Why Does Sunlight Damage Our Skin?

If you believed the headlines, just about everything, from cell phones to coffee, causes cancer. Most of those headlines are overblown, at best, but there are still plenty of carcinogens out there. Some of these, like smoking, are avoidable. Others, like sunlight, are a little trickier. The video above from the American Chemical Society explains how the sun can damage us and why we’d be wise to take precautions.   

Given its constant and almost mundane presence in our lives, it’s easy to forget that the Sun is a star, but it is. And like all the other stars, it gives off intense radiation (what we usually call sunshine). Fortunately, our planet is surrounded by a marvelous natural shield: the ozone layer. Gases in the atmosphere bear the brunt of the Sun’s force, allowing just a trickle of ultraviolet radiation through. Of course, “a trickle” is relative. Those rays are still strong enough to burn our skin and damage our DNA if we’re not careful. 

Sun exposure is kind of like crushing a cookie in your fist; there’s not much you can do to fix it once the damage is done. But you can take steps to protect yourself now and decrease future harm. Wear sunscreen every day (yes, even in the winter), indoors and out, and reapply every two hours. We know you’re sick of hearing it now, but you’ll thank us later.

The Hidden Benefits of Your Health Insurance Plan

When we talk about health insurance, it’s usually in the context of a complaint. While it’s true that insurance companies often fight tooth and nail to keep their financial exposure limited, they’re also making moves to offer benefits beyond standard health care—and you might not even know about these perks.

A prime example is the recent trend for companies to offer a discount savings card on groceries. United Healthcare, Humana, and Medica are just a few of the insurers who have issued cards that can be used for an instant price reduction when checking out at participating stores. The catch? The programs typically cover healthy or organic foods. Along with discounted gym memberships, the benefit is an effort to keep policy holders fit and—at least theoretically—to reduce the need for medical interventions.

If you’re surprised to hear about it, you’re not alone. Here are some other programs offered by the nation's largest insurance companies that you might be missing out on. (Bear in mind that each company has various tiers of coverage and not all perks may apply to all levels.)

UNITED HEALTHCARE

The company’s Healthy Savings program for groceries allows shoppers to save on select items that change on a weekly basis. Each Sunday, the cards will recognize between $40 and $50 in deals on healthier grocery options. It’s only good at participating retailers, including Shop ‘n’ Save, Giant, and others. You can search for locations on their website.

Through UnitedHealth Allies, the company also offers discounts on weight loss programs like NutriSystem and Jenny Craig, as well as gym memberships and even active footwear [PDF].

CIGNA

The Northeast-based insurance company provides an umbrella discount service, Healthy Rewards, that offers savings on eye exams and up to 25 percent off alternative health therapies like acupuncture, chiropractic, and massage appointments [PDF]. They also offer fitness membership discounts. More information can be found at MyCigna.com.

AETNA

It’s hard to know what the pending acquisition of Aetna by pharmacy giant CVS will mean for health care perks moving forward. Currently, the company offers discounted memberships and trial passes to more than 10,000 gyms nationally, as well as discounts on home fitness equipment like treadmills [PDF]. You can also find discounts on meal home delivery subscriptions. Logged-in members can go to the Aetna website and select “Health Programs” then “Discounts” to determine your eligibility.

ANTHEM BLUECROSS

In addition to savings on groceries, gym memberships, and weight loss programs, Anthem BlueCross offers savings for members on DNA ancestry kits, pet insurance, and even baby-proofing.

HUMANA

Humana offers an impressive array of “lifestyle discounts” that range from basic wellness perks to teeth whitening, identity theft services, and 15 percent off in-network LASIK procedures. They also offer discounts on over-the-counter medications like Claritin and Advil. You can register at MyHumana.com to find out more.

Bose's New 'Sleepbuds' Are Designed to Help You Doze Off Faster

If you’re the kind of person who can’t fall asleep without the whir of a fan or some other ambient noise in the background, then Bose has a product for you. As spotted by The Verge, the audio equipment company’s new wireless noise-masking Sleepbuds are designed to fit comfortably into your ears and help you doze off faster.

Unlike other Bose earbuds—and, well, most headphones in general—the Sleepbuds don’t actually play music or allow audio to be streamed from external devices. Instead, they come equipped with 10 soothing audio tracks, including brown noise, rain, ocean waves, a running stream, and more.

The earbuds aren’t noise-canceling, but their audio tracks are specifically engineered to mask certain outside sounds like traffic and, perhaps most impressively, your partner’s snoring. The rechargeable battery lasts for 16 hours, and at just 1 centimeter in width and height, they’re Bose’s tiniest product yet.

For early risers whose partners like to sleep in, the Bose Sleep app can sound off an alarm in your ear that only you can hear. The app can also be used to adjust your sleep settings, including your noise of choice, volume levels, and how long you want the sound to play for.

Bose spent a couple of years developing the product and raised over $450,000 in an Indiegogo campaign to help improve the Sleepbuds by getting backers to test them out and provide feedback. The Sleepbuds are now available for purchase on Amazon for $249.
