You find yourself nodding off around 2pm, rereading the same email three times and wondering whether you are really built for afternoon work? Nothing unusual there: your internal clock creates a dip in alertness in the early afternoon, and a nap remains one of the simplest preventive habits around. Free, accessible and fairly well studied.

What we know, and what we don't yet know

What is solid: a short midday break supports alertness, memory and mood. Current data suggest that regular napping may also be linked to a lower cardiovascular risk — a serious lead, not a certainty. Conversely, a very long nap can be a signal: poor-quality night-time sleep, or even undiagnosed sleep apnoea. Sleep deprivation and sedentary behaviour, meanwhile, remain well-documented risk factors, and no nap can replace a proper night's sleep. In practice, if you sleep badly at night and crash during the day, speak to a GP or healthcare professional: that kind of follow-up is worth far more than a casual opinion at the counter.

The power nap: 20 minutes, no more

Forget a three-hour daytime sleep: few people can fit it in, and even fewer come out of it feeling fresh. The formula that works is the power nap: 15 to 20 minutes. Enough to recharge, without dropping into a deep sleep cycle that leaves you in a fog when you wake. Any longer, and you risk a groggy awakening and the urge to keep going.

The best window? Just after lunch, when tiredness naturally rises. At home if you can, otherwise in a quiet chair at work — and if it reclines, even better.

Your body likes routine. By choosing roughly the same time each day, you will find it easier to fall asleep over the weeks: regularity is learned, not decreed.

Three formats depending on your time

  • 5 minutes, repeated. Before a meeting that makes you anxious: sit down, relax your shoulders and neck, breathe in slowly, exhale for longer. Close your eyes, think about something other than work. Even without sleeping, this buffer leaves you sharper.
  • 20 minutes, once only. The ideal format: a proper little sleep, a clear awakening.
  • On holiday. Treat yourself, but keep an eye on how easily you fall asleep in the evening: a late, long nap can delay it.

When you wake, don't leap up. Stretch, unfold your back and neck, get up slowly, drink a glass of water, take a few steps. Two minutes of transition beat a frantic restart.

Do you need any kit?

Short answer: no, and that is a good thing. If you want a bit of support, a sleep mask and a small cushion are enough. Check the composition: natural or recycled fibres, washable cover. On labels, GOTS-certified organic cotton guarantees an organic supply chain and social criteria; OEKO-TEX certifies the absence of unwanted substances above certain thresholds, but says nothing about organic origin. Also think about end of life: cardboard packaging, refills, repairability. Without those markers, a 'natural' claim on the label does not prove much.

Budget

  • Sleep mask: expect around £10–25 depending on the material; more for certified mulberry silk.
  • Small cushion: around £15–45, depending on the filling and whether it has a removable cover.
  • Earplugs or noise-cancelling headphones: around £10–35.

You will find entry-level options in supermarkets and online, and more traceable materials at bedding shops and specialist brands. The price gap comes down to certification and where it was made, not magic.
