    We have certain hormones in our bodies controlled by influences like what we eat or the effect of the weather.

    Two of these hormones serotonin (a neurotransmitter) and melatonin (a neurohormone) are made from an amino acid called tryptophan. When serotonin levels are high, melatonin levels are low and vice vera.

    Once tryptophan crosses the blood-brain barrier in our skull and enters our cerbral cortex if the amount of serotonin it produces it will make us happy and conversely if it produces higher melatonin it makes us sad.

    The level of serotonin or melatonin is controlled by the amount of light we receive through photosensitive ganglion cells in our retinas.
