How do you invest in quality sleep? Is it by buying high thread count sheets? An expensive mattress? Designer PJs? Or by investing time in going to bed early, switching off from the world and simply closing your eyes?
Maybe your pantry is full of different types of chamomile tea or you have a favourite pair of fancy slippers that mean the world to you.
The best investment you can make in your health is to get good quality sleep, however you manage to get it. Making sleep a priority and finding out what works for you are both important. Remember how you feel when you wake up after a refreshing, unbroken night's rest. That's what you deserve!
