- Gravity affects many parts of your body as you age. It compresses the spine, contributes to poor blood circulation and can decrease your flexibility. The gravitational pull also affects your organs, causing them to shift downward, away from their proper position. Gravity is often blamed for the way excess weight accumulates around the midsection.

Jun 15, 2017 · Gravity and the Human Body. Our bodies function necessarily under the presence of gravity; how blood pumps, a sense of balance and bone growth are all due to life in a world where gravity is an inescapable reality.
May 8, 2021 · The study showed that Earth-bound physiology and spaceflight physiology differ, and it has been apparent that microgravity affects the magnitude of the human physiology and not only isolated physiological systems.

It wasn’t until explorers traveled to space that any earthly creature had spent time in a microgravity environment. Scientists observed that returning astronauts had grown taller and had substantially reduced bone and muscle mass. Intrigued, researchers started comparing blood and tissue samples from animals and astronauts before and after space tr...
Along with the force of gravity, our cells are also subjected to additional forces, including tension and shear stresses, as conditions change within our bodies. Our cells need ways to sense these forces. One of the widely accepted mechanisms is through what are called mechano-sensitive ion channels. These channels are pores on the cell membrane th...
Over the past three decades, researchers have carefully teased out how particular kinds of cells and body systems are affected by microgravity. 1. Brain: Since the 1980s, scientists have observed that the absence of gravity leads to enhanced blood retention in the upper body, and so increased pressure in the brain. Recent research suggests this hei...
NASA and other space agencies are investing to support strategies that will prepare humans for longer-distance space travel. Figuring out how to withstand microgravity is a big part of that. The current best method to overcome the absence of gravity is to increase load on the cells in another way – via exercise. Astronauts typically spend at least ...

Discover how gravity impacts brain function and cognition in this insightful article from BBC Science Focus Magazine.
Gravity and the Human Body. Background Information: As the human race sets their goals on space travel and on exploring other planets, we have to look at how long exposure to free-fall and microgravity affects the body. Space medicine is a new field that is growing fast as the International Space Station becomes a reality.
