Technology And Physical Activity

Today's world is known as a world of Information Technology (IT). Information Technology and advanced technology has made human life very convenient. Without leaving the house all requirements can be ordered and home delivered, using technology. Appliances in the house can be switched on or off and operated using the mobile.

Advanced technology has brought about a comfortable lifestyle. In fact, it has made many things easily possible. But then, the question arises whether this advanced technology is reducing our activeness?

Although, modern technology has improved the work power, it has inversely reduced the physical work capacity of individuals. This has resulted in many diseases attacking the human body.

Before such advancement of technology, a family used leisure time to be in the company of each other and enjoy playing some games. During vacations, students enjoyed skipping, swinging on trees and so on. But today, when children get together during vacations or when the family gets together, instead of playing, children spend time glued to mobiles, tabs or computers.

Ideally in a day, a minimum of one hour should be set aside to participate in some form of physical activity. But most studies indicate that maximum students are physically inactive.
