Strategic napping is also a power move to help refresh the brain for the afternoon. If you can wing it on your work break, the perfect nap time is just after lunch when the body takes a natural dip in so-called ‘alerting signals’ that regulate your sleep and wake.

Dr Victoria Revell, an associate professor in transitional sleep and circadian physiology at the University of Surrey, says this strategy can “help reset the build up of sleepiness you will be experiencing”.

She also advises that you set your alarm so you do not nap for too long, to get “a boost without affecting tonight’s sleep”.

For those who can not find a private spot to curl up this afternoon, finding somewhere to sit quietly for 10 minutes or so can also be helpful.

Importantly, try to go to bed around your normal time this evening to prevent long-term sleep disruption.
