Some research suggests that nicotine may negatively affect muscle growth. However, there is other evidence that indicates it could help with athletic performance. Muscle growth, which health experts call hypertrophy, refers to muscle fibers growing in response to damage.
Vaping, particularly when it involves nicotine, can negatively impact muscle growth and overall fitness for several reasons: Reduced Oxygen Delivery: Nicotine constricts blood vessels, which can reduce oxygen delivery to muscles. Adequate oxygen is crucial for muscle performance and recovery.
Your brain continues to grow until age 25. Before then, it's highly sensitive to the effects of e-cigarette chemicals, especially nicotine. It can disrupt your brain growth, with lasting effects on your learning and thinking skills.
Does vaping make you fat or skinny? Neither; Vaping does not directly impact your weight as you cannot consume calories contained within e-liquids or disposable vapes. Although nicotine may suppress your appetite, it is not directly related to making you lose weight.
Indeed, nicotine triggers oxidative stress in the testis, resulting in a global alteration of testis function, with a decrease in testosterone level, lower epididymal sperm number and viability, and increased levels of apoptosis in spermatogonia and spermatocytes [53,54,55,56].
Our results provide a potential mechanism by which habitual tobacco use could decrease muscle mass (i.e., by reducing the rate of muscle protein synthesis and increasing expression of genes associated with impaired muscle maintenance).
Vaping exposes users to fewer toxins and at lower levels than smoking cigarettes. Switching to vaping reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke.
Quitting nicotine products does not mean you will gain weight, although it could. Planning to quit is an important decision to make and so is creating a lifestyle plan after you have completed cessation. The reason people gain weight when quitting is that nicotine suppresses appetite and can impact the metabolic rate.
On the contrary, initial scientific evidence indicates that e-cigarettes appear to have a less harmful impact on the vocal cords than traditional smoking. A 2018 study suggested that e-cigarette use may not significantly affect voice quality.
When vape juice is heated it can potentially damage enamel and irritate soft tissue. As the ingredients tend to be thick and sticky, vapers may be at a higher risk of developing tooth decay and gum disease,” Dr Brown said. “Vape juice contains propylene glycol (PG) and vegetable glycerine (VG).
It's thought that nicotine is one of the main chemicals responsible for this delayed growth, however, other chemicals found in cigarettes may also contribute to stunted growth in heavy smokers and the children of smokers. Nicotine can also reduce or restrict growth by curbing a smoker's appetite.
Nicotine exposure during the teenage years can harm brain development, which continues until about age 25.
A 2024 study1 has confirmed that young people who vape perform worse in exercise tests. In fact, their exercise performance was on par with those who smoked! “They found it harder to breath, their muscles became more fatigued, and they were less fit overall.”
It also negatively affects the structure and function of the sperms in men. There is a risk that Vaping causes harm to fertility and during pregnancy.
Can vaping help with weight loss? Vapes containing nicotine may help prevent weight gain and lead to weight loss. However, vaping is not an effective long-term weight loss method and may have health risks. Nicotine may reduce appetite and food intake and increase metabolism.
Smoking-attributed nicotine is known to inhibit aromatase enzyme activity, which catalyzes the conversion of androgens into estrogens [10]. Consequently, nicotine reduces circulating estrogen levels and leads to early onset of menopause in women [11,12,13,14,15,16,17,18,19].
Lung function starts to improve 2 weeks to 3 months after quitting. From 1 to 12 months after quitting, symptoms such as coughing and breathing problems should improve as lung structures heal. If people wish to quit vaping, they can speak with a healthcare professional. Learn about 10 steps to quitting vaping.
Just like cigarettes, most vapes contain nicotine, and it may contribute to hair loss or thinning in these ways: Constricting blood vessels – Over time, nicotine intake can narrow blood vessels and reduce blood flow to the hair follicles. This means less oxygen and nutrients reach them, hindering healthy growth [8, 9].
Yes, your e-juice does contain calories, but the short answer is, it's not very many. One study cited by Colombia University quotes roughly 20 calories per a typical vape cartridge [4], meaning vape juice is unlikely to bring on any unwanted weight gain on its own.
Typically, manufacturers advise that 10 puffs on your vape are about the same as 10 puffs on your cigarette. They further speculate that 10 puffs are all you take on one cigarette. Of course, this varies based on how big your puffs are, how strong your vape device is, and how much nicotine you are using.
