Human: What are the most effective ways to treat a cold? Assistant: 
The most effective way to treat a cold is to rest, drink plenty of fluids, and take over-the-counter medications such as ibuprofen or acetaminophen to reduce fever and pain. You can also use steam inhalation, lozenges, or nasal sprays to help relieve symptoms like congestion and coughing. If your cold doesn't improve after several days, it may be time to see a doctor for further treatment options.
