Hitting the snooze button on the alarm clock once in a while might actually support the brain’s process of waking from deep sleep, according to a new study. People sometimes want to go right back to sleep even after the alarm goes off in the morning, using the snooze button in clocks and cell phones. Decades of previous research suggested that hitting snooze can have negative effects, both on sleep and the brain’s ability to wake up, but until now there hasn’t been any direct evidence of this, say scientists. The new study, published in the Journal of Sleep Research, assessed how common snoozing is and what effects this behaviour has on sleep, sleepiness, mood, and the brain’s cognitive abilities. Researchers found that those who snooze on an average sleep slightly shorter and feel more drowsy in the morning compared to those who never snooze. But they also saw that there were no negative effects of snoozing on the release of the stress hormone cortisol, mood, or sleep quality throughout the night. In the study, 1732 individuals answered questions about their morning habits, including how often they hit the snooze button with many – especially young adults – reporting that they use the alarm feature regularly. The most common reason for snoozing, according to participants, is feeling too tired to get out of bed when the alarm goes off. In another small follow-up experiment, 31 regular snoozers spent two nights in a sleep lab in order to measure their sleep in more detail. On one of the mornings, they were allowed to snooze for 30 minutes, and on the other, they had to get up right when the alarm went off. While in the first case, participants’ sleep was disturbed during the half hour of snoozing, most of them still got more than 20 minutes of sleep – meaning that their total night’s sleep was not affected much. In the snooze condition, no one had to wake up suddenly from deep sleep, and the snoozers performed a bit better on cognitive tests right upon waking. There were also no clear effects of snoozing on mood, sleepiness, or the amount of cortisol in the saliva. The results hint that half an hour of snoozing may not have negative effects on night sleep and could have some positive effects like a decreased likelihood of waking from deep sleep. However, researchers caution that the second experiment was small and only included people who are regular snoozers who find it easy to go back to sleep after each alarm. They say snoozing is most likely not for everyone. Jennifer Kanaan from the University of Connecticut in the US, who is another sleep scientist unrelated to the study, said the latest findings should be interpreted with caution as it could send the wrong message to people. “If you’re coming in and out of sleep for 30 minutes, after the alarm goes off the first time, you’re costing yourself 30 minutes of uninterrupted, quality, restorative sleep,” Dr Kanaan said in a statement. Instead of trying to figure out how to manipulate our alarm clocks, she says people should make a consistent good night’s sleep a greater priority and be less reliant on snooze buttons. “Simply put, instead of hitting the snooze button they should get more sleep,” Dr Kanaan said.

TV star Jonnie Irwin has admitted that he “never thought” he’d be alive to see his 50th birthday, which is next week. Irwin, 49, who is best known for presenting property TV shows A Place in the Sun and Escape to the Country, was diagnosed with terminal cancer in 2022. In January, Irwin threw an early 50th birthday party, ahead of the actual date next week, with a huge part with 170 friends and family. But in a new interview, the presenter has said he will be jetting off on holiday to Spain with his family for his actual birthday. “I never thought I’d be here,” Irwin told The Sun. “I’m really looking forward to some time with [wife] Jess and the boys.” Irwin shares three young sons with his wife, Jessica Holmes. He has been praised for his transparency about his condition, and his experiences with various cancer treatments. Since his diagnosis, Irwin has followed a strict diet and spends one to two hours a day in an O2Worx hyperbaric oxygen tent. Some studies have shown that flooding the body with oxygen does not promote tumour growth and has been linked to preventing cancer growth. In July this year, Irwin discussed his “really good” experience with palliative care, which focuses on improving the quality of life for anyone facing a life-threatening condition. Irwin said that he has been in palliative care since the day he received his terminal cancer diagnosis. He was first diagnosed with lung cancer in August 2020, but only publicly shared the news in November 2022 after the cancer spread to his brain. His hospice experience was a “delight”, Irwin said, challenging his initial perception that such facilities were “very much a boiling hot room full of people who looked frail and towards the end of their days”. In September, the presenter made his long-awaited return to TV when he hosted a new episode of Escape to the Country on BBC One. Looking back at his time in a hospice six months ago, Irwin said he was “on the cusp of death”. “Lying in the hospice, I thought I’d had it,” he told The Sun. ​​“But at my weakest point I thought, ‘This is it, this is the beginning of the end.’” ​​Irwin returned home and resumed his strict diet, drinking protein shakes and spending time in the oxygen tent to attempt to curb the growth of his cancer. “I won’t let cancer define me,” Irwin told the publication from his newly renovated home in Newcastle. “A friend of mine told me, ‘Your body achieves what your mind achieves’, and I want to live by that.” Read More Jonnie Irwin jokes he’s ‘whacked’ after attending The Streets gig in Newcastle Billy Connolly shares health update on Parkinson’s disease: ‘Every day gets stranger’ What are the symptoms of Parkinson's disease and how can it be treated?
