I've always had a lingering question about sleep. Don't our bodies' internal organs operate without a sense of time? So, why do people say that 11pm-1am is the time for liver metabolism? Why do people advocate for going to bed early and rising early, but not for sleeping in late and rising late? These questions swirled in my head until I started delving into the secrets of sleep. First, we need to understand how our bodies' internal clocks work. Our bodies have an internal clock system that regulates our metabolism, body temperature, hormone secretion, and other physiological activities. This clock system is influenced by external factors like sunlight, darkness, diet, and exercise, forming our usual day-night rhythm. So, why is 11pm-1am considered the time for liver metabolism? It turns out that the liver is our body's detoxifying organ, responsible for removing toxins and metabolic waste. During this time period, the liver's metabolic activity reaches its peak, helping us eliminate the toxins and fatigue accumulated during the day. Going to bed early allows us to make the most of this time period, increasing the liver's metabolic efficiency, and waking up feeling refreshed and revitalized. But which is more important, sleep duration or sleep schedule? The answer is both. Sleep duration affects our physical recovery and repair, while sleep schedule affects our internal clock and metabolism. Going to bed early and rising early helps us establish a healthy day-night rhythm, improving sleep quality and physical recovery. Therefore, sleeping in late and rising late is not a good choice. Although occasionally sleeping in might not have a significant impact on our bodies, doing so long-term will disrupt our internal clocks, leading to decreased sleep quality, weakened physical recovery, and even affecting our mood and cognitive function.
