It’s National Sleep-in Day next weekend (25th October), where the nation gets to enjoy an extra hour in bed (if you’re lucky!). To help make the most of it, we’ve teamed up with sleep scientists who’ve created a formula for a great night’s sleep.
The formula for the best night’s sleep: Scientists reveal the equation that will deliver health and attractiveness
A recent study showed that people deprived of sleep for long periods appear less attractive and more unhealthy than those who are well rested – putting to bed claims that “beauty sleep” is a mere myth.
Following this research and the fact that Brits are clocking up less sleep than ever before, beauty and sleep experts Flint + Flint have joined forces with us to create a new specialist Sleeping Beauty set including a limited edition duvet, pillow and skincare.
We’ve also worked with Dr Penny Lewis and the Sleep Lab at Manchester University to devise the scientific formula for a great night’s sleep.
The formula reveals exactly what’s needed for the perfect night’s sleep; how the right combination of bedding, regime, temperature and light can massively improve your morning look and keep skin looking younger and fresher.
Beauty Sleep* = [(T x Bt) + C ] / [ Ha + S + L + (H x D)]
*Where 2 is a great night’s sleep, 1 is average and 0 is tossing and turning all night like the princess with the pea.
T = Tiredness: hours since your last overnight sleep – hours napping + hours of physical exercise.
Bt =Bed time: actual bed time that night / normal bed time.
C =Comfort: calculated as C = pillow + bedding + mattress – 9, where pillow, bedding, and mattress are self-rated from 1 (very uncomfortable) to 5 (very comfortable).
Ha =Average hours awake: this is how long you spend awake on an average day. For most people it will be about 16 hours.
S = Sound: any sounds except white noise or soothing sounds you’ve found to lull you to sleep. Use a scale of 1(very soft sounds) to 5 (very loud disturbing sounds).
L = Light: any light in the room, including illuminated clocks, natural lights and LEDs (where 0.1 is very soft light and 2 is very bright blue spectrum light).
H = Heat: degrees different from 16-17 degrees Celcius / 10.
D = Duvet appropriateness for room temperature: a good duvet can help keep a comfortable body temperature even if the room is a bit too warm or cold. If it is breathable, it can also prevent moisture build-up. Duvet appropriateness can be found by a self-rating from 0 (compensates perfectly for room temperature) to 3 (does not compensate and leaves you far too hot or too cold).
