A common observation in our daily lives is that some people sleep only five or six hours a night and are still energized the next day, while others need up to eight hours or more of sleep to rejuvenate. This phenomenon has sparked a lot of curiosity and discussion: why do people who sleep for shorter periods seem to be more energetic than those who get enough sleep?
As a senior doctor, I have encountered many patients who are confused about sleep problems in my daily work. They often ask if their sleep patterns are not normal or if they need to take somemeasures to increase sleep time. This article aims to delve into the relationship between sleep time and energy, revealing the science behind itand provide some practical tips to help you improve your sleep quality and improve your energy levels in your daily life.
Sleep is not only a process of rest, but also a critical moment for the body and brain to repair and strengthen themselves. Everyone's sleep cycle consists of multiple phases, from light sleep to deep sleep to REM (rapid eye movement) sleep, each of which is essential for good health. During the deep sleep phase, the body undergoes tissue repair, immunity boosting, and energy recovery, and REM sleep is essential for brain function, especially the maintenance of memory and learning.
Studies have shown that people with high sleep quality are able to complete these important physiological processes more efficiently. Sleep duration, on the other hand, is not always a direct indicator of sleep quality. Some people, even if they sleep for a shorter period of time, may have their bodies and brains recover more efficiently if they can quickly enter the deep sleep stage than those who sleep longer but sleep lightly.
Short sleepers are often misunderstood, and people think that they are synonymous with stress, irregular lifestyles. However, studies have found that some people in this group are genetically able to recover with shorter sleep durations。This phenomenon, sometimes referred to as the "short sleep gene," means that individuals can feel well rested after 6 hours or less of sleep.
The potential benefits of short sleepers are not limited to genetics. They tend to be more focused on the quality of their sleep and take steps to ensure that every minute of sleep is as productive as possible. For example, they may have a more rigorous bedtime routine, avoid electronic devices, reduce caffeine intake, and create an environment that promotes deep rest. In addition, short sleepers may be more focused on rest and stress-relieving methods during daytime activities, such as short meditations or naps, which can help them stay energized.
This series of habits and strategies for short-sleepers not only explains why they can stay active in shorter sleep periods, but also provides a reference for long-term sleepers to improve their sleep quality. It is important to recognize,Whether it's a short or long sleep, it's crucial to find a sleep pattern that works for you and take steps to ensure quality sleep so you can be at your best, both physically and mentally.
When exploring the relationship between sleep and health, we often come across a common misconception that the more sleep you get, the better. However, studies have shown that excessive sleep duration (usually more than 9 hours per night) may not be a sign of physical health, but is associated with health problems such as abnormal glucose metabolism and increased blood pressure in systemic arteries.
Sleeping too much is also a problem?
Prolonged sleep can lead to a decrease in the body's metabolic rate, affecting hormone levels, which in turn may increase the risk of body weight, cardiovascular disease, and abnormal glucose metabolism. Additionally, excessive sleep can be an underlying health problemA signal, not a cause.
Quality is not quantity, the key is balance
