As smart phones become more and more powerful, people's dependence on it is gradually deepening. At the same time, improper use of mobile phones brings troubles to our bodies. The "Active Living" website in the United States recently sorted out and summarized the "causes" of long-term improper use of smartphones.

1.Mobile elbow

The scientific name is "cubital tunnel syndrome". When the ulnar nerve in the cubital tunnel becomes inflamed or irritated, cubital tunnel syndrome occurs. This kind of pain is like being hit at the end of the ulna, commonly known as hemp. Keeping the elbow bent at a 90-degree angle for a long time can cause elbow pain. When talking for a long time, people will hold their mobile phones to their ears, and their elbows will naturally bend. This puts pressure on the nerves, which reduces blood flow and causes inflammation. Mobile phone elbows can cause numbness and tingling.

Therefore, we can try to change the way we hold the phone when making a call, and avoid holding the phone with the elbow bent at a right angle. If conditions permit, turn on the hands-free function, so you don't need to hold the phone to talk.

2.Little finger injury

When you answer the phone, the poor little finger has to work hard. It bears most of the weight of a smartphone, sometimes as long as an hour, causing indescribable pain.

However, this damage is not permanent. Take a break from time to time while using your smartphone to relieve the pain in your little fingers. Do hand stretching exercises every once in a while to stimulate blood flow and relax your fingers.

3.Bad posture

Smart phone users will often use it to check emails and read messages in WeChat Moments. Looking down at the phone repeatedly can cause hunchback and posture problems. Arching the waist or bending the neck can strain the muscles.

Try these good ways to correct your posture: sit with your waist up, place your phone at eye level, do not arch your back, and relax your body when making calls.

4.Wrist pain

Repeated hand movements can cause carpal tunnel syndrome. The carpal tunnel is a small passage close to bones and ligaments. When the median nerve is compressed, you will feel tingling and numbness in your thumb and other fingers, as well as weakness and weakness in your hands and arms. Constantly sliding the screen and typing can cause damage to the wrist and hand.

Wrist pain is a common complaint among smartphone users. Repetitive movements associated with excessive use of smartphones can also cause wrist disability.

5.Thumb pain

Although the touch screen makes communication easy, it adds a lot of work to the thumb. The tendon of the thumb becomes inflamed by repeated tapping movements. When the thumb is bent, inflammation can cause pain and rattling in the thumb.

The solution is to let the thumb take a break from time to time and use the other fingers to complete its work. If the pain persists, see an orthopedic doctor. A thumb splint (a hand cast used to protect and fix the thumb) can provide support for the thumb to reduce pain.

6.Eye fatigue

Excessive use of smartphones can cause eye strain and cause other problems.

Blinks are reduced People need to blink to keep their eyeballs moisturized. Blinking is a natural way to prevent the eyeball from getting in contact with dust and sunlight. Smart phone users stare at the phone almost without blinking, which reduces the time for the eyes to recover, leading to dry eye syndrome.

Squinting When the user reads the small font on the phone, it is easy to squint. This puts pressure on the eyeballs and blurs vision.

Glare The glare from the smartphone screen can cause eye strain.

In order to avoid the above situation, blink frequently to keep the eyeballs moisturized during use, put a layer of anti-glare film on the screen, reduce the brightness of the phone, enlarge the display font size, and keep the screen clean (wiping off fingerprints and dust can improve the clarity Degree) and place the phone 40~45 cm away from the face.

7.Spreading germs

Users will bring their mobile phones to various places, such as shops, gyms, and bathrooms, and germs contaminated in these places will be transferred to the smartphone. The germs that colonize mobile phones can spread various diseases. Some terrible bacteria thrive on mobile phones, such as:

E. coli If you have ever brought your mobile phone to the bathroom, it is very likely that you have been infected with E. coli. This bacteria lives in the intestines and is transferred to the feces. E. coli can cause diarrhea, food poisoning and other gastrointestinal problems.

Streptococcus This is another common bacteria that lives on smartphones. It not only causes strep throat in children, but also scarlet fever, necrotizing fasciitis and toxic shock syndrome.

Influenza virus Influenza virus can survive on smartphones for up to 24 hours. Therefore, you should wipe your phone with an alcohol cotton ball every day.

Staphylococcus This common bacteria also lives on smartphones. Some of these strains are very dangerous. They can cause skin infections and, in severe cases, can be life-threatening. Staphylococcus can also cause pneumonia and blood infections.
