1. Spicy foods
Spicy foods increase acidity in the stomach and if you have a weak stomach valve, acid can go up the esophagus when you stay in bed. This sensation is also known as heartburn, and can become extremely painful in the chest area and will keep you up all night. Some specialty spices are known to contain glutamate, an amino acid that stimulates the brain and makes your body feel alert.
Many studies have shown that spicy condiments like tabasco, mustard, or chili have a negative effect on your sleeping patterns. After consuming these items, you are likely to have a hard time going to sleep and ultimately sleep less and not as deeply. So, you should avoid spicy foods before bedtime at all costs.
