MONDAY, June 26, 2017 (HealthDay News) -- When you purchase a new eye shadow or shampoo, you expect those products will be safe and that they won't cause skin breakouts -- or worse.

But new research found that's not always the case. And, because cosmetics are woefully underregulated in the United States, and there's no solid system in place to catch when personal care products are harmful, it's possible you'll never hear about a problem with a product, the study suggested.

A U.S. Food and Drug Administration complaints database contains only 5,144 adverse events between 2004 and 2016 reported in connection with cosmetics, noted the study's senior author Dr. Steve Xu. He's a dermatologist with Northwestern University's Feinberg School of Medicine in Chicago.

"Here is a $400 billion industry with millions of products and multiple controversies, but we only had about 5,000 adverse events over the course of 12 years," Xu said.

FRIDAY, June 16, 2017 (HealthDay News) -- When it comes to discomfort during , forget that old adage "no pain, no gain." New research suggests that excessive strenuous exercise may lead to gut damage.

"The stress response of prolonged vigorous shuts down gut function," said lead author Ricardo Costa.

"The redistribution of flow away from the gut and towards working muscles creates gut cell injury that may lead to cell death, leaky gut, and systemic immune responses due to intestinal bacteria entering general circulation," Costa added. He's a senior researcher with the department of , dietetics and food at Monash University in Australia.

Researchers observed that the risk of gut injury and impaired function seems to increase along with the intensity and duration of exercise.

The problem is dubbed "exercise-induced gastrointestinal syndrome." The researchers reviewed eight previously done studies that looked at this issue.

MONDAY, June 12, 2017 (HealthDay News) -- Traditional Chinese herbal medications might have a role to play in treating or preventing in the West, a research review suggests.

and remain major killers worldwide, accounting for 17.3 million deaths a year, according to the World Heart Federation. This unrelenting death toll has prompted scientists to look to the ancient East for inspiration.

Investigators in China reviewed 56 rigorously conducted studies that examined use of medications rooted in traditional Chinese medicine for conditions such as , , and narrowing or hardening of the arteries ().

Chinese herbal medications might help prevent or treat these conditions, the researchers noted. For patients who can't tolerate or afford high , the research suggested some herbal alternatives: tiankuijiangya, zhongfujiangya, jiangyabao and jiangya.

At the least, the scientists believe their work suggests a need for additional studies to explore Chinese medicine's use as either an alternative to Western medicine or in combination with it.

MONDAY, June 12, 2017 (HealthDay News) -- Nearly 10 million American adults have a serious , and a similar number have considered during the past year, according to a new government report on the nation's behavioral ills.

The report also said that 15.7 million Americans abuse and 7.7 million abuse illicit drugs.

The nation's growing epidemic was also a focus in the report. The researchers found that 12.5 million people are estimated to have misused prescription painkillers such as (OxyContin, Percocet) or (Vicoprofen).

Despite the growing number of Americans with mental health problems, about a third of those who need help aren't getting it, said researcher Dr. Beth Han. She's from the Center for Behavioral Health Statistics and Quality at the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA).

"These are real increases," Han said. The reasons people aren't getting the help they need are varied.

FRIDAY, June 2, 2017 (HealthDay News) -- For people who battled cancer in childhood, the prospects for a long life without cancer recurrence or chronic illness are better than ever, a new study finds.

That's largely due to changes in protocols that have meant less toxicity to children and less chance for long-term side effects, researchers said.

This is the first "comprehensive" study on the issue, said study author Dr. Todd Gibson, who's with the cancer control department at St. Jude Children's Research Hospital in Memphis, Tenn.

As the researchers explained, more children are surviving , but the and radiation they receive as treatment can raise their risk for adult illness years later.

So, cancer specialists have worked hard over time to modify treatments to maximize benefits but minimize long-term risks.

And it seems to have paid off.

In the new study, Gibson's team tracked health outcomes for almost 24,000 U.S.

Comic powerhouse Kevin Hart is big. Really, really big.

This is no accident. When Hart takes on a challenge, he goes full throttle. With mottos like "The sky's the limit" and "No days off," no one should be surprised he's skyrocketed into the stratosphere.

"Always putting forth the best effort possible is what my life is about," says Hart, 37. "I'm pure proof that quitting is not a choice. This is my lifestyle -- always wanting to improve, always wanting to do more and get better."

Hart employs this philosophy in just about every corner of his life, including his health. His regimen is serious business. Whether it's , boxing, , core work, or , he's all in -- typically 7 days a week, with only 1 to 2 days off per month.

When he's shooting a movie -- like Captain Underpants: The First Epic Movie, out this month, or Untouchable, which he recently filmed with actor Bryan Cranston -- he doesn't let up.
