How Do Muslims Fast for Ramadan if There's No Sunset?

Earlier this month, many Muslims all over the world began their observance of Ramadan, the month of daily fasting that serves to train believers' spiritual and physical discipline and self-control. Between dawn and sunset, observers refrain from all food and drink, as well as other physical pleasures like cigarettes and sex.

In some parts of the world, however, this is easier said than done. Some areas have exceptionally long days during the summer. Scandinavia, Canada, Russia, and Alaska all have cities above the Arctic Circle, where the sun literally does not set for weeks at a time. Since Ramadan is tied to the lunar calendar and moves annually, these places will have the opposite problem during winter Ramadans where the sun won't rise for more than a month.

What's a Muslim in Longyearbyen, Norway or Barrow, Alaska supposed to do when there's no sunrise or sunset to guide their fasting? Starve? Fly south for Ramadan?

With no central authority or leadership like the Roman Catholic Pope to give guidance, different Muslim scholars and organizations have to come up with their own ways of dealing with the problem, and many seem to have convened on one solution: ignore the sun's local position and follow more reasonable sunrise and sunset times from another place.

The Islamic Center of Northern Norway, for example, issued a fatwa—a decision given by a scholar of Islamic law or other Muslim judicial authority—that gives local Muslims the option of following the fasting hours of the holy city of Mecca when the local fasting day exceeds 20 hours. The Assembly of Muslim Jurists of America made a similar ruling that said that Muslims living at extreme northern points of Alaska use the sunrise and sunset times of another part of the country where "day is distinguishable from night." The Council of Senior Scholars in Saudi Arabia likewise decided that Muslims "in a land in which the sun does not set during the summer and does not rise during the winter" should set their fasting times based on "the dawn and sunset each day in the closest country in which night can be distinguished from day."

One Muslim has gone even further afield from the religion's Arabian homeland than some snowy arctic village. In 2007, Malaysian astronaut Sheikh Muszaphar Shukor had to figure out how to fast for Ramadan while orbiting the Earth every 90 minutes and going through 16 day/night cycles every 24 hours. To advise in his fasting and daily prayers, Malaysia's Department of Islamic Development and its National Fatwa Council put their best minds together and came out with a booklet called "Guidelines for Performing Islamic Rites at the International Space Station." Shukor was given the option to defer his fasting until his return to Earth or follow the sunrise and sunset times of Baikonur, Kazakhstan, where Shukor was launched into space.

What's the Difference Between Cement and Concrete?

Picture yourself walking down a city block. The sidewalk you follow may be obscured by shuffling feet and discarded gum, but it’s clearly made from something hard, smooth, and gray. What may be less clear is the proper name for that material: Is it concrete or cement? Is there even a real difference between the two words?

Though they’re often used interchangeably, concrete and cement describe different yet related elements of the blocks, flooring, and walls that make up many everyday structures. In simple terms, concrete is the name of the gray, gritty building material used in construction, and cement is an ingredient used in concrete.

Cement is a dry powder mixture that looks much different from the wet stuff poured out of so-called cement trucks. It’s made from minerals that have been crushed up and mixed together. Exactly what kind of minerals it’s made from varies: Limestone and clay are commonly used today, but anything from seashells to volcanic ash is suitable. After the ingredients are mixed together the first time, they’re fired in a kiln at 2642°F to form strong new compounds, then cooled, crushed, and combined again.

This mixture is useless on its own. Before it’s ready to be used in construction projects, the cement must be mixed with water and an aggregate, such as sand, to form a moldable paste. This substance is known as concrete. It fills whatever mold it’s poured into and quickly hardens into a solid, rock-like form, which is partly why it’s become the most widely-used building material on Earth.

So whether you’re etching your initials into a wet sidewalk slab, power-hosing your back patio, or admiring some Brutalist architecture, you’re dealing with concrete. But if you ever happen to be handling a chalky gray powder that hasn’t been mixed with water, cement is the correct label to use.

Why Do You Stop Feeling Tired As Soon As You Climb Into Bed?

There are few situations more frustrating: After a day spent nodding off at your desk, on the train, and on your couch, you suddenly can't sleep the moment you crawl into bed. It's not that you aren't tired or have insomnia, necessarily. Like a curse designed just to torture you, the sleeplessness only seems to occur when you're in your own bed at home, a.k.a. the place where you'd prefer to do your sleeping.

This maddening problem isn't in your head. According to TIME, many people have more trouble falling asleep in their own beds than they do elsewhere thanks to a phenomenon called learned or conditioned arousal. Conditioned arousal develops when you inadvertently train your body to associate your bed with being awake. In many cases, this results from doing stimulating activities in bed. For instance: If you like to slip under the covers and spend 40 minutes watching Netflix before closing your eyes, you're teaching your brain that your bed isn't for sleeping. That means the next time your head hits the pillow, your body will respond by preparing for the next episode of Friends instead of releasing the chemicals that help you fall asleep. The same goes for scrolling through apps, eating, and even reading in bed.

Doing things that aren't sleeping in bed isn't the only way to develop conditioned arousal. If there are other factors keeping you up at night—like thoughts about your day, or that cup of coffee you had at 8 p.m.—they can lead to the same result. Your brain starts to associate being in bed with tossing and turning all night, so even if those mental and physical stimulants go away, the muscle memory of being awake in bed remains.

Conditioned arousal is a vicious cycle that can't be broken in one night. The only way to manage it, according to the American Psychological Association (APA), is to minimize behaviors that contribute to poor sleep habits and to reserve your bed for sleeping (though sex is OK, according to the APA).

If you're a nighttime scroller, browse apps in a different room before getting into bed, or skip checking your phone at the end of the day altogether. When you spend more than 20 minutes struggling to fall asleep in bed, get up and move to a different part of the house until you get sleepy again; this will stop your brain from strengthening the association between your bed and feeling restless. The results won't be instant, but by sticking to a new sleep routine, you should eventually train your body to follow healthier patterns.

Of course, combating conditioned arousal alone isn't always effective. In people with conditions like anxiety and insomnia, intrusive thoughts and genetic factors can prevent them from falling asleep even under ideal circumstances. In such cases, the help of a medical professional may be required to sleep more soundly.
