A new study led by an Indian origin researcher has found that Indians sleep lesser as compared to white, American-born adults. Two studies have reported sleep disparities among Americans based on racial and ethnic background. The first study, out of the State University of New York (SUNY), looked at 400,000 respondents from the National Health Interview Surveys between 2004 and 2010. Results show that Americans born in the United States were more likely to report sleeping longer than the recommended seven to nine hours each night. African-born Americans were more likely to report sleeping six hours or less, and Indian-born Americans reported six to eight hours a night.
