Caffeine
Caffeine can be a great way to improve mental alertness and reduce fatigue, but caution should be used to avoid any negative side effects…
Caffeine is naturally produced by a variety of different plants and acts as a pesticide to protect the plant or seeds against insects. It is a compound known as a xanthine alkaloid (methylxanthine) that acts as a stimulant drug in the human body. The most commonly consumed sources of caffeine are Coffee, Tea (Top Ten Teas), and Cocoa (Cacao) although other sources like Yerba Mate, Kola Nut, and Guarana are also gaining popularity and becoming mainstream. Caffeine is also commonly added to carbonated drinks, Energy Drinks and some medications for cold and headache relief.
Stimulant
Caffeine acts as a central nervous system stimulant in the human body, allowing it to help reduce fatigue and improve mental alertness. In fact, caffeine is the most commonly used psychoactive substance worldwide. It is estimated that 90% of adults in North America consume caffeine daily. The stimulant effects of caffeine also result in an increased heart rate, a relaxation of smooth muscle, and increased stomach acid secretion.
Diuretic
When not used on a daily basis, caffeine has a diuretic effect, which means that it increases the shedding of water from the kidneys and thus increases urination. It also reduces the water content of the body, which can lead to dehydration. The flushing caused by this diuretic effect can cause a reduction in calcium and other important electrolytes in the body. This is why caffeine consumption can increase the risk of Osteoporosis. For more information, please see our Electrolytes article. Those who use caffeine on a regular basis and develop tolerance generally no longer get this diuretic effect.
Asthma
Traditionally, a cup of coffee was used to help treat mild Asthma attacks in children. Due to its ability to relax smooth muscle, caffeine can act as a bronchodilator in people with asthma. Caffeine is very similar in structure to theophylline, another methylxanthine commonly used to treat asthma. Recent research has found that caffeine can be used in place of theophylline when necessary for bronchodilation in asthmatics.
Energy Metabolism
Professional athletes will often use small to moderate doses of caffeine to help improve their athletic performance. It helps to mobilize fat from the muscle and increase blood epinephrine levels. These effects allow the muscles to mobilize and use fat for energy, which spares muscle glycogen. This allows for better results with endurance exercise, by giving longer acting energy. The dosing for this effect is very specific, as excess can quickly become detrimental for athletic performance, by throwing off co-ordination and balance. The metabolic effects of caffeine may also allow it to help prevent the development of Type II Diabetes. Unfortunately, once diabetes is already present, caffeine’s effects are actually detrimental and can worsen blood sugar control.
Caffeine and Constipation
Because of its diuretic effects, caffeine can cause dehydration, a condition that can greatly worsen constipation over time. This seems counter-intuitive to the many people who drink coffee to promote a bowel movement in the morning. This direct effect is likely due to the relaxation of smooth muscle caused by caffeine. In general, it is a good idea to find other ways to promote bowel movements, rather than relying on a stimulant like caffeine.
Toxicity
The side effects of caffeine exposure depend on the dose. At typical doses, it can cause: insomnia, nervousness, restlessness, gastritis, nausea, increased heart rate, high blood pressure, and increased urination. Often people will complain of muscle tremors known as the “caffeine jitters” after ingesting excess caffeine. Larger doses can cause: headache, anxiety, agitation, ringing in the ears, stomach cramps, sensory disturbances, vomiting, rapid breathing, tremors, delirium, irregular heartbeat, and even convulsions. Fatal overdoses by ingestion are rare because the irritation of the gastric lining caused by caffeine generally results in vomiting of excess amounts. This irritation is also why caffeine intake is associated with an increased risk of developing Ulcers. Prolonged use of caffeine has also been shown to be associated with increased risk of developing several health conditions such as High Blood Pressure, and Cardiovascular disease.
