Why Do I Feel Dizzy After Vaping? Understanding Causes & Prevention

Understanding Dizziness After Vaping

Vaping has become an increasingly popular alternative to smoking cigarettes. Many believe vaping is a safer and healthier option. However, some people report feeling dizzy or lightheaded after vaping. This article will explore the potential causes behind dizziness after vaping and steps you can take to avoid it.

Nicotine's Effects on Blood Pressure and Heart Rate

One of the main reasons vaping can cause dizziness is related to nicotine. Most vaping liquids contain nicotine, though the concentration can vary. Nicotine is a stimulant that can briefly raise your heart rate and blood pressure when vaped. This reaction is similar to what smokers experience when smoking a cigarette.

The stimulant effect of nicotine causes your heart to work harder and pump faster. It also constricts blood vessels and can reduce blood flow. This combination of a faster heartbeat and restricted blood flow can drain blood from your brain, leaving you feeling lightheaded or dizzy.

Dehydration and Low Blood Sugar

Vaping can also lead to dehydration for some people. The propylene glycol and vegetable glycerin used to create vaping clouds pull moisture out of your mouth and throat as you inhale. This can leave you dehydrated. Dehydration drops your blood volume, which reduces blood flow to the brain and can cause dizziness.

Low blood sugar is another potential cause of dizziness after vaping. Nicotine causes your body to release adrenaline, which gives you a burst of energy and temporarily raises blood sugar. When the nicotine wears off, your blood sugar can crash, leaving you feeling shaky and dizzy.

Toxins and Contaminants in Vaping Liquids

Certain toxins and contaminants found in some vaping liquids may also trigger dizziness in sensitive individuals. For example, some flavorings used in e-liquids contain chemicals called acetals. Acetals can cause side effects like dizziness, nausea, and headaches in high concentrations.

Trace amounts of solvents like propylene glycol and vegetable glycerin may remain in vaping liquids improperly mixed or purified. Inhaling these contaminants can irritate your throat and lungs while also causing dizziness or impaired coordination.

Lack of Oxygen to the Brain

Holding in vape hits for too long can also make you feel dizzy. Breathholding decreases oxygen levels in your blood. With less oxygen circulating, your brain gets deprived of oxygen. This triggers a rapid feeling of dizziness and lightheadedness.

The High Nicotine Concentration in Some Vaping Liquids

Another potential cause of dizziness from vaping is the high concentration of nicotine found in some vaping liquids. The level of nicotine in vaping liquids is generally measured in milligrams per milliliter (mg/mL). Many popular prefilled pod systems contain roughly 50 mg/mL of nicotine.

In comparison, one cigarette contains approximately 1015 mg of nicotine. For those not accustomed to high levels of nicotine, vaping liquids with concentrations over 20 mg/mL can cause headaches, nausea, and dizziness.

PG Allergy or Sensitivity

Having an allergy or sensitivity to propylene glycol could also cause dizziness with vaping. Propylene glycol (PG) is one of the main solvents used to create vaping clouds. Some people may have an undiagnosed allergy to PG that triggers symptoms when they vape.

Dizziness, headaches, throat irritation, and shortness of breath are common signs of a PG allergy. Switching to a 100% VG vape juice or nicotine salts may help alleviate this side effect for those with a PG allergy.

Other Potential Causes of Dizziness

While vaping is a common trigger, dizziness can also occur due to medical conditions like:

• Low blood pressure
• Dehydration
• Anemia
• Low blood sugar
• Inner ear problems
• Migraines
• Seizures
• Heart problems
• Stroke
• Vestibular neuritis
• Medication side effects

If you experience chronic dizziness, it's important to speak with your doctor to rule out an underlying medical issue. Acute dizziness after vaping likely indicates sensitivity to vaping products versus a serious health problem.

Tips to Prevent Dizziness When Vaping

If you enjoy vaping but want to avoid dizziness, here are some useful tips to try:

Stay Hydrated

Drink plenty of water before, during, and after vaping to prevent dehydration and dizziness. Dehydration exacerbates vaping's effects on blood pressure and circulation.

Avoid Nicotine Overload

Only vape liquids with a nicotine concentration your body can tolerate without adverse effects. Avoid high nicotine salts and gradual decrease nicotine levels over time.

Take Slow, Gentle Hits

Inhale vape hits slowly and avoid holding hits in your lungs. Long breathholding depletes oxygen levels and makes you dizzy.

Check Vape Juice Ingredients

Avoid vape juices with high concentrations of acetyls, solvents, and other contaminants that can cause dizziness. Read labels carefully.

Consider Non-Nicotine Vaping

Try transitioning to 0 mg non-nicotine vaping liquids. This removes nicotine stimulation as a potential cause of dizziness.

Avoid Vaping on an Empty Stomach

Have a snack before vaping to maintain stable blood sugar levels. This prevents nicotine-induced crashes.

Talk to Your Doctor

Consult your physician about medications and treatment options if dizziness persists despite lifestyle changes.

The Bottom Line

Dizziness while vaping is common yet preventable. Pay attention to nicotine levels, vape juice ingredients, and your vaping habits. Stay hydrated and avoid excessive nicotine intake. See a doctor if symptoms persist despite taking precautions. With some tweaks, you can vape without enduring dizzy side effects.
