Vocal Tips with Cherish Tuttle | CAFFEINE

Caffeine is in a lot of drinks and a very common additive in several products you get from the store or the gas station. I decided to eliminate caffeine from my life for a month just to see what happens and I did have a positive outcome.

Caffeine is considered a dehydrating agent and can dehydrate your voice. Vocal cords need hydration and somewhat of a mucus or lubrication to work and function well. If your vocal cords are dehydrated it can limit your range and your ability to sing.

With no more caffeine in my life along with a healthy meal plan, I have noticed my vocal ability has improved and feels better overall. Some may not have the same outcome, but for me this has been very eye opening.

"Voice-related studies of hydration have been concerned with systemic and superficial hydration. Systemic hydration refers to adequate fluid located within body tissues and is predominantly achieved through water intake. Conversely, superficial (or surface) hydration is defined as the hydration of the surface of laryngeal mucosa that keeps the epithelial cells moisturized and lubricated, and is achieved via steam inhalation or increased environmental humidity. Inadequate hydration can adversely affect vocal fold viscoelasticity, oscillation threshold and voice quality, since vocal folds are covered with a thin mucosal surface layer that has biomechanical and protective properties.

Human studies have demonstrated that both systemic and superficial dehydration adversely affects phonation. Reduced hydration over a fasting period greatly affected maximum phonation time (MPT) and perceived phonatory effort (PPE) in males and females.30,31 Inadequate hydration also negatively impacted acoustic, perceptual and aerodynamic measures in professional singers following a 2-hour rehearsal."
