Health24.com | Study warns of further damage to the body from deep space travel
Deep space travel has been shown to harm astronauts’ eyes, muscles, hearts and immune systems. Now, new animal research suggests that venturing beyond Earth’s protective atmosphere could also damage their gastrointestinal tracts.
“We have documented the effects of deep space radiation on some vital organs, but we believe that similar damage responses may occur in many organs,” explained senior investigator Dr Kamal Datta.
He is a project leader of the NASA Specialized Center of Research (NSCOR) at Georgetown University Medical Center in Washington, D.C.
“It is important to understand these effects in advance so we can do everything we can to protect our future space travelers,” Datta said in a Georgetown news release.
In the study, Datta’s team exposed mice to a low dose of iron radiation at the NASA Space Radiation Laboratory (NSRL) in Brookhaven National Laboratory in New York. The mice received a very low dose over the equivalent of a months-long stay in deep space. The rodents were then examined at Georgetown.
Another group of mice was exposed to gamma rays, which are comparable to X-rays on Earth. These two groups of mice were then compared to a third group that had no radiation exposure.
From observing the iron radiation mice, the researchers said they found the constant bombardment by galactic cosmic radiation in deep space could cause significant damage to gastrointestinal tissue, such as the stomach and intestines. This damage, they warned, could lead to long-term health issues and increase the risk for cancers of the stomach and colon.
“Heavy ions such as iron and silicon are damaging because of their greater mass compared to no-mass photons such as X-rays and gamma rays prevalent on Earth,” Datta said.
The researchers found that these intestinal cells did not absorb enough nutrients and they formed cancerous polyps. The researchers also found evidence that iron radiation triggered DNA damage that increased the number of cells that were incapable of normal cell division.
“They generate oxidative stress and inflammatory molecules that induce more damage. This greatly affected migration of cells that are needed to replace the intestinal lining, which slowed down GI functioning,” said Datta, who is also a member of Georgetown Lombardi Comprehensive Cancer Center.
The effects of the iron radiation appeared to be permanent, the study showed, though research on animals frequently doesn’t lead to the same results in humans.
The findings were published October 1 in the Proceedings of the National Academy of Sciences.
“With the current shielding technology, it is difficult to protect astronauts from the adverse effects of heavy ion radiation. Although there may be a way to use medicines to counter these effects, no such agent has been developed yet,” Datta said.
“While short trips, like the times astronauts traveled to the moon, may not expose them to this level of damage, the real concern is lasting injury from a long trip such as [to] Mars or other deep space missions, which would be much longer,” he added.

I Did 100 Push-Ups Every Day for Over a Year
It all started as a CrossFit challenge at the box I used to frequent near my home in Burlington, VT. For the month of November, our coaches asked members to see how many push-ups they could do each day. Maybe it was 25, or 50, or more. Hmm, I thought, an ersatz CrossFitter who really just wanted to run and have fun instead of obsessing about performing a perfect deadlift. I wasn's so great at snatches and bungled my burpees, but a push-up? Well, that I could do.
So I signed up to do 100 a day—right before a spa getaway with my mother in Arizona. In between massages and meditation with my mom, I somehow managed to sneak in a set of 10 here, a set of 10 there, and went to sleep even more soundly in the Tuscon desert knowing I'd hit the 100 mark. (Related: The 30-Day Push-Up Challenge for Seriously Sculpted Arms)
And so it began, these sets of 10 that became the metronome of my life, not only as I returned to my own motherly duties in the Green Mountains for the remainder of the month, but also beyond that, into December, and then January. Some pretty amazing things were happening to my body, and to my mind. My arms were more toned than ever, I had a tight core, and I felt that I stood taller than before. What's more, I was increasingly confident about my own capabilities as an athlete. With the 100-mark under my belt for the day, I could move on to tapping away at my keyboard, texting friends, or enjoying dinner with my husband and two kids knowing that I'd put in an honest day's work. On the floor.
So that was the funny part. The floor. The stuff that I saw, and that I did, while a few inches off the ground. In the pre-dawn hours of a cold February day, I'd find myself in the living room, picking up long-lost Legos from the tufts of our orange shag carpet in between sets. In the kitchen on a warm summer morning, I'd be eye-to-eye with a slug, or a millipede, or a moldy Cheerio. I'd have eureka moments, where I'd suddenly think of the ideal Christmas gift for my nephew or the punniest headline for a story. I'd empty one level of the dishwasher, hit the ground for 10, and then have the coffee going while banging out the next 10 or 20.
Did it suck? Oh boy, yes. There were many mornings when, tired from tossing and turning about daily stresses, I swore I'd never do another damn push-up. But after eking out five, I'd feel my mood improve—and the physical changes in my body were serious motivation. (Just beware of these 7 Push-Up Mistakes You're Probably Making.)
After more than a year of my 100 daily push-ups, I quit CrossFit—but kept up with the challenge in my local gym, learning to be impervious to the rolled eyes or the questioning looks as I added my own reps during a BodyPump class. When I entered a GoRuck adventure race that spring, I was able to move on to the next stage of the event thanks to my push-up proficiency, and the same skill also got me through a 36-hour venture into the wilderness in California that fall.
I was hooked, and I was having fun—and making friends. Strangers at the gym had a reason to start up a conversation with me, getting a laugh or two when I revealed my mission. I saw the world in a different way. When I went on work trips or on vacation, I found new, inventive places to practice my push-ups. London, New York, California wine country, Denver, Montreal—they all saw a certain blond ponytail bobbing up and down in the push-up position.
One day last spring, I stopped, as I decided to unplug from most everything (screens, work, working out) for a month to give my mind and body a break from the hamster wheel of life. I felt free, and then I felt a bit flabby as my arms lost some of their muscle tone and my core grew curvier. What would I do now, commit to the 100-a-day again, or give it up entirely?
The answer came somewhere in the middle. I still do push-ups. Most days. Not every day, and not always 100. But every time I find myself face to face with a floor, I smile, and start counting.
