Healthy lifestyle
Today healthy lifestyle is becoming more and more popular both with the
old and the young. People have become more health-conscious. They say that the
greatest wealth is health. And it’s so true. The healthier we are, the better we feel.
The better we feel, the longer we live.
Keeping fit and going in for sports is also important for our health. Lack of
exercise in our life is a serious problem. In big cities people spend hours sitting in
front of computers, TV-sets and other gadgets. We walk less because we mainly
use cars and public transport. We certainly don’t have to be professional
sportsmen, but we should visit fitness clubs, go jogging, walk much, swim, go
cycling or roller-skating or just dance. Doctors say that regular moderate physical
activity is necessary for our body because it protects us from strokes and heart
diseases, flue and obesity.
We must understand the harm of bad habits for our health. Smoking, drinking or
taking drugs mean serious illnesses and even death from lung cancer or liver
diseases, for instance. Cigarettes kill about 3 million heavy-smokers every year.
Drug addicts die very young. So I think there is no place for bad habits in a healthy
way of life.
Taking a proper rest and getting enough sleep, from 8 to 10 hours daily, are
also great healthy habits. Sleep is the food for our brain and the rest for our
muscles. Moreover we should avoid getting nervous or worried for no reason.
Healthy way of life concerns our body, mind and soul. Healthy people live longer,
they are more successful and they enjoy their life. I believe that it’s not difficult at
all to follow these simple rules, and they are worth it.
