A thing as simple as a comb is not just useful for untangling the hair. It has always been a favourite tool for DIY websites, and most recently, a Facebook post shared another hack you can use combs for – to deal with delivery pain.

Fox Valley Birth and Baby, a Wisconsin-based photography and birth coaching business, shared a post of a woman holding a comb during labour. According to their post, holding a comb in hands give the acupuncture effect.

It works on the simple ‘gate control pain theory,' which states that your brain can focus on a select number of sensations. And since the nerve endings are closer in your hands, they reach the mind faster. Thus, helping your body forget about the contractions. There's a technique to holding the comb - it needs to hit the base of the fingers with the teeth pressing into the palm of your hand.

The post has already got around 23,000 comments, more than 6,000 likes, and 20,000 shares. While some commenters support the theory and said they would carry a comb to their delivery room, others laughed at it. Some also said that they use it for bearing other pains, too.

One person commented, “I do this when I get a tattoo! 👏🏻👏🏻👏🏻 totally works.”Another wrote, “Wish I would have known about this!!! So cool!!”

So, what does the comb exactly do? In acupressure, thumb, fingers, or small beads are used to apply pressure on certain nerves to stimulate specific points on the body. It is one of the drug-free techniques many people use to relieve pain and to relax.

It is an excellent technique for women wanting to have a natural delivery, without the intervention of any medications. The fingers or any other object hits these pressure points and triggers the release of brain chemicals like endorphins, which help block pain signals.

Now, when a comb is held in hand correctly, it also activates these pressure points. Daryl Nicole Thuroff, a licensed acupuncturist at the Yinova Center in New York says, “A few good ones to target during labour can be found in the center of your palm: When you make a fist, one is located where the tip of your pinky finger lies, while another is where the tip of your middle finger meets your palm.”

Dr. Christine Greves, M.D., an OB-GYN at the Winnie Palmer Hospital for Women & Babies in Orlando, Florida says, “If you want to try the comb, try it. But don’t give yourself a hard time if it doesn’t provide you relief. Go into the delivery process with an open spirit. Not everything is meant for everyone!”

This hack might not work for everyone. But it’s worth a try during a painful situation.
