Many people often have the habit of holding smartphones with one hand and scrolling with their thumbs, which can cause a lot of unexpected harm.
Unexpected side effects
If you are holding your phone with the little finger supporting the bottom, the index, middle, and ring fingers lifting the back and the thumb to scroll the screen, you should probably stop immediately because it causes a lot of damage to your fingers. , wrist and neuromuscular.

|Unexpected harms when holding smartphones in the wrong way|
Smartphone pinkie is the term used to describe the condition in which the little finger can be deformed due to the wrong way of holding the smartphone. Hand therapist Ann Lund says the little finger is the smallest so it won’t be able to withstand the pressure of being hit by something heavier. Michelle G. Carlson, a hand and limb surgeon at the Hospital for Special Surgery in New York, says using your little finger to support the weight of your phone can strain the ligaments that connect your fingers to your hand.
The above sounds terrible, but that’s not all. Ben Lombard, a member of the British Chartered Physiotherapy Association, told HuffPost UK: ‘We tend to place our pinkies on the bottom of our phones and bend our wrists inwards so we can see the screen. This can cause compression of the ulnar nerve if maintained for a long time.” The ulnar nerve is one of the three major nerves in the arm that runs from the armpit to the elbow and to the little finger, and it controls nearly all the small muscles in the hand. Compression of the ulnar nerve causes peripheral neuropathy or nerve damage.
In a 2017 study, Peter White, assistant professor in the department of health technology and informatics at Hong Kong Polytechnic University, looked at the effects of excessive use of electronic devices on the median nerve. (median nerve), this is the only nerve that passes through the carpal tunnel to help us move our forearms, wrists, hands, and fingers. Mr. White found that students who held electronic devices more than 5 hours a day suffered more wrist and hand pain than those who did not use much (less than 5 hours a day).
So how should you hold the phone?
In follow-up research, White found that lateral flexion of the wrist can lead to marked deformity of the median nerve. To minimize damage, it’s important to keep the wrist as straight as possible, and limit flexing of the thumb and other fingers when using a smartphone, especially when using one hand.
Dr Steve Beldner said that since smartphones are usually quite thin, put a rolled up towel or T-shirt behind the phone. This keeps the thumbs away from the palm when in use, reducing stress on the joint.
Hand therapist Dina Delopoulos advises smartphone users to regularly rest and stretch or stretch by pushing their fingers up and back, or pulling perpendicular to the wrist.
In general, constant smartphone use causes not only mental health problems but also physical harm. Therefore, it is advisable to practice good habits as well as limit frequent phone use.
