A manicure has benefits. A regular cut and polish keeps our nails tidy and clean, while many women feel that nicely manicured nails enhance their appearance.

However, do you know that gel manicures, which give the quick-drying polish that lasts for weeks without chipping, losing its sheen or dulling, can cause serious damage? According to a Yahoo! report, Dr Dana Stern, a New York City based dermatologist specialising in nail disorders, says gel polishes paint on like traditional nail lacquer, but they have a chemical composition that enables them to immediately harden to a glossy finish when cured under a UV light. "The UV light that cures the product is in the same spectrum that contributes to photo-ageing. They're essentially little tanning beds," she said. They come with the threat of dark sunspots on your hands, and possibly skin cancer due to prolonged and repetitive exposure.

Sleep positioners

Many parents use a sleep positioner to help their babies nod off. Babies seem to like them as they provide a snuggly environment, which encourages a sound sleep. However, The New York Times published an article on the dangers of this device, saying health officials are now warning parents against using this product to help keep babies in certain positions when they sleep. This product has been linked to at least 13 deaths in the last 15 years, officials with two federal agencies stated.

Manufacturers claim the device aids babies' food digestion, and eases the symptoms of acid reflex and flat head syndrome, while reducing a child's risk of sudden infant death syndrome (Sids), which kills thousands of babies every year. Health officials say the device has never been shown in studies to prevent Sids and may raise the likelihood of sudden infant death.
