With the 4-7-8 method, you breathe in through your nose for four seconds, hold that breath for seven seconds, and then let it out through your mouth for eight seconds. That holding part is super important because it gives your body time to soak up all the good oxygen. Plus, research shows it can help with heart rate variability and blood pressure, making it a great tool for relaxation and wellness. Give it a try when you need to unwind!
