Do you know what scientific sleep is? Scientific sleep is a method based on research on human sleep cycles and quality. Scientific sleep can help improve your health, enhance memory, creativity, and work efficiency. Read this article by Mytour Blog to learn more about scientific sleep and how to apply it to your life.
Why is Scientific Sleep Necessary?
Why is scientific sleep necessary? This is a question that many people are concerned about because sleep is an essential activity for human health and quality of life. So what is scientific sleep?
The Benefits of Scientific Sleep
- Scientific sleep not only helps you have a good night's sleep but also enhances memory and learning ability. Did you know that when you sleep, your brain is actively processing and storing information learned during the day? As a result, you will find it easier to remember and be more creative when you wake up.
- This is also an effective way to protect your cardiovascular health. While you sleep, your blood pressure and heart rate naturally decrease, reducing stress on the heart. This helps prevent dangerous cardiovascular diseases such as stroke and heart attacks.
- Scientific sleep also strengthens the body's immune system. While you sleep, your body produces antibodies and immune cells to fight bacteria, viruses, and pathogens. As a result, you are less likely to get sick and are healthier.
- Improving sleep quality also affects your weight. While you sleep, your body regulates two important hormones, leptin and ghrelin, related to hunger and satiety. If you get enough sleep, these hormones will be balanced, helping you control food intake and avoid obesity. Conversely, if you lack sleep, these hormones will be disrupted, causing you to eat more and gain weight.
- Scientific sleep is also one of the key factors in improving your mood and vitality. While you sleep, your body releases happiness hormones like serotonin, dopamine, and endorphins. These hormones help reduce stress, depression, and boost energy for the new day.

Discovering Fascinating Facts About Scientific Sleep
An Overview of Scientific Sleep Cycles
Sleep is essential for human health and quality of life. However, not everyone knows that sleep is not a monotonous state but a complex process with various stages and cycles. To have a scientific sleep, we need to understand the structure and significance of sleep cycles.
According to researchers, sleep is divided into two main types: non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. Each type of sleep consists of several different stages, forming a sleep cycle. A sleep cycle typically lasts from 90 to 110 minutes, and in one night, we usually experience 4 to 6 sleep cycles.
NREM Sleep occupies about 75% of our sleep time and consists of 4 stages:
- Stage 1: This is the sleep onset stage, where the body begins to relax. This stage lasts only 5 to 10 minutes, and if awakened, we may not realize we were asleep. During this stage, brain activity decreases by about 50%, and heart rate and breathing also slow down.
- Stage 2: This is the light sleep stage, where the body enters a deeper sleep. This stage occupies about 50% of our sleep time. Brain activity continues to decrease, and body temperature and blood pressure decrease. This stage plays a crucial role in enhancing learning and memory.
- Stage 3: The deep sleep stage when the body undergoes tissue repair and recovery processes. This stage occupies about 10% of our sleep time. During this stage, blood pressure, heart rate, respiration, and body temperature decrease to their lowest levels. This stage is essential for boosting health and immunity.
- Stage 4: You will sleep very deeply, and the body enters a state of maximum rest. This stage occupies about 15% of our sleep time. Brain activity decreases to its lowest level, and it's very difficult to awaken. This stage is crucial for growth in height and weight.
REM Sleep occupies about 25% of our sleep time, with only one stage:
- Stage 5: This is the dream sleep stage, where the body is completely paralyzed but the brain is highly active. This stage occupies about 20% of our sleep time. During this stage, our eyes will move rapidly in different directions, and we will experience vivid dreams. This stage plays a crucial role in enhancing creativity and processing emotions.
Sleep cycles occur sequentially from stage 1 to stage 5 and then return from stage 5 to stage 2, continuing like this until waking up. Typically, the first sleep cycle will have more NREM sleep stages, while the last sleep cycle will have more REM sleep stages.
To achieve scientific sleep, we need to go to bed and wake up at the same time every day to establish a stable biological rhythm. Additionally, we also need to get enough quantity and quality of sleep cycles to meet the physiological and psychological needs of the body.

Sleep is crucial for human health and productivity. However, not everyone knows how to calculate the optimal sleep time to achieve the best quality rest. Mytour will introduce you to some simple and effective methods for determining the ideal sleep duration for yourself.
Method 1: Based on Sleep Cycles
Sleep cycles are units of time during which the body goes through various stages of sleep, from light sleep to deep sleep and dreaming. Each sleep cycle lasts about 90 minutes, and the body needs at least 4-6 sleep cycles per night to fully recover. Therefore, you can calculate the scientifically optimal sleep time by multiplying the desired number of sleep cycles by 90 minutes and adding 15 minutes to include the time to fall asleep. For example, if you want to have 5 sleep cycles, you should sleep for about 7.5 hours (5 x 90 + 15).
Method 2: Based on Wake-Up Time
The time you wake up also impacts the quality of your sleep. If you wake up during deep sleep or REM sleep stages, you'll feel tired, groggy, and have difficulty concentrating. Therefore, choose a wake-up time that aligns with your sleep cycles. You can use online tools like Sleep Calculator to determine ideal time frames for going to bed or waking up. For example, if you want to wake up at 6 AM, you should go to bed around one of the following times: 9 PM, 10:30 PM, 12 AM, or 1:30 AM.
Method 3: Based on Personal Needs
Each person has different sleep needs and habits. Some people only need 6 hours of sleep to feel rested, while others require up to 9 hours for comfort. Therefore, listen to your body and find the most suitable sleep time for yourself. You can track and record information about your sleep, such as bedtime, wake-up time, energy levels, and mood throughout the day for analysis and adjustment. You can also use sleep tracking apps or devices like Sleep Cycle or Fitbit to get detailed and accurate feedback on your sleep.
Practicing Scientific Sleep Timing to Adjust Circadian Rhythm (Source: Internet)Principles of Scientific Sleep
So how do you achieve scientific sleep? Some basic principles for a scientific sleep are as follows:
- Go to bed and wake up at the same time every day to establish a stable biological rhythm.
- Sleep for 7-8 hours each night to ensure your body rests and recovers.
- Avoid bright light, noise, and high temperatures before bedtime to create a quiet and comfortable environment.
- Avoid consuming caffeine, alcohol, and tobacco before bedtime to avoid affecting sleep quality.
- Engage in relaxing activities such as reading, listening to music, or meditation before bedtime to reduce stress and ease into sleep.
