Melatonin

What is it?

The hormone of darkness, melatonin maintains the body’s circadian rhythm. The circadian rhythm is an internal 24-hour clock that regulates when we fall asleep and wake up. The body produces melatonin when it is dark to encourage rest.

Is it out of whack?

Bright light in the evening or not enough light during the day can disrupt melatonin levels, which can result in weight gain. This is a common symptom of seasonal affective disorder (SAD), a winter ailment where too much melatonin is produced.

Quick fix: Regulating melatonin levels can help control weight gain, even without reducing the intake of food. Researchers from the University of Granada in Spain believe melatonin might help prevent heart disease associated with obesity, increase HDL (good) cholesterol and reduce LDL (bad) cholesterol. Small quantities of melatonin can be found in goji berries, almonds, sunflower seeds, cardamom, fennel, coriander and cherries. Melatonin also has strong antioxidant effects and can be taken in supplement form. If you prefer au naturale, be sure to sleep in a pitch-black room.
