If you are travelling in the near future then you may have heard about jet lag and want to know how you can avoid it. Jet lag occurs when you travel across several time zones, and your body’s internal clock does not match up to the actual time at your travel destination. Jet lag sufferers can experience tiredness and headaches, and more severe symptoms even including depression. Melatonin has been found to potentially prevent jet lag. Melatonin is the body’s natural hormone that regulates when we feel sleepy and alert, and taking melatonin supplements may be one way to experience no jet lag.
