Sleep is nothing but the way to rest our body, during which we are relieved from tension and the consciousness of world is suspended. We spend half of our life in sleeping. Even though it is a natural process many people don’t get sleep and spend sleepless nights but swallow medicines to get sleep. Nanotechnology comes to help people sleep well by proving a calming sleepwear. The sleepwear is fashionable and functional, and aesthetically pleasing aids to get sleep. Nano-technology enables the fabric to contain biomedical properties that relax and ease the anxieties. A combination of natural elements including; melatonin, tryptophan, calcium, chamomile, valerian are released into the skin during sleep. Light plays a major role in triggering the function of this sleepwear product. This calming sleepwear is inactive during day time while the nano-technology is inactive. In the night due to absence of light the relaxing properties within the garment are released over a given time span and the body gets relaxed and made easy to get good sleep. The fabric can be renewed by immersing in a replenishing solution.
