People who are using old-fashioned phones now have a reason to change phones: according to new research, classic keyboard models like the Blackberry easily contain nickel, a metal that causes a rash. like eczema, more than touch phones.
Dermatologists and allergies have warned about phone-related skin problems 10 years ago when patients were hospitalized with red, dry, itchy, swollen speckles. cheekbones, jaw and ears Doctors have found that these rashes tend to disappear on their own if the patient stops using the mobile phone.
Many reports of similar cases have been linked to alkaline substance allergies on mobile phones, which affect 17% of women and 3% of men. Skin problems associated with this type of allergy are often caused by earrings or other jewelry such as wrist watches, belt buckles, dental implants and makeup.
Phones that use nickel materials can cause skin diseases for owners
To confirm the assumption that some phones are worse than others, researchers at Winthrop University Hospital, Mineola, New York, tested a total of 72 phones of 5 brands and 16 other models. together. The researchers examined the cover of each phone with a special nickel detector in five locations such as keyboards and speakers.
No iPhone or Android model reacts positively to nickel, while it is found on nearly 30% of Blackberry phones and 90% of phones with keyboards, including 6 types of Samsung and 9 types of LG . Cobalt element, another metal that can cause allergy, is also common on key phones, although it is not as common as nickel.
Phone manufacturers now use lighter materials such as plastic or copper to create aesthetics for the product. According to Luz Fonacier, head of the allergy department at Winthrop University Hospital, 'for those allergic to nickel, this may turn into a good thing.'
More than 230 million Americans are using mobile phones. Nickel can be found in most phones but only occasionally attached to external parts, usually around buttons and keyboards. According to Mr. Fonacier, that explains why there is no nikeo on the iPhones and Android touch screens.
Jeannette Graf, a dermatologist at Mount Sinai School of Medicine in New York, says mobile phone allergies are extremely rare but are not unprecedented for those with nickel allergies.
People who use mobile phones if they suspect they have a nickel allergy need to see a doctor to check. Simple treatments can be applied such as choosing another phone, using a wireless headset or buying a plastic cover for the phone.
