Rub Vicks VapoRub on your feet before bed — here’s what happens

When it comes to a persistent cough, studies suggest that applying Vicks VapoRub to your chest and throat can actually help quiet that cough, potentially leading to a better night’s sleep. It’s pretty interesting how that works. Menthol, in particular, acts as a bronchodilator. Think of it like opening up little airways – the bronchi and bronchioles – that allow oxygen to get down into your lungs. When you combine eucalyptus, menthol, and camphor, they can work together to open up your sinuses. You can even get some of this benefit just by inhaling the vapors for a few minutes, without even putting it on your body.

The Unexpected Foot Trick

Now, here’s the part that might surprise you. When you’re really struggling with a cough and can’t get any rest, try this: take some Vicks VapoRub and apply it to the soles of your feet. Yes, your feet! The menthol, camphor, and eucalyptus in the rub stimulate nerve endings in your feet. These nerves then send signals, or afferent messages, up your legs, through your thighs and buttocks, and all the way up your spine. Eventually, these signals reach a very important part of your brainstem called the medulla oblongata.

Key Takeaways

• Camphor, Eucalyptus, and Menthol: These are the primary active ingredients in Vicks VapoRub, known for cough suppression and pain relief.
• Chest and Throat Application: Applying the rub to the chest and throat can help reduce coughing, promoting better sleep.
• Inhalation Benefits: Simply breathing in the vapors can help open up sinuses.
• Foot Application: Applying the rub to the soles of the feet can stimulate nerve endings that send signals to the brainstem, potentially inhibiting the cough reflex.

The medulla oblongata is located at the very bottom of your brain, where your brain and spinal cord connect. It’s like a central hub for nerve signals going to and from your body. This area controls some really vital functions, including your heartbeat, breathing, and blood pressure. Importantly for us, it also plays a role in controlling the cough reflex.

So, by stimulating those nerve endings in your feet, you’re sending messages up to the medulla oblongata. This stimulation can actually help to calm down that urge to cough. It’s a fascinating way that our bodies respond to these topical applications. If you’re not keen on using Vicks VapoRub, you could try products containing eucalyptus, camphor, or menthol separately. You might be surprised at the results.
