Christmas can be a really good time to reacquaint yourself with your natural circadian rhythm, which may improve your sleep habits once the festive period is a distant memory.

“Recognise that over the festive break our perception of time changes (think about how hard it is to even know what day it is),” says Darwall-Smith. “And our energy levels naturally fluctuate more during the holidays. Allow yourself to flow with this rhythm, resting or napping as needed. This period is more about experiencing moments than sticking to a strict schedule.

“Ironically, by going with the flow and listening to our body, we have a chance to connect with our natural circadian rhythm which will improve sleep in the long run.”
