Effects of caffeine: invigorating state or negative health effects?
Coffee is a very controversial drink, which has both supporters and opponents. Some argue that its effects on the body as a whole are not negative, while others warn of potentially negative health effects. Where is the real essence of this issue? Is it possible to consume this invigorating drink daily, or are there any restrictions?
How does coffee affect the human body?
The effect of caffeine on the body is closely related to its effect on the central nervous system. When caffeine reaches the brain, it activates receptors, stimulating the mind, promoting wakefulness and increasing both mental and physical performance. This drink also helps increase levels of the hormone dopamine, which is responsible for feelings of joy and the desire to achieve goals, which has a positive effect on mood.
The caffeine contained in coffee exhibits excellent anti-cancer properties due to the presence of antioxidants and anti-inflammatory components in the drink. Its ability to stimulate brain activity is an integral factor, improving the functioning of the central nervous system and giving a feeling of alertness and increased concentration at work.
Regular coffee consumption reduces the risk of developing liver cancer and also prevents senile dementia, Alzheimer’s disease and Parkinson’s disease. Coffee contains chlorogenic acid, which has antiviral, antibacterial and anti-inflammatory properties, and can also neutralize free radicals, slowing down the aging process of cells.
This drink is also known for its diuretic properties, helping to cleanse the body of toxins daily. In addition, the caffeine in coffee helps increase endurance during physical activity and promotes weight loss.
Negative effects of caffeine
Caffeine harms the human body through several aspects. This substance is addictive, requiring an increase in dose over time. Large amounts of caffeine can lead to loss of calcium and magnesium and also have negative effects on the nervous system. It is contraindicated for people with decompensated diseases of the cardiovascular system. Excessive caffeine consumption stimulates diuresis, causing intense kidney function and bladder irritation.
Caffeine addiction can lead to negative effects when stopped abruptly, including depression, headaches, and weakness. Large doses of caffeine can cause tremors, increased anxiety and panic attacks. In individuals with cardiovascular disease, high doses of caffeine can lead to serious problems such as tachycardia, increased blood pressure and arrhythmias. It is also worth noting the diuretic effect, which can cause dehydration and diarrhea. Despite the temporary feeling of wakefulness, caffeine does not provide energy and should be limited to maintain safe doses.
Who should avoid the invigorating drink?
Drinking coffee in excess, more than three cups a day leads to negative consequences for the nervous system and the leaching of important microelements such as calcium and magnesium. This can affect the quality of sleep, make it difficult to fall asleep and even cause insomnia. It is recommended that people with osteoporosis, menopause, heart disease, high blood pressure or kidney problems limit their coffee drinking.
As an alternative, you can use other drinks that contain doses of caffeine, but in smaller quantities and more gently stimulating the nervous system. Coffee alternatives include black and green tea, cocoa, chicory, matcha and kombucha. Not only are they caffeine-free, but they are also enriched with antioxidants, vitamins, and beneficial chemicals to help improve overall health. Switching to these drinks can bring the joy of a variety of flavors while supporting your body.
