It is usually normal to feel cold after eating or drinking hot water. When you eat, more blood goes to your stomach for digestion, so the rest of your body may feel cooler for a while. Hot drinks can also make you sweat a little, and that cooling makes you feel cold. If it happens often with weakness or dizziness, get it checked.

You can safely breastfeed even if you have a cold and a cough. The infection does not pass through breast milk. Instead, your milk gives your baby protective antibodies. Rest, drink plenty of warm fluids, do steam inhalation, and use a saline nasal spray. If your condition persists, consult a doctor.
