Using a smartphone while sitting significantly reduces respiratory function, impacting key measures like forced vital capacity and forced expiratory volume in 1 second. This highlights the importance of posture for lung health.
Area of Science:
- Physiology
- Public Health
Background:
- Smartphone use is prevalent globally.
- Sedentary behaviors and specific postures may affect physiological functions.
Purpose of the Study:
- To assess the impact of smartphone use posture on respiratory function in healthy adults.
Main Methods:
- Fifty healthy volunteers were divided into a control group and a smartphone group.
- Respiratory parameters including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, and peak expiratory flow (PEF) were measured.
Main Results:
- The smartphone group exhibited statistically significant reductions in forced vital capacity and forced expiratory volume in 1 second compared to the control group.
Conclusions:
- The specific sitting posture adopted during smartphone use can impair respiratory function.
- Awareness of posture during device use is crucial for maintaining optimal lung capacity.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
