Human body is a lot of things. It is a mechanical device, a walking chemistry set, a sustainable life form, and an ever-changing biological phenomenon. There are lots of things to know. Do you want to know some of them? Let’s check the following list.
You are approximately one half inch taller when you wake in the morning thanks to excess fluid between within your spinal discs. While you are sleeping, these fluids replenish. During the day your body has to deal with the stress of standing, so the discs become compressed and the fluid seeps out. This results in you losing a small amount of extra height.
Yes, maybe it is hard to believe, but we have about the same number of hairs on our bodies as a chimpanzee. It’s just that our hairs are useless, so fine they are almost invisible. We aren’t sure quite why we lost our protective fur. It has been suggested that it may have been to help early humans sweat more easily, or to make life harder for parasites such as lice and ticks, or even because our ancestors were partly aquatic.
People who can’t begin their days without a cup of coffee, they would have to yell for 8 years, 7 months, and 6 days, and thus produce enough sound energy to heat up one cup of coffee when the energy resources of the world go extinct.
The brain is much more active at night than during the day.
The human heart creates enough pressure when it pumps out of the body to squirt blood 30 feet.
Humans are born with 300 bones in their body, however when a person reaches adulthood they only have 206 bones. This occurs because many of them join together to make a single bone.
Our eyes are very sensitive. They are able to detect just a few photons of light. If you take a look on a very clear night at the constellation of Andromeda, a little fuzzy patch of light is just visible with the naked eye. If you can make out that tiny blob, you are seeing as far as is humanly possible without technology.
Sneezes regularly exceed 100 mph & nerve impulses to and from the brain travel as fast as 170 miles per hour.
Scientists have determined that having guilty feelings may actually damage your immune system Research has indicated that approximately eleven minutes are cut off the life of an average male smoker from each cigarette smoked.
As a part of the digestive process, your stomach secretes hydrochloric acid (HA). HA is a powerful corrosive compound also used to treat various metals. The HA your stomach secretes is also powerful, but mucous lining the stomach wall keeps it within the digestive system. As a result it breaks down the food you consume, but not your own stomach.
