Dim the lights.

Dimming the lights before bedtime makes it easier to move from activity to rest and sleep. Prioritise doing chores that require more light in the early evening, then spend the last few hours in an atmosphere with softer light. For example, with amber-coloured bulbs. 

Why it helps:
Bright light and the blue light from digital screens disrupt your circadian rhythm. Watching TV, your mobile phone or being in bright light simply makes it harder to unwind.
