Junk food affects your deep sleep: How our diet ruins our sleep patterns

Have you ever noticed that you wake up tired after eating junk food?

Specialists from Uppsala University conducted new research to explore the effects of junk food on general sleep quality.

The results can make some people rethink their diet.

Not just correlation

Participants tried both an unhealthy and a healthier diet randomly.

After eating unhealthily, the quality of people's deep sleep deteriorated a lot compared to those who were keeping the healthier diet.

While prior studies have linked diets with higher sugar content to poorer sleep, this study focused on direct effects.

Only 15 healthy young men participated in two experiments, each lasting a week.

The unhealthy option contained way more sugar, saturated fat, and various processed foods, while both diets had the exactly same calorie count.

It's time to rethink your diet

The experiment found that deep sleep exhibited less restorative slow-wave activity after regular junk food consumption.

The researchers suggest that diet may play a role in conditions like insomnia and aging that also impact deep sleep.
