A cold is a contagious viral disease which infects your mucus membranes. Because it is a virus, it cannot be sweat from the body. Rather, your body will create antibodies to fight it off. Sweating in a hot bath or by drinking hot fluids can help reduce swelling of the membranes, and aid you in expelling excess mucus and toxins from your system. When your body is free of toxins, your immunity from disease is stronger.
Draw a hot bath and add 10 drops of lavender or rosemary essential oil. Lavender and rosemary have anti-bacterial and cleansing properties and will aid the healing process. The water should be hot enough to cause a sweat, but not so hot that it scalds your skin. Soak in the tub and wash your skin with a loofah or rough washcloth to remove dead skin cells. Keeping your pores clean will help your body to sweat more effectively.
Sweat in a sauna for ten or fifteen minutes. If desired, add a few drops of eucalyptus oil to a wet cloth into the sauna. Breathe through the cloth a few times. Eucalyptus helps soothe sore throats and coughing. It will also help your body get rid of excess mucus. Because colds are contagious, use the sauna alone. After you’re done, drink water to replenish lost fluids.
Drink hot teas. A simple herbal tea, like chamomile or green, with added honey and lemon will raise your body temperature and cause you to sweat. Drink hot tea throughout the course of your cold. Lemon gives you a good dose of vitamin C, excellent for boosting your body's immunity. Another option is hot water with lemon and honey. This is an excellent cleansing tonic, and besides raising your body temperature, it will help to break up excess mucus.
Bundle up. Put on some extra warm clothing, including a warm hat and you will definitely sweat. Most colds are caused by rhinoviruses, which replicate more slowly at higher temperatures. So heating up your body temperature will slow the growth of the virus, giving your body a greater chance to fight the cold off quickly.
If you have a fever, it's not a good idea to make yourself sweat. Fevers cause your body to be dehydrated and sweating can make it worse. If you have the flu or pneumonia, stay in bed and keep your body cool. Do not exercise during a cold. Yes, you will sweat, but it will tax your body instead of rejuvenating it.
