The bizarre social media trend of "mouth taping" to stop snoring can lead to "serious health harm", researchers are warning.

Celebrities and influencers including Gwyneth Paltrow, Emma Roberts, Ashley Graham, and Jimmy Fallon have all previously spoken about their adoption of the practice, which involves going to sleep with a piece of tape holding your lips closed.

Backers say it prevents mouth-breathing, which is linked to sleep-disordered breathing, including everything from snoring to sleep apnea.

However, researchers say the online fad probably has little benefit and could pose serious asphyxiation risks.

Western University's Dr Brian Rotenberg and a number of research colleagues evaluated the results of 10 separate studies into the effects of sealing the mouth while sleeping.

Two suggested that, among a subset of people with mild obstructive sleep apnea, mouth taping may be associated with some slight improvement in a standard measure of sleep apnea severity known as the apnea-hypopnea index.

However, other studies found no evidence that mouth taping might help treat mouth breathing, sleep-disordered breathing, or sleep apnea.

Four of the 10 studies included discussion of a potentially serious risk of asphyxiation for people whose mouth breathing is caused by serious restriction or blockage of nasal airways.

Serious nasal obstruction could result from conditions such as hay fever, chronic rhinitis, deviated septum, sinonasal disease, or enlarged tonsils.

The authors of the new survey, published in the journal PLOS One, found the evidence currently supports the practice of mouth-taping, but said further research was needed.

"Mouth taping is a contemporary practice that is often celebrity-endorsed, but is not necessarily scientifically accurate," the authors said.

"Many people are not appropriate for mouth taping, and in some cases it can lead to risk of serious health harm."

"There are over eight billion people that call this planet home. There are seven of us that can say the same for space station."

Arafath Mannan was blindsided to receive a notice that would be illegal in NSW today.

The now 38-year-old moved into a home in Riverwood, in south-west Sydney, in 2017.

He remained there through several full-time jobs, surgeries, the COVID-19 pandemic, being made redundant, getting married and the birth of his daughter.

The father renewed his lease in August last year and copped a rent hike, which brought the weekly total up from $650 to $720.

Mannan struggled to keep up, but his situation deteriorated after he was hit with a no-grounds eviction notice just two months later.

The no-grounds eviction notice, seen by 9news.com.au, meant that Mannan was not given a reason why he had to leave, but had 90 days to do so.

Mannan said he was blindsided.

"I just didn't know what to do, literally, because I know how the market is," he said.

"I just was thinking that I was secure, because my rent went up two months ago… the lease period just started."

Mannan was told the owner planned to move in and renovate the home.

But, in the months after the eviction, he discovered the Riverwood property was back on the market at the same price.

"They kicked me out, the owner did not move in, and they tried to put the property back in the market, exactly the same price," he said.

"What have I done wrong? I was actually hurt. It just felt personal. They just kicked me out for no reason whatsoever." 

After some time on the market, the property's rent was reduced to $700 per week.

Mannan luckily found another rental just 150 metres down the road from his former address.

In the end, he lost about $630 of his bond to repairs and over $300 for moving fees.

New rental reforms that ended no-grounds evictions came into effect in NSW this week.

Now, agents and landlords are required to provide a specific reason for eviction, including a tenant breaching their lease, damaging the property or not paying rent, the landlord wanting to sell the property or the property no longer being used as a rental.

Agents and landlords who fail to comply will be dealt with under the Rental Taskforce. 

"For too long, renters have lived with the fear of being kicked out for no reason. That ends today," Housing and Homelessness Minister Rose Jackson said earlier this week.

While the changes were welcomed by some, Mannan said he did not believe they would have much material change because landlords could still decide to increase the rent, effectively evicting tenants who cannot afford the hike, or sell the property.

"I know, in the paper and in the books, it looks really nice… but it doesn't secure us. We need more property to be built, it's a simple solution. There's no supply," he said.

Kermit the Frog knows it's not easy being green — or graduating from college and entering the real world, especially during a time of economic uncertainty and political turmoil.

Members of the University of Maryland's class of 2025 received their diplomas on Thursday evening (Friday AEST) with sage advice from the amphibious Muppet ringing in their ears.

"As you prepare to take this big leap into real life, here's a little advice — if you're willing to listen to a frog," the beloved Muppet said.

"Rather than jumping over someone to get what you want, consider reaching out your hand and taking the leap side-by-side, because life is better when we leap together."

The university announced in March that Kermit, who was created in 1955 and became the centerpiece of the Muppets franchise, would be this year's commencement speaker.

He is also no stranger to the school.

Muppets creator Jim Henson graduated from Maryland in 1960. A home economics major, he fashioned the original frog puppet from one of his mother's coats and a Ping-Pong ball cut in half, according to a statement from the university. Henson died in 1990.

A bronze statue of Henson and Kermit sitting on a bench is a well-known feature of the College Park campus.

In a video announcing the speaker pick, Kermit is described as an environmental advocate, a bestselling author, an international superstar and a champion of creativity, kindness and believing in the impossible.

His speaker bio calls him "a star of stage, screen and swamp" whose simple mission is to "sing and dance and make people happy".

"I am thrilled that our graduates and their families will experience the optimism and insight of the world-renowned Kermit the Frog at such a meaningful time in their lives," university President Darryll J. Pines said in a statement.
