Solution
- Many people are tired and do not have the energy to perform day-to-day activities. They are tired and tend to sleep in the classroom or workplace. Though this can be due to various reasons, the common reason for this condition is Anaemia.
- People who are Anaemic have less number of Red blood cells in their blood.
- The Red blood cells have hemoglobin which carries oxygen to all the cells of the body.
- People who are Anaemic will have less oxygen supply to all the cells of the body.
- Energy production in the cells is less and they feel tired and sleepy always. This is due to the diet. Prevention: Eat food rich in Iron.
