone to hear.
Not the greatest odds, huh? It’s time for us all to stand up and make a difference in the safety of young women and girls everywhere. Visit It’s On Us for more information and to see how you can help spread the message and save lives.

A cell phone is a must if you want to get anywhere in the world these days, so having a full battery is very important. Unfortunately, charging stations aren’t always available. So what do you do when you need your phone, but there’s no charger in sight?
If you’re as brave as this guy, you could always use train tracks to charge your device. Okay, that’s not realistic, but his experiment is worth checking out!
If you’re desperate (and I mean really, really desperate), this could be a viable solution. But if you get in trouble for doing it or you end up in the hospital, don’t say I didn’t warn you.

Over the course of two hours, these weather warriors captured a cluster of tornadoes doing things you won’t believe are real.
Outside of Ford County around Dodge City, Kansas, a group of tornadoes ripped through the countryside, doing devastating damage in the process. Check out the shocking footage they managed to capture as they trailed behind, and watch in awe as one, sadly, tears through an entire house like a knife through butter.
Nature is pretty incredible, isn’t it? Although it provides us with so much, it can also take everything away in the blink of an eye.

On April 15, 2015, researchers from E/V Nautilus sent a robot named Hercules down into the depths of the Gulf of Mexico, off the coast of Louisiana. They were exploring the biology, geology, and archeology of the ocean, and when they reached a depth of 1,962 feet, they suddenly encountered something magnificent — a sperm whale.
It is incredibly rare to have a robot meet a sperm whale at these depths, but what they captured on film for a live audience is amazing.
The population of sperm whales on Earth used to be in the millions.
Today, perhaps less than a few thousand remain due to hunting in the 19th century. For those that are still with us, however, let’s hope more footage like this gets captured. Because after seeing it, how can you not want to do everything you can to help?

Belly up! Here’s what the icy behemoths look like when they’ve had a few too many.
1. On a recent excursion to Antarctica, San Francisco-based filmmaker and designer Alex Cornell, 30, caught a rare glimpse of an iceberg’s underside.
Most icebergs’ hefty bodies are submerged under water, but occasionally they roll over, according to ScienceNews. Compared to the comprehensively white Antarctic, from a distance on their fast bouncy boat, the iceberg just looked like a piece of rock, Cornell wrote in an email to BuzzFeed.
As we got closer, it became clear that it was a pure jade iceberg. We had a naturalist onboard the zodiac boat with us, and he explained what we were seeing and why it was so exciting. To us, everything we came across was exciting (penguins! icebergs!), but this certainly stood out as a rare sight — something I had never seen before in real life, or even subsequently in photos.
3. Where do icebergs come from, anyway?
The ice giants break off from glaciers or massive ice sheets and meander along with ocean currents, according to the National Snow & Ice Data Center. So the flip occurs after the iceberg detaches from its parent, or when its ice melts unevenly and it keels over, oceanographer Louise Biddle told ScienceNews.
In a video he made about the shoot, Cornell said capturing images amid blindingly reflective surfaces is the biggest obstacle, especially because the mandatory sunglasses make it hard to review your work as you do on dry land. Of all of his projects, he never imagined a natural photo he took of ice in water would be so widely covered, he wrote on his company’s site.
4. Here’s another view of the spectacularly aquamarine ice, which steadily becomes coated with the flotsam of environmental elements.
“We were very lucky to come upon it during the short window of time before it blended back into white, after enough air, sun, and snow exposure,” said Cornell.
5. You can see even more footage of Cornell’s Antarctic shoot in his illustrative video.
Or catch more of his work (like this furry little guy) on his site or Instagram.
