The Fountain of Youth in Your Coffee Cup: How Caffeine Fights Aging
Caffeine is a naturally occurring stimulant found in many foods and beverages, including coffee, tea, chocolate, and energy drinks. It is the most widely consumed psychoactive drug in the world, between 30- 90% of adults consuming it regularly, depending on location.1 While caffeine is often associated with increased energy and alertness, it has also been found to play a role in anti-aging.
Caffeine works by blocking the action of adenosine, an inhibitory neurotransmitter in the brain.2 Adenosine builds up in the brain throughout the day, leading to feelings of drowsiness and a decrease in cognitive function. By blocking adenosine, caffeine can increase the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine.3,4 This can improve various aspects of brain function, including mood, vigilance, reaction time, and memory.
In addition to its effects on brain function, caffeine has also been found to have anti-aging properties. One of the key mechanisms by which caffeine may promote anti-aging is through its ability to act as an antioxidant.5,6 Antioxidants are substances that neutralize free radicals, unstable molecules that can damage cells and contribute to the aging process.
In addition to its antioxidant properties, caffeine has been found to have anti-inflammatory effects.7-9 Inflammation is a natural process in the body that helps to fight off infections and heal injuries, but chronic inflammation can contribute to a wide range of health problems, including heart disease, cancer, and Alzheimer's disease. By reducing inflammation in the body, caffeine may help to slow the aging process and reduce the risk of age-related diseases.
Caffeine has also been found to have neuroprotective properties. Research suggests that caffeine may help to protect against age-related cognitive decline and reduce the risk of neurodegenerative diseases like Alzheimer's and Parkinson's disease. 10-12
In addition to its effects on the brain, caffeine may also promote anti-aging by improving physical performance. For example, a review aimed to evaluate the effectiveness of a moderate dose of caffeine on soccer physical performance. The researchers conducted a structured search following specific guidelines to identify studies that compared caffeine intake with an identical placebo situation. The review included 17 articles that investigated the effects of caffeine on soccer-specific abilities and muscle damage. The results of the review showed that a moderate dose of caffeine, ingested 5-60 minutes before a soccer practice, can produce valuable improvements in certain abilities related to enhanced soccer physical performance. Specifically, five investigations found that caffeine had ergogenic effects (enhancement of physical performance or work output) on jump performance, four investigations found the same effect on repeated sprint ability, and two investigations found the same effect on running distance during a simulated soccer game.13
Caffeine has been found to increase the mobilization of fatty acids from fat tissue, making them available for use as energy by the body's cells.14 This can improve physical performance and help to prevent muscle fatigue during exercise. Studies have also suggested that caffeine may increase metabolic rate, leading to increased calorie burning and weight loss.15-17
In conclusion, caffeine is a potent antioxidant with anti-inflammatory and neuroprotective properties that may play a role in anti-aging.
