Another area of the brain that suffers dramatically from sleep deprivation is the hippocampus. This is a region critical for the storing of new memories. When people are deprived of sleep for even one night, their ability to memorise new information drops significantly....
It's not just your imagination -- you're more irritable when you're low on zzzzs. Sleep scientist Matt Walker explains how our nightly slumber affects the emotional centers in our brains, and why we can think of sleep as first aid for our feelings.
A heart attack unleashes immune cells that stimulate neurons in the brain, leading to restorative slumber
This finding illustrates once again the importance of sleep. Neurons are busy when we're awake; they don't stop firing in unison and they need oxygen to do their work. So blood isn't vacating the brain and there's no room for the cerebrospinal fluid to flow in and was...
Sleep deprivation affects the brain’s ability tolearn and recall information. During REM sleep, the brain is active, processing information and storing memories from the previous day. Less sleep disrupts this process because the body spends less time in this REM cycle. The following day you may...
Flat on your back, with arms by your side — this posture can cause snoring, which affects half of all adults at some point and is more common the older we get. Snoring isn't just annoying for the person next to you or in a nearby room. It can disturb your sleep and lead to thic...
