A large part of having a good sleep environment is making sure your bedroom cues relaxation rather than wakefulness. This is why Dautovich advises people keep work, serious discussions, and TV watching out of the boudoir. It's also why some people use aromatherapy to improve their sleep. There are special pillows and bedding you can buy but if you're just starting out, give Bath & Body Works Lavender Chamomile pillow mist ($10) a test drive.
