The strong scent of onions may act as a deterrent for mosquitoes and other pests. If you’re looking for a chemical-free way to keep bugs away, placing a sliced onion near windows or your sleeping area could be worth a try.

4. Easier Breathing at Night

Some believe that the antimicrobial properties of onions might help clear the air, making it easier to breathe—especially if you suffer from allergies or mild congestion. While not a substitute for medical treatment, it’s a simple hack that might offer some relief.

How to Test It Out

Want to see if it works for you? Here’s how:

• Cut an onion into halves or quarters.
• Place it in a small bowl near your bed or on a nightstand.
• Leave it overnight and see if you notice any difference.
• Discard it in the morning—don’t reuse it, as bacteria can grow on the exposed surface.

Important Precautions

• Keep away from pets – Onions are toxic to cats and dogs.
• Ensure good ventilation – The smell can get strong if the room is too closed off.
• Don’t expect miracles – While some people find benefits, results vary.

The Verdict: Does It Really Work?

There’s limited scientific evidence, but onions do have properties that could help with air purification, insect repellent, and respiratory comfort. Since it’s a harmless and cost-free experiment, why not give it a try? You might be surprised by the results!
