Spending time in the sunlight will cause your body to increase the production of melanin since melanin is the body's defense against UV rays. increased pigmentation can be observed in individuals after only five to ten minutes of exposure to mid day sun.

UV: Sun, UV lamps, pregnancy, Addison's disease. Genetic variation is the big difference. Melanocyte stimulating hormone does not work on red-haired people or albinos or some others.
