Waking every three hours, tossing and turning, and being chronically tired are more common than most people think. In fact, more than one-third of American adults do not get enough sleep. Their insomnia not only hurts their productivity, it also hurts their heart and can increase their risk of stroke, particularly for young adults.
A new study from Taiwan shows that insomnia raises the likelihood of being hospitalized due to stroke by 54 percent. That risk grew exponentially for people ages 18 to 34, who were eight times more likely to have a stroke than peers who got adequate sleep.
