Heat-beating gadgets selling like hot cakes

A mask called a "facekini", which first hit the market in 2004, has seen a spike in popularity among swimmers and beachgoers looking to prevent sunburn.

The mask covers the face, but reveals the eyes, nose and mouth, and is available in various colors, priced between 5 and 50 yuan. Its sales in June more than doubled compared with the same period last year, Taobao said.

Mini rubber thimbles are available that allow wearers to scroll up and down their handset screens without worrying about sweat gumming up the works.

A lightweight flexible tube that can be affixed to an air conditioner in an adjacent room can help cool down any location where people gather.
