Gravity plays a big role in the body’s ability to restore bone tissue, bone and cell function. This leads to a significant loss of bone mass, at a minimum.
Space travel takes its toll on the human body, and life in anti-gravity conditions, especially on Mars, is hard on the bones. From isolation to radiation to crushing intracranial pressure, the imbalance is proving quite severe, Grunge writes.
Although landing on Mars is something of an amazing feat, scientists say, but actually living there is almost impossible. Living on the Red Planet can cause a heart attack, or at least seriously increase the risk of having one. The University of California San Francisco reports that prolonged exposure to space can actually wear out the cardiovascular system. This is due to the toxic combination of radiation and lack of gravity, which makes it difficult for the circulatory system to function.
According to Dr. Marlene Grenon, low-gravity simulations suggest that living in microgravity can even change how certain genes are expressed in cells, especially genes that conduct electricity in the heart. Changes in these cells can lead to an increased risk of heart arrhythmias.
It is also known that heart rate can change in zero gravity. This is due to the fact that it becomes easier for the heart to pump blood after gravity is removed. That is, astronauts living on Mars are not only more prone to fractures, but also lose bone density at an accelerated rate, leading to premature aging of their skeletal components.
In 2021, a new study found that exposure to space radiation also causes DNA replication errors, another problem that causes astronauts’ bodies to age prematurely. These experiments were conducted in laboratories with low gravity, but we can assume that the effects of radiation on the Red Planet will be even worse. According to experts, Mars has a radiation dose that is 17 times higher than Earth.
Unlike Earth, which is naturally equipped with a magnetosphere to protect against radiation particles, Mars has no natural barrier to provide such assistance. Living in zero gravity can result in pretty severe sunburns for Martian soil dwellers.
In addition, returning to gravity can also be hard on the body.
“One of the biggest problems since the beginning of the manned space program is that the astronauts passed out when they came down to Earth. The longer they are in zero gravity in space, the greater the risk that appears,” explained the professor of the Department of Internal Affairs, MD Benjamin Levin.
This is because the sudden reversal of gravity results in a dizzying drop in blood pressure, which is sometimes combined with a jump in heart rate.
Recall that earlier scientists created a new map of Mars, which showed which surfaces of the Red Planet were covered with water.
