How Melatonin Tablets Work
Melatonin is a hormone produced by the body that synchronizes the body’s biological day-and-night rhythm.
The biological rhythm can be disturbed by travelling across time zones. This is known as jetlag. The symptoms and their severity vary between individuals, but are generally worse and last longer the more time zones are crossed.
Melatonin tablets can help restore the normal day-and-night rhythm and reduce the symptoms. You must talk to a doctor if you do not feel better or if you feel worse after 5 days.
Jet-lag can be recognized by sleep disturbances, daytime tiredness, fatigue, mild mental impairment, irritability and digestive system disturbances experienced after flying.
A good self care guide and information for jet-lag is available on the NHS website.

Ways To Reduce Jet Lag
Jet lag cannot be prevented, but there are things you can do to reduce its effects.
Get plenty of rest before you travel. You could start going to bed and getting up earlier or later than usual (more like the time zone of the place you're travelling to).
During Your Flight:
- drink plenty of water
- keep active by stretching and regularly walking around the cabin
- try to sleep if it's night time at your destination
- use an eye mask and earplugs if they help you sleep
Don't drink too much caffeine or alcohol - they can make jet lag worse
After You Arrive:
- change your sleep schedule to the new time zone as quickly as possible
- set an alarm to avoid oversleeping in the morning
- go outside during the day – natural light will help your body clock adjust.
Don't Sleep During The Day - only sleep at night time
