Sleep study explains why you may feel always tired

A Mattress Firm State of Sleep survey of 2,000 U.S. adults found average nightly sleep of 6.6 hours versus a reported ideal of 7.1 hours, and the report links persistent tiredness to sleep habits and bedroom environment.

Mattress Firm published a State of Sleep survey that examined how Americans sleep and why many still feel tired. The poll, conducted by Talker Research, involved 2,000 adults in the United States. It measured reported sleep duration, nightly experiences, and common habits around bedtime. The report highlights differences between what people know supports sleep and the sleep they actually get. Key findings: - The survey sampled 2,000 U.S. adults and was conducted by Talker Research for Mattress Firm. - Respondents reported an average of 6.6 hours of sleep per night, compared with 7.1 hours they said would be ideal. - In a typical month participants reported about 10 "perfect" nights of sleep and eight "bad" nights. - Fewer than 11% said they can properly adjust to less sleep; 48% said they can predict whether they will sleep well before going to bed; 15% said naps interfere with nighttime sleep. - Approximately 75% of participants used phones or watched TV before bed, and 81% said music or podcasts help them fall asleep. - The survey reported an average preferred sleep temperature of 66.3 degrees, and Mattress Firm representatives noted the bedroom environment and sleep system elements affect sleep quality. Summary: The survey points to sleep hygiene and bedroom conditions as contributors to persistent tiredness among U.S. adults. It documents gaps between people's knowledge of helpful sleep practices and the sleep they actually receive. Undetermined at this time.
