Discover the five brain waves and how they influence your thoughts, focus, emotions and sleep

Whether you’re solving a tricky problem at work, zoning out during a conversation, or suddenly remembering something from years ago, your brain is always busy. Behind these everyday activities lies a continuous stream of tiny electrical signals, generated as billions of brain cells communicate with one another. These signals, known as brain waves. They shift throughout the day depending on what you’re doing, how you’re feeling, and even how well you slept the night before.

So, what exactly are these brain waves, and why do they matter so much?

What are brain waves?

Brain waves are the brain’s natural electrical rhythms, created when nerve cells, or neurons, communicate with each other. These signals help the brain process information and control functions such as movement, memory, emotions, and sleep.
