Study explains THC can help young adults with depression or anxiety but otherwise could worsen sleep problems
Many insomniacs swear by cannabis as a way to help them sleep – while many scientific studies have found that THC actually exacerbates sleep problems.
A new study published last week in Addiction might explain why.

People living in deprived areas of the UK have poorer sleep quality than those in affluent areas, the first large-scale study of sleep across the population has found.
Black people reported the worst sleep overall, with the research finding both social deprivation and ethnicity affect sleep quality, irrespective of age, sex, personal wealth, employment and education.

Light and noise are “neglected pollutants” that are causing significant harm to human health and can cause premature deaths, a group of peers have said.
The science and technology committee of the House of Lords has called on ministers to do more to tackle these pollutants, which it claims are “poorly understood and poorly regulated”.

Seals dozing on the beach may appear to be enjoying the ultimate life of leisure. However, groundbreaking research has revealed that for most of their lives elephant seals sleep just two hours daily in a series of short naps while performing deep dives.
The findings, revealed in the first study to record brain activity in a free-ranging, wild marine mammal, show that during the months they spend at sea, elephant seals rival the record for the least sleep among all mammals, currently held by African elephants. The seals were found to typically sleep in 10-minute bursts during deep, 30-minute dives, often spiralling downwards while dreaming, and occasionally lying down for a nap on the seafloor.

About half of all hospital doctors and nurses have had accidents or experienced near misses while driving home after a night shift.
The risks they pose to themselves and other road users have been calculated as the same as those posed by drivers who are over the legal alcohol limit, delegates at a European medical conference were told last week.

• See all our coronavirus coverage
Trapped inside a house, stuck inside a vehicle that wouldn’t move, unable to complete seemingly simple tasks: this was the stuff that dreams were made on during lockdown, according to new research from University College London.
Analysis of more than 850 dreams and nightmares submitted online to the Lockdown Dreams Project between March 2020 and March 2021 shows people often dreamed about having frustrating and restrictive experiences in mundane, everyday settings, like the home, at the height of the pandemic.

Sleeping with the light on might scare away monsters under the bed, but it could be linked to an increased risk of heart disease and diabetes, research suggests.
Light is an important signal by which the body’s internal clock, which governs a host of biological processes from temperature to hormone release, is synchronised to the external cycle of day and night.

Name: Sleep deprivation.
Age: Dates to somewhere around the early 19th century. Before that, nobody knew how much sleep they were supposed to get, so they didn’t feel deprived.

Everything about our day impacts our sleep. How many minutes we spend outside, what and when we eat, what’s happening with our hormones, our habits, emotions, stress and thoughts – all this feeds into the sleep we end up with at night. All of which I was completely oblivious to when battling chronic insomnia for years on end.
Sleep anxiety can create a very real and vicious circle. I would spend hours lying in bed, increasingly wired, anxious and exhausted as time ticked by, with prescription sleeping pills within reach for those 3am nights when I had to be up first thing. The problem is that the more we worry about sleep, the higher our stress hormones go – and too much of the stress hormone cortisol, whatever the trigger, disturbs our sleep. We’re left in a state of fight or flight, when we need to be in the opposite state of rest and digest. When my insomnia was at its worst, I’d start my day exhausted, running on empty, and have recurring burn-out days, where an overwhelming fatigue would stop me in my tracks, forcing me to lie down and recharge.

A three-hour break in the middle of the working day for a languorous lunch, followed by a restorative nap sounds like the Mediterranean dream, but employers in Spain are increasingly moving away from this rigid schedule, which for many workers feels more like a nightmare.
The merits of introducing the siesta in the UK have been hotly debated this week after the National Trust unveiled plans to move towards “Mediterranean working hours” at some sites in the south-east, to help cope with rising annual temperatures.

By the time her baby was four months old, Zara, a psychologist and executive coach from Surrey, was able to open a bottle of wine and have “a bit of an evening”. He was sleeping in four-hour stints, waking twice in the night. Then, at four and half months, his sleep pattern changed: “It was five wakes, then six, then eight,” Zara says. She was so exhausted she ended up Googling “can you die from sleep deprivation?”.
“I was broken, emotional, confused, sleep-deprived and catastrophising,” she says. “He wouldn’t be down for longer than 20 minutes, and I was losing my mind. Using a sleep consultant was the best money I’ve ever spent; £250 to give me the confidence to trust my child to get himself to sleep without me.”

Vomiting on the bed. Snoring. The shedding of hair. The stealing of sheets. The passing of wind. Night-time face-licking. A higher-than-average chance of catching sarcoptic mange …
If I could sit my dog down and quietly explain the risks associated with him sharing the bed with us, this is the list I would read to him. But I know he wouldn’t listen. Oz, our young lurcher, would only warmly reimagine that scene he recently saw. When, on my birthday, the family let him come upstairs and on to the bed to wake me up. When he saw, for the first time, Upstairs Land. And then widdled with joy.

People who regularly sleep for six hours or less each night in middle age are more likely to develop dementia than those who routinely manage seven hours, according to a major study into the disease.
Researchers found a 30% greater risk of dementia in those who during their 50s, 60s and 70s consistently had a short night’s sleep, regardless of other risk factors such as heart and metabolic conditions and poor mental health.

There is something visionary about this near-nonsensical, kitsch but atmospheric techno-thriller from Canadian director Anthony Scott Burns. Drawn along on dark somnambulic rhythms, it incorporates elements of fantasy, horror and 80s synthwave aesthetics without giving itself over completely to any of them.
A wordless first 10 minutes introduces us to Sarah (Julia Sarah Stone), a runaway student apparently unwelcome or unwilling to return home, waking in spectrally lit parks and falling asleep in coffee shops. Dropping suddenly into surrealistic CGI dreams that track inexorably towards a demonic figure who, if approached too closely, wakes her with a start. Sarah decides to try and climb out of this insomniac bath by enrolling in a university sleep study. It is overseen by Dr Meyer, a Cronenbergian academic in big glasses, but run by a trio of researchers who, like the memory technicians in Eternal Sunshine of the Spotless Mind, have a loose relationship with scientific protocol. Becoming close to Jeremy (Landon Liboiron), she learns that they are using pioneering technology to observe the subjects’ dreams – and that the same shadowy presence manifests in all of them.

For as long as she can remember, Jenny Carter has gone to bed late and not woken up until late the following morning, sometimes even the early afternoon. Growing up, she didn’t have a bedtime, and at university she preferred to write her essays between 6pm and 10pm. She loves evenings. They’re when she feels the most creative and can concentrate the best. But that’s not when her employer or society expects her to be productive.
“Going to bed at a ‘normal’ time feels so unnatural to me,” she says. “But society just doesn’t cater for people whose sleep cycle doesn’t fit the generic 9 to 5.” She has got into trouble at work for her timekeeping, which has led to disciplinary action. “I’ve had to write off so many events, meetings and opportunities, because they were in the morning and I just knew I wouldn’t be awake.”

When I was a kid, I thought that monsters came out of the dark. Turns out, they actually come out of the light. Like you, I run my life on the supercomputer in my pocket. At night I would place it under the pillow and struggle to put it out of mind, its bright screen a portal to other worlds.
Sure, most of Twitter is bile, but social media suits my exhibitionist spirit; I want to be front and centre of whatever conversations are happening. As a journalist, I am meant to be. When I said I wanted to get my phone out of my bedroom, a colleague half-jokingly asked : “What if something happens?”
