What Foods Make Us Feel Sleepy?

Grapes

Individuals who have ever felt sleepy after drinking a glass of wine should know the feeling isn’t just coming from the alcohol. The Journal of Science of Food and Agriculture found evidence of melatonin in everything from the roots to the fruits of grape vines. Apparently, melatonin helps the fruit withstand the hot summer sun by preventing shriveling. The levels of melatonin fluctuate throughout the day and night, so the amount of it in grapes may even differ depending on the time in the season or the time of day the fruit was picked. Regardless of how beneficial melatonin may be for the grapes, for humans, it makes us just plain tired. That's just another reason to hold off on the wine until the end of the day.
