Serotonin and melatonin are neurotransmitters which help in calming down the brain and induce sleep. Tryptophan can be found in almost all dairy products.

  1. Drink a glass or a cup of milk (without sugar) as a late-night snack
  2. Eat a dairy product like paneer for your dinner

Glutamine helps in governing sleep through its stimulating action on GABA (Gamma Amino Butyric Acid), which is a neurotransmitter that signals your body to go into “rest” mode. GABA is also associated with the feeling of calmness, relaxation, peace of mind, and greater quality of sleep.
