The key to higher sleep is mendacity in your freezer. Sure, your freezer. Icing your vagus nerve, the longest nerve in your physique, could make it easier to relax and go to sleep extra simply. And all you want is an ice pack—or only a bag of frozen peas.
As the primary nerve of your parasympathetic nervous system, your vagus nerve performs a key position in your immune system, digestion, and coronary heart charge. It’s additionally straight related to your mind. Docs typically use vagus nerve stimulators to assist deal with sufferers with melancholy or epilepsy. A latest research from Boston College discovered that “firming” your vagus nerve by way of yoga and meditation led to decrease stress ranges.
OK, so clearly the vagus nerve is essential. However can icing your vagus nerve actually forestall insomnia?
The reasoning behind icing your vagus nerve
In a TikTok that at the moment has over 3 million views (and almost 700,000 likes), consumer @heyfrankiesimmons explains how icing her vagus nerve led to higher sleep. Within the TikTok, she says she beforehand struggled to fall again asleep after waking up at 4 a.m. with nervousness. Breathwork practices, vitality work, and tea consuming didn’t lull her again to sleep. Nonetheless, as soon as she began placing an ice pack on the middle of her chest for at the very least quarter-hour, she fell again asleep quicker—and extra simply. Icing her vagus nerve allowed her to relax and beat again her anxiety-ridden insomnia. And whereas many TikTok wellness traits are shaky in legitimacy, there could also be some fact to this one.
A research carried out in 2018 discovered that the applying of a chilly thermode on contributors’ necks led to a discount in stress ranges. “Chilly stimulation within the neck space could have triggered physiological mechanisms recognized to have an effect in noninvasive [vagus nerve stimulations] VNS,” the researchers notice within the research. Whereas extra analysis must be completed on the impression of a chilly compress on an individual’s stress ranges, the researchers notice the outcomes of this preliminary research are promising.
What occurred after I iced my vagus nerve
As a chronically sleep-deprived individual, I have a tendency to have interaction in a wide range of unhealthy sleep behaviors. From revenge bedtime procrastination to sleeping a mere 4 hours an evening (I do know, I do know), it’s secure to say that I’m not getting one of the best shut-eye. Lately, I’ve had extra points falling asleep. I do my skincare routine, scroll by way of TikTok (once more, I do know, I do know), learn a couple of pages of a e book, and, but, I’m nonetheless awake. Whereas I’m not usually an anxious individual, my anxious ideas are likely to cascade by way of my head proper earlier than bedtime.
So I made a decision to do that hack out for myself. I used to be curious to see if it might actually calm me down and encourage higher sleep. Whereas I didn’t have an ice pack useful, I did have a bag of frozen blended berries. I plopped the bag on my higher chest and spent about 20 minutes mendacity there, taking deep breaths. (Full disclosure: I did spend a few of this time scrolling by way of TikTok.) Once I took the bag of frozen fruit off my chest, I felt calmer—and went to sleep simply that night time.
Was it only a placebo impact? Possibly. Will I be doing it it once more? Undoubtedly.
