Cory shares health the benefits of sleeping with mouth taped however, not everyone is convinced with his explanation and are skeptical over the details shared.
Cory L Rodriguez is a health coach and 'wellness expert' who took to TikTok to share why he tapes his mouth shut every night. Cory explained that it not only improves oral health but greatly helps in sleeping.
Cory regularly shares health advice on social media including TikTok and Instagram.
In one of his latest videos, he advocates taping your mouth shut every night, saying it has a variety of health benefits.
He explains: "I tape my mouth shut every night before I go to sleep.
"Let me show you why - and it's not because my wife wants me to stop talking!"
Cory explains in the video that he uses special mouth strips but only if you cant get hold of any then you can make use of medical tape too.
He continues: "I'm using mouth strips that are actually made for this, but a lot of people can use gentle paper medical tape, that will work.
"But you do not want to use duct tape as it can harm the lips."
He then demonstrates how to apply the strip, gently placing it over his closed lips, before going on to talk about why he does it.
"The goal is to breathe through your nose while you're asleep, versus your mouth," he says.
"This is going to help your oral health, it's going to help your sleep, it's going to help dry mouth, snoring - because you are humidifying and moisturising the air."
His video has received more than 2.7 million views and more than 130,000 likes.
Many people have commented on the post and most of them are not convinced by the method.
One person commented: "I am too afraid to have my nose clogged and end up dying."
He replied: "Honestly my nose was always clogged, but I got used to it. Nasal strips also help."
Various YouTube videos and articles online recommend using specialized strips from brands like Somnifix or Snorless.
But like him, James Nestor - author of Breath: The New Science of a Lost Art - also says you can use cheaper alternatives, and tends to just use inexpensive micropore tape.
Speaking to CNN, he said: "I'm a big fan of American entrepreneurialism, but I don't think you need a special tape to tape your mouth with."
Nestor continued: "Just a teeny little bit at the centre of your lips. The point is not to inhibit airflow through your mouth, it's to train your jaw shut at night."
Saying the method has been a 'complete game changer', he added: "I travel with [tape] whenever I travel, even when I go camping. I'm convinced it's a good thing, and I've talked to the experts who have told me the same.
"It's been a complete game changer."
Not everyone was satisfied with Cory's explanation, however. Dr. Kathleen Yaremchuk, a sleep specialist in Detroit, told the BBC: "If you were to get sick and you had to vomit, you wouldn't be able to."
Many professionals also advised the news outlet against mouth taping being used by children.
