2. Keep your bedroom cool and dark.
The best temperature for sleep is 17oC - so open the window and make sure it's dark. If you don't have black-out blinds, a sleep mask is a great alternative. We love the Slip silk ones - definitely not the cheapest but we figure if you're using it every night, you might as well invest...
3. Use a pillow spray.
We aren't exactly sure of the science of this... But it seems to work. Some brands claim that combinations of essential oils work to calm and soothe the brain. There's also claims that associating a fragrance to sleep can help signal to our body that it's time to rest. However they work, thousands of people swear by them. And there's really very little downside from having a beautiful and soothing smelling bedroom.
4. Have a herbal tea.
Chamomile, in particular, is a great tea to sip before bed. Make your tea with whole buds (or bags containing whole buds) for the best effect.
