That feeling will last beyond the time IV liquids stay in your body. You will benefit from feeling hydrated and refreshed long after the actual IV fluids leave your body.

However, one study reported slower restoration of blood pressure [1]. In the case of respiratory syncytial virus (RSV), the most common cause of bronchiolitis, hypertonic saline is known to reduce infection and inflammation in cultured human respiratory epithelial cells. Hypertonic saline is already adopted prophylactically to manage cases of influenza, bronchiolitis, rhinitis, sinusitis, and other respiratory disorders. A spray is sufficient for the upper airways, while a nebulizer is needed to reach the lungs. These interventions can minimize the symptoms of such diseases, but the mechanisms underlying their effects are poorly understood. Fun times are had trying to figure out how much extra sodium we are giving with any of the first three items. This is important as you begin to transition from the big guns (hypertonic), to regular saline, and then to oral salt tabs.

Normal Saline is widely used in hospitals, clinics, and emergency medical services for intravenous infusion, wound care, and eye irrigation. You should consult your doctor before adding more sodium chloride to your diet. Most people exceed the recommended amount, but people who drink excessive amounts of water, have persistent diarrhea, or participate in long endurance events may have sodium deficiency. In more severe cases, a healthcare professional may need to provide intravenous (IV) saline solution to restore hydration and electrolytes. An isotonic solution contains an electrolyte balance similar to plasma in the bloodstream. When an isotonic solution is administered, the fluid volume of the patient is increased without a fluid shift, meaning there will be no osmosis.

Even if you drink enough water to stay hydrated each day, illness can strike any time. Vomiting and diarrhea can easily lead to dehydration and make it difficult for you to rehydrate if you can’t keep water down. Cilia are small hair-like structures that help humidify air going to your lungs, trap bacteria to keep them from entering the cells, and aid your sense of smell. By keeping cilia healthy, saline sprays may help treat rhinitis and sinusitis, studies show.

Some studies show that a saline solution restores moisture to dry nasal passages and sinuses, and curbs inflammation of mucous membranes. Too much salt can lead to bigger health concerns like high blood pressure, heart disease, and kidney disease. Lowering your salt intake while increasing how much potassium you get can help lower your risk for those conditions. Overusing decongestant nasal sprays can lead to rebound congestion in which your nasal congestion gets worse rather than better.
