Serotonin is also called the "happy substance" or "study substance" because it is associated with happiness and learning ability in modern people living busy lives. It also calms the mind and improves immunity, as well as promoting endorphin production.
Lifestyle factors that increase serotonin
1. Eat foods rich in vitamins B6 and B3, and magnesium
These substances are needed to make serotonin from tryptophan.
Foods rich in vitamins B6 and B3: brown rice, whole wheat, peanuts, shiitake mushrooms, oyster mushrooms
Foods rich in magnesium: Nuts and cereals, brown rice, whole wheat, spinach, radish leaves and vegetables.
2. Laugh out aloud
Laughing out loud makes you livelier and helps to create serotonin.
3. Think positively and appreciate yourself
Laugh at least 10 times per day, make sufficient body contact, and say positive comments to each other to help create a positive mind. Your hobbies and making time for your relaxation such as learning, meditation, and other hobbies also helps.
4. Sufficient exposure to sunlight for vitamin D
Make sure you are exposed to sufficient sunlight to ensure you have enough vitamin D production. Exposure to the sun for at least 15 minutes per day helps production of serotonin, and also helps keep depression at bay and boosts skin immunity.

Make sure that you consume five main nutrients (carbohydrates, protein, fat, vitamins and minerals) even if you have a simple meal.
