1. Dehydration

Being even slightly dehydrated can take a toll on energy levels. Dehydration causes a reduction in blood volume which makes the blood thicker. It requires the heart to work harder. Dehydration reduces the speed at which oxygen and nutrients reach the muscles and organs in the body. To avoid being dehydrated, consume eight 8-ounce glasses of water a day, which equals about 2 liters or half a gallon.

Iron Consumption

Too much or too little iron in the body can leave you feeling sluggish, weak, and unable to focus. Low iron leads to poorly formed red blood cells that deprive the body of energy. However, too much iron can wear you down as well. The body uses vitamins, minerals and energy to clear your system of the excess, leaving you with little iron in the body. The body needs 10 mg of iron daily.


Striving to do everything is impossible and it can take a toll on your body. Stress hormone cortisol level is highest in the morning and dips down at night to help maintain a normal rhythm. When the body is constantly alert, the cortisol levels may not go down at night and instead is relatively high. When the cortisol level is high at night the body is constantly alert and cause sleep to be disrupt. To avoid the abnormal fluctuation of cortisol level you should meditate, relax, exercise, and try to not work late in the night.


As mentioned above, exercising can help reduce stress levels. It is mandatory that a person gets 30-45 minutes of exercise everyday. A stressful day at work increases cortisol and blood glucose levels. You must release the tension and energy by exercising. When the tension and energy isn’t released, sleep gets disrupted.

Junk Food

Whether you want to believe it or not, junk food leaves you sluggish and tired throughout the day. Sugar may be a quick way to boost energy, but does the opposite in the long run. Junk food increases blood sugar which causes fatigue over the course of the day. Avoid eating sugary products and eat a balanced diet.
