Why Deep Thoughts Hit Hardest Past Midnight?

Several factors contribute to the intensity of thoughts and feelings late at night. As distractions diminish (fewer daily tasks, less sensory input), our minds are left free to ruminate. Fatigue can also lower our self-control and inhibitions, making emotions feel more raw and thoughts less filtered. Our circadian rhythm and hormonal cycles (like melatonin production) also influence mood and cognitive processing, often leading to a more introspective and emotionally vulnerable state during the quiet hours.
