Digital Trends recently profiled SHUTi, an online program for people who suffer from insomnia.

Recent research suggests the SHUTi course is also effective. In a sample of 303 adults with chronic insomnia, those who took nine weeks of SHUTi showed significant improvement in their insomnia symptoms compared to those who did not use it. Many of the patients maintained their improved sleep patterns over time, with roughly 57 percent receiving the classification of “insomnia remitter” after one year.

If the results hold up, the program could help a lot of people. JAMA indicates that 20 percent of adults meet the diagnostic criteria for insomnia, while 50 percent of adults report occasional insomnia symptoms. Per the CDC, school age children should get at least 10 hours of sleep per night, teens roughly nine to 10 hours, and adults seven to eight hours. The Centers for Disease Control say insufficient sleep is increasingly recognized as a public health problem.
