Vibrations or any other intense sensations may indicate that the practice is too intense or that you may have overexerted yourself. It's important to approach pranayama techniques gradually and with caution, especially if you're new to them or have any underlying health conditions. Start with shorter durations, such as 5 minutes, and gradually increase over time as your body adapts. Listen to your body and decrease or stop the practice if you experience discomfort or unusual sensations. If you're experiencing persistent or concerning symptoms, it's best to consult a healthcare professional or a qualified yoga instructor who can assess your situation and provide guidance tailored to your specific needs.
Remember that everyone's body is different, and what may be normal for one person may not be for another. It's crucial to prioritize your safety and listen to your body's signals. If you experience any unusual or persistent symptoms, it's always best to consult with a healthcare professional or an experienced yoga instructor for appropriate guidance and support.
