Halloween is all about embracing the supernatural, but science shouldn't entirely fall by the wayside during the spookiest of holidays. Here are eight ways it can actually improve your holiday, from making trick-or-treating easier to fooling your brain into thinking you're eating tasty treats even though you're nibbling on candy cast-offs.

1. SLOW DOWN THE DECOMPOSITION OF YOUR JACK-O'-LANTERN.

You don't have to be an expert gardener to keep your jack-o'-lantern looking fresh all Halloween season long. While scouting out pumpkins, pick hard, unblemished ones and steer clear of those with watery dark spots. These splotches indicate frost damage.

Hold off on carving until right before Halloween so your gourds won't rot—but if you can't resist, try squirting their exteriors with lemon juice after you're done slicing and dicing. This inhibits pumpkin enzymes, which react with oxygen and cause browning. A light misting of bleach solution will help keep fungus at bay. Some apply vegetable oil or Vaseline to prevent shriveling and drying. We experimented with various techniques in a Facebook video—check out our results.

For extra TLC, you might even want to bring your jack-o'-lanterns in at night if temperatures dip; if you live in a hot and humid area, extend its life by placing it in the fridge overnight. Try using glow sticks or LED lights instead of flesh-singeing candles.

2. USE TECH TO PLAN THE ULTIMATE (AND SAFEST) TRICK-OR-TREATING ROUTE.

Thanks to technology, trick-or-treaters (and their hungry adult companions) can now scout out which neighbors are doling out the best candy and which are sticking with Tootsie Rolls, bubble gum, and toothbrushes. Simply download the app for Nextdoor, a neighborhood-based social network, to check out an interactive "treat map" that lets users tag whether their home is handing out treats, and what that treat is.

Since safety is far more important than sugar, guardians should also consider adding a tracking app to their arsenal come Halloween, especially if their kid's venturing out alone. The Find My Family, Friends, Phone app gives the real-time locations of trick-or-treaters, provides alerts for when they turn home, and also comes with a "panic" button that provides emergency contact details when pressed.

3. OPTIMIZE YOUR CANDY'S FLAVOR—EVEN THE DISAPPOINTING LOOT.

Not crazy about this year's Halloween loot? Fool yourself into thinking those black licorice pieces and peanut chews taste better than they actually do by eating them after you scarf down the chocolate and Sour Patch Kids. According to a 2012 study published in Psychological Science, being aware that these items of candy are your very last candies actually tricks the brain into appreciating them more (and thus thinking they're tastier than they really are).

Meanwhile, a 2013 study from the same journal found that creating a candy-eating ritual enhances flavor and overall satisfaction. Nibble the ridged edges off a Reese's peanut butter cup before tackling the creamy center, sort the M&Ms by color, and take your time unwrapping a chocolate bar.

4. CRANK UP YOUR HOUSE'S SPOOKY FACTOR WITH SCIENCE.

5. EAT HEART-HEALTHY HALLOWEEN CANDY—IT'S GOOD FOR YOU! (KIND OF.)

Halloween candy isn't always bad for you. While shopping for this year's trick-or-treat bounty, steer clear of sugary confections and milk chocolate mini-bars. Opt for dark chocolate treats instead. Research suggests that our gut microbes ferment the antioxidants and fiber in cocoa, creating heart-healthy anti-inflammatory compounds. Plus, dark chocolate or cocoa also appears to help lower blood pressure for people with hypertension, decrease bad cholesterol, and stave off cardiovascular disease and diabetes, among other benefits.

6. USE DATA SCIENCE TO GIVE OUT CANDY THE NEIGHBORHOOD KIDS ACTUALLY LIKE.

Thanks to data science, you can make sure you're giving out the best treats on the block. Bulk candy retailer CandyStore.com combed through 10 years of data (2007 to 2016, with a particular focus on the months leading up to Halloween) to gauge America's top-selling sweets. They created an interactive map to display their results, which includes the top three most popular Halloween handouts in each state, as well as in Washington, D.C. Be prepared for plenty of stoop-side visitors and adorable photo opps.

7. TAP INTO KITCHEN CHEMISTRY TO BAKE BETTER HALLOWEEN TREATS.

Cooking is essentially chemistry—and depending on your technique, you can whip up chewy, fluffy, or decadent Halloween treats according to taste.

Folding chunks of chilled butter into your dough will give you thick, cake-like cookies, as will swapping baking soda for baking powder. Curious why? When butter melts, its water converts into gas, which leaves lots of tiny holes. If the butter flecks in question are colder and larger, they'll leave bigger air pockets. As for the baking powder, it produces carbon dioxide gas both when it's mixed into the dough and when it's heated up. For an extra boost in texture, you can also try adding more flour.

Prefer chewier cookies? Start out with melted butter in the dough, and stick with plain old baking soda.

And for extra fragrant and flavorful baked goods, opt to use dark sugars—like molasses, honey, and brown sugar—as they're filled with glucose and fructose instead of plain old sucrose. As cookies bake, they undergo two processes: caramelization, in which the sugar crystals liquidate into a tasty brown liquid, and then the Maillard reaction, which is a chemical reaction between the dough's proteins and amino acids (flour, egg, etc.) and the reducing sugars.

8. USE MIND TRICKS TO ENJOY HAUNTED HOUSES WITHOUT GETTING TOO SCARED.

Halloween can be tough for people with anxiety or low thresholds for fear. While visiting a haunted house or watching a scary movie, remember to take deep breaths, which fends off the body's flight-or-fight response, and re-frame your anxiety as "excitement." It's also a good idea to schedule spine-chilling activities after an activity that triggers feel-good endorphins—say, after a walk to check out your neighbors' awesome Halloween displays.

9 Things You Should Keep in Mind Around Someone Observing Ramadan
iStock

To mark the ninth (and most holy) month in the Islamic calendar, Muslims around the world observe Ramadan. Often compared to Lent in Christianity and Yom Kippur in Judaism, Ramadan is all about restraint. For one month, Muslims observing Ramadan fast during the day and then feast at night.

By abstaining from food and water (as well as sex, smoking, fighting, etc.) during daylight, Muslims strive to practice discipline, instill gratitude for what they have, and draw closer to Allah. To be respectful and not annoy observers, here are nine things you should never say or do to someone observing Ramadan.

1. DON'T JOKE ABOUT WEIGHT LOSS.

Although it might be tempting to joke about Ramadan being a good excuse to lose weight, it is a time for spiritual reflection and is a serious matter. Observers undertake the challenge of fasting for religious and spiritual reasons rather than aesthetic ones. And, once the sun sets each night, many Muslims prepare a hearty iftar (the meal that breaks the fast) of dates, curries, rice dishes, and other delicious foods. The suhoor (the pre-dawn meal) is often fresh fruit, bread, cheese, and dishes that are high in fiber and complex carbohydrates. So the idea of a cleanse is pretty far from their minds.

2. DON'T MAKE ASSUMPTIONS.

There are approximately 1.8 billion Muslims around the world, but not all of them observe Ramadan the same way. Although most observant Muslims fast for Ramadan, don't assume that every Muslim you meet has the same methods, traditions, and attitudes towards fasting. For some, Ramadan is more about prayer, reading the Qur'an, and performing acts of charity than merely about forgoing food and drink. And for those who may be exempted from the daily fasting, such as pregnant or nursing women, the elderly, or those with various health conditions, they might not appreciate the reminder from nosey busy-bodies that they aren't participating in the traditional way.

3. SAY "RAMADAN MUBARAK" INSTEAD OF "HAPPY RAMADAN."

Rather than wishing someone a happy Ramadan, being more thoughtful with your choice of words can show that you understand and respect the sanctity of their holy month. Saying "Ramadan Mubarak" or "Ramadan Kareem" are the traditional ways to impart warm wishes—they both convey the generosity and blessings associated with the month. The actual party comes after Ramadan, when Muslims celebrate Eid al-Fitr, an up to three-day festival that involves plenty of food, time with family, and gifts.

4. DON'T BE A FOOD PUSHER.

Even if the idea of not eating or drinking all day might be unfathomable to you, don't push food onto anyone observing Ramadan. While fasting all day for a month can cause mild fatigue, dehydration, and dizziness, don't try to convince participating Muslims to eat or drink something—they are fully aware of any side effects they may feel throughout the day. Instead, be respectful of their decision to fast and offer to lend a hand with something like chores, errands, or anything unrelated to food.

5. ACCEPT THAT WATER ISN'T ON THE MENU.

Muslims who observe Ramadan don't sip any liquids during daytime. No water, coffee, tea, or juice. Zilch. Going without water is even harder than going without food, so be aware of the struggle and accept it. It's all part of the sacrifice and self-discipline inherent in Ramadan.

6. RESPECT PEOPLE'S PRIVACY.

Some Muslims choose not to fast during Ramadan for medical or other personal reasons, and they may not appreciate being badgered with questions about why they may be eating or drinking rather than fasting. Children and the elderly generally don't fast all day, and people who are sick are exempt from fasting. Other conditions that preclude fasting during Ramadan are pregnancy, breastfeeding, and menstruation (although, if possible, people generally make up the days later).

7. BE MINDFUL OF ENERGY LEVELS.

Eschewing food and drink for hours at a time can cause lethargy, so be aware that Muslims observing Ramadan may be more tired than usual. Your Muslim friends and coworkers don't stop working for an entire month, but they may tweak their schedules to allow for more rest. They may also stay indoors more (to prevent overheating) and avoid unnecessary physical activity to conserve energy. So, don't be offended if they aren't down for a pick-up game of basketball or soccer. We can't all be elite athletes.

8. DON'T OBSESS OVER FOOD AND HUNGER.

One of the worst things you can do to someone on a new diet is to obsess over all the cheeseburgers, pizza, and cupcakes they can't have. Similarly, most Muslims observing Ramadan don't want to have in-depth conversations about all the food and beverages they're avoiding. So, be mindful that you don't become the constant reminder of how many hours are left until sundown—just as you shouldn't joke about weight loss, you shouldn't call attention to any hunger pangs.

9. DON'T BE AFRAID TO EAT YOUR OWN FOOD.

Although it's nice to avoid talking about food in front of a fasting Muslim, don't be afraid to eat your own food as you normally would. Seeing other people eating and drinking isn't offensive—Muslims believe that Ramadan is all about sacrifice and self-discipline, and they're aware that not everyone participates. However, perhaps try to avoid scheduling lunch meetings or afternoon barbecues with your Muslim colleagues and friends. Any of those can surely wait until after Ramadan ends.

9 Common Misperceptions About Religious Observances

Religion can be confusing. Not only do many religions have similar philosophies and holidays, for many of the world's most widely practiced religions, the details for observing certain holidays or rites can differ based on location, denomination, or modernization. And for those who are less familiar with a particular religion, the details can be easy to overlook. From Ramadan to Advent to Bathing the Buddha, we break down nine common misconceptions surrounding popular religious observances.

1. WHAT'S WRONG: RAMADAN IS A HOLIDAY.

"In American thinking, we think of [Ramadan] as a holiday because that's the way we associate important religious dates as holidays," Vali Nasr, a professor of international politics at Tufts University, told NPR. "It's not a holiday in the sense that life goes on. The last day of the holy month, which is Eid ul-Fitr, is a holiday and there are periods in between that are holidays. But as a whole, it's not a holiday."

Ramadan is the ninth month in the Islamic calendar (which is a lunar calendar, which explains why the date moves in relation to the Gregorian calendar). It's significant because the Qur'an was first revealed, and the gates of Heaven are opened and the gates of Hell are closed, during this time.

Lailat al Qadr is the actual night of the revelation of the Qur'an, and praying on that night is said to be "better than a thousand months." But no one knows what night it actually was, only that it was probably in the last 10 days of the month. As such, the last 10 days of Ramadan are generally treated as special days.

The main holiday associated with Ramadan is Eid al-Fitr (or Eid ul-Fitr), which marks the end of the month and the end of fasting.

2. WHAT'S WRONG: THE RAMADAN FAST IS ALL ABOUT NOT EATING.

In the West, much of the attention is focused on how, for the month of Ramadan, Muslims don't eat or drink from sunrise to sunset. But that's only part of the story—Muslims are also supposed to abstain from sex, fighting, smoking, bad thoughts, and sometimes even TV during the time of the fast. According to Nasr, "It's a period of spiritual reflection," of which not eating is a part.

But not all Muslims abstain from eating during Ramadan. Some Ismaili Muslims abstain from eating on only a handful of days throughout the year, and during Ramadan focus instead on those other forms of fasting.

3. WHAT'S WRONG: THE RAMADAN FAST IS ALWAYS FROM SUNRISE TO SUNSET.

The majority of the time, this is true. But for Muslim communities in the far north, fasting from sunrise to sunset can be a problem—in the summer, the sun might not set for days or weeks, and in the winter the sun may never rise. Some tough it out, while others follow the time of the nearest major city, nearest Muslim country, or Mecca.

4. WHAT'S WRONG: ADVENT STARTS ON DECEMBER 1.

Virtually all the Advent calendars available in the market start on December 1, but this is only rarely correct. Advent actually starts on the Sunday nearest the Feast of St. Andrew, which is November 30. It's believe that the misconception can be traced back to a German man named Gerhard Lang. Lang, inspired by the Advent calendars his mother made him as a boy, began mass producing the calendars in the early 20th century; he eventually decided to standardize the calendar as starting at December 1.

5. WHAT'S WRONG: LENT IS THE 40 DAYS BETWEEN ASH WEDNESDAY AND EASTER.

According to the Archdiocese of New Orleans, "Strictly speaking, Lent ends with the beginning of the Triduum on Holy Thursday. The Ordo [the official book that details such issues] notes: 'Lent runs from Ash Wednesday until the Mass of the Lord's Supper exclusive on Holy Thursday.'" [PDF]

The change to Holy Thursday only dates to the 1960s and is only true for Roman Catholics (who point out that a distinction is made between liturgical Lent and the Lenten fast), but even among other Western churches the definition of Lent being the 40 days between Ash Wednesday and Easter isn't quite right. There are actually 46 days between Ash Wednesday and Easter (not including Easter, as traditionally Lent ended on Easter Saturday). The other six days are on Sundays, when fasting is forbidden.

6. WHAT'S WRONG: THE HAJJ IS THE WORLD'S LARGEST RELIGIOUS GATHERING.

Every year in the 12th month of the Islamic calendar, 2 to 3 million Muslims gather for the Hajj, or the pilgrimage to Mecca. Despite that number, it is not the largest religious gathering in the world. Kumbh Mela brings Hindus together every three years at one of four alternating sites, with the main Kumbh Mela occurring in Allahabad; In 2013, it counted approximately 120 million people. According to the BBC, the story of Kumbh Mela is that gods and demons fought over a pitcher of nectar and a few drops fell on each of the four cities that now host the festival, and during the festival the water becomes the nectar.

7. WHAT'S WRONG: BATHING THE BUDDHA IS A UNIVERSAL CELEBRATION.

One of the most well-known Buddhist celebrations in the West is Vesak (or Wesak), and one of the most well-known components of the day is Bathing the Buddha, where water gets poured over the Buddha to purify the mind.

But in reality the day is more complex than that. Vesak is a day that commemorates the birth, enlightenment, and death of the Buddha in Theravada Buddhism. But Mahayana Buddhists view these three events as happening at three separate times, with only the Buddha's birthday occurring the same time as Vesak. In modern Western cities that have multiple Buddhist groups, the Mahayana tradition of Bathing the Buddha often gets combined with the Theravada celebration of Vesak, so much so that one Theravada Buddhist writing for the Huffington Post noted that he had never even heard of the Bathing the Buddha tradition as part of Vesak before college.

8. WHAT'S WRONG: RELIGIOUS OBSERVANCES ARE ALWAYS SPECIFIC TO THE RELIGION.

While most of the time a religious holiday is exclusive to its religion, there are certain festivities that span across religions. The Muslim day of Ashura originated when Mohammed arrived in Medina and saw the Jews fasting in honor of Moses. Mohammed then ordered a fast as well. Today, scholars debate whether the Jews of Medina were celebrating Passover or Yom Kippur, but Ashura was originally based on a Jewish holy day.

9. WHAT'S WRONG: ALL MEMBERS OF A RELIGION CELEBRATE THE SAME HOLIDAYS.

Just as some holidays can spread across multiple religions, some holidays are not universally followed within the religion. Quakers, which are a denomination of Protestant Christians, have traditionally not celebrated Christmas or Easter because they consider every day a holy day. Traditionally, the people of Kerala in the south of India don't view Diwali as a major celebration, for reasons that are debated. And on the flip side, groups within a religion often have their own holidays, such as the Old Believers (a group of Eastern Orthodox Christians who split from the main branch) who celebrate holidays such as the Transfer of the Relics of St. Nicholas, commemorating the movement of the relics from Turkey to Italy.
