The human brain does not sleep even when we are sound asleep at night or resting. However, there are factors that affect the length of time that we take to get up from bed. It is dependent on your attitude towards the day and the activity that will get you out very early in the morning or late. If you know that you are going to a nice place in the morning, the brain will be stimulated to get you sleepless nights as you wait for morning to come. Therefore you will get up as soon as morning comes and as fast as you can.
