Astronaut gets HIGHER in space: understand

Astronaut gets HIGHER in space: understand

Many small people would love to add a few centimeters to their height and was just what Japanese astronaut Norishige Kanai did: he grew two centimeters after spending three weeks on the International Space Station. But this is not the first time this happens to people who go to space and usually the growth registered is two to five centimeters.

Can you imagine why this happens? Yes, it has to do with gravity. Or rather, with her absence. "The explanation would be that, without gravity, the spine could expand, it is the gravitational action. The person can have this growth, there is a limit according to the size of the patient, and when he returns, gravity becomes act again and it resumes the same height as before, "says orthopedist Bruno Rabello.

This can also happen to us here on Earth. "If we measure ourselves in the morning and afternoon, we can see that we will be lower by the end of the afternoon.This is because when we sleep we do not feel gravity affect us from head to toe as we lie.With lack of gravity pressing the column, these vertebral discs, which are between the vertebrae, rehydrate and expand at night.The older we are, the less hydration in the discs, which results in arthrosis, etc. ", completes the orthopaedist Alberto Tesconi of BP - The Beneficência Portuguesa de São Paulo

Muscular and bone loss

Despite the extra centimeters, life in space does not provide good conditions for the body. "The loss of bone mass they have is enormous, because there is no gravitational action, so they do not stress the muscles and end up losing muscle tone. They need to do a nutritional recovery, not to lose as much bone and muscle mass," explains Rabello .

The effect is similar to that of a very sedentary person, who ends up developing osteoporosis by disuse. "In the muscular part there is the nutritional work with protein replacement, hormone replacement, testosterone, so as not to have too much muscular loss" , completes Bruno. However, the specialist believes that these challenges in space can bring good indications of solutions to be used in patients here on Earth.
