This effect can be countered by spending more time away from people outside when it is cold, but no, the cold air of winter does not kill germs.
If germs die of cold it is either because they dried out or because the water inside the bacteria froze.
Some germs can survive either though.
Do germs die in cold weather?
Research suggests that these viruses may survive and reproduce more effectively at colder temperatures, making it easier for them to spread and infect more people. Cold weather may also reduce the immune response and make it harder for the body to fight off germs.
Does cold kill bacteria?
Freezing foods renders bacteria inactive but doesn’t actually kill anything. That means if your food went into the freezer contaminated, once thawed it will still harbor the same harmful bacteria. Cooking it to the recommended temperature is the only way to ensure that your food is safe.
What temperature will kill bacteria?

Can you get sick from cold weather and wet hair?

Vinegar can be used as a safer bleach alternative for some applications, like cleaning. It is also biodegradable. However, vinegar is not a registered disinfectant and does not kill dangerous bacteria like staphylococcus. Hydrogen peroxide has antimicrobial ingredients and can be an effective household cleaner.
Can Ice carry germs?
Ice does not inherently carry bacteria if the original source of water was clean.
Can you freeze food twice?
Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods. Freeze leftovers within 3-4 days.
Does putting shoes in freezer kill smell?
Freeze your shoes. Put your smelly shoes in a plastic bag, and then put them in the freezer over the course of a night. The idea is that freezing the shoes kills the odor-producing bacteria. If the freezer trick does not work, put in a healthy dose of baking soda and let the powder absorb the odor overnight.
