So while rest days are absolutely for resting, active recovery practices can be useful to shake off the sluggish feeling and “prevent the sudden drop in energy levels that can happen if you just do nothing,” says Dr Oluwajana.

Plus, a walk or a gentle yoga class can help release endorphins and get you out of the house – an often overlooked part of feeling energised. Getting outside within the first hour of waking up is also an easy way to spike your cortisol and wake you up without fatiguing the muscles that need a well-earned rest. Eating enough and eating well are also crucial, and stick with your usual bedtime and morning routines if you can.
