Dry air can particularly worsen a dry, irritating cough, so getting an air humidifier can be really useful! Alternatively, you can place a bowl of water on your radiator so that as it warms it releases moisture into the air. Just be careful that your home doesn’t get too humid, as this could cause damp and mould which aren't good for a cough either!
Hi Lydia you’ll never have AMONIA because it’s what you clean floors with but people tent to confuse it, as you did with NEUMONÍA. I also have a cough and bought at WALMART a ginger tea made in Australia which seems to be stronger than others when you don’t have ginger root handy. So I added honey. Always part of our staples and added lemon juice, always also part of our staple and drank tea hot after I let it steep in covered cup and I’m getting better. It beats taking meds that have horrible side effects.
