Does Vaping Affect Cardio?
Health Guides
If you train regularly and you vape, the question of how vaping affects your cardiovascular performance is a legitimate one. The evidence is nuanced: vaping is significantly less damaging to cardio performance than smoking but nicotine does have measurable effects on the cardiovascular system that are worth understanding.

The short answer
Does Vaping Affect Cardio Performance?
Nuanced answer
Yes — through nicotine's cardiovascular effects, but significantly less than smoking
Vaping affects cardiovascular exercise performance primarily through nicotine's stimulant and vasoconstrictive effects. Nicotine raises resting heart rate and blood pressure, reduces blood flow to peripheral muscle tissue and increases cardiovascular demand at rest — all of which have implications for exercise performance and recovery. However vaping does not produce carbon monoxide, which is one of the primary mechanisms through which smoking dramatically impairs oxygen delivery during exercise. The impact of vaping on cardio is real but substantially less than smoking, and the evidence does not support the claim that vaping prevents people from performing cardiovascular exercise effectively.
This is not medical advice. If you have cardiovascular health concerns, please speak to your GP before beginning or continuing an exercise programme.
How nicotine affects exercise
The Specific Effects of Nicotine on Cardiovascular Performance
Nicotine Raises Resting Heart Rate
Nicotine stimulates the sympathetic nervous system, triggering adrenaline release and raising resting heart rate. The typical increase is 10 to 20 beats per minute above a true resting baseline. For a cardiovascular athlete, a chronically elevated resting heart rate means less capacity to increase heart rate during exercise before reaching maximum heart rate. This effectively compresses the useful training zone and may limit the intensity that can be sustained in aerobic exercise sessions.
Elevated Blood Pressure Under Exercise Load
Nicotine raises blood pressure through both its effect on heart rate and its vasoconstrictive narrowing of blood vessels. During exercise, when blood pressure naturally rises significantly, the additional nicotine-driven baseline elevation means the cardiovascular system is working harder for the same exercise output. This increases cardiovascular strain during high-intensity sessions and may limit sustainable exercise duration at higher intensities.
Vasoconstriction and Oxygen Delivery to Muscle
Nicotine narrows blood vessels throughout the body, including those supplying oxygen and nutrients to working muscle tissue. During exercise, where adequate blood flow to active muscles is critical for performance and recovery, this vasoconstrictive effect can reduce the oxygen available to the muscles, limiting aerobic capacity and contributing to faster onset of fatigue. This is a meaningful effect on performance, particularly in endurance sports.
Impaired Post-Exercise Recovery
The recovery period after exercise depends on adequate blood flow to clear metabolic waste products including lactate from muscle tissue and deliver oxygen and nutrients needed for repair. Nicotine's vasoconstrictive effect during the recovery period may slow this process, potentially contributing to longer recovery times, greater muscle soreness and reduced training frequency over time. This is an area where reducing nicotine intake around training sessions is likely to have a measurable benefit.
Vaping vs Smoking — the Carbon Monoxide Difference
Carbon monoxide from cigarette smoke binds to haemoglobin with far greater affinity than oxygen, directly reducing the blood's oxygen-carrying capacity. This is one of the most significant mechanisms through which smoking impairs cardio performance. Smokers have measurably reduced VO2 max — their maximum oxygen uptake capacity — compared to non-smokers. Vaping does not produce carbon monoxide, which means this particular mechanism of cardio impairment is absent in vapers. This is the primary reason vaping's impact on cardio is considerably less than smoking's.
"We have quite a few customers who are serious about training and ask about this. The honest message is: nicotine does affect your cardiovascular system and there are measurable implications for performance, but you are not in the same position as a smoker."

What Vapers Who Train Should Know
01
Avoid vaping immediately before training
The acute cardiovascular effects of nicotine — raised heart rate, elevated blood pressure, vasoconstriction — peak within minutes of vaping and persist for up to 30 minutes. Vaping immediately before a cardio session adds cardiovascular strain at the point of highest demand. A gap of at least 30 to 60 minutes between vaping and training is a sensible rule of thumb.
02
Consider nicotine-free options around training
Using nicotine-free e-liquid for sessions around training windows eliminates the acute cardiovascular effects of nicotine while maintaining the vaping habit. This is a practical compromise that many training vapers find effective.
03
Monitor your resting heart rate
Tracking resting heart rate over time provides direct evidence of nicotine's effect on your cardiovascular baseline. Many wearable devices measure this. If resting heart rate drops measurably when you reduce or pause nicotine use, the relationship is clear.
04
Reducing nicotine improves cardio markers
The vasoconstrictive and heart rate effects of nicotine are dose-dependent. Reducing nicotine strength reduces these effects proportionally. Stepping down from 20mg to 10mg to 6mg progressively improves the cardiovascular picture even if full cessation is not the goal.
