It’s 9:30 am, you’ve had your first coffee of the day, made your breakfast, and had your first work meeting. You feel energetic and ready for the rest of the day ahead – until, that is, 3pm hits.
Suddenly your work-to-do list feels longer than ever and you could do with an afternoon nap.
It usually happens after lunch and sometime before the end of the work day. You feel tired, sluggish and ready for a sleep – yes, it’s the 3pm slump.
If you’re currently feeling quite drowsy, don’t worry. Sleep physician Dr Abhinav Singh explains that the 3pm slump is a natural circadian dip for all who sleep at night.
“The circadian alerting signal takes a dip for half an hour or so at this time. This is a great time to take a nap or rest to feel more alert and rejuvenated,” Singh says.
However, if you’re sleep-deprived, he says that “you may feel this dip more than others and have a harder time waking from a nap”. If waking up after a 20-minute nap seems difficult, it may be an indicator that you’re sleep-deprived.
This is why some people take a nappuccino – aka drinking a small amount of coffee before a 20-30 minute nap. The caffeine takes effect after they wake and they feel an added boost of wakefulness.
So, why do we start to feel sleepy around 3pm?
Paediatrician and sleep expert Dr Nilong Vyas says there are many factors that can influence it. For example, it can depend on how much sleep you had the night before, if the circadian rhythm is off balance, and what you had for breakfast or lunch.
If you want to try and avoid it, you should start by looking at what foods you had or didn’t have before the slump, she suggests.
