Most replayed moment: Sleep myths that are ruining your rest | Dr Sophie Bostock

Sleep quality depends on consistent daily habits rather than singular dietary fixes or supplements. While turkey and cheese are often blamed for sleep disruption, evidence suggests these foods have minimal impact, with lactose intolerance being a more likely culprit for dairy-related issues. Magnesium may offer mild benefits for sleep quality, particularly for those under chronic stress, though its effects are subtle. Melatonin, while effective for shifting circadian rhythms in specific cases like delayed sleep phase disorder, is often misused for general insomnia and carries risks of inaccurate dosing in over-the-counter products. Optimal sleep hygiene centers on consistent wake-up times, morning sunlight exposure, and a structured wind-down routine that excludes smartphones. Cognitive shuffling—a technique involving the visualization of random, unrelated words—can further assist in quieting the mind to facilitate falling asleep.
