Yoga has a therapeutic affect and also helps to reduce your stress level. In big cities people spend hours sitting in front of
computers, TV-sets and other gadgets. We walk less because we use cars and public transport. We should visit fitness clubs,
go jogging, walk much, swim, go cycling or roller-skating or just dance. Doctors say that regular physical activity is
necessary for our body.
Sleeping right, having a positive outlook about life and having a balanced life are also the necessary components of a
healthy lifestyle. If you go without sleep for a period of time, every area of your life will be ultimately affected. 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.
We must understand the harm of bad habits for our health. Smoking, drinking or taking drugs mean serious illnesses.
Cigarettes kill about three million heavy-smokers every year.
