7 Health Benefits of a Cold Shower

Most people enjoy taking a hot shower, but finishing off with cold shower has several health benefits.

Benefits of Cold Water Showers

While doctors may no longer instruct their patients to take a cold bath and call them in the morning, a shot of cold water can still impart real health benefits:

Improves circulation. Good blood circulation is vital for overall cardiovascular health. Healthy blood circulation also speeds up recovery time from strenuous exercises and work. Alternating between hot and cold water while you shower is an easy way to improve your circulation. Cold water causes your blood to move to your organs to keep them warm. Warm water reverses the effect by causing the blood to move towards the surface of the skin. Cold shower proponents argue that stimulating the circulatory system in this way keeps them healthier and younger looking than their hot water-loving counterparts. Read more

Can Sunscreens Actually Cause Cancer?

If you think that slathering on sunscreen is protecting you against skin cancer, you may want to think again. Many sunscreens may be accelerating cancer.

Almost half of the 500 most popular sunscreen products may actually increase the speed at which malignant cells develop and spread skin cancer because they contain vitamin A or its derivatives, according to an evaluation of those products released today.

AOL News also has learned through documents and interviews that the Food and Drug Administration has known of the potential danger for as long as a decade without alerting the public, which the FDA denies. Read more

Think Faster, Exercise Harder, Live Longer

Men's Health tells you everything you need to know about the many health benefits of caffeine.

By now you'd think scientists could close the book on caffeine and move on to other mysteries, like why anyone would ever order a chai latte. After all, coffee and related beverages have been revving people up since, oh, the 15th century. And in the past 60 years, researchers have conducted more than 21,000 studies on our favorite stimulant. That's an average of one new study a day through all of those decades. (Those nutrition scientists may have gotten into their own stash.)

If we don't know caffeine by now, you may well ask, when will we know it? And do I have time for a fix while I'm waiting?

Make it a venti, and sit down. We'll explain a few things. First off, caffeine is a complex compound. And it's made even more so by America's preferred delivery method, coffee. For instance, caffeine raises blood pressure, but habitual coffee drinkers are half as likely to die of heart failure as those who don't fill their mug daily. And while caffeine spikes blood sugar, a java habit may help you dodge diabetes.

Confused? Then use this primer to learn how to consume caffeine to your advantage--at work, in the gym, and for overall health. Read more

Best Foods to Promote Hair Growth

Your diet is reflected in your hair, so Fleur Hupston suggests which food to eat - and which to avoid - to promote hair growth.

Shiny, healthy and abundant hair is of great value to people. When hair starts thinning or falling out, it can cause panic, distress and anxiety for the individuals concerned. Many cures are put forward by the hair industry, yet dietary deficiencies, poor dietary choices, toxic hair care products and poor hair care are often the cause. Stress and chronic disorders can also cause hair loss. There is no overnight cure for hair that has been damaged by a bad diet. Encourage hair growth with natural "hair foods". Read more

Living Prehistorically in the Modern Age

Andrea Shea explains how to live prehistorically in the modern age. She apparently doesn't know that Neanderthals and modern humans were a different species, but not everyone watches the History Channel, I guess. Otherwise, it's a good introduction to the Paleolithic lifestyle

The word “Paleolithic” might evoke images from the 1980s film “Quest for Fire” — or, more recently, the scruffy cavemen in those Geico commercials. But Nate Rosenberg says going back in time to eat like a Neanderthal doesn’t make him one.

“It’s obviously not a reenactment of Paleolithic life,” Rosenberg says.

The 27-year-old foraged through his contemporary kitchen in the cute Somerville apartment he shares with his Paleo partner Michal Naisteter.

“We eat modern foods,” he says. “In the Paleolithic era they did not have ground beef or, you know, dried oregano from Whole Foods and stuff life that, which we benefit from. But we try keep in mind our evolutionary history.”

Added Naisteter: “I eat fish, I eat eggs, I eat vegetables and I eat berries and nuts.”

Naisteter and Rosenberg are part of an international fitness and nutrition movement known as “ancestral health.” Read more
