losing that hour of sleep can have surprisingly serious health consequences

losing that hour of sleep can have surprisingly serious health consequences. Some experts raise concerns that changing the clocks can disrupt sleep patterns, and it's even been shown to put people at an increased short-term risk for heart attacks. A study released last year found that the number of heart attacks jumped 25 percent the day after the spring time change, perhaps because sleep loss puts increased strain on people already at risk. The number of cases returned to average later in the week. "This comes down to two things: number one, stress, and number two, sleep deprivation," said CBS News medical contributor Dr. Holly Phillips. "When we are sleep deprived or stressed, there are more inflammatory markers in our bloodstream, and that inflammation raises our risk of heart attacks." Even though a one-hour time change doesn't sound like much, she says it can be a big adjustment for the body's circadian rhythm. http://www.cbsnews.com/news/simple-tips-to-help-you-spring-forward-smoothly-daylight-saving-time/
