Have you heard of these common beliefs? Some people call them "old wives’ tales" because they are believed to have been passed down by women a long, long time ago. Some of these‘theories’are true. Some are not. Can you tell which ones are real?
1. An apple a day keeps the doctor away
True. Apples have nutrients that make you stronger. Researchers have found that they may also protect you from cancer! Scientists found that apples could prevent breast cancer in primates and they believe that the same might be true for humans too.
2. Drinking warm milk makes you sleepy
True. When you were a baby, you often fell asleep after a bottle of milk. Drinking warm milk triggers a subconscious memory of this without you noticing. This nice feeling makes you feel calm and sleepy.
3. Carrots are good for the eyes
True. Carrots do not make you see better in the dark. They do not improve your vision either. But they can reduce the risk of developing macular degeneration, an illness which will lead to blindness. This usually happens in older people, so start eating your carrots now to prevent developing it!
4. You will catch a cold if you go outside with wet hair
False. Feeling chilly does not cause a cold. Viruses cause colds. Some researchers conducted an experiment about it. They asked two groups of people to stay in two rooms with viruses that cause the common cold. One room was chilly. Another room was warm. Guess what happened? Both groups caught the cold!
