According to media reports, US President Barack Obama is a nocturnal person, and work majorly at night with just five hours of sleep through his hectic 24 hour schedule. And in his relentless schedule all that keeps him awake during his work is not pipping hot tea or coffee, but just a handful of salted Almonds, to be precise, 7 of them which keeps him going.

Obama calls himself a "night guy," and as president, he has come to consider the long, solitary hours after dark as essential as his time in the Oval Office. Almost every night that he is in the White House, Obama has dinner at 6:30pm with his wife and daughters and then withdraws to the Treaty Room, his private office down the hall from his bedroom on the second floor of the White House residence. According to his close sources he spends 4 to 5 hours largely by himself.
