## Overview
Breathing gymnastics is a system of breathing exercises that focuses on the treatment of various diseases and general health promotion.
**Nafas** is a collection of breathing gymnastics designed to reduce the exhaustion of long working hours.
With multiple breathing patterns, **Nafas** helps you find your way to a detoxified energetic workday and also improves your concentration by increasing the oxygen level.
No need to walk away to take a break, just sit comfortably, run **Nafas** and let the journey begin.
**Nafas** means breath in Persian.
**Nafas** offers a selection of predefined breathing exercise programs.
Each program consists of multiple cycles.
The exercises begin with a gentle preparation phase to help users settle in and focus, followed by a series of timed inhales and exhales.
Between these breaths, the programs incorporate deliberate pauses that allow users to retain and sustain their breath.
These cycles aim to enhance both physical and mental well-being.
