When astronauts return to Earth from space, they usually experience many physical problems as a result of prolonged weightlessness. One of the low-ended health complications is known as “baby feet”. This effect, which is likely to be in NASA astronaut Sunita Williams and Buch Wilmor, may be uncomfortable and challenging when they return to Earth. But what is this situation, and why does it happen?
NASA, SpaceX canceled the return of astronauts; New date is here
NASA and SpaceX on Wednesday launched the effort of launching the agency’s crew -10 mission to the International Space Station, as for the Falcan 9 Rocket launched Complex 39A at NASA’s Kennedy Space Center in Florida, a “Hydraulic System with a” Hydraulic System Issue with a “Hydraulic System Issue with a” Hydraulic System Issu NASA.
The launch coverage will start at NASA+at 3:25 pm (local time). And Docking is targeted at 11:30 pm (local time) on Friday.
What is this strange space syndrome?
The word “baby feet” describes the hypersensitivity and softness of the soles of astronauts after spending an extended period in microgravity. In space, astronauts do not move or do not put pressure on their feet the way they do on earth. Instead, they float and use their hands, often hold bars and handles inside the spacecraft. As a result, their feet, especially the soles, undergo significant changes.
Thick skin at the bottom of the feet, which develops naturally by walking and standing, gradually becomes soft due to lack of pressure and friction.
The main cause of ‘baby feet’ among astronauts is the lack of weight-bearing exercise in space. On the ground, the soles of our feet are constantly pressurized by standing, walking and wearing shoes. It causes the development of a thick, hard layer of the skin, which is referred to as callus.
When astronauts return to Earth, they may feel pain, tingling or discomfort by placing their feet on the ground. They can compare the feeling of walking barefoot for a few months after walking in a soft slippers, or after walking on a soft ground. Long -term space travel will change blood flow and sensitivity to the veins, once again contributing to the feeling of discomfort while touching the ground.
How do astronauts recover from the child’s feet?
Rehabilitation is an important component of the return of an astronaut in regular life on Earth. NASA and other space agencies have set up programs that help astronauts to reverse the effects of microgravity. Important steps are:
Astronauts need to re-compile their legs for pressure and friction by walking on soft surfaces before changing on hard surfaces slowly. It tightens the skin once again and reduces discomfort.
Specific exercises are designed to restore muscle strength in the legs and legs. Resistance training and stretching restored mobility and endurance.
Astronauts are given balance training to restore coordination and stability. This may include standing on one leg, walking heel-to-foot finger and using the balance board.
Proper hydration and a calcium -rich diets help restore bone and muscle health, help in overall recovery.
Other effects of space travel on the feet
In addition to ‘Baby Fat’, astronauts experience many other physical changes that can affect their lower limbs:
In microgravity, the body’s fluids move upwards towards the head, leading to a puffy face and thin legs, a condition often called “chicken leg syndrome”. When returning to Earth, the body re -adjusted, and the legs may feel swollen and normal blood circulation starts again.
Since walking and running is unnecessary in space, astronauts experience muscle loss, especially in their feet and legs. Even though they follow strict exercises in the classroom, their leg muscles can still be weak, making it challenging to walk properly after landing.
The inner ear, responsible for maintaining balance, also adjusts weightlessness. While returning to Earth, astronauts often have trouble with dizziness, impaired coordination, and standing up straight because their body has to study for gravity.
Prolonged contact for microgravity results in bone loss, especially in weight -carrying bones such as legs and legs. It is a risk factor for fracture and rehabilitation after the mission.
