Caramel chips, candy bar, chocolate-covered strawberries, and other sweet treats can help people sleep better, according to a study from the University of California at Davis.
In fact, eating these foods may help us stay awake, a study found.
The research found that when subjects ate the chips, they also slept better than when they ate the strawberry drinks, and when they tried to drink the strawberry bars they didn’t feel the need to go to bed.
A previous study found that eating sugar-free chocolate or a chocolate-sugar substitute can help with daytime fatigue and fatigue symptoms in people who suffer from chronic fatigue syndrome.
In the new study, which is published in the journal Sleep, researchers analyzed how people in the study performed on a simple task to measure sleep.
Participants then had to sit still for 10 minutes while the researchers monitored their blood pressure and heart rate.
Participants were also asked to eat and drink at least one cup of coffee or a cup of sugar-sweetened soda per hour for 10 hours.
When they woke up the next day, they were given the same task, but instead of watching their blood rate or heart rate, they watched a video of themselves eating and drinking.
Participants who ate the chocolate chips performed better than those who did not.
“The findings showed that chocolate has a strong sleep-promoting effect, especially for those with a history of sleep apnea,” study co-author Dr. Michael F. Belsky, the Richard L. Loomis Professor of Psychology at UC Davis, said in a statement.
“It’s not surprising that chocolate, like other sweet drinks, has a sleep-enhancing effect.”
A previous experiment found that the chocolate-based drinks could also improve mood, although that was limited to a single person, the researchers said.
The study did not find any benefits for diabetics or those with sleep apnoea, a condition that makes it difficult to fall asleep or get into a deep sleep.
