What are the symptoms of sleep disorders?

Sleep disorders typically present with symptoms such as difficulty falling asleep, frequent awakening during the night, early morning awakening with inability to fall back asleep, light and fragmented sleep, and excessive daytime sleepiness. If these symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Detailed explanations are as follows:

1. Difficulty Falling Asleep

Imbalance between excitation and inhibition in the brain's nervous system, along with overactive thinking before bedtime, makes it hard to relax. Remaining awake for more than 30 minutes after lying down is common. This is often accompanied by repetitive thoughts about trivial matters and difficulty concentrating. The harder one tries to fall asleep, the more alert they become, creating a vicious cycle.

2. Frequent Nighttime Awakening

Disruption of the sleep cycle leads to shortened periods of deep sleep, making individuals easily awakened by slight noises or changes in light. Waking up more than twice per night and requiring a long time to fall back asleep afterward disrupts overall sleep continuity.

3. Early Morning Awakening with Inability to Return to Sleep

Waking up more than two hours earlier than the intended wake-up time, with heightened mental alertness upon waking, making it impossible to fall back asleep despite attempts. This condition is often associated with emotional stress and may be followed by dizziness and fatigue upon rising.

4. Light and Short Sleep

Poor sleep quality characterized by a state of being neither fully asleep nor awake. Individuals remain aware of their surroundings, experience frequent and disordered dreams, and feel no sense of refreshment after a night’s sleep. Instead, they feel physically exhausted, as if they had not rested at all.

5. Excessive Daytime Sleepiness

Inadequate or poor-quality nighttime sleep results in insufficient oxygen supply and rest for the brain, leading to persistent drowsiness during the day. Concentration becomes difficult at work or school, and sudden urges to sleep may even occur while standing or walking, affecting daily functioning and safety.

If any of the above symptoms are observed, lifestyle adjustments should be made first. Avoid consuming coffee or strong tea before bedtime, and turn off electronic devices. Keep the bedroom quiet and dark, maintain a consistent sleep schedule, and engage in moderate outdoor physical activity during the day to improve physical health. If symptoms persist, seek medical attention promptly to identify the underlying cause and receive appropriate intervention.
