Being healthy is a big part of being happy. A healthy lifestyle simply means that the way you are day to day, makes you feel physically and mentally fit and well.
What is a healthy lifestyle? Balance is the key, it's about what you put into your body and also how you burn that energy off. Food is burned in our bodies to create energy. If we don't use it, we get fat - simple!
If your lifestyle is not a healthy balance - for instance through not exercising, eating too much fatty and sugary foods, drinking alcohol, getting involved in drugs or by keeping worries and problems to yourself - you are more likely to become ill, have trouble concentrating at work or school or be unhappy or depressed. Being active can reduce your stress levels and can give you the time to think clearly.
Your lifestyle has a big affect on how you feel and what you get out of life, both now and in the future. So it's a good idea to find out more about how to live healthily.
There are many other areas of our health we need to think about like sexual health, healthy teeth, drugs, alcohol and generally looking after ourselves.
