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.

Norway manager Stale Solbakken joked that if Jack Grealish could train for England then he has no cause to worry about Erling Haaland’s treble celebrations ahead of Saturday’s clash with Scotland. Solbakken understood the need for Haaland to revel in his success with Manchester City after last weekend’s Champions League final. Solbakken has taken it easy with Haaland this week, more concerned with ensuring the striker recharges, and believes a homecoming welcome will lift his star man during the Euro 2024 qualifier in Oslo. City celebrated in Ibiza after their Istanbul success against Inter before continuing the party on a bus parade in Manchester on Monday with Grealish throwing himself wholeheartedly into the fun. When asked what the Norwegian people made of the scenes ahead of a big international, Solbakken said: “I think everyone understands that and I also think it’s a good idea to do that. “Because, no matter how good you are, if you say (Pep) Guardiola is the best manager in the world and he has managed to do this treble once in Spain, once time in England, even when he had the best players representing the biggest clubs with the biggest budgets, you could think this would happen more often. But it doesn’t because it’s so, so difficult. “And I don’t think you can postpone a celebration like that. You can’t say ‘let’s meet up in the summer when these national games are over and we party’. It’s not the same because the excitement is a little bit out of your body and you have to do it then. “When he came here, he didn’t look like he had gone the Grealish way. If Grealish managed to train for England the first time, he should also manage to do it for us.” Only one of Haaland’s 53 goals this season has come on the international stage but the 22-year-old has not played for his country since September and Solbakken believes an excited home crowd will help him overcome his heavy schedule. “The biggest gift in that is the love the crowd will give him because it’s a long time since he has played in Norway and he didn’t participate in the two internationals earlier this year,” the former Wolves and Copenhagen manager said. “Obviously the Norwegian people have seen him on telly for a long time without seeing him live. I think he has had one game here in a year. “So that will probably pump him up and give him the five to 10 per cent he probably lacks due to the programme he has been through and all the feelings and emotions he has been through as well.” Haaland was missed in March as Norway took one point from their opening two Group A games against Spain and Georgia, while Scotland sealed maximum return. On the game, Solbakken said: “It’s more crucial for us than Scotland of course but no matter what, before the group started, this would always have been a key game. “But it’s more that Scotland have had a really great start. I think we played two really good games but what messed it up a little bit, even though we only got one point, is that Scotland beat Spain. “That means it looks much better for us if we can beat you and everyone is beating each other. If we win, also Spain are in trouble, because it’s two teams who can catch them.” Read More City soak it in and Nuggets strike gold – Tuesday’s sporting social Cadan Murley suspends loyalty to Man Utd to analyse Erling Haaland’s finishing Jack Grealish revels as Manchester City parade treble Manchester City’s trophy parade in pictures The sporting weekend in pictures Man City match-winner Rodri named Champions League player of the year

Josh Taylor has a point to prove when he takes on Teofimo Lopez this weekend, with the WBO super-lightweight title on the line in New York City. Taylor has not fought since February 2022, when he retained the undisputed titles with a controversial decision against Jack Catterall in Glasgow. The unbeaten Scot later vacated two of the belts and was stripped of another as he focused on a rematch with Catterall, which fell through earlier this year. The collapse of that fight led to the announcement of this one, however, with 32-year-old Taylor defending his remaining title against Lopez, a former unified lightweight champion. Lopez, 25, outpointed Vasiliy Lomachenko to win the lightweight belts in 2020, before losing them to George Kambosos Jr in 2021. The American has since bounced back from that sole professional loss with two straight wins at super-lightweight, though, stopping Pedro Campa in August and winning a debated decision against Sandor Martin in December. Here’s all you need to know. When is it? The fight will take place on Saturday 10 June, at Madison Square Garden’s Hulu Theatre in New York City. The main card is set to begin at 1am BST on Sunday 11 June (5pm PT, 7pm CT, 8pm ET). Ring walks for the main event are then due at approximately 4am BST (8pm PT, 10pm CT, 11pm ET). How can I watch it? In the US, the event will air live on ESPN and ESPN+. In the UK, Sky Sports will broadcast the fights.
