Nightly Sleep Requirements for Adult Females
Adult females require 7-9 hours of sleep per night for optimal health and functioning 1.
- The optimal sleep duration for adults, including females, is 7-9 hours per 24-hour period, as stated by the American Thoracic Society 1.
- Individual variability exists, but sleeping less than 6 hours per night is associated with adverse outcomes, including mortality, while sleeping more than 9-10 hours per night may also be associated with adverse health outcomes 1.
- It is essential for adult females to prioritize sleep and aim for the recommended 7-9 hours of sleep each night to maintain good health and overall quality of life 1.
- Sleep disorders are common and can cause significant morbidity, but are treatable, and healthcare providers should be aware of the importance of sleep to health and the evaluation and management of common sleep disorders 1.
From the Research
Nightly Sleep Requirements for Adult Females
- The recommended sleep duration for adult females is 7-9 hours per night, as suggested by the National Sleep Foundation 2.
- A study analyzing data from over 11 million nights of objective in-home sleep data found that female participants had significantly longer sleep durations than male participants, but the exact sleep duration for adult females was not specified 3.
- Other studies have also suggested that adults, including females, should aim for 7-9 hours of sleep per night for optimal health and function 4, 5, 6.
- It is worth noting that individual sleep needs can vary, and some people may need more or less sleep than the recommended range 2.
- The prevalence of healthy sleep duration (≥ 7 hours) among adult females is not specifically reported in the provided studies, but one study found that 65.2% of adult respondents reported a healthy sleep duration, with lower prevalence among certain racial and ethnic groups 6.
