7 Terrible Health Tips From Gwyneth Paltrow

Myth No. 4: A vaginal steam with mugwort will balance your female hormone levels.

A Goop guide to spas raved about a "V-Steam." It explained the experience thusly:

You sit on what is essentially a mini-throne, and a combination of infrared and mugwort steam cleanses your uterus, et al. It is an energetic release—not just a steam douche—that balances female hormone levels.

But ob-gyn Dr. Draion Burch told LiveScience that scientific evidence doesn't back this practice up. He even said that it could cause burns or bacterial infections.

Dr. Jen Gunter, another gynecologist, alsoadvised people against the Goop-recommended vaginal steaming, warning that there is a fragile ecosystem within the vagina that can easily be disturbed. She also pointed out that "balancing hormones ... means nothing medical," and that, in any case, "steaming your vagina with wormwood or mugwort will not do anything to hormones because these plants are not hormones."

Finally, Dr. Gunter noted, "the people who push V-steams also need a little anatomy lesson ... steam isn’t going to get into your uterus from your vagina unless you are using an attachment with some kind of pressure and MOST DEFINITELY NEVER EVER DO THAT."

Myth No. 5: Jumping on a trampoline is vastly better for your health than running.

A Goop post about rebounding, which is a fancy term for doing exercise on a trampoline, cited a study that reportedly found the practice was much more beneficial for your heart than running.

"NASA has done research on rebounding and found that it is 68 percent more effective for cardiovascular health and fat burning than running!" the story claimed.

We did some digging and found the study. It's from 1980. The researchers, who were indeed working with NASA, looked at the differences between oxygen uptake and body acceleration when running vs. jumping.

Their goal was to figure out which one might be better for astronauts dealing with the "deconditioning" that happens when they're weightless. (Your average gym rat, meanwhile, is probably not trying to find the best workout for zero gravity, so the results are not entirely relevant.)

The 68% number was actually a measurement of the percentile difference in acceleration (as measured at the back) between running and jumping. It was not a measurement of fat burning.

Furthermore, the study only had eight participants, who were all male. That's too small and homogeneous of a sample to prove much of anything.

The scientists note in their paper that "heart rate and oxygen uptake ranged from resting to nearly maximal levels, regardless of the type of exercise." In other words: get moving, any which way, and you can reap the heart-healthy benefits of exercise.

Myth No. 6: Chemical-based sunscreens are bad for you, and you should only use mineral-based ones.

Goop recommends sticking only to "clean," non-toxic sunscreens. In explaining "Why chemical sunscreens aren't great," Goop says, "Chemical sunscreens employ a potent combination of chemicals like Oxybenzone, Octinoxate (Octylmethoxycinnamate), Homosalate, Octisalate, Octocrylene, and Avobenzone, many of which are hormone and endocrine disruptors."

Scared yet? In fact, clinical studies have found that these ingredients are not harmful to human health.

In a 2011 study on "sunscreen controversies," a team of doctors from Memorial Sloan-Kettering did a thorough review of previous research and found that the only data showing these ingredients were questionable came from animal studies, usually with extremely high doses — not studies in humans, or with doses typically used in humans.

"None of the data published to date conclusively demonstrate adverse effects on the health of humans from the use of sunscreens," the authors concluded. The study noted in particular that oxybenzone hasn't shown hormone disruption in humans.

A follow-up study from 2014 came to the same conclusion: sunscreen ingredients aren't harmful to humans, and applying sunblock to prevent skin cancer is extremely important. You don't need "clean" sunscreens to get these benefits.

Myth No. 7: Colon cleansing is a necessary way to remove toxins from your body.

Colon cleansing is another practice that Goop swears by, particularly in this post that includes an interview with Dr. Alejandro Junger, who developed the Clean Program cleanse. "A colonic helps with the elimination of the waste that is transiting the colon on its way out," Junger says.

When patients are preparing for colonoscopies, which screen for colon cancer, they "clean out" their colon by following a liquid diet, but there are not health benefits to that — it's just so the doctor can see your colon better.

Colonics as "cleanses" — in which liquid is shot through a tube in the rectum into the colon — aren't necessary and carry serious risks, according to Mayo Clinic physician Dr. Michael Picco.

"Your digestive system and bowel already eliminate waste material and bacteria from your body," he wrote for the Mayo Clinic. "[Proponents] believe that colon cleansing improves health by removing toxins, boosting your energy and enhancing your immune system. However, there's no evidence that colon cleansing produces these effects. And colon cleansing can sometimes be harmful."

The side effects, Picco writes, can include dehydration, infections, vomiting, and even bowel perforations.

As a research article in a journal for family doctors noted: "Colon cleansing has no proven benefits and many adverse effects."
