What is this?

Your asleep value (clinically referred to as total sleep time) reflects the total amount of time you were asleep during the night, including light, deep, and REM sleep. This value may be affected by your lifestyle, environment, and health.


Why is it important?

Getting enough sleep is essential to your body’s development and repair, as well as for memory consolidation. The amount of sleep you get therefore has a big impact on your health. Short-sleepers are more likely to gain weight, develop cardiovascular disease, type-2 diabetes, and even some forms of cancer.


Normative ranges

How much sleep you need depends on your age. The National Sleep Foundation gives the following guidelines per age group:

  • Teenagers (14-17 years): 8-10 hours
  • Younger adults (18-25 years): 7-9 hours
  • Adults (26-64 years): 7-9 hours
  • Older adults (65+ years): 7-8 hours
