So he stays up late and gets up early. 

Trump reportedly sleeps only three to four hours a night, which he described as a success tactic. "How does somebody that's sleeping 12 and 14 hours a day compete with someone that's sleeping three or four?" he asked.

“I would say he sleeps four to five hours a night,” Trump’s physician, Navy doctor Ronny Jackson, told reporters. “He’s probably been like that his whole life. He’s just one of those people who just does not require a lot of sleep.”
