Poor sleep inevitably leads to weight gain. Full video link:    • 熬夜越胖越憂鬱，睡眠不足等於代謝崩壞，睡不好必胖   The importance of sleep for health and weight loss is widely recognized. Insufficient sleep or staying up late negatively impacts hormone secretion, leading to a decreased metabolic rate, increased appetite, and making it easier to gain weight. I will analyze the importance of sleep for weight loss and detail the physiological mechanisms of sleep, the circadian rhythm of hormones, and the effects of disrupted day-night cycles on the body. Sleep is a crucial process for the body's recovery and repair. When we sleep, the body enters a stage called non-rapid eye movement (NREM) sleep. This stage of sleep is essential for repairing body tissues, strengthening the immune system, and regulating hormone secretion. Especially during deep sleep, the body releases growth hormone, which is crucial for promoting fat metabolism and maintaining muscle mass. If we divide the sleep cycle into four stages, non-rapid eye movement (NREM) sleep can be further subdivided into N1, N2, N3, and REM sleep stages. This classification provides a more detailed description of sleep variations and characteristics. Here's an explanation of dividing the sleep cycle into four stages: N1 Stage: This is the initial stage of falling asleep, where people feel relaxed and lightly sleepy. In N1, our brainwave activity begins to slow down and become irregular, and some hallucinations or auditory hallucinations may occur with eyes closed. This stage typically accounts for a small portion of the total sleep time. N2 Stage: This is the main part of sleep, accounting for the majority of the total sleep time. In N2, brainwaves become more stable, and characteristic waveforms called sleep rhythms appear. In addition, eye movements cease, muscle activity decreases, and the body enters a deeper state of rest. N3 Stage: This is the deep sleep stage, also known as slow-wave sleep (SWS). During this stage, brain waves show a large amount of slow-wave activity, also known as delta waves. Deep sleep is crucial for the body's repair and recovery, helping to promote immune function, tissue repair, and the release of growth hormone. Rapid Eye Movement (REM) Stage: This is REM sleep, and one of the important stages in the sleep cycle. During REM sleep, our eyes move rapidly, and brain activity is similar to that of the waking state. This stage usually occurs about 90 minutes after falling asleep and repeats in the morning portion of each sleep cycle. REM sleep is very important for the development of memory and learning abilities and is also related to dream generation. Dividing the sleep cycle into four stages provides a clearer understanding of the characteristics and functions of different sleep stages. The proportion and order of each stage in the entire sleep cycle may vary. The number of sleep cycles in a night varies from person to person, but it is generally recommended to have about four to five complete sleep cycles to ensure sufficient and high-quality sleep. Each complete sleep cycle lasts approximately 90 to 120 minutes and includes both non-REM and REM sleep stages. The number of sleep cycles depends on individual sleep needs and habits. Generally, adults should get about 7 to 9 hours of sleep per night, which includes multiple sleep cycles. Therefore, assuming each sleep cycle is 90 minutes, we expect to experience about five complete sleep cycles in a night. Maintaining a regular sleep cycle is crucial for physical and brain health. It helps regulate hormone secretion, restore energy, promote memory and learning abilities, and provide the body with the necessary repair and recovery time. However, it's important to note that some people may have different sleep needs and cycles. Some people may only need shorter sleep durations, while others require longer sleep to feel fully rested. Everyone's physiological and psychological state is unique, therefore the ideal number of sleep cycle cycles will vary. Most importantly, it's essential to maintain good sleep habits, including consistent bedtimes and wake-up times, creating a sleep-friendly environment, and avoiding staying up late and excessive use of electronic devices. By maintaining good sleep quality and proper sleep cycles, we can improve physical and brain function, and achieve better health and quality of life. Staying up late or lack of sleep disrupts this normal physiological mechanism. Staying up late often prevents people from getting enough deep sleep, which reduces the release of growth hormone, and negatively impacts the body's metabolism. Studies show that lack of sleep re...
