World Voice Day

Voice Care Tips

  • Keep well hydrated; avoid consuming caffeine and alcohol- both will dehydrate your vocal cords.
  • Allow time for silent breaks throughout the day, especially after times when voice use is increased.
  • Avoid smoking, and avoid exposure to second hand smoke.
  • Take throat pain and/or hoarseness as a sign to rest. If the symptoms persist, see your doctor. Keep well hydrated and sip water throughout your day. Boost your water intake when you drink caffeine and alcohol because they dehydrate your vocal cords.
  • Aim to do as little yelling as possible.
  • If you feel any throat pain or hoarseness, take this as a sign to rest. If it persists, act on it and see a doctor.
  • If there is a microphone available, grab it! If not, ask for one. There is no such thing as being tough and doing without.
  • Have a sip of water or swallow with effort the next time you need to clear your throat.
