A Chemical in Bed Bug Poop Might Be Making You Feel Sick

Bed bugs can give you nasty bites and a lifetime of nightmares, but scientists have long wondered if the creepy parasites can pass diseases to their hosts. For years, the general consensus was no: Unlike ticks, mosquitos, and other insects that are known to feast on human blood, bed bugs aren't packing any harmful pathogens in their bites. Yet according to a new study, spotted by Gizmodo, the bugs don't need to nibble on us to make us sick. Histamines in their poop might be aggravating our immune systems.

For their study, recently published in the journal PLOS One, scientists at North Carolina State University tested the dust in a bed bug-infested apartment complex. They found that samples from some infested homes had histamine levels 20 times higher than those without bed bugs. This was still the case three months after the buildings had been treated by exterminators.

Histamine is a chemical compound produced by our bodies. In small amounts, it works as a vital part of our immune system. It's activated in the presence of allergens, irritants, and pathogens. Say a puff of dust goes up your nose: Histamine is what prompts your body to sneeze it out. It's also the culprit behind the watery eyes, runny nose, and itchy skin you might experience during an allergy attack (which is why you might take an antihistamine to calm these symptoms).

But we're not alone in our ability to produce histamine. Recent research has shown that the chemical is present in bed bug feces. When the insects poop, they spray histamines into the same air that homeowners breathe. A few whiffs of the stuff is likely nothing to worry about, but scientists are concerned about the effects environmental histamine can have on people over an extended period of time. The chemical compound can cause allergic reactions on its own and possibly make us more vulnerable to existing allergens. The implications are especially serious for people with asthma.

"Dermal, nasal, or respiratory responses (e.g. bronchial reactivity) to histamine in clinical tests suggest that exposure to histamine in the environment would constitute a significant health risk, although information on environmental exposure is limited," the study authors write.

For now, scientists can do nothing but speculate on what these results might mean for public health. Humans are prepared to treat only histamine that's produced by our own bodies, and dealing with the effects on histamine spread by bed bugs is uncharted territory for doctors and scientists. How exactly bed bugs obtain the chemicals in the first place is also unclear, but researchers suspect that it's a combination of the blood they suck from us and histamine they make on their own as a type of pheromone, indicating to other bed bugs that a place is safe to invade.

Following this study, the North Carolina State scientists plan to conduct more intensive research on the impact histamine produced by bed bugs is having on the people who live with it. While the best way to eradicate histamine in bed bug poop is still a mystery, there are plenty of ways to deal with the bugs themselves if you suspect you have an infestation.

10 Surprising Uses for Leftover Bananas

Bananas are practically the perfect fruit. They’re high in potassium and vitamins. They don’t need to be washed or sliced. They make a great healthy snack, but you can also put them in bread, ice cream, pie, and pancakes. What’s not to love?

Well, there’s one tiny problem—they go bad quickly. Bananas produce a large amount of a gas called ethylene, which causes fruit to ripen faster, meaning that there's a small window to enjoy them. Just because a bunch of bananas is past its prime doesn’t mean they can’t be used, though. Here are a few of the things you can do with ripe bananas.

1. TREAT BUG BITES.

Pressing the inside of a banana peel onto a bite from a mosquito or other insect for a few minutes is a surprisingly simple way to quell itching. In fact, some studies have shown that banana peels can help reduce irritation and inflammation [PDF, PDF]. The use of banana peels to treat inflammation is said to be an ancient Chinese remedy, but people around the world swear (with varying degrees of evidence) by the fruit’s ability to soothe poison ivy rashes, psoriasis, sunburn, and other skin maladies.

2. REMOVE A SPLINTER.

If tweezers aren’t getting that pesky splinter out, try a banana peel instead. Tape a piece of the peel onto the affected area (with the soft, inner side of the peel facing down) and leave it in place for about 10 minutes. The enzymes in the fruit should help to force the splinter out.

3. ATTRACT BUTTERFLIES AND HUMMINGBIRDS.

Once a common sight in the U.S., monarch butterflies are now difficult to spot. Their population has dwindled due to loss of habitat, but you can improve your chances of seeing them by placing an overripe banana out in your garden. They’re just soft and sweet enough for butterflies to enjoy (make sure to remove the bananas before you go to bed, though, or else you'll have animals like raccoons in your garden). You can also place bananas near a hummingbird feeder to attract fruit flies, which the birds feast on.

4. FERTILIZE PLANTS.

While you’re out in the garden feeding the birds and butterflies, give your plants some love, too. When cut-up banana peels are buried, they enrich the soil with nutrients and help nourish plants. You can also wrap a banana peel around a tomato plant to create a natural fertilizer.

5. POLISH LEATHER AND SILVER.

If you’re in need of a quick shoe shine, reach for the fruit bowl. The potassium in bananas make them a great, quick tool for polishing your leather. Simply buff the leather with the inside of a banana peel, and use a cloth to wipe it clean. The same technique can also be used to polish silver (though some recommend blending the banana peels into a paste and putting that on a cloth for polishing).

6. MAKE SMOOTHIES, SANS ICE.

Bananas have long been a staple in smoothies, but what if you have a whole bunch that’s about to go bad? Instead of throwing them out, stick them in the freezer. You can pull one out any time you get a smoothie craving, and since it’s frozen, you won’t even need to add ice.

7. MAKE NATURAL BEAUTY PRODUCTS.

Beauty products don’t have to be expensive. Bananas are a great ingredient in DIY hair treatments and skin exfoliants. The amino and citric acids help protect hair from damage and keep it shiny. There are a few different recipes you can try, some of which combine banana with avocado, yogurt, egg, and other ingredients. Rubbing the inside of a banana peel onto your face (seriously, try it) is also said to brighten your skin, fight acne, and reduce puffiness around your eyes.

8. PREVENT INFLAMED MUSCLES.

A recent study published in the journal PLOS One found that competitive cyclists who had consumed a banana instead of a sugary drink or water had less inflammation following their workout. Although other physicians cite the benefits of consuming bananas post-workout, the sample for this particular study was small—only 20 cyclists—and was funded by Dole Foods (although they had no role in any part of the study), so you might not want to swap out ibuprofen for bananas just yet—especially since the lead author told The New York Times that the banana led to “quite a bit of bloating,” so maybe best to not experiment on race day.

9. REPAIR A SCRATCHED DVD.

CDs and DVDs may be a dying technology, but many people still have a few lying around at home. If you have any discs that are scratched, you can try using toothpaste and banana to salvage them. First, rub toothpaste into the scratches with a cloth. Wipe it off, then rub a piece of banana onto the disc in a circular motion. Do the same thing with the banana peel and clean the disc with window cleaner. Whether or not this trick works will depend on how badly the disc is scratched, but it’s worth a shot!

10. TRY OUT SOME NEW RECIPES.

If a bunch of bananas is too ripe for your liking, try repurposing the fruit. There are hundreds of recipes that call for overripe bananas. The Food Network's Canadian site lists 83 recipes on its website, including chocolate chip banana pancakes, a peanut butter and banana oatmeal smoothie, and slow cooker banana upside down cake.

Delta and Equinox Teamed Up to Create Jet Lag-Fighting Workouts

When traveling across time zones, jet lag is practically unavoidable. The temporary condition disrupts your internal body clock, making you feel groggy and irritable.

Hitting the town once you land at your destination, let alone working out, may seem out of the question. However, exercise is one of the best things you can do for your jet-lagged body, and you'll feel much better afterward.

Delta Air Lines and Equinox Fitness have teamed up to create a series of equipment-free workouts that specifically target jet lag, according to Travel + Leisure. Three videos guide viewers through three rounds of exercise, each targeting a different region—upper body, lower body, and core.

Viewers can select one round (or more) and do each of the featured moves for one minute, then repeat each move two more times. If doing all three rounds, it would take about 30 minutes to complete the main portion of the workout. A cool-down video has also been created to take viewers through some guided stretches.

The workout is low-impact and aims to reduce stiffness and wake up your senses. It’s recommended that the workout be done 12 to 24 hours after landing.

"This is when your body is most vulnerable and susceptible to time zone changes, so working out in this time can resync your circadian rhythm, lower your cortisol levels, and impact circulation and mobility,” Equinox group fitness manager Dana McCaw tells Travel + Leisure.

The workout videos, which are posted on YouTube, can be watched below:
