Caffeine’s Short‑Term Effects
-
Alertness & Cognitive Performance: A 200 mg dose (roughly one cup of brewed coffee) can improve reaction time by up to 12 % (2026 JAMA study).
-
Metabolic Boost: Increases resting metabolic rate by 3–4 %, aiding short‑term weight management.
-
Side Effects: Restlessness, insomnia, and increased heart rate—particularly when consumed later in the day.
Nicotine’s Long‑Term Effects
-
Cardiovascular Disease: Chronic nicotine exposure raises blood pressure and arterial stiffness, increasing heart disease risk by 30 % (2026 American Heart Association report).
-
Cancer Risk: Smoking remains the leading cause of lung cancer; vaping’s long‑term carcinogenic profile is still under investigation.
-
Addiction: Nicotine’s half‑life (~2 hrs) and rapid brain uptake make it highly addictive, with withdrawal symptoms such as irritability and anxiety.
Combined Effects
-
Synergistic Stress Response: Simultaneous caffeine and nicotine intake can amplify cortisol secretion, leading to heightened stress over time.
-
Sleep Disruption: Both substances delay sleep onset; combined use can reduce total sleep time by 30 minutes per night (2026 Sleep Medicine Review).
📌 Important Takeaways:
-
Caffeine boosts alertness but can impair sleep if consumed after 2 pm.
-
Nicotine’s health risks are primarily long‑term and cumulative.
-
Mixing caffeine and nicotine may intensify cardiovascular strain.
