How Is Sleep Linked to Life Span of A Person

Would you prioritize sleep if you knew it kept your immune system strong? That’s the question the American Academy of Sleep Medicine wants you to ponder this week.

Statistics in recent journals show that people who are sleep-deprived not only are tired during the day and suffering from a lack of concentration, but they also are increasing their risks for obesity, congestive heart failure, and diabetes – amongst other conditions. More and more, people are realizing that sleep plays a very important role in your overall health and physical condition.

“Not enough sleep leads to a wake,” the Mirror reported. It said that sleeping less than six hours a night makes you 12% more likely to die prematurely than someone who sleeps up to eight hours. “Not enough sleep leads to a wake,” the Mirror reported.

A study named Diurnal Rhythms in Blood Cell Populations and the Effect of Acute Sleep Deprivation in Healthy Young Men showed that Researchers at the Erasmus MC University Medical Center in Rotterdam, the Netherlands, and the University of Surrey in the UK measured white blood cell counts in young men who sleep eight hours and men whose sleep was restricted, and found a spike in white blood cells, particularly those called granulocytes, released in response to immune system threat.

Many studies show that sleep deprivation lowers your life expectancy. Harvard Medical School experts recently revealed that people who get less than 5 hours of sleep are 15 percent more likely to die at any age, from anything. In the “Whitehall II Study,” British researchers discovered that less than five hours of sleep also doubled the risk of death from cardiovascular disease – which is the number one cause of death in America according to the CDC.

Sleeping less also causes weight loss from your ideal weight. A 2004 study shows that people who sleep less than six hours per day were about 30 percent more likely to gain weight and become obese than those who slept six to nine hours. Leptin – the hormone that makes you feel full and regulates fat storage – is 15.5 percent lower in those who regularly sleep five hours or less. Conversely, less sleep also increases ghrelin, which is the hormone that stimulates hunger. In short, you’ll feel hungrier and less full throughout the day, naturally leading to wanting to eat more food.

Sleeping less also leads to alzheimer’s and dementia. Brain needs the “sharp wave ripples” discovered by American and French researchers in 2009 in order to consolidate memory. Sharp wave ripples occur most frequently during the deepest levels of sleep occurring during longer sleep time frames.

Lack of sleep is directly linked to the weakening of your immune system. Missing sleep over time wears down your immune system, making it more difficult for your body to fight off viruses and diseases. Cytokines are proteins your body releases during sleep, which increase when you have an infection or inflammation, and sleep deprivation may decrease the production of these protective proteins. Effects of sleep deprivation on your immune system can be many, including slowing down your recovery if you do get sick and making you more likely to get sick after being exposed to a virus, such as the common cold.

Ageing becomes faster by lacking sleep. First notification is puffy, red eyes. If this continues over time, it leads to fine lines and wrinkles, hallow skin and dark circles under your eyes. During sleep your body repairs itself, strengthening bones and thickening your skin. Be kind to your skin by getting adequate rest on a regular basis.

Different people need different amounts of sleep, and this can be influenced by age, lifestyle, diet and environment. For example, newborn babies can sleep for 16 hours a day, while school-age children need an average of 10 hours sleep. Most healthy adults sleep for an average of seven to nine hours a night. As you get older, it is normal to need less sleep. Most people over 70 needs less than six hours sleep a night, and they tend to be light sleepers.

So take your stress reduction strategies seriously and get to sleep, darn it!
