Unusual fatigue

If you sleep well but for some reason always feel tired, the reason could be as simple as not enough water. The rule of thumb is to have at least two glasses of water every hour, according to WebMD. What’s making you feeling tired may be the fact that your heart is working harder to pump blood to compensate for the loss of volume of blood due to dehydration.

Feeling tired all the time, and maybe drinking a lot of coffee in the afternoon for a quick boost, may also be signs of a serious health problem.
