There are also less obvious repercussions of sleep deprivation that make a case for conceding to our bodies’ need for regular, full nights of rest.
Lack of sleep can have serious consequences:
• Increased risk of daytime accidents
• Increase in body mass index – a greater likelihood of obesity due to an increased appetite caused by sleep deprivation
• Increased risk of diabetes and heart problems
• Increased risk for psychiatric conditions including depression and substance abuse
• Decreased ability to pay attention, react to signals or remember new information
We know that – beyond making us feel bad — all of these negative outcomes can be connected to lack of sufficient sleep. But don’t you ever wonder why? What are our bodies actually doing while we sleep?
Sleep Cleans Our Brains
A recent scientific study involving mice might finally bring us to a true understanding of the biological function of sleep. Scientists found that sleep allows the brain to clean itself of by-products built up from neural activity during the day. This is a completely different mode of functioning than what happens in our brains while we are awake and alert. While we doze, cerebral spinal fluid pumps through the brain’s tissue, flushing waste into the circulatory system until it eventually reaches the liver. Without this cleaning period, toxic proteins that can lead to “dirty brain” disorders such as Alzheimer’s can build up in the brain.
The right mattress can have a big impact on whether or not you sleep sufficiently to meet your body’s needs. A four-year study conducted by researchers at Duke University showed that picking the right mattress for your body can impact your sleep cycle. Small variations in levels of firmness affect quality of rest — and can determine how much time your brain has for it’s nightly cleaning.
