I suppose we shouldn’t be surprised if drastic changes outside have an effect within — be they from the vacuum of outer space or extreme cold and heat. Some of the most remarkable changes that your body undergoes when it is put to the test have been discovered by science. Take a look at them, if you’re brave!
Gravity is a given on Earth. Then, when you exit the Earth’s atmosphere, things become a little spooky fast. This invisible force holds the brain in place, and it begins to float around in space as if it were free. It’s just a matter of where it goes.
Breath in the morning isn’t exactly known for its good reputation. On a long flight, though, it seems to be considerably worse. Are there scientific explanations for this phenomenon, or is it just in our heads?
When the weather turns cold, we layer our clothing to keep ourselves warm. It turns out, however, that sweaters have a limit to what they can achieve. Our bodies are at risk if the temperature goes too low. There is no way to avoid hypothermia once it sets in.
Seasickness is a common complaint among cruise passengers on vacation. Everyone knows someone who is always car sick. What if it’s you? It’s possible that many people don’t realise that planes can also cause this form of nausea. Some people are utterly terrified of flying.
Some scientists believe that space radiation exposure could cause gene mutations. The simple act of being in space can alter your DNA. The future generations of your family line would be affected by this.
We can’t avoid it. Travelling by plane is no joke, as anyone who has experienced it can attest. Time zones change as you travel around the world and between the hemispheres. It’s not like your body has a clue.
It’s not uncommon for folks who want to reach high heights without leaving the ground to attempt their best to do it. It’s not uncommon for mountain climbers to encounter extreme weather conditions, and many have survived to tell the tale. During an adventurous trek, what can you expect?
The feeling of being stressed on an aircraft is not uncommon. Is there any other reason we could not be ourselves during a long trip than the challenges of travelling in modern airports?
Flight attendants who work full-time are presumably familiar with this trend. As a result of flying, your taste buds lose their sensitivity to flavor. Your favourite pastime may be ruined for a while by the cabin pressure. Not by chance, tomato juice is very popular in Canada!
The sun doesn’t shine much underwater. As you go deeper into the cave, the light diminishes until it is completely dark. Even midway, it’s not healthy to hang out for too long. Your vitamin D levels will start to suffer, that’s for sure!
For some people, air travel affects the skin. The largest organ in your body doesn’t like to be dehydrated, as we know. Conditions on a plane are just not ideal if your goal is to keep everything plump and supple.
We all know about gravity. But about microgravity? This term refers to the appearance of being weightless in space. It is not zero gravity but simply a very low level of force. Practically, the effect on the body is a puffy face and skinny legs. Yikes!
When you’re flying through the air at a thousand miles per hour, it’s amazing you stay intact at all. Our bodies sure are extraordinary. But still, sometimes, minor side effects happen. Have you ever noticed your feet and ankles are a bit swollen during a flight?
We’ve all had the experience of feeling our ears pop as the plane takes off. Usually, it’s recommended to chew gum to avoid this discomfort. However, when it comes to hearing, why does pressure affect your ears at all, and does it affect some people more than others?
If you’re going to venture into new layers of the atmosphere, you better be ready. When we travel by air, we’re exposed to various rays that we wouldn’t normally be exposed to. Radiation is a threat, even if it’s mild!
We’ve all heard the advice to drink eight glasses of water a day to stay healthy and hydrated. Uncertainty about the advice, however, can prove helpful when flying. During a flight, the body becomes dehydrated to a greater extent than usual.
When they’re grown up, many people wish they could gain a few inches in height. For now, though, unpleasant procedures have had little effect on the short population. NASA has discovered an unexpected solution. If you want to be tall, try a little space travel.
There are different concentrations of oxygen floating around in the sky. In the cabin, you’re protected from the elements while you soar through the clouds. As a result, air pressure differs from that on the ground.
When you leave our enormous blue ball, your muscles also react. Ordinarily, they’re well-tuned to battle gravity and propel us around. That’s when they begin to deteriorate.
Travel disturbs your everyday routine, but perhaps for the better. Whatever the reason for the trip, it’s always wonderful to get away from it all. Enjoy a few tasty meals along the way. Will you be able to eat when the time comes?
When you have to leave, you have to leave. Usually, that’s a foregone conclusion, and it’s probably for the best. People who are away from home, on the other hand, report a change in their restroom habits. What’s the name of it?
There are a lot of obstacles when it comes to bones. A study conducted by NASA discovered that astronauts lose up to 30 per cent of their healthy bone mass while in space. Isn’t that a significant amount of money?
Nobody likes to be bloated and sore after a workout. Blowouts are a combination of both. “Yuck!” you exclaim in disgust. Everyone has to cope with this, whether they like it or not when they’re flying.
Occasionally, people have frozen to death. But along the process, a lot of damage can be done. This happens when exposed skin gets too cold over a long period. Ouch! Nevertheless, pain isn’t the worst-case situation.
25. The sharpness of your vision will diminish when you leave the planet.
Human spaceflight safety is a hot topic. NASA is well aware of many of the dangers after decades of space exploration. When astronauts return to Earth, almost 80 percent of them suffer vision problems. Who or what is to blame?
26. An Increased Risk of Heat Stroke during Summer
Local television may issue alerts when the temperature outside reaches a certain level. As severe as it may sound, the elderly are advised to remain indoors. But even the rest of us face dangers in the world. What is the most extreme reaction, heatstroke?
