Darauf folgt der Tiefschlaf. 2 Bei Erwachsenen dauert so ein Schlafzyklus etwa 90 Minuten und besteht aus Leichtschlaf-, Tiefschlaf-, REM- („rapid eye movement“, „Traumphasen“). 3 Die Muskulatur ist während der REM-Phase ruhig, das Gehirn hingegen sehr aktiv. In dieser Phase erholt sich der Mensch und träumt. Je nachdem. 4 Newborn babies spend roughly 50% of their time asleep in REM. Since newborns sleep up to 18 hours each hour period, that means they experience up to nine hours of REM each day. As a baby’s sleep schedule changes, so do their sleep cycles. Baby REM sleep is one part of the sleep cycle that changes over time. 5 There are two types of sleep: REM (rapid eye movement sleep). This is a light sleep when dreams occur and the eyes move rapidly back and forth. Although babies spend about 16 hours each day sleeping, about half of this is in REM sleep. Older children and adults sleep fewer hours and spend much less time in REM sleep. 6 Breathing is often irregular and may stop for 5 to 10 seconds—a condition called normal periodic breathing of infancy —then start again with a burst of rapid breathing at the rate of 50 to 60 breaths a minute for 10 to 15 seconds, followed by regular breathing until the cycle repeats itself. 7 It’s estimated that newborns spend about 40%% of their sleep in REM. That translates to, on average, hours per day in REM. As we age, REM sleep lessens. Children spend about 25%% of their sleep in REM, and adults spend 15%% of their sleep in this stage. 8 At about six to eight weeks,your baby is settling into a routine and may show signs of drowsiness to signal when it’s time for a nap. Your baby's sleep pattern may change—he may now fall asleep around 6 or 8 PM, with his longest period of evening sleep being about three to five hours long. 9 Once a baby reaches around three months of age, they begin experiencing the same sleep stages that adults experience. Adults experience four distinct sleep stages. These sleep stages include three stages of NREM sleep and one REM sleep stage. They are distinguished by the following brain waves. rem-phase baby offene augen 10
