Feeding your baby solids early may help them sleep, study suggests | Life and style | The Guardian
More than 1300 healthy breastfed three-month-olds were split randomly into two groups in one the babies were exclusively breastfed until they were six months old – as current guidelines recommend – while children in the other group were breastfed and given solid foods, including peanuts, eggs and wheat, from the age of three months, in addition to breastfeeding. After six months babies in both groups were eating a range of solids.

The children’s health and behaviour was followed for three years, with their sleep and consumption of solid food tracked by families through questionnaires.

While not all babies were kept to their allotted regime, on average, babies who were in the breastfeeding only group were first introduced to solids at around 23 weeks, while those in the other group encountered the foods at around 16 weeks

The results, based on data from 1,162 infants and taking into account factors such birth weight and whether children had eczema, reveal babies introduced to solids from three months slept, on average, two hours more a week at the age of six months, than the babies who were only breastfed. They also woke around two fewer times at night per week at six months and had just over 9% fewer incidents of waking up during the night over the course of the study.

The team found that the more closely parents stuck to the early introduction programme, the stronger the effect.

Eat yourself to sleep: the foods that can help get a good night’s rest | Life and style | The Guardian
the study was also “supported” by the world’s largest marketer of kiwi fruit, and had just 24 participants. Kiwis do have high levels of serotonin, which is critical to sleep – but what other foods could help?
Poultry and nuts

Turkey and chicken contain high levels of tryptophan, which also boosts serotonin. “Foods that are high in tryptophan and vitamin B6 will help you make melatonin, the sleep hormone,” says Nerina Ramlakhan, sleep expert and author of Fast Asleep, Wide Awake. Other good sources of both are beans, lentils, cheese, tofu, tuna, eggs, whole grains, nuts and seeds.

The shorter your sleep, the shorter your life: the new sleep science | Life and style | The Guardian
It’s his conviction that we are in the midst of a “catastrophic sleep-loss epidemic”, the consequences of which are far graver than any of us could imagine. This situation, he believes, is only likely to change if government gets involved.

What is the neuroscience behind empathy? When do children develop it? And can it be taught?
Listen

Walker has spent the last four and a half years writing Why We Sleep, a complex but urgent book that examines the effects of this epidemic close up, the idea being that once people know of the powerful links between sleep loss and, among other things, Alzheimer’s disease, cancer, diabetes, obesity and poor mental health, they will try harder to get the recommended eight hours a night (sleep deprivation, amazing as this may sound to Donald Trump types, constitutes anything less than seven hours)

This 10-Minute Routine Will Increase Your Clarity And Creativity
It’s common practice for many of the world’s most successful people to intentionally direct the workings of their subconscious mind while they’re sleeping.

How?

Take a few moments before you go to bed to meditate on and write down the things you’re trying to accomplish.

Ask yourself loads of questions related to that thing. In Edison’s words, make some “requests.” Write those questions and thoughts down on paper. The more specific the questions, the more clear will be your answers.

While you’re sleeping, your subconscious mind will get to work on those things.

Your Ancestors Didn’t Sleep Like You – Are We Doing It Wrong? | Collective-Evolution
Evidence continues to emerge, both scientific and historical, suggesting that the way in which the majority of us currently sleep may not actually be good for us.

In 2001, historian Roger Ekirch of Virginia Tech published a paper that included over 15 years of research. It revealed an overwhelming amount of historical evidence that humans used to in fact sleep in two different chunks. (1)

In 2005, he published a book titled “At Day’s Close: Night in Times Past,” that included more than 500 references to a disjointed sleeping pattern. It included diaries, medical books, literature and more taken from various sources which include Homer’s Odyssey all the way to modern tribes in Nigeria and more.

Couples sleep in sync when the wife is satisfied with their marriage
couples are more likely to sleep in sync when the wife is more satisfied with their marriage.

Results show that overall synchrony in sleep-wake schedules among couples was high, as those who slept in the same bed were awake or asleep at the same time about 75 percent of the time. When the wife reported higher marital satisfaction, the percent of time the couple was awake or asleep at the same time was greater.

"Most of what is known about sleep comes from studying it at the individual level; however, for most adults, sleep is a shared behavior between bed partners,"

Ian Parker: The Search for a Blockbuster Insomnia Drug : The New Yorker
After adjusting for age, gender, smoking habits, obesity, ethnicity, alcohol use, and a history of cancer, and after controlling, as much as possible, for other diseases and disorders, Kripke found that people who had taken sleeping pills were more than three times as likely to have died during the study period as those who had not. Those on higher doses of the drugs were more than five times as likely to have died.

How Little Sleep Can You Get Away With? - NYTimes.com
Gregory Belenky, then director of the division of neuroscience at the Walter Reed Army Institute of Research in Silver Spring, Md., was running a similar study. He purposely restricted his subjects to odd numbers of sleep hours — three, five, seven and nine hours — so that together the studies would offer a fuller picture of sleep-restriction. Belenky’s nine-hour subjects performed much like Dinges’s eight-hour ones. But in the seven-hour group, their response time on the P.V.T. slowed and continued to do so for three days, before stabilizing at lower levels than when they started. Americans average 6.9 hours on weeknights, according to the National Sleep Foundation. Which means that, whether we like it or not, we are not thinking as clearly as we could be.

Neuroskeptic: Why Do We Sleep?
dolphins sleep half their brain at a time, never lose consciousness completely, unlike for example certain bats who sleep for 20 hours/day.
Why? Otherwise we'd be doing stuff all the time.
