Alcohol was once thought by many to promote sleep, but recent research has shown that while it can help you fall asleep quickly, it keeps you in a light sleep stage, making it difficult to enter deep sleep. Therefore, even if drinkers sleep for a long time, they still feel tired upon waking.
Foods that cause bloating Some foods produce more gas during digestion, leading to a feeling of bloating and interfering with normal sleep, such as beans, cabbage, onions, corn, and bananas.
Spicy foods In fact, eating spicy foods for dinner is another major factor that affects sleep. Chili peppers, garlic, and onions can cause a burning sensation and indigestion in the stomach, which in turn affects sleep.
Greasy foods Greasy foods increase the workload on the intestines, stomach, liver, gallbladder, and pancreas, and they stimulate the central nervous system, keeping it in a constant state of activity, which can also lead to insomnia.
Caffeine Many people know that foods containing caffeine stimulate the nervous system and also have a diuretic effect, making it a common cause of insomnia.
