Cold Weather May Cause Illness
- Believe it or not, cold weather has no effect on whether or not someone will get sick. The rhinovirus, cause of the common cold, is just that – a virus. As such, it doesn’t depend on external forces of nature to spread from host to host. However, cold weather forces more people inside and into closer proximity. It’s likely that this increased cohabitation and interaction allows the virus to spread.
Knuckle Crackers Will Suffer from Arthritis
- Avid knuckle crackers are at no more risk to get arthritis than people without the habit. However, those prone to cracking their knuckles do find that they have weaker hand strength. An increased risk of swelling in the hands is also a result of popping your knuckles.
Body Heat Escapes through the Head
- Various studies conducted have shown that, in cold weather, the majority of body heat is lost through the head. What these studies fail to account for is that the participants were dressed in warm clothing except for hats. By this comparison, more heat was lost from the head than from covered parts of the body. The truth is, body heat is lost through any uncovered part of the body.
Hand Dryers in Public Restrooms are Sanitary
- In an attempt to be more sanitary, many public restrooms now have motion-activated hand dryers instead of paper towel dispensers. Unfortunately, these dryers often have massive amounts of bacteria growing inside them. The fans can then blow the collected bacteria up to six feet away from the dryer’s own location. As such, these dryers are just as dirty as the door handles.
Reading in Low Light Ruins Eyesight
- Eyes often adjust themselves according to the light, as experienced when a person steps from a dark room into sunlight. This is also true when reading in dim light. While there is a strain on the eyes, no actual damage occurs. Eyesight returns to normal after a period of rest. This is also true of watching television in the dark or using the computer in the dark.
Humans Use Only 10% of their Brains
- Recent studies and imaging technologies have shown that there is not a single part of the brain that remains completely inactive. Multiple areas react to different stimuli, functions, and situations. While the brain may not always be 100% active at all times, humans simply could not function if only a portion of the brain was used.
Cell Phones Cause Cancer
- Radiation has been linked to the development of cancer. However, humans are exposed to amounts of radiation normally throughout the day. Certain foods, like bananas, even give off radiation. The small amounts of electromagnetic radiation given off by cell phones aren’t enough to damage cells, and the body easily repairs any damage that does occur.
These are just some of the myths you should be aware of in your day-to-day war on unhealthy behaviors. So the next time someone tries to lecture you on the dangers of cell phones and cracking your knuckles, you’ll be the wiser!
