Alpha waves are a type of brainwave that occur when a person is awake but relaxed. They typically range from 8 to 12 hertz and are most prominent when you close your eyes and begin to daydream or meditate. These waves are associated with a calm, alert state of mind, helping to reduce stress and promote a sense of well-being. Research suggests that alpha waves play a role in various cognitive functions, including creativity and problem-solving. They can also be beneficial for learning, as they help the brain process information more effectively. Techniques like meditation and deep breathing can enhance alpha wave production.
