Smartphones have become an accessory when we go out on the street. It is not difficult to conclude this just by looking at the people we meet on the street. Because while the phone is sometimes carried in a bag or pocket, in many other cases it's in the user's hand as they walk around sending messages, checking social media or recording videos of themselves.
In addition to causing traffic accidents (in 2015, the Spanish Ministry of Transport warned that 98% of traffic accidents in which pedestrians were at fault were caused by the use of mobile phones), this kind of multitasking will also have a negative impact on our health. Posture, concentration and walking style are affected.
Changes in body posture
If we watch a video of a person using a mobile phone while walking, we will find that his arm holding the mobile phone is bent and slightly raised, and his head is tilted. In other words, we lose the swing of our arms when we walk by holding our phones.
Fernando Ramos, head of the Spanish Association of Physiotherapists, said: "The swing of the arms is very important to help stabilize the body and improve lateral balance when walking." Stopping the swing of the arms "may reduce stability when walking or cause being This forces the use of energy-intensive stabilization strategies, such as increasing activation of trunk muscles or adjusting stride length to increase the base of support and control the tendency for greater lateral excursion resulting from cell phone use.”
Improper head position
“This posture is characterized by a forward tilt of the head and a pronounced curvature of the cervical spine. Walking in this way places undue mechanical stress on the muscles of the neck and upper back,” notes Ramos. “For example, when When our neck is upright and consistent with the trunk, the weight of an adult's head is about 6 to 8 kilograms, but when we bend the neck, the weight on the cervical spine increases to 27 kilograms, which means that the cervical spine needs to maintain A 50 to 60 degree bend. "This change in posture can cause pain in the craniocervical area as well as in the shoulder and shoulder girdle area.
The occurrence of vision problems
“Continuously looking at mobile phone screens while walking can also cause visual fatigue.” explained Pilar Serra, professor of physical therapy at the University of Valencia in Spain. While this happens when we're standing still looking at our phones, when we're walking while using our smartphones, it can lead to accommodative fatigue or visual stress, which means it's harder for the eyes to focus from near objects like a phone screen. ) is transferred to a distant place (such as the surrounding environment)”. The expert pointed out that staring at the screen for a long time will cause the ciliary muscles of the eyes to become tired, and the eye muscles need to work harder.It takes a long time to relax and focus into the distance.
Increased risk of falls and accidents
At the same time, Ramos stressed: "Using a mobile phone while walking significantly increases the risk of falling or having an accident in urban environments, with shocking figures showing that 7% of road collisions in Spain are related to the use of mobile phones. More than 50% of people have collided with other people or objects while using their mobile phones."
Reduce the benefits of walking
Additionally, many of the benefits of walking are diminished if you use your phone while walking. "Using your phone while walking can cause an increase in cortisol, a stress-related hormone, which can negatively impact our mood and reduce the positive effects of walking in keeping us physically active and healthy," Ramos said. /Tian Ce)
