The time of day when you fell most energetic is when your cycle of body temperature-and-energy is at its peak.For some people the peak comes comes during the forenoon.For others it comes in the afternoon or evening.Much family quarreling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can’t change your energy cycle,but you can learn to make your life fit it better.Habit can help.Maybe you’re sleepy in the evening but feel you must stay later any way.Counteract your cycle to some extent by habitually staying up later than you want to.if your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour.This won’t change your cycle,but you’ll get up steam and work better at your low point.
Get off to a slow start which saves your energy.Get up wtih a leisurely yawn and stretch.Sit on the edge of the bed a minute befoe putting your feet on the floor.Avoid the troublesome search for clean clothes by laying them out the night before .Whenever possible,do routine work in the afternoon and save tasks requiring more energy or concentration for your sharp hour.
