Jet Lag

Jet lag medication

Jet lag is a common experience for travellers; it is a temporary sleep problem that can affect anyone who is travelling across multiple time zones in a short space of time, especially when moving from east to west. Jet lag occurs when the circadian rhythm which regulates our sleeping and waking patterns is confused and moves out-of-sync with the new time zone.


Since jet lag is a sleep-based condition, many of the symptoms you’re likely to experience are sleep-related. You may experience one or all of the common symptoms – these include:

  • Disturbed sleeping and waking patterns - difficulty sleeping at night and waking up.
  • Tiredness and exhaustion during the day.
  • Difficulty concentrating and functioning as you normally would.
  • Generally feeling unwell - leading to diarrhoea, bloating and constipation.
  • Mood swings.
  • Short losses in memory due to underperforming functions.


Jet lag is not a life threatening disease but it can make you lose vital holiday time, if you want to make the most of all the time you have travelling we can advise you on how to achieve this, including sleeping tablets, and providing lifestyle and nutrition advice.
