Molecules Found On Phones Reveal Lifestyle Secrets-Study

2^min

Molecules found on mobile phones reveal an amazing amount about the owner's health and lifestyle - including their food preferences and medication.

Californian scientists found traces of everything from caffeine and spices to skin creams and anti-depressants on 40 phones they tested.

We leave traces of molecules, chemicals and bacteria on everything we touch.

Even washing hands systematically would not stop the transfer to daily objects, the researchers said.

Using a technique called mass spectrometry, the University of California San Diego research team tested 500 samples taken from 40 adults' mobile phones and hands.

They then compared them to molecules identified in a database and produced a "lifestyle profile" of each phone owner.

Dr Amina Bouslimani, an assistant project scientist on the study, said the results were revealing.

"By analyzing the molecules they left behind on their phones, we could tell if a person is likely to be female, uses high-end cosmetics, dyes her hair, drinks coffee, favors beer over wine, likes spicy food, is being treated for depression, wears sunscreen and bug spray - and thus likely to spend a lot of time outdoors - all sorts of things," she said.

Most of the molecules are thought to be transferred from people's skin, hands and sweat to their phone.
