Costs of poor quality/quantity of sleep
1. Major contributor to increased pain and decreased health. Backaches and joint pain are the most common pain symptom accompanying sleeplessness.
2. Increased dysfunction, weaker muscles, decreased energy and mood, and worsening of anxiety and depression. Depression has been linked to a lack of quality sleep (World Health Organisation)
4. Chronic Fatigue Immune Dysfunction Syndrome sleep is very important, not only for our day-to-day function, but also to recovery. (Benefits of quality, restful sleep) are improved cognition, mood, pain, immune and endocrine function
5. The effects of poor sleep cycles on our health is enormous, causing problems like weak immune systems, fatigue, brain fog, mood swings, anxiety attacks, irritability, blurred vision, nausea, decreased sex drive, memory lapses and eventually death.
6. Professor Phillipa Gander of NZ Sleep/Wake Centre said : We know experimentally that if you deprive
people of sleep, even only a few hours a night, you certainly change their waking function. They are sleepy. They tend to be more irritable. They are slowing progressively in terms of their reaction time, in terms of
their cognitive processing, in terms of their psychomotor coordination,”
7. A 2005 large study of a nationally representative sample of about 10,000 adults, suggested that the U.S.' obesity epidemic might have as one of its causes a corresponding decrease in quality and enough sleep. Some scientists speculate that this might be happening because sleep deprivation might be disrupting hormones that regulate appetite. One of the things that determines satiety (feeling full) is a thing called
'leptin' ", says our sleep specialist. "It's been shown that leptin levels are decreased where sleep is disrupted
8. Chronic sleep loss may speed the onset or increase the severity of age-related conditions such as type 2
diabetes, high blood pressure, obesity and memory loss (Wharton, 2003).
9. Department of Psychology, University of Rome, 'La Sapienza', Rome, Italy. Studied link between learning and memory and sleep. Their study found that 1) sleep quality and quantity are closely related to student learning capacity and academic performance; (2) sleep loss is frequently associated with poor declarative
and procedural learning in students; (3) studies in which sleep was actively restricted or optimized showed, respectively, a worsening and an improvement in neurocognitive and academic performance
People who experience sleep deprivation say it affects their overall health, their work life, their ability to pursue personal interests, and their relationships with family and friends.
