In an interview with New York magazine's blog The Cut, trainer-to-the-stars Anna Kaiser said everyone should sleep at least 7 to 8 hours a night and that getting by on just 5 or 6 hours a night is not healthy.

Kaiser, who counts Karlie Kloss, Shakira, Kelly Ripa, and Sarah Jessica Parker among her clients, stressed sleep (and, of course, water. Are you drinking water? Go get some water) as one of the most essential ingredients in a balanced life.
