Familial sleep traits are heritable variations in sleep patterns, resulting in abnormal sleep-wake times and/or abnormal sleep length.. Circadian rhythms are coordinated physiological and biological changes that oscillate on an approximately 24-hour cycle.
The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [1]
"This is problematic, as women are already at twice the risk of having insomnia compared to men." Sleep medicine physician Dr. William Lu, medical director at Dreem Health in San Francisco, said ...

Sleep research conducted in the 1990s showed that such waking up during the night may be a natural sleep pattern, rather than a form of insomnia. [2] If interrupted sleep (called "biphasic sleeping" or " bimodal sleep ") is perceived as normal and not referred to as "insomnia", less distress is caused and a return to sleep usually occurs after ...
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
Interrupted sleep is a primarily biphasic sleep pattern where two periods of nighttime sleep are punctuated by a period of wakefulness. Along with a nap in the day, it has been argued that this is the natural pattern of human sleep in long winter nights. [9] [10] A case has been made that maintaining such a sleep pattern may be important in ...
People in perimenopause who slept between 6-9 hours per night had an increase in their estrogen levels, which improved their sleep and lessened their symptoms, a new study has shown.
