Duration

~1 day per timezone। India→US East (9.5h difference): 7-10 days। India→Europe (3.5-5.5h): 3-5 days। Westward (day lengthens) easier than eastward। India→USA: outbound easier than return।

Tips

Melatonin 0.5-3 mg (available OTC in India at some pharmacies)। Sunlight at right time। Stay hydrated during flight।

⚡ CalcWolf Insight

Pre-adjusting your sleep schedule 1-2 hours toward the destination time zone for 2-3 days before travel significantly reduces jet lag severity. Go to bed 1 hour earlier per day for eastbound trips, 1 hour later for westbound. Combined with strategic light exposure, this can cut recovery time in half.
