Frequently asked questions
How do Indians beat jet lag flying to the US?
Flying from India to the US East Coast crosses 9.5-10.5 hours. Strategy: pre-adjust by going to bed 30-60 minutes later for 3 days before flight; sleep moderately on the flight (5-7 hours); arrive in the US afternoon-evening; resist napping; get bright outdoor light; eat at local meal times; melatonin 3-5 mg 30 minutes before US bedtime for first 3-5 nights. Active recovery is 3-4 days vs the natural 9-10 days.
Why is jet lag worse flying east than west?
Your internal circadian rhythm is naturally slightly longer than 24 hours (around 24.2 hours), so staying up later (west-shift) aligns with it, while going to bed earlier (east-shift) fights it. Flying east from India to Singapore, Bali, Japan or Australia requires advancing your body clock, which is biologically harder than the delay required for west-bound travel to Europe or the US.
Is melatonin effective for jet lag?
Yes, when used correctly. Take 3-5 mg of melatonin 30-60 minutes before your target sleep time at destination, for the first 3-5 nights. Higher doses do not work better and may cause next-day grogginess. Melatonin is prescription-only in India but OTC in most other countries — buy it at destination. Avoid if you are pregnant, on blood thinners, anti-seizure or autoimmune medication, or have depression/epilepsy. Consult your doctor first.
How does sunlight help with jet lag?
Bright sunlight (10,000-50,000 lux) is the strongest signal that resets your circadian clock — much stronger than indoor lighting. After flying east, get morning sunlight at destination to advance your clock. After flying west, get evening light to delay it. For winter trips with limited sunlight, a 10,000-lux therapy lamp (Verilux, Carex) used for 20-30 minutes substitutes effectively. Combine with melatonin for fastest recovery.
Should I sleep on the flight or stay awake?
Depends on direction. Flying east (to Japan, Australia), sleep aggressively — you want to arrive rested for active days. Flying west (to Europe, US), sleep moderately and partially. For India-US flights, 5-7 hours of sleep on the 14-15 hour flight is ideal so you arrive in US afternoon-evening able to function until US bedtime. Use eye mask, earplugs and neck pillow regardless of direction.
How long does jet lag last after India-US flights?
Natural recovery is about one day per time zone crossed, so 9-10 days from India to US East Coast and 12-13 days to West Coast. With active jet lag management (pre-flight schedule shift, controlled in-flight sleep, melatonin, morning light exposure, hydration, no alcohol), this compresses to 3-5 days. Most Indian business travellers feel functional within 48 hours but full sleep normalisation takes a week.
Does jet lag affect children and elderly differently?
Yes. Children typically recover faster because of higher melatonin production and more flexible circadian rhythms. Infants can struggle with the disruption but recover quickly. Elderly travellers (60+) recover slower because melatonin production declines with age. Both groups benefit from longer pre-flight adjustment periods, gentler in-flight schedules and more conservative use of light therapy.
