Sleep techniques are methods designed to improve the quality and duration of sleep. Common techniques include establishing a regular sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep environment by reducing noise and light. These practices help signal to the body that it is time to wind down and prepare for rest. Another effective technique is the use of cognitive behavioral therapy for insomnia (CBT-I), which addresses thoughts and behaviors that contribute to sleep problems. Additionally, relaxation methods such as deep breathing, meditation, and progressive muscle relaxation can help calm the mind and body, making it easier to fall asleep.
