Sleep is an essential part of your health and wellbeing. Several physical and mental health disorders are linked to chronic insomnia. Long-term sleep problems increase your risk of health conditions such as high blood pressure, heart disease, diabetes, depression, anxiety, and chronic pain. CBT-I is offered as a stand-alone treatment or integrated into other therapies such as treatment for trauma, depression, chronic pain, acquired brain injury, sleep apnea, and anxiety. CBT-I is effective for those who take sleep medication and those wishing to eliminate or cut back on sleep medication.
