Eating oranges 2-3 hours before bedtime can promote digestion, increase satiety and help you sleep. Oranges are rich in nutrients and contain a large amount of organic acids, fiber and vitamin C. The organic acids and fiber in oranges can promote gastrointestinal peristalsis, which is beneficial to digestion. Because oranges contain more vitamin C (every 100g of oranges contain about 33mg of vitamin C), eating oranges has become a common food to supplement vitamin C. And oranges are high in water content and also contain carbohydrates, so they can enhance the feeling of satiety. However, it is not recommended to consume oranges within half an hour before bedtime, because the human body’s gastrointestinal tract during sleep has a weak digestive function, and consuming oranges, there will be a large amount of acid and fiber intake, which may increase the burden on the stomach and intestines. And a large amount of water intake at night will increase the amount of urine, affecting the quality of sleep.
