One of the most common recommendations for appropriate sleep hygiene practices is to avoid caffeine close to bedtime.We report that, for healthy adults, caffeine consumption is relatively safe, but that for some vulnerable populations, caffeine consumption could be harmful, including impairments in cardiovascular function, sleep, and substance use.

Caffeine promotes gastric acid secretion and increases gastrointestinal motility. It is often combined in products with analgesics and ergot alkaloids, relieving the symptoms of migraine and other types of headaches. Finally, caffeine acts as a mild diuretic. While caffeine can help reduce pain in the short term, it can also have negative effects, especially when consumed in large quantities: Increased Sensitivity: Over time, regular caffeine consumption can lead to increased sensitivity to pain, particularly if you experience withdrawal symptoms.Moderate caffeine consumption (≤400 mg/day) is considered safe in healthy adults and may offer potential benefits for mental health, while excessive intake is associated with adverse effects and can aggravate symptoms of anxiety and depression.Caffeine’s actions on adenosine receptors may help people feel less discomfort [14-18]. It directly affects pain signaling by inhibiting brain adenosine receptors and peripheral adenosine receptors on sensory afferents.While caffeine pills are safe when used in moderation, excessive use can lead to negative side effects such as jitteriness, increased heart rate, anxiety, and sleep disturbances. Overconsumption can also cause caffeine dependence, leading to withdrawal symptoms when intake is reduced.
Why is coffee called a drug?
Caffeine is a psychoactive (mind-altering) drug that affects how we think and feel. It is a stimulant that speeds up our breathing, heart rate, thoughts and actions. Caffeine is found in the seeds, leaves and fruit of certain shrubs, including coffee and tea plants. According to the FDA, the half-life of caffeine — the time it takes for the starting amount of the substance to reduce by half — is between four and six hours. This means that up to six hours after drinking a caffeinated beverage, half of the caffeine you consumed is still present in your body — keeping you alert.Caffeine administration affects the functioning of the cardiovascular, respiratory, renal, and nervous systems.Caffeine has very high bioavailability, which means that nearly all of the caffeine consumed is taken up by the body. Within an hour after consumption, the liver and kidneys begin to process and eliminate caffeine through the urine.If you take the same caffeine dose in tablet form, the peak caffeine level will be the same but it takes longer – between 60 and 75 minutes – to reach that peak. For most people, the caffeine level in your body halves roughly every six hours.

Headaches result from constricting blood vessels in the brain.
Is caffeine the most abused drug?
Caffeine is the most widely used drug in the world. In the United States, more than 90% of adults use it regularly, and, among them, average consumption is more than 200 mg of caffeine per day2—more caffeine than is contained in two 6-ounce cups of coffee or five 12-ounce cans of soft drinks. Some people can manage up to 400 mg of caffeine per day. But experts agree that 600 mg (four to seven cups of coffee) is probably too much. Bear in mind that five ounces of coffee is less than the large cup you pick up at your local coffee shop and your favorite coffee mug may be more than five ounces.Up to 400 milligrams (mg) of caffeine a day seems safe for most adults. That’s about the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two energy shot drinks. Keep in mind that the caffeine content in drinks varies widely.Extremely high daily intakes of 1,000 mg or more per day have been reported to cause nervousness, jitteriness and similar symptoms in most people, whereas even a moderate intake may lead to similar effects in caffeine-sensitive individuals.
