Keep your throat lubricated as much as possible. Drink lots of water, and get in the habit of always having a water bottle nearby.
Breathe steam!- use a humidifier or vaporizer, especially during the winter months, and especially at night.
This can work miracles for both treatment and prevention of problems.
If you do feel like you’re losing your voice, try wrapping a hot towel, or heating pad around your neck, while sipping ice water. Do this for 15-30 minutes several times a day if you can. Even once will help enormously. The idea is that the heat relaxes the muscles, while the cold reduces the inflammation on your vocal folds.
Drink hot lemon juice or tea with honey. (Throat Coat tea is available at most drug stores, and
is a nice treat!)
Avoid clearing your throat, and whispering .Both are very hard on vocal folds.
Gargle with warm salt water.
If you suffer from allergies, stay on top of them. Once they grab hold, you are wide open for
catching a cold, and losing your voice.
