Fatigue, headaches and reduced energy are common symptoms associated with a variety of conditions, many of which are treatable through lifestyle measures. Since diet and sleep are vital toward maintaining proper energy and basic wellness, common causes of headaches, fatigue and reduced energy include sleep problems, poor diet, caffeine withdrawal and nutrient deficiency-related anemia. Serious or long-lasting symptoms, and those accompanied by additional symptoms, may require medical attention. For best results, doctor's guidance is suggested.
Sleep Problems
Sufficient, restful sleep plays a significant role in physical and emotional well-being. When sleep is disrupted on a continual basis, due to emotional stress, schedule changes or sleep disorders, headaches, fatigue and reduced energy may occur.
According to the National Sleep Foundation (NSF), headache and fatigue are common symptoms in women of sleep apnea, a disorder in which a person stops breathing repeatedly during the night. Insomnia--the inability to fall or stay asleep--may cause similar symptoms.
According to Grace W. Pien, M.D., M.S., assistant professor of medicine at the University of Pennsylvania School of Medicine, adults generally require 7 to 8 hours of restful nightly sleep for optimum health.
Skipping Meals & Low-Calorie Diets
Eating regular, balanced meals and sufficient amounts of calories--energy derived from food--is key toward maintaining energy and wellness. According to research published in "Nutrition Research and Practice" in June 2008, children who skip meals or regularly consume too few calories are prone to headaches including migraines, fatigue, poor energy and poor scholastic performance.
Children of low-income families and those who dine alone exhibit higher instances of skipping meals and its negative consequences.
A "Life Extension Magazine" report from September 2003, describes headaches, depression and fatigue as common side effects of severe calorie restriction; thus, individuals who consume low-calorie diets for weight loss or enhanced wellness may experience these effects.
Caffeine Withdrawal
Caffeine is a bitter substance that adds stimulant properties to beverages, foods and dietary supplements. Though moderate caffeine intake, or the amount found in 2 to 3 cups of coffee daily, is considered generally harmless, excessive intake is associated with caffeine dependency and potential withdrawal symptoms, according to the NSF. Headache is a primary symptom of caffeine withdrawal, along with lethargy, mental fogginess, reduced energy and irritability.
Anemia
Headache, fatigue and reduced energy may indicate anemia, a disorder characterized by red blood cell deficiency. Additional symptoms of anemia may include shortness of breath, dizziness, pale skin, cold body temperature and increased heartbeat. According to the Mayo Clinic, anemia may be prevented or treated through healthy dietary measures.
