According to (CNN) researchers, the rigors and challenges of spaceflight for cancer patients used during chemotherapy and other treatments are remarkably similar.

For that reason, researchers suggest that the countermeasures program used before and after astronauts by astronauts to maintain their health could be developed for cancer patients and allow them to recover after treatment Can be applied to help.

The description was published in the journal Cell on Thursday in a commentary written by researchers at Memorial Sloan Kettering Cancer Center and NASA. The program was supported by the National Cancer Institute.

Jessica Scott, senior author, and an exercise physiology researcher said, “When we looked at the similarity between astronauts and cancer patients, massive reductions in muscle were seen during treatment. Memorial Sloan Kettering At the Cancer Center’s Exercise Oncology Service.”

Astronaut Exercise programs could help cancer patients: Finds Researchers

“Astronauts may find something called Space Fog, where they get a meditation center Above to the difficulty or a little forgetful. This is very similar to the experience of some cancer patients, known as the chemo brain. ”

But astronauts and cancer patients are advised in a completely different way from each other, despite similar issues. The authors of the commentary looked at the Countermeasures program created by NASA to see how it could apply to cancer patients.

For 58 years, NASA has been sending astronauts to space, with flights ranging from 15 minutes in the 1961 period to about one year on the International Space Station for current astronauts.

The search for countermeasures quickly began to help humans stay stable and healthy in space. They did not know what the effect of zero gravity could have on the body or specific organs. And they were primarily concerned with heart injury, so according to the comment, several assessments were made to monitor that activity during and after the flight.

NASA’s concerns were valid. The authors wrote, Apollo astronaut James Irwin had undetermined coronary heart disease and 21 months after returning to Earth, he suffered an acute infarction.

Initially, astronauts of Project Mercury, announced in 1959, had to run every day for a month before their spaceflight. Gemini astronauts exercised using bungee cords before their missions and during spaceflight. Until the Space Station mission began in 2001, NASA astronauts performed a combination of aerobic exercise and strength training during their 91- to the 215-day mission.

Now, in the months prior to launch, astronauts work with experts to create a power, position and rehab program to create a baseline to fly. They continue the program using equipment at the station. When they return, the astronauts are monitored as they exercise to ensure that their fitness returns to the baseline level established before the spacecraft.

After more than 50 years of manned spacecraft, researchers discovered some of the risks to the human body from being in zero gravity. Astronauts have to deal with a stressful environment, noise, isolation, interrupted circadian rhythms, radiation exposure and a peak fluid shift that occurs when opposed to standing on solid ground.

Over time, astronauts living at the station for six months or longer may experience weakening and loss of bone and muscle atrophy. According to NASA’s Human Research Program, astronauts experience a decrease in blood volume, a weakened immune system and a drop in heart rate because floating takes a little hard work and the heart does not have to work hard to pump blood.
