Whether passed down from generation to generation or circulated over the internet and social media, medical myths like drinking at least eight cups of water a day or using salt water to bathe during Ebola breakout period, are just myths.It’s challenging enough trying to eat right and keep fit, all while staying on top of your responsibilities at work and at home. Then you click on a health article that was just shared by that guy you met that one time at your friend’s Halloween party and, boom, yet another thing to worry about. Fortunately, this is not one of those articles. Let’s dispel three extremely common (but totally false) health myths you’ve spent your entire life believing.
MYTH 1: A Woman Cannot Get Pregnant During Her Period
In a typical 28-day cycle, a woman ovulates on day 14 (on average), a process that lasts about 12 to 48 hours. But that doesn’t mean conception can’t occur outside that window. Furthermore, If you got Intimate during your period without protection, sperm can live for three to five days in the female genital tract. So even if ovulation happens after bleeding stops, if the sperm are still present, conception can occur.
MYTH 2: Cold air causes colds
You may have heard this one from your mother: "Don't go outside with wet hair or you'll catch cold!" With all due respect to Mom, that isn't how colds are spread. If you go outside in cold weather, with or without wet clothes or hair, you stand no greater risk of catching cold. Colds come from viruses, and viruses can be spread regardless of the weather.
MYTH 3: Supplements always make you healthier
Vitamin supplements may be not only ineffectual but even dangerous, studies have shown. For example, a study published in 2016 showed that some older women who take calcium supplements may face an increased risk of dementia. And in a huge review of 20 years of supplement research published in 2015, researchers found that taking high doses of vitamins may be linked with an increased risk of cancer.
