The secret to a good night’s sleep is a topic that generates plenty of heated debate, and there’s lots of conflicting advice out there on how to better your chances of snoozing soundly.
Whether you have a nightcap before bed or count sheep while tossing and turning for hours, there are lots of tips that have become common antidotes to a restless night under the covers.
According to a new study though, many of us may be self-sabotaging our sleep by following popular sleep myths that have little research behind them to prove they’re actually useful.
Researchers from New York University’s Langone Health’s School of Medicine combed through more than 8,000 articles to find the most common ideas around sleep and then asked a team of sleep medicine experts to explain which are unhealthy assumptions.
The findings, published in the journal Sleep Health, revealed there are many claims that could be damaging our health. Here are just five the researchers picked out:
“The literature on sleep and alcohol shows that alcohol consumed close to bedtime reduces sleep latency, but subsequently causes sleep disturbances in the second half of the night,” the researchers write.
“Alcohol has a negative overall impact on sleep, delaying the onset of REM sleep,” the study concludes.
They concluded that although you might “adjust” to being in a constant sleep-debt, you do so at the risk of serious health consequences.
Rather than being the sign of a good sleeper, they said that sleeping in uncomfortable places is “likely a sign of an underlying sleep problem.”
“One large cross-sectional study of US adults found that 52.7% of reported snoring and that snoring was associated with adverse health outcomes in its own right.
“Furthermore, snoring is a primary symptom of OSA (obstructive sleep apnea) that, when untreated, places individuals at elevated risk for adverse cardiovascular events.”
Although it sounds counterintuitive, the researchers found that those who practice something called ‘stimulus control therapy’ – where they leave the bed when they’re struggling to sleep – demonstrate improvements in sleep issues.
A healthy sleeper should be able to nod off in 15 minutes, so if you’re still awake at this point, the researchers conclude you should get up and do something that avoids blue light (so no scrolling through your phone). This could be anything from reading a book on the sofa to doing a repetitive task like folding washing.
Before you know it, you’ll be ready to give getting to sleep another go.
