What is the most important sleep?

All stages of sleep are important, but the deepest sleep, also known as slow-wave sleep (SWS) or deep sleep, is in some ways the most important. During deep sleep, body functions drop to their lowest level, including heart rate, blood pressure and breathing. It is also during this phase that most of the body's regeneration and repair takes place, as hormones are released that promote the growth and renewal of cells and tissues. The body's own defense system is also strengthened during this phase.

Deep sleep occurs in the first half of the night and decreases with increasing age. Therefore, it can become more difficult to get enough deep sleep the older you get. However, it is also important to emphasize that all sleep phases are important and work together to regenerate and repair, support memory and learning, and strengthen the body's immune system. It is therefore advisable to make sure you get enough sleep overall and maintain a healthy sleep rhythm.
