What is core sleep
Core sleep refers to the deep, restorative sleep that occurs during the night, typically during the slow-wave sleep (SWS) stage. It is characterized by slow brain waves, low body temperature, and a decrease in blood pressure. Core sleep is essential for physical and mental restoration, as it allows the body to repair and regenerate tissues, build bone and muscle, and strengthen the immune system.
During core sleep, the body also clears out toxins and waste products from the brain, consolidates memories, and processes emotional experiences. This stage of sleep is critical for overall health and well-being, and research suggests that most adults need 7-9 hours of core sleep each night to feel rested and alert.
Some of the benefits of core sleep include:
Improved cognitive function and concentration
Enhanced athletic performance and physical recovery
Boosted immune system function
Better management of stress and emotions
Improved glucose regulation and weight management
Reduced risk of chronic diseases, such as heart disease and diabetes
To improve core sleep, it is recommended to establish a consistent sleep schedule, create a relaxing bedtime routine, and create a sleep-conducive environment. Avoiding caffeine, nicotine, and electronic screens before bedtime can also help promote core sleep.
Recommended products or services to improve core sleep include:
- White noise machines or earplugs to create a quiet sleep environment
- Sleep masks or blackout curtains to block out light
- Comfortable and supportive pillows and mattresses
- Relaxing essential oils, such as lavender or chamomile
- Guided meditation or sleep apps, such as Calm or Headspace
- Sleep trackers or smartwatches to monitor sleep quality and duration.
