Do You Know Sumaho Neck?

The season is fall, but now morning and evening feel chilly and there are a lot of people who become languid and aren’t refreshed. Now, there is a simple stretch method by which a body becomes relaxed in 30 seconds.

When looking at the smartphone and personal computer, people are looking face down without realizing it. The weight of the average adult’s head is said to be about 5 kg and often a hand is applied to the neck to support the head when you look down. When you are looking down, you don’t fence the sternocleidomastoid muscles exclusively on the left and right of the neck, but it’ll be contracted in the front and be in a tense state. This tension causes the poor posture, leading to stiff shoulders and poor health. This state is called SUMAHO neck (smartphone neck). Mr. Nobuyoshi Zhens, manual therapeutics teacher in Kobe, tells us a personal cure for SUMAHO neck.

“At first, put four fingers under your armpit and the thumb should be placed near the bottom of the clavicle. Raise the arm horizontally while tiling your head back. Hold this position for 15 seconds. The clavicle is fixed by suppressing the side and the sternocleidomastoid muscle is extended when you tilt the head. Please use the same height as a glance when using a smartphone. If your arm gets tired from holding the smartphone so high, put  the other hand under the armpit for support.”
