Physiological Factors

1. Environmental Factors: Prolonged exposure to loud noise or excessive light may cause the cerebral cortex to remain in a state of prolonged excitement, leading to insomnia.

2. Dietary Factors: Consuming coffee or strong tea before bedtime can easily overstimulate the central nervous system, also causing insomnia.

Pathological Factors

1. Vegetative Nerve Disorders: Due to factors such as genetics and age, some individuals may experience an imbalance between the sympathetic and parasympathetic nervous systems, triggering this disorder. Symptoms include palpitations, chest tightness, difficulty falling asleep, and shortened sleep duration.

2. Depression: Triggered by stressful events or introverted personalities, depression is a mental health disorder that can manifest as low mood, loss of interest, self-blame, anxiety, slowed thinking, and decreased willpower.

Furthermore, insomnia can also be associated with diseases such as hyperthyroidism and cerebral insufficiency. It is crucial for patients to seek medical treatment promptly.
