The human body is a complex mechanism capable of doing incredible things. It can predict the weather, shut down certain functions to give us a boost of energy, heal internal damage, and even glow.
Deciphering all of the myths and nutty claims people have about the body can be hard, but this list outlines the wild things that are actually true. Though some may be considered creepy, it is interesting to learn about things you can do that you may not have been aware of. Vote up your choices for the coolest things the body can do.
While Still In The Womb, Fetuses Can Heal Their Mothers' Damaged Organs
Fetal cells can remain in their mothers for years, even decades after the end of a pregnancy. These fetal cells that are left behind are more than just souvenirs from the baby; research shows that they can be used as an aid if the mother suffers an injury, such as a stroke.
Louise McCullough, director of stroke research at the University of Connecticut Health Center, conducted a study with colleagues that found that fetal cells can act like stem cells.
McCullough studied fetal cells in mother mice who had suffered strokes. These cells quickly found the location of the area of the brain where the stroke had occurred, and within 72 hours, the fetal cells were surrounding the area of the clot.Weird but cool?
Your Digestive System Can Shut Down To Give You Extra Energy
Desperate times call for desperate measures, and your digestive system can shut down in times of need to give other systems in your body energy. So, yes, you may be able to feel "super strength" when trying to pull a person out from under a car.
Whenever the sympathetic nervous system alerts your brain of danger, adrenaline is released that can increase respiration, accelerate your heart rate, and relax the muscles of the stomach and intestines to decrease the flow of blood to these organs - which can slow down or even stop digestion.Weird but cool?
Your Brain Keeps You From Using Your Full Strength
For centuries, men and women have used their muscles to allow them to compete in the hardest sporting competitions in some of the most intense locations on earth. Doing this requires the body to go past the point of comfort, but the brain doesn't always allow the body to use its full strength.
According to E. Paul Zehr, a professor of neuroscience and kinesiology at the University of Victoria in British Columbia, Canada:
Our brains are always trying to make sure we don't get pushed too far to where we actually damage something. If you actually used all the possible force or all the possible energy you could to complete exhaustion, you'd wind up getting into a situation where you might die.
The human brain works as a computer, monitoring and programming our muscles through learned thoughts and behaviors. However, elite athletes learn to train their "computers" to go beyond their normal operating limits.Weird but cool?
Joints Can Predict The Weather
Can your joints really predict the weather? Rheumatologists have been trying to answer this question for years, and research shows that your joints most likely can. According to orthopedic surgeon Robert Tait, MD:
When a storm front moves in, the atmospheric pressure drops. Major joints' sensory nerve endings register a relative increase in joint fluid pressure, resulting in increased pain.
A 1997 study published in the International Journal of Biometeorology found that there is a correlation between the pain of arthritis and the different weather variables of temperature, relative humidity, barometric pressure, wind speed, and precipitation.Weird but cool?
