Hello, I’m Leon Yang (楊里祥), a licensed counseling psychologist based in Taipei, Taiwan. I work with adults struggling with sleep difficulties — lying awake unable to fall asleep, waking repeatedly through the night, rising too early, or never feeling rested. Insomnia often shows up alongside stress, anxiety, or life transitions, and tends to develop a life of its own: the harder you try to sleep, the more elusive sleep becomes. My approach is grounded in Cognitive Behavioral Therapy for Insomnia (CBT-I), the first-line treatment for chronic insomnia recommended by international sleep guidelines — more effective and durable than sleep medications long-term. CBT-I targets the real engines of chronic insomnia: weakened sleep drive, disrupted circadian rhythm, conditioned arousal in the b ...
