2. Anemia 
When I was in college, there was a time period where I was extremely tired no matter how much rest I had. It was very frustrating and I couldn’t figure out why. I tried exercise and sleeping early but nothing helped. I later discovered that I was anemic and needed to increase my iron levels to solve the issue. Anemia occurs when the body has lower-than-normal levels of red blood cells. Anemia is a result of a low supply of oxygen reaching cells and tissues throughout the body.
Suffering from anemia will make you feel lackluster regardless of the amount of sleep you get. Anemia is connected to low iron levels within the blood as well as low levels of vitamin B12 and folate. Anemia can easily be fixed by eating foods that are rich in iron, vitamin B12 and folate. Eating foods loaded with vitamin C, such as citrus fruits and green leafy vegetables with high levels of iron and folate will help with iron absorption.
