Poor sleep is also a risk factor for depression and substance abuse, especially among people with post-traumatic stress disorder, according to Anne Germain, associate professor of psychiatry at the University of Pittsburgh. People with PTSD tend to relive their trauma when they try to sleep, which keeps their brains in a heightened state of alertness.

The elderly are especially vulnerable. Timothy H. Monk, who directs the Human Chronobiology Research Program at Western Psychiatric, heads a five-year federally funded study of circadian rhythms, sleep strength, health articles about sleep, stress reactivity, brain function and genetics among the elderly.

The risks of cardiovascular diseases and stroke are higher in people who sleep less than six hours a night.

Even a single night of inadequate sleep can cause daylong elevations in blood pressure in people with hypertension. Inadequate sleep is also associated with calcification of coronary arteries and raised levels of inflammatory factors linked to heart disease.

In terms of cardiovascular disease, sleeping too much may also be risky. Higher rates of heart disease have been found among women who sleep more than nine hours nightly. The risk of cancer may also be elevated in people who fail to get enough sleep. A Japanese study of nearly 24, women ages 40 to 79 found that those who slept less than six hours a night were more likely to develop breast cancer than women who slept longer.

The increased risk may result from diminished secretion of the sleep health articles about sleep melatonin.

Children can also experience hormonal disruptions from inadequate sleep. Growth hormone is released during deep sleep; it not only stimulates growth in children, but also boosts muscle mass and repairs damaged cells and tissues in both children and adults. Vatsal G.

Some of the most insidious effects of too little sleep involve mental processes like learning, memory, judgment and problem-solving. During sleep, new learning and memory pathways become encoded in the brain, and adequate sleep is necessary for those pathways to work optimally. People who are well rested are better able to learn a task and more likely to remember what they learned. The cognitive decline that so often accompanies aging may in part result from chronically poor sleep.

With insufficient sleep, thinking slows, it is harder to focus and pay attention, and people are more likely to make poor decisions and take undue risks. As you might guess, these effects can be disastrous when operating a motor vehicle or dangerous machine.
