Many of us are familiar with recommendations for maintaining heart, skin, and digestive health, as these topics are frequently covered in media. However, we rarely hear or read about how to take care of our voice—even though it's our primary tool for communication.
In this article, we aim to highlight the most important recommendations for keeping the vocal cords in good condition.
1. Vocal Rest
Avoiding vocal strain is the first and most important recommendation. Many of us have experienced hoarseness or voice loss after yelling, so it’s crucial to avoid shouting—especially when emotionally agitated or stressed.
But shouting isn’t the only thing that stresses the voice. Any attempt to alter your natural voice tone is also straining. Examples include children mimicking adult voices, men imitating women’s voices, whispering, or mimicking others. Talking in noisy environments, like concerts, weddings, or sports events, is especially harmful because people tend to raise their voices or shout without realizing it.
Those who use the phone for long periods should be careful as well. On the phone, we rely on our voice to express emotions normally conveyed through body language. Many people also change their natural voice when speaking on the phone, which can strain the vocal cords.
2. Avoid Irritants
Irritants can be gases or foods. Gases and strong odors travel through the respiratory tract and hit the vocal cords directly, causing irritation. The biggest offender here is smoking, whose negative impact on the larynx deserves an article of its own.
Other irritants include environmental pollutants, cleaning chemicals, dust, and even some perfumes. As for irritating foods, they include spicy foods, cold drinks, and alcohol.
3. Hydration
Drinking plenty of fluids—especially water—is one of the most vital recommendations for vocal health. A person should drink about 3 liters of fluids per day, with increased intake during hot days or heavy physical activity.
The body secretes a protective oily substance to lubricate the vocal cords, and dehydration reduces this secretion. Note that certain fluids actually dry out the vocal cords, such as tea, coffee, alcohol, and cola—so these should be limited.
Dry air also harms the voice, so it's advised to humidify your environment by using a humidifier or placing a bowl of water on a heater—especially in homes and offices.
4. Additional Tips
- Warm up your voice before using it for long periods (e.g., humming softly before singing or speaking).
- Avoid unnecessary throat clearing. (This includes the mild coughing people do to clear mucus from their throats.)
- If you suffer from acid reflux or heartburn, avoid triggers like eating large meals before bedtime or consuming fatty foods, as acid reflux can damage the vocal cords.
- When experiencing hoarseness or voice loss—such as during a cold or chest infection—avoid talking or even whispering as much as possible.
- If hoarseness lasts more than three weeks, consult a doctor immediately, as it may indicate a more serious condition. Early diagnosis is the key to successful treatment—even for serious conditions like vocal cord tumors.
