This Works Sleep Spray has become a bedtime must-have for a lot of people, particularly those that struggle to wind down after a hard day. If you know someone who needs a little help in chilling out, the This Works Dream Team Set (£10) is a perfect mini set to get them started, containing a Deep Sleep Pillow Spray and Stress Check Roll-On. Don't be surprised if they get hooked and request a set every Christmas and birthday, though.
