There are many things and myths that people have been believing for a few decades, like for instance cracking your knuckles may lead to arthritis among many others. Here is the factual proof of each myth and how it’s not what you think it is.
1. Do not crack or pop your knuckles; it might give you arthritis.
Truth: No study has found any link between popping your muscles and arthritis. The sound that comes when you crack your fingers is not from the bones. The sound is made when tiny gas bubbles inside the joints burst or when the ligaments stretch.
2. Depression is synonymous with sadness.
Truth: It is a common belief that depression occurs due to sadness and that a sad person is necessarily depressed. However, a research conducted by the National Institute of Mental Health (NIMH) reveals that those suffering from depression might feel sad, but most of the time, they do not feel any emotion at all. Rather than sadness, a better emotion to describe how a depressed person feels would be apathy or emptiness.
3. Swallowing a chewing gum may cause it to get stuck on your stomach lining for years.
Truth: Doctor David Milov from Children’s Clinic in Florida has informed the Scientific American Journal that capsule endoscopy procedures and colonoscopies have proved that nothing like this happens. In fact, a gum may leave its traces in your digestive tract for a maximum of one week.
4. Tomatoes are vegetables.
Truth: A tomato is not a vegetable, it’s a fruit. Tomatoes were classified as vegetables under the Tarrif Act of 1883 so that taxes could be collected for their production.
5. Dogs sweat via their tongue.
Truth: Dogs are blessed with sweat glands and they are mostly located on their footpads. Putting their tongue out while panting helps dogs in controlling their breathing mechanism.
6. You should drink at least 8 glasses of water every day.
Truth: Yes, drinking water is healthy, but putting a number on the amount of water intake is not. In fact, nobody knows how this number and myth originated. Drink water when you are thirsty. If you are living in a dry area, your body will get dehydrated quickly and you’ll feel the need to drink more water, don’t force it on your body unnecessarily.
7. Carrots improve your vision.
Truth: This myth was generated in WWII when the British army spread the rumor that their soldiers had amazing night vision due to their intake of carrots. However, the real reason behind improved vision of its soldiers was the radar in their aircraft, which made it easier to detect enemy locations. No doubt it is healthy to eat carrots since they are a rich source of potassium and dietary fiber, but they do not improve your vision.
8. Eating chocolate gives you acne.
Truth: If you have acne on your skin, you should blame acne vulgaris, a bacterial strain that fills your pores when they get exposed to oil and dirt and not chocolate. Foods that are rich in sugar and oil can aggravate blemishes caused by acne, so controlling their intake is essential. However, chocolate is not the reason why people get acne.
9. The Great Wall of China is the only structure on earth that is visible from space.
Truth: Firstly, define space for us. Is it 1,000 miles away or 15,000 miles? Well, International Space Stations have said that they cannot see the Great Wall from space. Maybe you’d like to take a trip to space and check?
