Jet Lag Advice in London
Flying long-haul from London? Get practical jet lag advice on timing sleep, light exposure, melatonin options and fitting plans around business travel.
Long-haul travel is easier when your body clock is planned for
Jet lag is not a vaccine problem, but it is a travel health problem patients ask about often. If you are flying across several time zones for work, family or a short holiday, a poor first week can matter. City Of London Clinic in London can talk through practical jet lag planning, including sleep timing, light exposure, medicines where appropriate, and how to avoid making the first few days harder than they need to be.

A body clock dragged across time zones
Jet lag happens when your internal body clock is out of step with the local time at your destination. It is not contagious and it is not caught from a plane cabin. The problem is circadian rhythm: sleep, temperature, digestion, alertness and hormones are still running on the time you left behind. The usual pattern is familiar. You may wake at 3am in New York, feel wiped out during an afternoon meeting in Singapore, or find your stomach wants breakfast while everyone else is ordering dinner. Symptoms can include poor sleep, daytime tiredness, reduced concentration, headache, stomach upset and irritability. Eastbound travel often feels tougher because you are asking the body to sleep earlier than usual, although westbound trips can still ruin the first few mornings. Crossing three or more time zones is where planning starts to pay off.

No jab prevents jet lag, but timing can be adjusted
There is no vaccine against jet lag. The useful work is behavioural and, for some travellers, medicinal. A travel health appointment can cover when to shift sleep before departure, when to seek bright light or avoid it, how to use naps without destroying the next night, and whether caffeine is likely to rescue or sabotage your schedule. Melatonin is sometimes discussed for jet lag because it acts on the sleep-wake cycle. It is not suitable for everyone, and the timing matters as much as the dose. Taken at the wrong time, it can make the body clock move the wrong way. Some people also get drowsiness, headache, nausea or unusually vivid dreams. Sedating sleeping tablets are a separate issue and need particular caution, especially with alcohol, driving, work decisions, older age, pregnancy, certain medical conditions or other medicines. The best plan is usually made once your flight times, stopovers and first-day commitments are known.

Trips where jet lag advice tends to matter most
Jet lag planning is most useful for long-haul journeys crossing several time zones, particularly when you need to function quickly after landing. Common examples include the west coast of the United States, Canada, Mexico, the Caribbean, India, Singapore, Hong Kong, Japan, Australia and New Zealand. Business travellers often notice the cost most sharply: a presentation at 9am local time can feel like the middle of the night to your brain. Short European trips usually need less planning, although very early flights, overnight connections and tight work schedules can still cause trouble. Direction matters too. Flying east to Asia or Australia often needs a different approach from flying west to California.

Fit the plan around the flight, not after it
For jet lag advice, bring your itinerary, usual sleep pattern and any medicines you take. If you are travelling for work, include the meetings or tasks that matter most in the first 48 hours. The clinic is on Goswell Road, convenient for patients coming from Farringdon or Moorgate. Book once your flights are firm, and we can map a sensible plan before you leave.
