Sleep cycles are a very interesting and fickle thing. Things like stress levels, body temperature, and room temperature play a huge role in this process. Researchers from Germany have asserted that new technology present in a piece of wrist wear could potentially record real-life sleep habits and patterns that could impart necessary knowledge that would be able to improve the resting hours of many individuals.
Sleep issues creep up on people at different points of their lives. When I was in college, I couldnt stay asleep in bed for more nights then Id like to admit. The problem was so persistent that it drastically impacted my studies. Research shows that long-term sleep deprivation causes serious health conditions such as obesity, diabetes, heart disease, stroke, and Alzheimers disease. After seeking medical help, it was evident that poor sleeping habits was one of the contributing factors to my challenges getting quality sleep.
When you suffer from sleep apnea, not only is your brain potentially more exhausted because of those patterns of breathing that are compromised, but it affects on a huge level how you react when you are going about your day. Lack of good, sound sleep can contribute to poor mood and even extreme emotions. When you're tired, it's hard to regulate normal experiences that you'd be better suited to deal with when you have had the proper amount of sleep. You may become overly reactive to something that you wouldn't otherwise simply from sheer fatigue and exhaustion.
The groups physiological studies indicate that sleep loss shifts the hormonal balance from hormones that promote fullness, such as GLP-1, to those that promote hunger, such as ghrelin. Sleep restriction also increased levels of endocannabinoids, which is known to have appetite-promoting effects. Acute sleep loss also alters the balance of gut bacteria, which has been widely implicated as key for maintaining a healthy metabolism. The same study also found reduced sensitivity to insulin after sleep loss.
Sleep disturbances are common in dementia but little is known about the various stages of sleep and whether they play a role in dementia risk, explains study author Matthew P. Ease PhD. We set out to discover which stages of sleep may be linked to dementia and while we did not find a link with deep sleep, we did with REM sleep.
