One of the primary hormones produced in our brain that allows for quality sleep is Melatonin and is located in the pineal gland. This pineal is found in the epithalamus, near the center of the brain, between the two hemispheres. Melatonin helps control your daily sleep and wake cycles and regulates your “internal clock” known as your circadian rhythm. As the sun begins to set our body recognizes this and begins to adjust melatonin levels accordingly. Melatonin and other sleep and growth factors rise through the early evening and maintain levels appropriate for sleep overnight. As the sun begins to rise our body senses this and starts producing less and allowing us to wake refreshed the day before.
Any number of factors both environmental and physiological can cause variations is melatonin release. Stress, anxiety, stimulants too late in the day, working overnights, external interruptions in normal sleep routines, hunger, depression… the list goes on and one. However, many people find that by supplementing with Melatonin, their sleep patterns can stabilize lowing them to fully recover from a challenging day’s work, stressful day with the family or grueling training session in the gym.
