I don't feel sleepy at night and want to sleep during the day

Circadian rhythm disorders are a common cause of feeling sleepy at night and wanting to sleep during the day. They are mainly related to biological clock imbalance, psychological stress, bad sleep habits, environmental factors and underlying diseases.

1. Biological clock imbalance:

The human body's internal biological clock is affected by light. Staying up late or working shifts for a long time will disrupt the melatonin secretion cycle. Melatonin is an important hormone that regulates sleep, and its peak secretion is usually at night. The blue light produced by frequent use of electronic devices suppresses melatonin secretion, making it difficult to fall asleep. Adjusting your work and rest time and fixing your wake-up time can help reestablish your biological clock rhythm.

2. Psychological pressure:

Emotional problems such as anxiety and depression activate the sympathetic nervous system and put the brain on alert. Continuous psychological stress can lead to abnormal cortisol levels and affect the quality of deep sleep. Being in a high-pressure state for a long time may cause delayed sleep phase, manifested as being awake at night and sleepy during the day. Mindfulness meditation and psychological counseling can effectively alleviate the impact of emotional factors on sleep.

3. Bad sleeping habits:

Ingesting caffeine or nicotine before bed can stimulate the central nervous system, and taking a nap for too long can reduce the drive to sleep at night. Irregular work and rest times will disrupt the sleep-wake cycle and form a vicious cycle. Establishing a fixed bedtime ritual such as taking a warm bath, reading paper books, and avoiding strenuous exercise before bedtime can help develop good sleep habits.

4. Environmental factors:

Excessive light, noise interference, and temperature discomfort in the bedroom will all affect sleep quality. The blue light emitted by electronic devices can interfere with melatonin secretion. It is recommended to stop using electronic devices one hour before going to bed. Using blackout curtains, white noise machines, and keeping the room temperature at 18-22 degrees Celsius can improve the sleeping environment.

5. Potential diseases:

Sleep apnea causes frequent awakenings during the night, and abnormal thyroid function may cause drowsiness symptoms. Restless legs syndrome can affect falling asleep, and depression is often accompanied by early waking problems. These diseases require professional doctors to diagnose them through polysomnography and other examinations. Targeted treatment of the underlying disease can improve sleep disorders.

Improving circadian rhythm disorders requires comprehensive lifestyle adjustments. Ensuring sufficient light exposure during the day and doing 30 minutes of aerobic exercise in the morning such as brisk walking and swimming can improve daytime alertness. Avoid high-fat and high-sugar foods for dinner, and choose foods such as millet and bananas rich in tryptophan to help you sleep. Avoid strenuous exercise 2 hours before going to bed and try progressive muscle relaxation training. If symptoms persist for more than one month or are accompanied by impairment of daytime function, it is recommended to seek evaluation from a sleep specialist. Keep your bedroom dark and quiet, and use light-blocking eye masks and earplugs to improve sleep efficiency. Keeping a sleep diary can help discover specific influencing factors, and if necessary, cognitive behavioral therapy or light therapy intervention can be carried out under the guidance of a doctor.
