Unlike caffeine, which has a longer half-life and can lead to prolonged adrenal stress and jitteriness, nicotine’s shorter duration of action may cause less strain on the body, reducing prolonged stimulation of the adrenal glands. This makes it an appealing choice for people looking to avoid the sometimes over-stimulating effects of caffeine, offering a shorter, potentially smoother burst of focus.
Nicotine’s stimulation of the sympathetic nervous system, often called the “fight or flight” response, is key to its energizing properties. When nicotine is absorbed, it prompts the release of key neurotransmitters like dopamine, epinephrine, and norepinephrine. These chemicals play a role in improving mood, focus, and alertness, contributing to a sensation of heightened energy and mental sharpness.
This release of neurotransmitters can create a feeling of readiness and alertness, which may be why some individuals experience enhanced productivity. However, regular stimulation of the sympathetic nervous system can strain the body over time, so any benefit must be weighed against the potential for stress on the body if used habitually.
