When Jesus was physically living in this world, he spent a lot of time in prayer especially in the night time. He was moving around the province of Galilee helping people, delivering them from sickness, demon possession, preaching the word of the heavenly kingdom, sometimes feeding them, and even raising the dead. Naturally it is a tiresome ministry. He did not have any motor car or chariot to move from place to place except for a certain times the disciples took Him in the boat. When the disciples and the followers were sleeping he was in constant communication with the Lord especially when the world was calm and silent.
