Spooky Myths vs. Medical Facts: A Halloween Health (and Fact) Check

Halloween is the perfect time for costumes, candy, and a little bit of spooky fun. But it’s also a season filled with myths that can send shivers down the spine—especially when it comes to health. At Perham Health, we want to separate the tricks from the treats and make sure you and your family stay safe and informed this Halloween.

Myth #1: Eating too much sugar makes kids “hyper”

The spooky tale: Parents have long believed that candy-fueled kids bounce off the walls with sugar-induced energy.

The fact: Scientific studies show sugar itself doesn’t directly cause hyperactivity. What you’re probably noticing is the excitement of costumes, parties, and trick-or-treating! Still, consuming too much sugar can cause stomachaches, dental issues, and long-term health concerns—so moderation (and a good toothbrush) remains the best policy.

Myth #2: Cold weather causes colds

The spooky tale: Step outside on a chilly October night without a jacket, and you’ll “catch a cold.”

The fact: Colds are caused by viruses, not temperature. What is true: people tend to spend more time indoors in close contact during colder months, which makes it easier for germs to spread. So bundle up for comfort, but remember—it’s handwashing, masking, and the flu vaccine, not your winter coat, that keeps the sniffles away.

Myth #3: Swallowing Halloween gum will stay in your stomach for seven years

The spooky tale: That piece of bubble gum you accidentally swallowed is now lodged in your body until the next decade.

The fact: Gum doesn’t break down in your stomach, but your digestive system still moves it along—just like other food. It usually passes within a few days. Still, swallowing large amounts of gum (especially with candy wrappers or other non-food items) can cause blockages, so it’s best to spit it out properly.

Myth #4: The flu vaccine can give you the flu

The spooky tale: Getting your annual flu shot means you’ll feel sick or “catch” the flu from the vaccine itself.

The fact: The flu vaccine cannot give you the flu—it’s made from inactivated virus or specific proteins that train your immune system to recognize and fight the real thing. Some people may experience mild side effects, like a sore arm or low-grade fever, but these are signs your body is building protection. The actual scare is skipping the shot: influenza can cause severe illness, hospitalizations, and even death, especially for vulnerable populations. Protect yourself and your family—don’t fear the flu shot!

Myth #5: Blood donations leave you weak or “drained”

The spooky tale: Give a pint, and you’ll be pale and faint like a vampire victim.

The fact: Donating blood is safe and quick—your body replaces the fluid within 24 hours and the red blood cells within a few weeks. Most people feel fine afterward, especially if they stay hydrated and eat a healthy snack. And every donation can save up to three lives—a true Halloween hero move.

Halloween is full of tricks, but your health doesn’t have to be one of them. Remember to brush those teeth, wash those hands, get your flu shot, and keep safety in mind while celebrating. And if an accident or illness does put a chill in your holiday, our team at Perham Health is here to provide care you can trust—no spooky surprises.
