What to do before bed to get a better night's sleep
In the modern fast-paced life, good sleep quality is essential to maintain good health and improve quality of life. Sleep is often divided into different stages, with core sleep and deep sleep considered to be the two most critical phases. This article will delve into the importance of core sleep and deep sleep and try to find a balance between them.
Part I: The Importance of Core Sleep
Core sleep refers to the first half of the sleep cycle, which mainly consists of light sleep and rapid eye movement (REM) sleep stages. This stage is crucial for learning, memory, emotional regulation, and physical recovery. Studies have shown that core sleep helps consolidate what is learned during the day and improves cognitive function and creativity.
1.1 The key to learning memory
Core sleep is a critical period for the brain to organize and process information. At this stage, the brain consolidates and reinforces the information we learn during the day by strengthening the connections between neurons. Insufficient core sleep can lead to memory loss and poor learning.
1.2 Support for emotional regulation
A good core sleep helps maintain emotional balance. Studies have found that a lack of adequate core sleep can lead to mood swings and an increased risk of anxiety and depression. Therefore, maintaining healthy core sleep is essential for mental health.
1.3 The moment of physical recovery
Core sleep also provides the body with ample recovery time. During this phase, the body releases growth hormone, which promotes cell repair and metabolism. In addition, the immune system is also strengthened during core sleep, which helps to improve the body's resistance.
Part II: The Value of Deep Sleep
Deep sleep, the second half of the sleep cycle, consists mainly of slow-wave sleep (SWS) and non-rapid eye movement (NREM) sleep. This stage is essential for the repair of the body and the regulation of physiological functions.
2.1 Regulation of physiological functions
Deep sleep is a critical period for the body to undergo physiological repair. During this phase, the body releases growth hormone, which promotes the growth of tissues and bones while maintaining the normal function of organs. Deep sleep also helps regulate blood pressure, heart rate, and blood sugar levels.
2.2 Reinforcement of the immune system
Deep sleep is essential for the proper functioning of the immune system. During this phase, immune cells become active, strengthening the body's resistance to viruses and bacteria. As a result, lack of deep sleep can lead to a weakened immune system and an increased risk of illness.
2.3 Maintenance of emotional and mental health
Deep sleep also has a positive impact on mood and mental health. Getting enough deep sleep can help reduce stress and anxiety and improve emotional stability. In addition, deep sleep is inversely associated with the incidence of depression and other mental health problems.
Part III: Balancing Core Sleep with Deep Sleep
Although core sleep and deep sleep each have their own unique importance, there is a close relationship between them. Good core sleep provides the brain with sufficient energy and wakefulness, making it easier to fall into deep sleep. Conversely, the quality and duration of deep sleep is also affected by core sleep.
3.1 Cycles reinforce each other
Core sleep and deep sleep are mutually reinforcing through cycles. Throughout the sleep cycle, core sleep and deep sleep alternate and work together to maintain the health of the body and brain. This balance of cycles is key to maintaining overall sleep quality.
3.2 Influence of external factors
The external environment and the individual's lifestyle also have an impact on the balance between core sleep and deep sleep. Proper sleep conditions, regular sleep schedules, and healthy lifestyle habits all contribute to maintaining this balance. Conversely, excessive stress, tension, and poor sleep habits can disrupt the normal cycle of core sleep and deep sleep.
Conclusion:
In the battle between core sleep and deep sleep, we should focus more on finding a balance between them. Good core sleep provides wakefulness to the brain, while deep sleep provides the body with a chance to repair and recharge. It is only when both phases are fully fulfilled that we can truly experience comprehensive physical and mental health.
