Millions of Americans describe themselves as exhausted on a daily basis, many of them shuffling through life with little energy for enjoyment or satisfaction.

The first step in combating weariness is understanding why you're so tired. For some, the reasons may be obvious ... a newborn in the house, a stressful life change, a health issue or even the time change you forgot about. But for others, the reasons may be more clandestine. The primary causes of exhaustion are issues dealing with sleep, diet or exercise. Take a look at each of these and find out which one fits your situation and what you can do about it.

1. Sleep. Like I said, some of the reasons for fatigue may be obvious and a lack of sleep is definitely one of the more blatant culprits. According to a study by the National Sleep Foundation, 45% of adults say they've been affected by poor sleep in the last week. About one-third of Americans don't get the recommended minimum seven hours of sleep each night, according to the Centers for Disease Control and Prevention (CDC).

Some causes of sleep issues — like poor diet or lack of exercise — are controllable. Others, like the birth of a new baby are less so. For parents of newborns, rest assured that most little ones will start sleeping through the night within a few weeks. But if a new baby is not the cause of your sleep trouble, try avoiding alcohol and caffeine, turn off the TV and other screens within an hour or so of bedtime, and try going to bed and waking up around the same time each day to get on a better schedule. Here are lots of other tips for getting better sleep.

2. Diet. Let me guess. You start the day with a caramel macchiato latte and a blueberry scone only to crash with fatigue before mid-morning. And you combat that sleepy feeling with another latte and maybe a bagel to hold you over until lunch. The caffeine-sugar-caffeine cycle brings on a wild ride of ups and downs. Sure, caffeine and sugary foods may give you a rush, but that rush rarely lasts long. Your better bet is to reach for water and a healthy snack when you are tired to give you a longer-lasting burst of sustained energy. Speaking from experience, if you decide to give up the caffeine and sugar cold turkey, be prepared for a whopping headache. Instead, pump the water, turn to healthy snacks and hang in there for a day or so. Your energy level should improve.

3. Exercise. A healthy dose of exercise not only gives you more energy during the day, it also helps you sleep better at night. Even a 10-minute walk can give you more lasting energy throughout the day than a caffeinated calorie bomb from the coffee shop. But who wants to exercise when you are exhausted? Start slowly with an easy walk around the block after dinner, during your lunch break, or whenever you can squeeze it in. Every few days, add several more minutes to your walk or pump up the speed to improve your fitness and your energy level. With your doctor's approval, aim for about 40 minutes of exercise at least four days each week.

While sleep, diet and exercise can greatly affect your energy level, they aren't the only culprits. Fatigue can be a symptom of anemia, allergies, depression, anxiety, heart disease, fibromyalgia, rheumatoid arthritis, sleep apnea, Type 2 diabetes, hypothyroidism and many more conditions, reports WebMD. So if you are still exhausted even though you are exercising regularly, eating a healthy diet, and taking steps to improve the quality of your sleep, it might be time to check in with your doctor to find out if other health issues are the cause.
