Why Can't I Fall Asleep at Night?

There are multiple reasons for being unable to fall asleep at night, mainly including: 1. Psychological factors: Excessive stress, irritability, excitement, or anxiety can all affect sleep. 2. Environmental factors: Noisy surroundings, overly bright lighting, extreme room temperature (too high or too low), or sudden changes in sleeping environment. 3. Physiological factors: Regularly staying up late, drinking coffee before bedtime, or engaging in vigorous exercise that causes brain excitement. 4. Age-related factors: With aging, secretion of melatonin decreases, which may lead to reduced sleep quality. 5. Medical conditions: Neurological disorders, psychiatric illnesses, endocrine diseases, and others may cause insomnia. The specific cause needs to be analyzed according to individual circumstances. If insomnia persists for a long time, timely medical consultation is recommended.
