Boarding: switch to Bangkok time
It is 19:30 in Bangkok. Set your watch and live on destination time from now on.
Stay awake until 23:00
Have your meal, stay active and avoid dozing off before your sleep window.
Sleep from 23:00 to 06:00 (7 h)
It is night in Bangkok. Eye mask, earplugs, no screens. Skip the meal if it falls in this window.
Wake up at 06:00
Open the window shade or switch on the light, have breakfast and move a little before landing.
Landing at 07:05 local time
Hold on until the evening: get outside in daylight, no nap longer than 20 minutes, go to bed around 10–11 pm.
First days at destination
- Light: get daylight in the morning and keep lights and screens dim in the evening. This is what helps your body clock move earlier.
- Naps: if you need one during the day at destination, keep it to 20 or 30 minutes so you can still sleep at night.
- Caffeine: no coffee or tea in the 6 hours before you plan to sleep.
- Hydration: drink water regularly and go easy on alcohol, which disrupts sleep and makes symptoms worse.
That is the general rule. The EOLE app adapts it to you.
The app builds your plan from your chronotype and your itinerary, then guides you through the flight: when to seek or avoid light, guided breathing and movement, hydration reminders, and an arrival plan for your first days. It works offline, in airplane mode. Free to download on iOS and Android.
General guidance based on chronobiology, not medical advice. If you have a health condition, are pregnant or take medication, ask a health professional.
