Drinking plenty of clear liquids, inhaling steam or using a humidifier, using a saline spray or salt water rinse, and gargling with warm salt water are effective remedies for the common cold, according to WebMD. Staying warm and getting extra rest also help the immune system fight off cold germs.
Drinking hot liquids, such as herbal tea with honey, helps prevent dehydration while soothing the throat and relieving nasal congestion, reports WebMD. If the cold is causing congestion, sleeping with an extra pillow underneath the head helps the patient breathe easier by relieving the congested nasal passages. Taking a warm, steamy shower is an excellent way to moisturize the nasal passages and soothe achy muscles.
