The business of sleep is a multibillion dollar industry and one of the fastest growing areas in the wellness sector. Alarmed by studies proving the negative mental and physical effects of sleep deprivation, we decided to delve further and got in touch with Hong Kong sleep specialist Kate Bridle to offer scientifically proven advice that would help us lower our cortisol levels. According to Kate, warm-toned lighting that mimics candlelight; avoiding blue light; de-cluttering your bedroom; natural and breathable bedding that allows for temperature regulation; regular bedtimes; and a dawn-stimulating alarm clock are the arsenal necessary for some serious shut-eye. In a bid to get more shut-eye, we’ve rounded up our favourite sleep accessories to help us look at bedtime in a whole new (blue-blocking) light.
