Question & Answer
Q.1: State any two conditions essential for good health.

Q.2: State any two conditions essential for being free of disease.
Ans : The conditions essential for being free of diseases (i) Taking good food (balanced diet) (ii) Maintaining personal and public hygiene.
Q.3: Are the answers to the above questions necessarily the same or different? Why?
Ans : The answers are not same all the time. Because the meaning of health varies from person to person. For example, good health for a dancer may be being able to stretch his body into difficult but graceful positions. On the other hand, good health for a musician may mean having enough breathing capacity in his/her lungs to control his/her voice. There is one similarity in both the cases. If the conditions essential for good health are maintained, then there are no chances of getting a disease.
Q.4: List any three reasons why you would think that you are sick and ought to see a doctor. If only one of these symptoms were present, would you still go to the doctor? Why or why not?
Ans : When there is a disease, its symptoms and signs appear. These symptoms may be headache, cough, loose-motions, wound with pus, etc. These symptoms indicate disease but do not tell what the disease is. So, it is advisable to go to the doctor to diagnose any signs of a disease on the basis of these symptoms. The doctor will get laboratory tests done, if required for the confirmation of a particular disease.
Q.5: In which of the following case do you think the long-term effects on your health are likely to be most unpleasant?
- if you get jaundice,
- if you get lice,
- if you get acne. Why?
Ans : Lice and acne will not cause long lasting effects on our body. But in case of jaundice, there will be severe long lasting effects. For example: (i) High temperature, headache and joint pains. (ii) Feeling of nausea and vomiting. (iii) Initiating rashes. The patient will suffer from poor health and will recover by taking complete bed rest for sometime.
