Importance of Sleep and your general health
(Summary of article by Dr.Mercola 0n the subject )
Sleep plays a key role in everything from gene expression and hormone regulation to brain detoxification and cognition, it becomes clear that there aren’t many facets of your being that can skate by unscathed when you skimp on sleep
• Sleep impacts your ability to learn and your creative capacity. Deep sleep is also crucial for brain detoxification, and can have a significant impact on your risk for Alzheimer’s disease
• Sleep allows your brain to consolidate abstract pieces of information, collating them into cohesive patterns that allow you to make sense of the world around you, and your experiences of it
• Sleep is important before learning, as it helps prepare your brain to soak up new information. It’s also crucial after learning, at which point the data are saved and integrated with what you already know
First, sleep is important before learning, as it helps prepare your brain to soak up new information. Walker’s research shows that sleep-deprived students have a 40 percent reduction in their ability to retain new information, compared to those who got a full eight hours of sleep.
•Second, you need sleep after learning, to properly save and hold on to those new individual facts — and integrate the new information with what you already know.
How Lack of Sleep Affects Your Heart and Cardiovascular Health
Importantly, research shows sleep is a significant factor in heart and cardiovascular health. For example, lack of sleep:
*Prematurely ages your heart
*Raises your blood pressure and promotes vascular inflammation
Sleep Deprivation Fuels Feelings of Loneliness
Walker also discusses some of his more recent research,8,9,10 which suggests loneliness may be closely tied to lack of sleep.
Loneliness has reached crisis proportions in the U.S. and has severe health consequences. For example, loneliness increases your all-cause mortality risk by a whopping 45 percent, Walker says, and he believes sleep deprivation may actually be a significant underlying factor. The good news is this is something you have a lot of control over and can do something about.
It’s also worth noting that, according to Walker, they’ve been unable to find a single psychiatric disorder in which sleep does not play a role, which really highlights the importance of addressing sleep whenever you struggle with any kind of mental health problem, be it mild or severe.
