Feeling fatigue can affect every area of your life. It's not normal to feel exhausted if you're getting enough sleep. If your overall health is good but you still feel tired all the time, other factors could be at play.

Here are seven reasons why you might not be able to shake that constant feeling of exhaustion.

1. You Skip Workouts When You're Tired
You're tired and decide to skip your workout to save energy. But studies show that regular exercise boosts your endurance and strength, makes your cardiovascular system run more efficiently, and delivers oxygen and nutrients to your body's tissues.

Plus, people who exercise as little as three days a week for 20 minutes reported feeling less fatigued and more energized.

2. You Don't Drink Enough Water
Even minor levels of dehydration can cause energy loss. Not drinking enough water causes dehydration, which causes a reduction in blood volume. This makes your blood thicker and requires your heart to pump less efficiently. In turn, oxygen and nutrients reach your muscles and organs at a slower rate.

It's worth noting that eating fruits and vegetables can increase your fluid intake as well. (And, since September is Fruits & Vegetables: More Matters month, what better time to start adding produce to your diet?) Experts suggest dividing your body weight in half and drinking that number of fluid ounces per day.

3. You're Sitting Too Much
Your desk job may be sapping your energy level because prolonged sitting can slow your metabolism and diminish your overall health. The good news is that short stints of light-intensity walking will combat those feelings of fatigue.

Health experts say you should set an alarm reminder to get up and walk around every hour and stand when you're talking on the phone.

4. You Don't Consume Enough Iron
Studies show that an iron deficiency makes you feel tired because a decreased amount of oxygen is sent to the muscles and cells. There are many foods that increase your iron intake, including lean beef, eggs (with the yolk), dark green leafy vegetables, nuts, peanut butter, kidney beans, tofu and more.

5. You Eat Too Much Junk Food
The negative impact junk food has on our health is well known, including its relationship with fatigue. Foods loaded with sugar and simple carbs cause blood sugar spikes (followed by sharp drops) that cause exhaustion over the course of the day. Eating lean protein and a whole grain at every meal will prevent spikes and falls of blood sugar.

6. You Skip Breakfast
Your body uses what you consumed at dinner the night before to keep your blood and oxygen flowing. That said, you need to refuel in the morning, and when you skip breakfast chances are you're all but guaranteed to start your day sluggish. Breakfast kick-starts your metabolism - especially if it includes protein, whole grains, and healthy fat.

7. Your To-Do List Is Too Long
You'll feel defeated if your list of things to do is never-ending. You'll also notice your energy draining as you try to get everything done to no avail. If you've got a lot on your plate, break your day down into achievable goals and write down approximately how much each task will take. You'll feel empowered by your manageable list, not overwhelmed.
