What is core sleep?

Core sleep refers to the essential period of deep, restorative sleep that the body needs to function properly. This type of sleep typically occurs during the first half of the night and is characterized by slow-wave sleep, which is the deepest stage of sleep where the body repairs and rejuvenates itself.

During core sleep, the body is able to reset its internal clock, regulate hormones, and consolidate memories. It is also believed to be important for overall health and well-being, as insufficient core sleep can lead to a range of health problems, including obesity, depression, and cognitive impairment.

It is recommended that adults get between 7-9 hours of core sleep per night to ensure optimal physical and mental functioning. Establishing a regular sleep schedule, creating a relaxing bedtime routine, and creating a comfortable sleep environment can all help to improve the quality of core sleep.
