Wash your hands: it seems there is no simpler and more effective rules to protect their own and others health.
During the day, our hands are in contact with numerous objects full of microorganisms (banknotes, to support public transport, to the door handles, to the gym gear, snacks on the bar or the electronic tools buttons). Some bacteria have also developed a strong resistance to antibiotics and it is therefore important to prevent infection by washing your hands thoroughly, especially if the person has a weakened immune system.
When it comes to personal hygiene, it is not only important to respect the indications on the appropriate time to wash their hands, but also those related to the proper washing and cleansing technique. A fast rinse, in fact, is not sufficient to eliminate the problem.
