No one is telling you what time to go to bed with this, but researchers are making a strong case that the duration and timing of your sleep are closely associated with whether your behavior is heart-healthy. Night owls should take special note of a new study that found the early-to-bed, early-to-rise approach aligns much better with cardiovascular health.

Sleep loss detrimental to blood vessels

Sleep deprived

We all know lack of sleep is bad for the brain, but lack of sleep has even been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Worse still, researchers in a new study have found that sleep loss also influences cholesterol metabolism.

How the brain consolidates memory during deep sleep

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, a central question of inquiry in neuroscience. Neuroscientists say they now may have an answer to this question in a new study that provides for the first time a mechanistic explanation for how deep sleep (also called slow-wave sleep) may be promoting the consolidation of recent memories.

Sleep not just protects memories against forgetting, it also makes them more accessible

neuroscience Sleep makes our memories more accessible

Sleeping not only protects memories from being forgotten, it also makes them easier to access, according to new research from the University of Exeter and the Basque Centre for Cognition, Brain and Language. The findings suggest that after sleep we are more likely to recall facts which we could not remember while still awake.

Babies who can resettle are more likely to ‘sleep through the night’

Babies sleeping next to each other

Good news, for parents who see their babies “resettle” when they wake up. According to a video study, young infants who can “resettle” themselves after waking up are more likely to sleep for prolonged periods at night. Okay, maybe that’s bad news for parents who don’t have a baby who “resettles,” but it’s still good information.

Sleep may be critical to avoid miscarriage

If you are trying to have a baby, a good night’s sleep is more important than ever. A recently published research report shows that the womb has its own “body clock” that needs to synchronize with the mother’s body clock to ensure optimal conditions for fetal growth and development. The inability of a mother’s body clock to synchronize with the womb’s clock may be at least part of the reason why some women have difficulty carrying a pregnancy to full term.

Hyper sleep- A “down to earth” space story

hyper sleep

It was every kids’ dream to go into space, not understanding the perils or the boredom that comes with it. The idea of floating weightless and “boldly going where no man has gone before” permeated the imagination as nothing had ever done before. Space, why did there have to be so much of it?
