478 breathing is a simple yet powerful breathing technique that can help to reduce stress, anxiety, and insomnia. It is based on the ancient yogic practice of pranayama, which involves controlling the breath to achieve a state of relaxation.

The 478 breathing technique is very simple to do. Here are the steps:

Sit comfortably with your back straight and your eyes closed.
Inhale quietly through your nose for a count of four.
Hold your breath for a count of seven.
Exhale completely through your mouth, making a whooshing sound, for a count of eight.

You can practice this technique as many times as you need throughout the day. It is especially helpful to practice it before bed to help you fall asleep.

There is some scientific evidence to support the benefits of 478 breathing. It can help to reduce anxiety and stress in people with anxiety disorders.
