"Never go to bed on an argument." It's a sage piece of advice that has been handed down through the generations, but new research shows that going to bed without a kiss goodnight could be just as bad for your sleep quality.
To mark International Kissing Day, yesterday (6th July), we're sharing our new research which reveals that 36 per cent of Brits have a disturbed night's sleep if they neglect to pucker up with their partners before bedtime.
The poll of 1,000 Brits found that 71 per cent slept better after giving their loved ones a goodnight kiss, with Scottish respondents being the most convinced that a kiss is the key to a good night's sleep (74 per cent).
However it isn't all sweetness and light, 57 per cent of Brits admitted they argue with their partner in bed, compared to a paltry 15 per cent which used bedtime as an opportunity to tell their partner they love them.
Silentnight's sleep expert Dr Nerina Ramlakhan, commented on the findings: "Sharing a kiss with the one you love before bedtime shifts your mindset away from the stresses of the day. Hearing that people sleep better after a good night's kiss makes sense, as kissing decreases the stress hormone, cortisol and increases serotonin levels in the brain*, so can have a similar effect to meditation, which is a great way to drift off."
