Pillow sprays, 'sleepy tea' and mindfulness are sold as the answers to sleeping better at night.
But poor sleepers should beware, as these 'sleep hygiene' solutions are likely to make their problem worse, an expert has warned.
People who fixate too much on their bedroom routine, with tricks like chamomile tea, a pillow spray, bath before bed, blackout curtains and yoga, may become too 'vigilant' about sleep, according to insomnia expert Kathryn Pinkham, a former psychological practitioner within the
NHS.
It might be better to try a technique of 'retraining' the body clock by spending less time awake in bed, and going to bed later, to increase the body's 'appetite' for sleep.
Speaking at the event Postcards from Midlife Live in London, Ms Pinkham said: 'Most people who come to me have tried everything - that will be their words - they've bought everything, they've changed everything, they've read everything, and they're still not sleeping well.
'If you think about the formula for where sleep problems come from, actually the more that you do to try and make it better, the worse it's going to become, because you're just trying too hard.
'Sleep hygiene is things like giving up caffeine, blackout blinds, giving up alcohol.
'None of that stuff is bad advice, but it isn't a cure for poor sleep.'
She added: 'You have this long wind-down routine where 'I have to have a bath, I've got to do my hour of yoga, I've got to have a sleepy tea, and I'm going to listen to my mindfulness.
'Actually all you're doing there is creating a really long routine (up) to not sleeping.'
