As the weather warms and pollen begins its dance across the sky, some people's bodies hurl them into a storm of watery eyes, runny noses and sneezing fits. But sometimes the spring and summer months also bring bouts of tiredness. Can people with allergies also blame this on seasonal allergens? The answer is yes; there are several ways that seasonal allergies can make us feel low on energy. An allergy or allergic reaction is, by definition, a fight that the body puts up when it's faced with a foreign invader, such as pollen, said Dr. Kara Wada, an allergist and immunologist at The Ohio State University Wexner Medical Center. [Can You Learn Anything While You Sleep?] "The body expends a lot of energy in making all of the cells, proteins and all of the other substances" that build up during an allergic response, also known as inflammation, she said. This energy expenditure wears out the body and "some of the same chemical signals … in addition to fighting off what it sees as an … [Read more...] about Why Do Seasonal Allergies Make You Feel Sleepy?

If you grew up in the suburbs, you recognize it immediately: the sweet, sharp smell of someone mowing a lawn or ballfield. As it wafts into your nostrils, it somehow manages to smell exactly like the color green. But what are we really smelling when we inhale that fresh-cut grass scent? And why do we like it so much? Chemically speaking, that classic lawn smell is an airborne mix of carbon-based compounds called green leaf volatiles, or GLVs. Plants often release these molecules when damaged by insects, infections or mechanical forces — like a lawn mower. Plants manufacture slightly different forms of GLVs depending on what's happening to them, said Ian Baldwin, a plant ecologist and founding director of the Max Planck Institute for Chemical Ecology in Jena, Germany. In a 2010 study published in the journal Science, he and colleague Silke Allmann, of the University of Amsterdam, found that tobacco leaves punctured and rubbed with insect saliva released a different bouquet … [Read more...] about Why Does Freshly Cut Grass Smell So Nice?
Best answer: HDR10+ is a High Dynamic Range format that adds dynamic metadata to the HDR10 signal. Rather than set the dynamic range to a static set of numbers, HDR10+ can set and change the boundaries on the fly based on the content your screen is displaying. That means you'll have better detail and a fuller range of color, especially in scenes which display mostly light or mostly dark content. What is HDR10+? HDR10+ is an HDR (High Dynamic Range) format created by Samsung designed to expand on the HDR10 format by allowing for dynamic metadata to continuously tweak the display settings so that you're always seeing the most and best color possible. Unlike Dolby Vision — which also adds dynamic metadata to the HDR signal — HDR10+ is royalty-free and open so that any company which makes displays can adjust it to best suit its product. Even with millions and millions of colors, there will still be some that aren't in the range of your display. A display has an inherent range … [Read more...] about What is HDR10+ and why does it make the Galaxy S10 screen better?
If you want to look younger, fitness instructor Susan Forma says you need to put your face to work. The exercise technique she recommends: Face Yoga. Forma is one of only 20 certified Face Yoga instructors in the United States. She’s the only one in Florida. “I’m aware of the science behind the body, the muscles in the body,” Forma explained. “We have muscles in the face, the same as you do in the body.” Forma says just like Downward Dog can lift and tighten, practicing Face Yoga can help tone up your face and diminish fine lines around the eyes. “So, if you go to the gym to work out the muscles below your neck, why not do the ones above your neck as well,” she said. “It just makes sense, if you tighten and tone you’re going to naturally look better.” A study published in the JAMA Dermatology Journal looked at a 30-minute facial routine turning back the clock almost three years. Being aware of every movement, muscle, eye … [Read more...] about Face Yoga: Does It Make You Look Younger?
