Samsung scans 716 million nights: Sleep is declining everywhere and for everyone،
Analyzing data from as many as 716 million nights, Samsung is conducting one of the largest sleep health studies ever undertaken. The goal is to answer the question: “Did we sleep well?” »
It turns out the answer is “No!” » – and things are getting worse everywhere and for everyone, according to the data (via SamMobile).
The report of Samsung analyzes 716 million nights of sleep behaviors of Samsung Health and Galaxy Watch users worldwide. “Even though interest in personal sleep health has skyrocketed, the sad reality is that the quality of sleep people get each night is actually in decline. The world faces a sleep dilemma,” says Samsung.
Data is collected between June 2021 and May 2023. The number of users actively tracking their sleep has increased by 182% over the past two years, but sleep efficiency and quality are declining everywhere and for everyone. Samsung compares two periods: June 2021-May 2022 and June 2022-May 2023.
Samsung found that average sleep duration decreased globally, from 7 hours and 3 minutes to 6 hours and 59 minutes, which is just below the 7 hour threshold recommended by the National Sleep Foundation.
And as sleep duration decreased, wake times during sleep increased, ultimately leading to a decrease in sleep efficiency – a ratio of actual sleep time to total time spent in bed each night.
This trend is not isolated to any specific demographic or region. Decreased sleep duration and efficiency were reported in all genders, age groups and regions studied. Here are some key points:
- Although sleep efficiency continues to decline among men, it is women who have experienced the most notable declines over the past year.
- Older demographics showed a greater decline in sleep efficiency. Notably, people aged over 70 experienced a decline almost twice as large as that seen among people in their 20s.
- North America experienced the greatest decline in sleep efficiency, while Asia maintained the lowest.
- Outside of Europe and North America, all other regions had less than seven hours of sleep.
