That’s according to a study by Spain’s Ear, Nose and Throat Association (SEORL), who found teachers to be the most afflicted by vocal cord upsets.
Nearly 23 percent of teachers suffer some form of voice disruption, making it their second reason for taking a day off work.
Ear, nose and throat doctors have decided to offer free check-ups on April 16th, World Voice Day, to make people aware of why they suffer voice problems.
Exercise, diet, sleep, drinking enough water and not smoking are all said to be key to keeping a healthy voice.
“Our voice is our main means of communication, it's part of our image and in many cases it's an important work tool,” SEORL president Secundino Fernández told 20minutos.
“A 'sick' voice can have a negative effect on our quality of life, our relationships and affect our professional performance," he added.
Fernandez recommends using propolis, a resinous mixture that honey bees collect, and not regular cough sweets.
