Problem
You often are so tired that you can barely get through the day at work, and you have little or no energy for your partner, your children, running errands, and the like. Some people don't complain so often as often like some others, but they may suffer just as much.

Cause
There are lots of reasons that you might be fatigued. Depression, stress, overwork, lack of exercise, sleep disorder, side effects of medication, and dietary habits are among them.

How Serious
Fatigue can be a symptom of many different serious illnesses, but most often it is not. If you're eating well and getting plenty of rest yet are still constantly tired for more than six months even with vacations, then you should go consult your family doctor.
Fatigue from sleep deprivation also can be serious because it makes you more likely to have an accident. Sleeplessness could cost U.S employers more than $18 billion a year lost of productivity, the National Sleep Foundation estimates. Some guys may suffer from chronic fatigue syndrome, a mysterious ailment characterized by lethargy, sore throat, headaches, muscle pain, and other symptoms. Only about 1 out of 1,000 adults, however, is thought to have this condition.

Solutions
Listening to upbeat music can be a great way to find some extra energy but not pop and hard rock music, because it can make you jitterier than energized. --- Barbara Anne Scarantino in Music Power: Creative Living through the Joys of Music.
