Exposure to light is often overlooked as a cause of sleeplessness. The latest research shows that even low exposure to light inhibits production of the melatonin hormone in the body. Melatonin is an important part of the immune system that gives the body the feeling of having slept well. With the soft relax sleep mask, you can eliminate exposure to light and thus lay the foundations for sound sleep. The black nylon mask with doubled elastic strap ensures the mask stays firmly and comfortably in place, obscures all light from the eyes and helps its owner drift off to sleep.

Whether at home or travelling, the mask is an indispensable tool for achieving relaxation and sound sleep. Your signature, logo or message can be printed on the black front of the mask in elegant gold or silver writing that stays in front of the eyes ofthe owner, wholl thank you for doing them good.
