Of the following travelers, who would require the most time to recover from jet lag?
a- mike, who is traveling east from chicago to paris
b- reba, who is traveling west from paris to chicago
c- kara, who is traveling north from lima to chicago
d- ben, who is traveling south from chicago to lima

Travelling from West to East ward direction causes more jet lag and hence requires more time to recover from jet lag. In this case, Mike’s travel from Chicago to Paris is from West to East is the right answer.  Option A.

Explanation:

Jet lag is a temporary sleep disorder that occurs when one travels through multiple time zones. Generally, multiple time zones needs to be crossed if travel is from West to East and vice versa. Our body has an internal clock (otherwise known as ‘Circadian rhythms’) that signals our body when to be awake and when to sleep. In the case of travel from West to East, from Chicago to Paris, local bedtime comes in advance than to the originated place and hence our body finds it difficult to sleep earlier than usually one does.

Due to this process, sleep pattern gets disturbed and it leads to jet lag. Hence, the more time zones, traveler crosses, the more his body clock gets affected and in this case, Chicago to Paris is a travel from West to East with more than two time zones are crossed, it would require the most time to recover from jet lag compared to other travelers, who travel from East to West or North to South and vice versa.
