Sleep Stages and Their Characteristics

Did you know that you go through four different sleep stages while sleeping?

At night, while you recharge your energy for the new day, you go through (or rather, sleep through) four to seven sleep cycles, each consisting of four sleep stages. The four stages are: the falling asleep phase, the light sleep phase, the deep sleep phase, and the dream sleep phase. We will now explain what happens in the different phases:

1. Falling Asleep Phase

The name of this phase speaks for itself. This is the first phase you reach when you go to bed in the evening to comfortably start your night's sleep. It describes the moment when we move between wakefulness and sleep and usually only lasts a few minutes. During the falling asleep phase, the body slowly calms down, and breathing and pulse become steadier. However, sleep is still very light; you are still very sensitive to noise, and muscle relaxation can lead to muscle twitching – which can resemble the feeling of (pleasant) falling.

2. Light Sleep Phase

The falling asleep phase is followed by the light sleep phase, which makes up the largest part of the total sleep time. In this phase, actual sleep begins, but one is still not truly deeply asleep. In the light sleep phase, one is still susceptible to noise or light and wakes up quickly if changes in the surroundings are perceived. Muscle tension continues to decrease in this sleep stage, and eye movements behind closed eyelids are barely perceptible. The heart rate also slows down further, body temperature drops slightly, and brain activity slows down.

3. Deep Sleep Phase

The third sleep phase – the deep sleep phase – is where the body regenerates the most. In this deep sleep phase, muscles are relaxed, blood supply to the muscles increases, and there is an increased release of growth hormones. The body works intensively on strengthening the immune system during this phase. In the deep sleep phase, it is significantly harder to wake up than in the previous phases, and if one wakes up abruptly, one usually feels very groggy and disoriented.

4. Dream Sleep Phase (also called REM Sleep Phase)

The dream sleep phase, also known as the REM sleep phase (REM stands for Rapid Eye Movement), is characterized by rapid, perceptible eye movements behind closed eyelids and intense dreams. Although the muscles are largely relaxed, brain activity during REM sleep is similar to that in the waking state. This phase is crucial for cognitive function, learning processes, and emotional balance. REM sleep increases with each sleep cycle and reaches its longest duration in the last cycle. In the REM sleep phase, our breathing rate increases again, breaths become deeper, and our blood pressure and heart rate rise. At the end of the sleep period, we either wake up from REM sleep because the night is ending and the day is dawning, or we glide back into a new sleep cycle.

Balanced sleep that goes through all four phases is crucial for recovery and maintaining physical and mental health. Sleep disturbances or interruptions in this cycle can lead to fatigue and reduced performance. Therefore, it is not only important to get enough sleep but also to ensure that all sleep phases are completed to achieve the best results for health and well-being.

While we cannot influence when and for how long you sleep each day, we can do our best to make your bed a haven of well-being to support you in getting a good night's sleep.
