Dodow Sleep Aid Device, £49
If you struggle to fall asleep or suffer with insomnia, this handy device is worth a try. Dodow’s sleep aid is inspired by behavioural cognitive therapy, yoga and meditation, designed to quickly soothe your brain activity, slow your breathing and relax your body to help you drift off. During an eight- or 20-minute relaxation mode, you’ll be led through breathing exercises controlled by a light sensor. Also suited for travel, this device is lightweight and has a decent battery life.
