Core sleep refers to a specific amount of uninterrupted rest that is crucial for optimal physical and cognitive functions. It typically encompasses deep sleep (non-rapid eye movement or NREM stage 3 and 4) and rapid eye movement (REM) sleep, the two most restorative stages of the sleep cycle.
Properly timed core sleep is important for a range of biological processes, including tissue repair and immune system strengthening. It also plays a vital role in cognitive functions such as memory consolidation and emotional regulation. During core sleep, the brain performs critical activities that support learning,情绪调节, and overall mental well-being.
Sleep specialists generally use the term core sleep as a reference to the minimum amount of sleep needed to function throughout the day. However, the amount of core sleep needed can vary depending on several factors, such as age, health status, and lifestyle. While some adults may need 6-8 hours of core sleep per night, individuals with insomnia or sleep apnea may require more.
Improving core sleep often involves creating a holistic bedtime routine that addresses lifestyle, environment, and habits to ensure better rest. This may include going to bed and waking up at the same time, creating a sleep-friendly environment, limiting exposure to screens before bedtime, practicing relaxation techniques before bed, and being mindful of dietary habits that can affect sleep.
It's essential to prioritize core sleep if you want to maintain an optimal quality of sleep and a balanced and rejuvenating sleep routine.
