An IT professional working at Technopark, was finding himself with an
upset stomach every night and this went on for several weeks. While
normal medical checks revealed nothing wrong in him, deeper probes
revealed the reason that his stomach was collecting significant
amounts of wax. Doctors surprised wondered where from the wax came. On
investigating, they identified the villain - the ordinary paper cups
this IT professional used for drinking his tea at his office pantry
was the culprit.

Disposable paper cups have become quite popular in office pantries due
to the convenience it offers. What many overlook is the fact that
these paper cups are coated with a tiny layer of wax, which is
essential to prevent water from seeping into the paper. When very hot
liquid is poured over this cup, the wax disintegrates and a little
comes off, which is promptly sent along with the drink into our
stomachs! While our body can discard minor amounts, over long-term, it
does become a problem. So what can be done about it?

good reason). However, glass does have the problem of breaking easily,
so it requires good care. Ceramic cups are probably the best bet. Of
course, you can also use your ordinary stainless steel glass,
