"Work stress is the most common cause of sleep disturbance."
Research from Consumer Reports found that, among all people who report trouble sleeping, the most common cause for staying awake is work-related stress, followed by health and financial worries. The study, which surveyed 26,451 participants, found that 60% of respondents considered themselves insomniacs, 40% had tried over-the-counter sleep aids, and 30% had tried prescription medication-but about half of people using sleep medications reported some kind of side effect. Buying a new mattress helped 75% of respondents with their sleep problems.
