Waking up at 3 or 4 am may be caused by neurasthenia, improper diet, insufficient qi and blood, and disrupted biological clock. Here are the reasons:

Causes of Waking up at 3 or 4 am

1. Neurasthenia

People with neurasthenia generally have sleep disorders, such as insomnia and difficulty falling asleep. Even after falling asleep, they may suddenly wake up, especially in the middle of the night. It is difficult for them to fall asleep again after waking up.

2. Improper Diet

Improper diet before going to bed can also affect sleep quality. Eating too much or drinking stimulating beverages like coffee or tea before bedtime can easily lead to frequent waking up in the middle of the night, and even insomnia.

3. Insufficient Qi and Blood

If a person has insufficient qi and blood, they are also likely to wake up in the middle of the night and have difficulty falling asleep again. This is because various organs in our body need to transport blood. If there is insufficient qi and blood, it will lead to the inability to transport blood to various parts of the body in time, resulting in abnormal changes in the body. Therefore, it is easy to wake up at 3 or 4 am and have difficulty falling asleep again.

4. Disrupted Biological Clock

Many people have bad sleeping habits, such as staying up late and oversleeping in the morning. These bad habits can lead to a disrupted biological clock and greatly affect normal sleep quality, making it easy to wake up in the middle of the night.

Methods to Improve Sleep Quality

1. Regular Schedule

First, maintain a regular schedule in life. A regular rest time plays a significant role in improving sleep quality. If your current schedule is irregular, you should start to improve it. Although it may be difficult at the beginning, gradually adapting to a good biological clock will improve sleep quality.

2. Adjust Diet

Secondly, pay special attention to evening meals. Avoid eating too much or drinking stimulating beverages before bedtime. These bad eating habits can affect normal sleep quality and should be avoided as much as possible. It is recommended to eat less for dinner and keep it light.

3. Soak Feet Before Bed

Lastly, soaking feet in hot water before bedtime can promote blood circulation and help relax leg muscles, relieving tension in the body and effectively promoting sleep and improving sleep quality.
