The “first night effect” (FNE) is a well-known phenomenon in polysomnographic (PSG) recordings characterized by decreased total sleep time, lower sleep efficiencies, reduction in REM sleep, and longer REM latencies on the first night of testing (Agnew, Webb, & Williams,1966).

The best time to sleep is at night, roughly between midnight and 7 a.m. Although exact sleep-wake times can vary from person to person, humans generally evolved to be active during the day.

Why do some marine mammals and birds show unihemispheric sleep?
Some animals show a different sleep behavior because sleep is induced in only one hemisphere, while the other hemisphere remains awake or it is awakened, termed as unihemispheric sleep. In some aquatic mammals, sleep and wakefulness periods alternate between the hemispheres, and it is the only way of sleeping.
