Does Drinking Salt Water Actually Help Relieve Headaches?

Dealing with headaches and migraines can be miserable. When desperate for relief, some people try unproven remedies like drinking salt water. But does ingesting salt water actually help get rid of headaches? Let's examine the evidence behind this home remedy.

The Theory Behind Salt Water for Headaches

The basic rationale for drinking salt water is that it may help replenish fluids and electrolytes, potentially alleviating factors that can contribute to headaches like dehydration and electrolyte imbalance.

Many people turn to salt water as a quick and inexpensive remedy when experiencing a headache. Proponents claim that sipping small amounts of salty water provides fast relief by restoring hydration and sodium levels.

But while dehydration and electrolyte imbalance can trigger headaches, there is little scientific evidence that salt water intake provides meaningful or consistent relief for most headache sufferers.

Potential Risks of Drinking Salt Water

Before utilizing any do-it-yourself remedy like salt water, it's important to understand the potential risks and side effects:

Hypernatremia

Consuming too much sodium from salt water can potentially lead to hypernatremia, or high sodium levels in the blood. This can cause water to shift out of cells, leading to dehydration at the cellular level.

High Blood Pressure

Ingesting excess sodium frequently through salt water can increase blood pressure over time for those with hypertension or who are predisposed.

Fluid Imbalance

Overhydrating by drinking large amounts of salt water at once can disturb electrolyte balance and flush out other important minerals like potassium and magnesium.

Nausea and Vomiting

Drinking highly concentrated salt water can irritate the digestive tract, resulting in vomiting, diarrhea, and dehydration.

Without medical oversight, the risks generally outweigh any potential benefits of using salt water as a quick fix for headaches.

Limited Research on Salt Water for Headaches

There is very little scientific research specifically analyzing the efficacy of salt water intake on headaches:

• A 1980 study had participants drink concentrated salt water during a migraine attack. Only 25% reported relief, with nausea being a major side effect.
• A 2011 study in rats found that injections of saline could reduce headaches, but this has not been replicated in humans.
• Anecdotal reports of drinking small amounts of salt water providing relief are unsubstantiated.

Overall, there is insufficient evidence to recommend salt water as an effective headache remedy. More rigorous controlled studies in humans are needed.

When to Use Caution with Salt Water

While generally not recommended, people still try drinking salt water for headaches. If you choose to attempt it, take these precautions:

• Only use small amounts of salt dissolved in water.
• Avoid if you have hypertension, kidney issues, or congestive heart failure.
• Do not use table salt, which has additives. Opt for high-quality sea salt or Himalayan salt.
• Stop immediately if you experience nausea, vomiting, bloating or increased thirst.
• Do not use consistently or frequently without medical approval.

Drinking salt water is generally not advisable for children or pregnant women due to greater risks of excessive sodium intake.

More Effective, Safer Ways to Relieve Headaches

While salt water is an unproven remedy, there are many evidence-based strategies to effectively and safely relieve headaches:

Hydrate with Water

Drinking plenty of regular water can help headaches caused by dehydration. Aim for the recommended daily intake of around 2 liters for women and 3 liters for men.

Manage Electrolytes

Consuming electrolyte beverages with sodium and potassium or taking a supplement can stabilize electrolyte levels without excess salt intake.

Limit Caffeine

Consuming too much caffeine can trigger headaches. Limit to 200-400mg daily and hydrate to counteract its diuretic effects.

Apply Cold Therapy

Applying an ice pack or cold compress to the head and neck can reduce inflammation that contributes to headaches.

Use Essential Oils

Soothing essential oils like peppermint, lavender and eucalyptus can relieve headache symptoms when inhaled, applied topically or used for massage..

Take Anti-Inflammatories

Over-the-counter NSAIDs like ibuprofen, naproxen and aspirin can effectively combat the inflammation behind many headaches when used wisely.

Rest in a Dark Room

Light and sound sensitivity is common with headaches. Resting in a cool, dark, quiet room allows recovery.

Manage Stress

Chronic stress and tension often manifest as headaches. Relaxation techniques like meditation, deep breathing, yoga, and therapeutic massage help reduce headache triggers.

Lifestyle Changes to Prevent Headaches

Making certain lifestyle adjustments can also help minimize headache frequency and severity:

Improve Posture

Poor posture puts strain on the neck and upper back muscles, potentially causing headaches. Fix areas of misalignment and practice maintaining proper posture.

Increase Physical Activity

Exercise helps reduce inflammation and improves oxygen and nutrient flow to the brain. Aim for at least 30 minutes per day of light to moderate activity.

Modify Your Diet

Eat regular meals with adequate protein, complex carbs, fruits, vegetables, and healthy fats. Stay hydrated and limit foods that may trigger headaches like processed meats, aged cheeses, and artificial sweeteners.

Get Adequate Sleep

Insufficient or poor quality sleep can make headaches worse. Adults should aim for 7-9 hours nightly for optimal health.

Manage Chronic Conditions

Effectively treating conditions like high blood pressure, hypothyroidism, and chronic sinusitis can reduce headache occurrence.

Limit Alcohol

Consuming more than 1-2 alcoholic drinks per day increases risk for headaches. Abstain or moderate intake.

When to See a Doctor for Headaches

Consult a physician promptly if you experience:

• Sudden, severe headache onset
• Headaches after a head injury
• Persistent headache following illness
• Worsening frequency or severity of headaches
• Headaches that disrupt work, school or activities
• Vision changes, numbness, weakness, or speech problems
• Headaches that do not respond to treatment

Seeking medical care can help diagnose and properly manage chronic headache disorders like migraines.

The Bottom Line

There is very little scientific evidence showing that drinking salt water consistently and effectively relieves headaches. Consuming excessive amounts of sodium via salt water can also have negative health impacts. While staying well hydrated and maintaining electrolyte balance is important, discuss other safer, proven treatment options with your doctor to find headache relief.
