For symptoms of nasal congestion due to a cold, you can relieve nasal breathing by massaging specific points such as the Yingxiang acupoints on both sides, the Zusanli, and the mandibular points, all of which have certain effects and therapeutic benefits. At the same time, it is important to maintain the cleanliness of indoor air, drink plenty of water, avoid exposure to dust, smoke, and other irritating chemicals, and eat more fruits and vegetables rich in vitamin C to promote the repair of tissue mucosa and relieve symptoms of nasal congestion. Measuring your body temperature twice a day can also help with the recovery from the illness.
