Bali (WITA)

Current local time
Question 1 of 6
How many time zones did you cross to reach Bali?
Bali is UTC+8. Compare with your home timezone. E.g. Sydney (+10) = 2 zones, London (+0) = 8 zones, Los Angeles (-8) = 16 zones.
1–2 time zones — nearby (Singapore, Perth, Darwin)
3–5 time zones — moderate (Tokyo, Seoul, Mumbai, Sydney)
6–9 time zones — significant (Dubai, Europe, Cape Town)
10–13 time zones — severe (UK, Western Europe)
14+ time zones — extreme (USA West Coast, Americas)
Question 2 of 6
Total flight duration (including layovers)?
Longer flights = more dehydration, more radiation exposure, more muscle stiffness, and more circadian disruption.
Under 4 hours — short haul
14–20 hours — ultra long haul
20+ hours — extreme (multi-stop, Americas)
Question 3 of 6
How well did you sleep on the plane?
Sleep deprivation is one of the biggest drivers of severe jet lag symptoms.
Slept well — 5+ hours of good quality sleep
Slept a little — 2–5 hours, disrupted
Barely slept — less than 2 hours, very uncomfortable
No sleep at all — awake the entire flight
Question 4 of 6
What symptoms are you experiencing right now?
Select the option that best describes your current state.
Feeling mostly fine — maybe slightly tired
Fatigue + mild headache, slightly out of it
Significant fatigue, headache, trouble concentrating, feeling disoriented
Severe fatigue, nausea, dizziness, body aches, unable to function normally
All of the above + vomiting, extreme weakness, can barely get out of bed
Question 5 of 6
Did you consume alcohol or caffeine during the flight?
Cabin air is already very dry (10–20% humidity vs 40–60% normal). Alcohol and caffeine both act as diuretics, dramatically increasing dehydration at altitude.
No alcohol or caffeine — only water
1–2 drinks or coffees — moderate consumption
3–5 drinks or coffees — significant consumption
Multiple alcoholic drinks — business or first class / long celebration
Question 6 of 6
When did you arrive in Bali (local time)?
Arrival time affects how disruptive the jet lag is — arriving at night is generally easier than arriving in the morning when your body wants to sleep.
Evening (18:00–22:00) — easiest adjustment, sleep soon after arrival
Morning (06:00–12:00) — must stay awake all day, moderate difficulty
Afternoon (12:00–18:00) — afternoon slump hits hardest, difficult
Very early morning (00:00–06:00) — most disruptive timing
