Four popular foods and drinks that could be keeping you up at night

Fatty foods

Ms Garcia said: “Fatty foods, for their part, are difficult to digest and are thought to cause discomfort and make it harder to sleep.

“Research from the Federal University of Sao Paulo (Brazil) shows that a high-fat dinner, regardless of what is eaten throughout the day, increases the risk of disturbed sleep.

“After developing the study, the results reflected that its consumption implied a less deep and restful sleep, in which participants woke up a greater number of times, tossing and turning during the night.”

Alcohol

“Despite the fact that drinking alcohol before going to sleep initially causes drowsiness, its consumption affects the deep sleep phase and REM sleep by causing interruptions, thus having a double effect on rest,” she said.
