If you answered ‘B’, you’re right! Physical touch has proven to be an excellent way to reduce one's stress. Touching and being touched can lower blood pressure and heart rate, increase immune function, relieve pain, and release feel-good endorphins. Getting a massage, hugging, holding hands, or even petting an animal are all effective ways to embrace physical touch and begin to ease anxiety and stress.

If you answered ‘B’, you’re right! According to researchers at Saint Louis University, eating cooked beets can improve running performance. Participants given a serving of baked beets before they ran went an average of 3 percent faster and shaved 41 seconds off their times in a 5-kilometer race. Beets have this effect due to nitrate, which helps muscles use oxygen more efficiently. 200 grams of baked beets, or an equivalent dose of nitrate from other vegetables, should be consumed an hour before exercise to maximize the benefits.

If you answered ‘B’, you’re right! Research suggests that exposing skin to sunlight may help reduce blood pressure and cut the risk of heart attack and stroke. Study participants sat beneath tanning lamps for 2 sessions of 20 minutes each; blood pressure was found to drop for one hour following exposure to UV rays. Far more research is needed before sunlight is recommended as an effective treatment, so those with high blood pressure should continue to take prescribed medication, maintain a healthy weight and stay physically active; proven ways to keep blood pressure under control. And, while sunlight provides health benefits, UV rays can also cause harm, so don't forget your sunscreen.

If you answered ‘A’, you’re right! A single 20-minute weight-training workout like weightlifting may boost memory. While there have been studies in the past that show months of aerobic exercise - like walking - can boost your memory, this study was different because the participants did the exercise just two days before being tested. 46 young adults viewed a series of photos. After looking at the photos, half of the group did 20 minutes of weight exercises at their personal maximum effort, the other half simply sat in the chair and let the experimenters move their legs for them. The group that exercised on their own, remembered 10% more of the photos than the group that did not.

Just the thought of spiders causes many people to cringe, but a recent study from The University of Queensland has identified compounds in spider venom that could be used to treat chronic pain in humans. 40 percent of spider venoms contain at least one compound that can block a neurological pathway related to chronic pain. This could lead to more effective treatments and could inspire a new class of potent painkiller with fewer side effects than current medications.

The absolute best defense against heat-related illnesses like heat cramps, heat exhaustion, and heatstroke is prevention. It’s a good idea to limit time outdoors during very hot weather, but if you must be outside, rest often in areas out of the sun. Other ways to stay cool are wearing light-colored, loose-fitting clothing, drinking plenty of water or fluids that don’t contain alcohol or large amounts of sugar, and cutting down on exercise outdoors during the hottest parts of the day.

Omega-3 fatty acids can be found in many different kinds of foods; many foods in the U.S. are even enriched with omega-3s. Fish like salmon or tuna are a widely-known natural source of omega-3s, but these essential fatty acids can also be found in plant form, such as in the edamame we often consume alongside our sushi! Other great plant-based sources for omega-3s include vegetable oils, walnuts, and ground flaxseed. Consuming omega-3 fatty acids can reduce the risk of heart disease and related deaths.

We've all heard that reading in dim lighting or staring at a computer screen all day can hurt our eyes or destroy our vision, but that simply isn't true. Though those activities may tire your eyes out or contribute to eyestrain, they aren't damaging. Exposure to bright sunlight, on the other hand, CAN be damaging. Your eyes are extremely sensitive to the sun's UV light and can actually sunburn. Protect your eyes by covering them with sunglasses with UV protection.

People who eat more fermented foods could have fewer symptoms of social anxiety. These foods contain healthy bacteria called probiotics. Probiotics improve the environment in the gut, and microorganisms in the gut can actually influence the mind! Researchers found that those who displayed neuroticism in addition to social anxiety disorder experienced the greatest benefit from fermented foods. Further testing is needed to prove that fermented foods directly cause a reduction in social anxiety, but if you'd like to test it out, yogurt, sauerkraut, pickles, tempeh, and kimchi are all great options.

Listening to extreme music such as heavy metal can actually have a calming effect on people, having the same effects as a warm hug! A recent study showed that when fans of extreme music were angry, they liked to listen to music that matched their anger. The music let participants fully explore the emotions they were feeling, but also left them feeling more positive and inspired.

Though there is no harm in taking a vitamin C supplement if you feel a cold coming on, it won't prevent a cold from developing. Taking vitamin C only helps to treat colds in people whose bodies have very low levels of the vitamin, such as people who live in cold climates. Large doses of vitamin C may keep an existing cold from lasting as long, but taking more than 500mg is not helpful - a higher dosage simply can't be absorbed by the body.
