More Than 75 Percent of Americans Don't Exercise Enough

If you're like the majority of Americans, you're probably not exercising enough. According to a new study from the Centers for Disease Control and Prevention (CDC) reported by Fortune, less than a quarter of U.S. adults met the recommended amount of weekly aerobic and muscle-building activity between 2010 and 2015 [PDF].

The leisure exercise guidelines the CDC referenced were set in 2008: They suggest that adults complete at least 150 minutes of "moderate-intensity aerobic physical activity" a week, 75 minutes of "vigorous-intensity aerobic physical activity," or a mix of the above. Just 22.9 percent of adults ages 18 to 64 met this criteria. For men, the national average was 27.2 percent, and for women, it was 18.7 percent.

The CDC study, which was released June 28, also broke down exercise habits by state. Colorado came in as the most active state, with 32.5 percent of residents meeting the exercise standards—nearly 10 percent more than the national average. People in Mississippi were the least likely to work out enough, with the average there coming out to just 13.5 percent.

While the CDC's study only looked at leisure exercise, it's possible the results would have been different if it had also looked at the physical labor we do for our jobs, or just the walks we take on our commutes. The CDC points out that people with physically demanding jobs or those who bike or walk to get around may be less likely to exercise in their free time, even if they're technically more active overall than the people who do.

No matter how you compare to the CDC's standards, it never hurts to find room in your schedule for more exercise. Not only does working out have physical health benefits, but it can improve your mental health as well by boosting your energy and helping you fight stress. Here are some tips for creating a fitness routine if you don't have one already.

Airports Are Fighting Traveler Germs with Antimicrobial Security Bins

If you plan to do any air travel this summer, chances are you'll be negotiating a path riddled with bacteria. In addition to airport cabins being veritable Petri dishes of germs from the seat trays to the air nozzles, airport security bins are utterly covered in filth thanks to their passage through hundreds of hands daily. These bins are rarely sanitized, meaning that cold, flu, and other germs deposited by passengers are left for you to pick up and transmit to your mouth, nose, or the handle of your carry-on.

Fortunately, some airports are offering a solution. A new type of tray covered in an antimicrobial substance will be rolled out in more than 30 major U.S. airports this summer.

The bins, provided by Florida-based SecurityPoint Media, have an additive applied during the manufacturing process that will inhibit bacterial growth. The protective coating won't wear or fade over time.

Microban International, a company specializing in antimicrobial products, made the bins. According to the company, their antimicrobial protection works by disrupting the cellular function of the microorganism, making it unable to reproduce. As a result, surfaces tend to harbor less of a bacterial load than surfaces not treated with the solution.

While helpful, Microban is careful to note it's no substitute for regular cleaning and that its technology is not intended to stop the spread of disease-causing germs. In other words, while the bins may be cleaner, they're never going to be sterile.

If you're flying out of major airports in Denver, Nashville, or Tampa, you can expect to see the bins shortly. They'll carry the Microban logo. More airports are due to get shipments by early July.

Bad News: The Best Time of the Day to Drink Coffee Isn’t as Soon as You Wake Up

If you depend on coffee to help get you through the day, you can rest assured that you’re not the world's only caffeine fiend. Far from it. According to a 2018 survey, 64 percent of Americans said they had consumed coffee the previous day—the highest percentage seen since 2012.

While we’re collectively grinding more beans, brewing more pots, and patronizing our local coffee shops with increased frequency, we might not be maximizing the health and energy-boosting benefits of our daily cup of joe. According to Inc., an analysis of 127 scientific studies highlighted the many benefits of drinking coffee, from a longer average life span to a reduced risk for cancer, heart disease, type 2 diabetes, and Parkinson’s disease.

Sounds great, right? The only problem is that the benefits of coffee might be diminished depending on the time of day that you drink it. Essentially, science tells us that it’s best to drink coffee when your body’s cortisol levels are low. That’s because both caffeine and cortisol cause a stress response in your body, and too much stress is bad for your health for obvious reasons. In addition, it might end up making you more tired in the long run.

Cortisol, a stress hormone, is released in accordance with your circadian rhythms. This varies from person to person, but in general, someone who wakes up at 6:30 a.m. would see their cortisol levels peak in different windows, including 8 to 9 a.m., noon to 1 p.m., and 5:30 to 6:30 p.m. Someone who rises at 10 a.m. would experience cortisol spikes roughly three hours later, and ultra-early risers can expect to push this schedule three hours forward.

However, these cortisol levels start to rise as soon as you start moving in the morning, so it isn’t an ideal time to drink coffee. Neither is the afternoon, because doing so could make it more difficult to fall asleep at night. This means that people who wake up at 6:30 a.m. should drink coffee after that first cortisol window closes—roughly between 9:30 a.m. and 11:30 a.m.—if they want to benefit for a little caffeine jolt.

To put it simply: "I would say that mid-morning or early afternoon is probably the best time," certified dietitian-nutritionist Lisa Lisiewski told CNBC. "That's when your cortisol levels are at their lowest and you actually benefit from the stimulant itself."
