have to drink plenty of water or
fruit juices and have complete rest.

When you have influenza, you have to take

drink plenty of water and fruit juice. If you
have sore throat, gargle with warm salted
water.

General Risk Factors of Disease
Here are some of the factors that greatly affect your health:
 Heredity - genes play an important role in determining the life span of an
individual. Some people may inherit factors that can affect the metabolic rate of a
person such as an underactive thyroid gland. An under thyroid gland can
decrease metabolic rate that may result in obesity. Other people may inherit factors
that affect their cholesterol level. Cholesterol is a fatty substance that is vital for
good health but increased levels of cholesterol may lead to heart disease.

8. General Risk Factors of Disease
Here are some of the factors that greatly affect your health:
 Environment – in order to achieve good health, one must obtain safe water, clean
air, healthy work places, safe houses, secured communities, and paved roads.
 Lifestyle – it is a typical way of life that can affect one’s health and life expectancy.
Imbalanced diet or poor eating habits may cause chronic diseases such as diabetes
