It may sound like something out of an old folktale, but placing a clove of garlic under your pillow before bedtime is more than just an age-old superstition. For generations, people around the world have used this humble kitchen staple in ways that go far beyond flavoring food — and some of those traditions have surprising potential health benefits.

So, why would anyone willingly sleep with garlic at the head of their bed?

As odd as it may seem, this nighttime habit is believed to offer support for better sleep, a stronger immune system, natural congestion relief, and even insect protection. While modern science is still catching up to fully explain some of these effects, thousands swear by the results — and there may be more logic behind this practice than you think.

Let’s explore four reasons why placing garlic under your pillow might be worth trying — especially for older adults looking for simple, natural ways to support better health at night.

1. Garlic Can Help Relieve Nasal Congestion While You Sleep

If you’ve ever had a stuffy nose keep you up all night, you know how frustrating and exhausting it can be. Whether it’s due to seasonal allergies, a lingering cold, or weather changes, blocked sinuses can seriously disrupt your rest.

That’s where garlic comes in.

Garlic contains a powerful natural compound called allicin, which is released when the clove is crushed or cut. Allicin has strong antimicrobial and anti-inflammatory properties that may help fight off infections and dissolve built-up mucus in your nasal passages.

While simply placing a clove of garlic under your pillow won’t act as an overnight cure, the idea is that its subtle vapors can gradually help open your sinuses and make breathing easier during the night.

If you often wake up with a blocked nose or pressure in your sinuses, this simple remedy might be worth a try.

2. Garlic’s Natural Compounds May Strengthen the Immune System

As we age, our immune system needs all the help it can get. Garlic has long been studied for its potential to support immune function — and allicin plays a big role here as well.

Even without eating it, garlic’s natural aroma contains sulfur-rich compounds known for their antibacterial and antiviral effects. When inhaled in small amounts overnight, some believe that garlic’s vapors can help defend against minor infections, especially those affecting the respiratory system.

Although there’s limited scientific evidence on placing garlic under your pillow specifically, garlic itself has been widely recognized in nutritional science for its ability to help:

• Inhibit the spread of harmful bacteria
• Reduce inflammation in the body
• Support natural detox processes

Many people who use garlic under their pillow claim they wake up feeling less groggy, more refreshed, and less prone to seasonal illnesses — particularly during cold and flu season.

3. Garlic Naturally Repels Mosquitoes and Other Insects

Here’s a practical reason that makes a lot of sense — especially during summer or in warm, humid climates.

The strong, sulfuric odor released by garlic has been shown to repel mosquitoes, flies, and other nighttime pests. Insects find the smell of garlic disorienting, making them far less likely to enter your sleeping area.

For seniors who are prone to mosquito bites — and the itching, swelling, or even infections that can result — keeping garlic nearby can offer a natural, chemical-free layer of protection.

Bonus Tip: You can also rub diluted garlic oil or garlic-infused water lightly onto exposed skin areas (such as arms or feet) to extend its mosquito-repelling benefits without using harsh commercial sprays.

4. Garlic Might Help You Sleep Better and Wake Up Refreshed

Perhaps the most intriguing claim of all is that garlic may help promote deeper, more restful sleep.

Garlic contains essential B vitamins — particularly B1 (thiamine) and B6 (pyridoxine) — which are known to support healthy brain function, nervous system balance, and hormone production. These nutrients can help:

• Reduce restlessness
• Regulate the sleep-wake cycle
• Promote natural relaxation

Additionally, garlic may have mild sedative properties due to its sulfur compounds, which are believed to calm the nervous system and help you fall asleep faster.

If you’re struggling with insomnia, frequent night waking, or simply don’t feel rested in the morning, placing garlic under your pillow could offer subtle support — especially when combined with other good sleep hygiene practices like reducing screen time and keeping your room cool and quiet.

Just be sure not to use a pillow that’s too thick, as that can block the gentle vapors that are believed to help facilitate these effects.

How to Use Garlic Under Your Pillow

The method is incredibly simple:

• Take a fresh clove of garlic (unpeeled works fine)
• Place it under your pillow — or inside a small cloth pouch if you’re concerned about odor
• Replace it every few nights to keep the potency fresh

Some people crush the clove slightly to release more of the allicin, but this can intensify the smell, so it’s a matter of personal preference.

Are There Any Risks?

For most people, placing garlic under the pillow is safe. However, some individuals may be sensitive to the odor, which can linger on bedding or irritate sinuses if the garlic is too strong or overripe.

If you share your bed with someone, make sure they’re on board with the idea — garlic isn’t exactly everyone’s favorite bedtime scent!

A Simple Tradition With Potential Health Rewards

Sleeping with garlic under your pillow might sound strange at first, but it’s a time-tested tradition rooted in both folklore and science.

From easing nasal congestion to repelling insects and possibly improving sleep quality, the benefits are subtle but meaningful — especially for those who prefer natural remedies to over-the-counter medications.

So if you’re curious, why not give it a try?

You may just find that a humble clove of garlic helps you breathe easier, sleep better, and wake up feeling a little more refreshed.
