Hydrate every hourAim for a glass of water per hour on board. Cabin air is extremely dry and dehydration worsens fatigue significantly.
☀️
Light is your reset switchMorning sunlight at your destination is the single most powerful signal to reset your circadian rhythm. Prioritise it above everything.
🌙
Melatonin (optional)0.5–1mg at destination bedtime can help reset your rhythm. Low dose works just as well as high - less is more.
🚫
Cap your naps20–30 minutes maximum, and always before 14:00 destination time. Long naps destroy your night sleep and extend jet lag.
🍷
Avoid alcohol on boardAlcohol at altitude worsens dehydration and fragments sleep quality even if it helps you fall asleep initially.
🧠
Shift your clock mentallyAs soon as you board, change your watch to destination time and start thinking in those hours. It makes a real difference.
