Practice diaphragmatic breathing. This is the most important tip, as proper breathing technique will help you to support your voice and avoid straining it. To practice diaphragmatic breathing, sit up straight and place one hand on your stomach and the other hand on your chest. As you inhale, feel your stomach rise and your chest stay still. As you exhale, feel your stomach fall and your chest move inward. Repeat this exercise for several minutes, until you are comfortable with the technique.
Warm up your voice. Before you scream, it is important to warm up your voice. This will help to loosen up your vocal cords and make them less susceptible to injury. There are many different ways to warm up your voice, such as singing, humming, or doing vocal exercises.
Don't scream for too long. If you scream for too long, you are more likely to strain your voice. Try to limit your screaming to short bursts of no more than a few seconds at a time.
Drink plenty of fluids. Staying hydrated is important for your vocal health. Drinking plenty of water will help to keep your vocal cords lubricated and prevent them from drying out.
Avoid smoking and alcohol. Smoking and alcohol can both dry out your vocal cords and make them more susceptible to injury. If you want to protect your voice, it is best to avoid these substances.
See a doctor if you experience pain. If you experience any pain in your throat or voice after screaming, it is important to see a doctor. This could be a sign of a vocal injury, which may require treatment.
