Have We Been Sleeping Well? Samsung Answers the Age-Old Question With the Global Sleep Health Study – Samsung Global Newsroom | Laptop News

Today, more and more are prioritizing sleep as it relates to health.

This pattern was not isolated to any specific demographic or region. There was a reported decrease in sleep duration and efficiency across all sexes, age groups, and regions studied:

• Though sleep efficiency continues to trend downward for males, females experienced the most notable decreases over the past year. (Chart 2)
• Older demographics showed a greater decline in sleep efficiency. Notably, individuals aged over 70…
