As of 13 August 2026, AI can beat jet lag on a UK holiday.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the NHS pages on sleep and jet lag, and note any advice that applies to your journey.
   2. Gather your outbound and return flight times, airports, destination time zone, travel dates, usual sleep and wake times, and any fixed holiday activities.
   3. Write down relevant factors such as pregnancy, medical conditions, medicines, shift work and whether you will drive soon after arrival, without sharing unnecessary identifying information.
   4. Paste the gathered details and the prompt into ChatGPT, Claude or Gemini, then ask it to produce the plan in local time with the UK time shown beside any potentially confusing instruction.
   5. Compare the model's general recommendations and NHS links with the NHS pages you opened, removing any medicine, supplement or diagnosis advice that is not appropriate for you.
   6. Put the final sleep, light, nap, caffeine and alarm times into your phone calendar, then change them if your actual flight, symptoms or ability to sleep differs from the plan.
   7. Contact NHS 111 for urgent or worrying symptoms, or ask a pharmacist or GP before following a personalised plan if a health condition, pregnancy or medicine could affect it.

   Prompt

   I am travelling from the UK to [destination] for a holiday. My outbound flight leaves at [time and date] from [airport], arrives at [local time and date], and my return flight is [details]. The time difference is [hours and direction]. I usually sleep from [bedtime] to [wake time] UK time, and I need to be awake for [important activities or commitments].
   
   Create a simple jet-lag plan for the day before travel, the journey, the first days at the destination and the return journey. Use local times and label each time zone clearly. Cover light exposure, sleep timing, naps, caffeine, meals, hydration, movement and when to use an alarm. Keep it practical for a holiday and explain the reason for each main recommendation.
   
   Use current NHS guidance where relevant and link to the NHS page you used. Do not diagnose me. Do not recommend prescription medicines, melatonin, supplements or changing any medicine. If my age, pregnancy status, medical conditions, medicines, shift-work pattern or flight details make personalised advice unsuitable, say so and tell me to ask a pharmacist or GP. Tell me which parts are general guidance and which parts I must check myself. Include warning signs that should lead me to contact NHS 111, and do not present the plan as a guarantee.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
