Reasons for fatigue

Reasons for fatigue

Are you constantly tired, fighting to stay focused or even to keep your eyes open? This is a common symptom of cold or the flu, but when this lack of energy persists even when you are not sick, it may be time to change some things about your lifestyle to keep you energized both mentally and physically. So what is making you extra tired? And how can you regain your full strength?

What are the main reasons for fatigue?


Lack of exercise

You may be thinking “that doesn’t make sense, how can exercise make me less tired?” It can! Exercise, even for a mere 20 minutes three days a week, can boost your overall energy levels. This is because practicing a regular physical activity helps your cardiovascular system, helps in delivering oxygen and nutrients to your tissues and organs more efficiently, and increases your overall endurance. So, next time you feel tired, instead of sinking into your couch or bed, go for a light walk.


Not getting enough water can slow down your blood’s delivery of oxygen and nutrients to your muscles and organs, which contributes to the feeling of tiredness, according to experts.

Anemia/Not getting enough iron

Iron deficiency can make you feel weak, lazy, drowsy, and unable to concentrate. Eating foods rich in iron such as beef, beans, eggs, green vegetables, and nuts, can help make you feel more vital.

Skipping breakfast

When you sleep, your body uses the nutrients you provided it with to keep your organs functioning. That’s why, when you wake up, you should replenish your body with a new supply of nutrients which you get from breakfast. Skip breakfast, and you will feel lazy.

Eating junk food

Junk food is laden with sugars and simple carbohydrates increase blood sugar and can cause blood sugar spikes. Repetitive blood sugar spikes followed by drops can cause exhaustion. A good alternative for junk food is eating foods that are full of protein along with whole grains.
