We’ve been hearing about the dangers of too little sleep for years. With 70 million Americans suffering from sleeping disorders, risks of depression, obesity, anxiety, and psychological disorders increase when we get less than seven hours a night. Even memory problems form when we don’t dream enough, which relies on achieving enough cycles of REM sleep—also dealing with duration.
There’s always two sides to every story. You can die of thirst or drink too much water. Same goes for sleep. The world’s largest sleep study has just wrapped up, offering balance to how we usually treat sleep: Too much is no good either.
Published in the journal Sleep (where else?), the researchers gathered data from over 10,000 people from across the planet. Western University Brain and Mind Institute researchers launched this study in June 2017; over 40,000 volunteers initially signed up. They filled out questionnaires and performed a series of tests to monitor their cognitive abilities. As Western researcher Adrian Owen (located in London, Ontario) says:
People who logged in gave us a lot of information about themselves. We had a fairly extensive questionnaire and they told us things like which medications they were on, how old they were, where they were in the world and what kind of education they’d received because these are all factors that might have contributed to some of the results.
The study cites a survey of over a quarter-million people, in which 29.2 percent of respondents claimed to sleep less than six hours per night; even partial sleeping disorders cost the Canadian economy $21.4 billion each year. Since basic cognitive functioning requires collaboration from numerous systems, reasoning and verbal skills suffer when you sleep too little—or too much, they note. Sure, less than seven hours per night is problematic, but so is more than eight hours, they found.
The Cambridge Brain Sciences 12-point online test covers a wide application of cognitive abilities, including spatial working memory, reasoning, planning, cognitive flexibility, and visuospatial working memory. A total of 10,886 participants, including 6,796 women and 4,013 men (average age of 41.7 years), were assessed. The optimal amount of sleep for reasoning, verbal, and overall abilities, turned out to be 7.16 hours.
Interestingly, despite a popular myth, age does not have an impact on required sleep. We don’t actually need less sleep as we grow older; in fact, the authors write, sleeping less as you age could aid in diseases of dementia and age-related cognitive decline. As researcher associate and lead author Conor Wild says, it’s all about how long you spend unconscious.
We found that the optimum amount of sleep to keep your brain performing its best is 7 to 8 hours every night and that corresponds to what the doctors will tell you need to keep your body in tip-top shape, as well. We also found that people that slept more than that amount were equally impaired as those who slept too little.
One bright spot for those who like to sleep in: A single night of “oversleeping” results in better-than-usual performance on these tests. And the bad news for those suffering from lack of sleep continues: Sleeping less than four hours per night is the equivalent of aging almost eight years.
These results matter, not just for one’s general health, but for the functioning of society. As the authors conclude:
These findings have significant real-world implications, because many people, including those in positions of responsibility, operate on very little sleep and hence may suffer from impaired reasoning, problem-solving, and communications skills on a daily basis.

Does the idea of mingling at a party send cold fingers of dread creeping up your spine? Or the thought of giving a presentation in front of a room full of people make you feel physically sick?
For example, a shy child may be more likely to isolate themselves in a playground and watch everybody else rather than engaging. That then makes them feel more comfortable being on their own because that becomes their common experience.

If you’re anything like me, the think-pieces you’ve read on how to spot red flags or deal with a friend’s trauma dumping will have become imprinted on your brain. However, it’s also true that sometimes we need to look at the relationship we have with ourselves before analysing the relationships we have with others.
You struggle with self-care and putting your needs first

Of course, this is ridiculous. You cannot easily force yourself to forget something or someone. In fact, the more you try, the harder it becomes. But you can stop yourself from reliving those memories. This is what lies at the heart of this week’s question. When something bad happens to you — something traumatic, even — how far should we try to move on and how far should we try to unpack our past? I do not have a psychology degree, and I am not a psychotherapist, so I will approach this from a philosophical point of view and ask: How important is our past to our future? Should Kant try to forget Lampe or carry his memory as part of him? Should Dee let go of the past or dig it up and face it down?





We should probably pin down what we mean by loneliness, as opposed to solitude, aloneness, social isolation, disconnectedness etc. For Henry Rollins, the former Black Flag frontman turned writer, it’s something that “adds beauty to life. It puts a special burn on sunsets and makes night air smell better.” I’m going to file that under Poetic Nonsense. The Campaign to End Loneliness (CEL), more usefully, defines it as “a subjective, unwelcome feeling of lack or loss of companionship. It happens when there is a mismatch between the quantity and quality of the social relationships that we have, and those that we want.”
Not only do animals provide us with unconditional love and support; they also help to give structure to our days and even encourage us to get out and connect with others. Interaction with pets is also shown to help reduce stress levels.



The late actor Chadwick Boseman found calm in the sound of a djembe drum, said Viola Davis in an interview with USA Today. “One of the things that he carried everywhere was his djembe drum, which is called a talking drum in Africa. And he carried it himself,” Davis remembered about her Ma Rainey’s Black Bottom co-star: “He said ‘Viola, wherever I go, I carry my djembe drum. I do it for me. I play this drum for me, for my healing.’ It felt like he was playing that for God, for himself. There are no words to describe the playing because I love the djembe drum, but listening to him play when he had breaks in that trailer was just phenomenal.”
