Maintaining a healthy lifestyle is just as important for adults as it is for children. It's never too late to begin practicing healthy lifestyle habits, like eating a well-balanced diet, getting plenty of exercise, trying to get a good night's sleep, and avoiding harmful substances. Along with regular doctor's visits and being aware of changes in your body's health, these steps can go a long way towards preventing many common diseases and ailments. The flu vaccine is the best protection against the flu. If you get the flu vaccine, you are 60% less likely to need treatment for the flu by a healthcare provider. Getting the vaccine has been shown to offer substantial other benefits including reducing illness, antibiotic use, time lost from work, hospitalizations, and deaths.
