makaamisjaksoissa

makaamisjaksoissa is the Finnish term for the sleep cycles that occur during a typical night of sleep. It refers to the repeated oscillations between non‑rapid eye movement (NREM) and rapid eye movement (REM) stages that together constitute a full sleep episode. A single sleep cycle lasts roughly 90 to 110 minutes and most adults experience between four and six cycles per night.

The stages of a typical cycle are first and second stage NREM (light sleep), followed by NREM stage three or four (slow‑wave or deep sleep), and concluding with a period of REM sleep during which brain activity resembles wakefulness but muscles are generally paralyzed. The proportion of time spent in each stage changes across the night: deep sleep predominates in the first two cycles, while REM duration grows with each successive cycle. Adequate amounts of both NREM and REM are essential for restoring physical health, consolidating memories, and regulating mood.

Sleep cycles are measured through polysomnography, a composite recording that captures electroencephalography, eye movements, muscle tone, heart rate, and breathing patterns. Clinicians use this data to diagnose sleep disorders such as insomnia, sleep apnea, and narcolepsy. Disruptions to normal cycle length or stage distribution can lead to fragmented sleep and daytime sleepiness.

Research on makaamisjaksoissa also informs public health guidance. Consistent sleep timing, avoidance of late‑night screens, and proper sleep hygiene are recommended strategies to preserve the natural architecture of sleep cycles. Studies indicate that maintaining regular cycles improves cognitive performance, metabolic regulation, and overall well‑being.
