(CNN) -- Feed a cold, starve a fever. Eat a lot of carrots for good vision. Are these 'old wives' tales' or are they legit?
Today is April Fool's Day and so we decided to have a little fun.
We've all heard at least a few old wives' tales- pieces of advice that have been passed down from previous generations.
Here is a break down some popular claims to see if they are 'old wives' tales or not.
Cracking your knuckles causes arthritis. There are no studies to confirm that. When you crack your knuckles, it's actually gas expanding that causes the noise.
Going outside with wet hair will make you sick. Not necessarily. The decrease in body temperature could potentially make you more susceptible to certain viruses, however, just going out with wet hair does not always mean you're going to catch a cold.
You should feed a cold and starve a fever. The key to any illness is making sure you're staying hydrated. Eating is not necessary, but definitely staying hydrated is important.
Ok. How about one that's at least partially true?
Eating a lot of carrots can help your vision. Eating an excess of them is not going to improve your vision. However, it will provide you with Vitamin A that’s needed for vision, but eating them in excess is not going to give you x-ray vision or anything spectacular like that.
One thing for certain? Getting a good amount of veggies is always a good thing.
