If you'd like to know what Christmas treats are disrupting your sleep, and those that make you drift off into dreamland, Dr Verena Senn has the answers. This way, you can tailor your grazing, hearty meals and drinks to benefit you the most.
With a PhD in neurobiology, from Ernst Struengmann Research Institute, in Germany, and nearly 15 years in research on the brain, sleep patterns and psychological behaviour, Dr Verena Senn knows what she's talking about.
When it comes to Christmas, overindulgence tends to be the way, but Dr Senn advises against food comas.
"In fact, food comas are known to cause a myriad of health issues such as gastroesophageal reflux disease (GERD), heartburn and indigestion."
And although you may feel sleepy after a hearty Christmas feast, grazing on treats throughout the day "is likely to lead to less restorative sleep".
This means it shouldn't be a surprise if you keep waking up during the night.
"It’s not all doom and gloom," she cheers. "Simply hold off from falling asleep after eating for at least two hours."
