2. Milk
Milk has long been a staple in the average person’s diet, and is one of the most consumed beverages throughout the world. Milk is produced by the mammary glands of mammals, but cow’s milk is the most common. All mammalian offspring are fed solely by milk for the first few years of their lives, and humans are the only mammals that continue drinking milk into their adult years.
Although lactose, the sugar in milk, is unable to be properly digested by the majority of people, milk has many health benefits. Different types of milk have become much more popular throughout the years, especially milk alternatives such as soy milk, almond milk and coconut milk, which are lactose-free and easier to digest.
Cow’s milk is a rich source of calcium, which is a highly beneficial mineral that supports strong bones and teeth. It’s also a rich source of potassium, which is associated with vasodilation (the dilation of blood vessels) and helps to reduce blood pressure. Milk contains tryptophan, the key ingredient to serotonin (also known as the calming chemical), and is widely thought to be the reason why milk has a tendency to make us sleepy.
To make milk an even more effective sleep aid, warm it up before you drink it. Warm milk will raise your internal body temperature, which will make you feel calm, relaxed, and sleepy. If you don’t like the taste of milk, add some cinnamon, honey or nutmeg for an extra flavor boost.
