Gravity ensures that the blood in our body maintains an optimum blood pressure level. While standing, the blood pressure in our feet is as high as 200 mm Hg (millimeters of mercury). In the brain however, the pressure is only 60 to 80 mmHg.
Also to know is, how does Earth’s gravity affect objects near Earth?
Near the Earth’s surface
A gravity force acts on an object regardless of whether it is moving or not moving. In everyday situations, the size of the gravity force on something does not change significantly as it rises above the Earth. (An object needs to go much higher than a jumbo jet for major differences to occur.
Similarly, how does the Earth’s gravity affect you everyday?
Gravity on Earth
Gravity is very important to us. We could not live on Earth without it. The sun’s gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun’s light and warmth. It holds down our atmosphere and the air we need to breathe.
How would stronger gravity affect humans?
If its gravity is too strong our blood will be pulled down into our legs, our bones might break, and we could even be pinned helplessly to the ground. Finding the gravitational limit of the human body is something that’s better done before we land on a massive new planet.
What are 5 facts about gravity?

What happens if there is no gravity?
Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence.
