What You Hear Shapes Your Perception

What you listen to actually shapes how you think — and it can even change your mood. The frequency of a sound can directly impact your mental state. In some countries, sound frequency is even used to help heal trauma. Places like India, China, Japan, Tibet, and Indonesia use sound healing practices to support people dealing with anxiety disorders and PTSD.

If you think about it, you probably already use music to shift your mood without realizing it. For example, most people wouldn’t feel very motivated to lift heavy weights while listening to slow R&B. That style of music carries a lower frequency and a calmer energy. When you’re working out, especially lifting heavy, your Root Chakra is activated — the chakra connected to survival and grounding — so higher, more intense frequencies tend to match that state better.

To really understand how frequency affects the brain, you have to look at the different brainwave states and their hertz levels:

• Beta (14–30 Hz): active, alert, sometimes stressed

• Alpha (9–13 Hz): relaxed, calm, creative

• Theta (4–8 Hz): deep meditation, intuition

• Delta (0.5–4 Hz): restorative sleep

  
  

Your brain is constantly shifting between these states depending on your environment. A key part of this process involves the amygdala — a small, almond-shaped structure in the temporal lobe. The amygdala plays a role in aggression, implicit memory (doing things without consciously remembering how you learned them), and emotional connections to memories. It’s also very sensitive to sound. Lower frequencies tend to calm the amygdala and reduce stress, while higher frequencies keep it alert and activated. This topic has always interested me because I’ve noticed that when I train, I naturally gravitate toward darker, more aggressive music. It actually makes me feel more intense, which helps when I’m lifting heavy.

My advice? Be mindful of what you’re listening to — in and out of the gym. Music really does affect your mind and your mood more than you might think.
