Hissing sounds from the chest when lying on your left side could be due to excess mucus or fluid in the airways. To address this, try sleeping with your upper body slightly elevated using pillows. You can also consider using a humidifier in your bedroom to help keep the air moist and ease breathing. If the issue persists or worsens, consult a healthcare professional for further evaluation and treatment.
