General Events:
World No Tobacco Day
May 31, 2015 in the World
The World No Tobacco Day is observed on May 31, 2015. It is a day to encourage a 24-hour period of abstinence from all forms of tobacco consumption across the globe and to draw attention to the widespread prevalence of tobacco use and to the negative health effects. The day is celebrated annually.
The member states of the World Health Organization (WHO) created World No Tobacco Day in 1987. Each year, the WHO selects a theme for the day in order to create a more unified global message for WNTD. This theme then becomes the central component of the WHO’s tobacco-related agenda for the following year.
Groups around the world – from local clubs to city councils to national governments – are encouraged by the WHO to organize events each year to help communities celebrate World No Tobacco Day in their own way at the local level.
Past events have included letter writing campaigns to government officials and local newspapers, marches, public debates, local and national publicity campaigns, anti-tobacco activist meetings, educational programming, and public art. In addition, many governments use WNTD as the start date for implementing new smoking bans and tobacco control efforts.

National Save Your Hearing Day
May 31, 2015 in the USA
Each May 31 celebrates National Save Your Hearing Day.   On this day, it is important to take some time to learn about ways to protect your hearing and that of your family.   Our hearing is vital and there are ways that hearing loss can be avoidable.
It is estimated that half of the cases of hearing impairment and deafness are preventable.  There are many preventative strategies that are effective including: immunization against rubella to reduce congenital infections, immunization against H. influenza and S. pneumonia to reduce cases of middle ear infections, and avoiding or protecting against excessive noise exposure.
Finding and utilizing the available education on the perils of hazardous noise exposure will increase your awareness in the important need of hearing protection.
