About 50 to 70 million Americans have sleep or wakefulness disorders. Sleep deficiency and untreated sleep disorders are associated with a growing number of health problems, including heart disease, high blood pressure, stroke, diabetes, obesity, and certain cancers. Sleep disorders can also be costly. Each year sleep disorders, sleep deprivation, and sleepiness add to the national health care bill. Undiagnosed sleep apnea alone is estimated to cost the Nation $150 billion annually. Additional costs to society for related health problems, lost worker productivity, and accidents make sleep disorders a serious public health concern. The NHLBI funds research to discover better ways to promote and achieve sleep health, inform public policy, and increase community awareness to enhance human health.</p></div>

In 2016, the NHLBI released its Strategic Vision, which will guide the Institute’s research activities for the coming decade. Many of the objectives, compelling questions, and critical challenges identified in the plan focus on sleep. For example, researchers will be looking at whether changing the time of day (circadian rhythm) when one sleeps, eats, and takes medicines can help improve existing treatments for other diseases, such as high blood pressure, diabetes, and asthma. Training the next generation of sleep scientists is also a high priority for NHLBI.</p></div>
