coffee and caffeine effects on health

coffee and caffeine effects on health

Coffee or caffeine has numerous effects on the human body. The following article shows the physiological effects, effects depending on the phase of life or lifestyle, interactions with nutrients and drugs, and observed results in various diseases.

Physiological effects of the alkaloid caffeine

General health

As in most cases, whether coffee has a positive or negative effect on health depends on the dose. In excessively high doses, the alkaloid caffeine can lead to fear, restlessness, nervousness, irritability, or even insomnia. Scientific studies indicate a threshold of around 1.2 g per day.

In the long term, consuming 2-5 cups of coffee a day can positively affect mortality. This was slightly reduced in studies. The combination of caffeine and alcohol has a negative effect. Cardiovascular disorders, as well as psychological and neurological complications, are documented here.

Cardiovascular system

Caffeine speeds up the heart, metabolism, and breathing. Blood pressure and body temperature rise slightly. The blood vessels expand, and the blood flows to all organs increases.

Concentration, alertness, attention

Drinks containing caffeine have a stimulating effect, activate the central nervous system, and increase mental and physical performance.

sleep

The alkaloid is stimulating and has a short-term positive effect on the state of wakefulness and performance. However, contrary to some speculation, this does not compensate for a sleep deficit. Quite the opposite: in some people, caffeine consumption hurts sleep behavior after a specific time (usually 4 pm / 5 pm). It can lead to problems falling asleep. This is probably due to genetic variants of the so-called adenosine receptor. This explains caffeine's effect: It binds to the receptor, blocks it, and thus increases alertness and reduces tiredness.

Water and electrolyte balance

Caffeine has a diuretic effect (promotes urination). However, even at doses of up to 400 mg daily, this does not have a negative impact on the water and electrolyte balance over a more extended period of time.

Effects on different phases of life/lifestyle

pregnancy

The analysis shows that the metabolism of caffeine slows down during pregnancy. It is then broken down more slowly and excreted from the body. A maximum of 200 mg per day is therefore set for pregnant women. Studies have shown that up to 3 cups of coffee a day does not affect birth weight, the number of premature births, or stunted growth cases. So far, there is insufficient evidence to confirm or refute the influence on birth weight and other endpoints related to pregnancy.

Sports

Caffeine increases lipolysis, which means that free fatty acids can be used, and a glycogen-saving effect occurs. Consumption of 3-9 mg per kg of body weight between 30 and 90 minutes before physical activity has been shown to increase athletic endurance and performance

what is the new definition of health?

The World Health Organization (WHO) has redefined health as a state of complete physical, mental and social well-being and not merely the absenteeism of disease or infirmity. This definition was adopted in 1948 and has been widely accepted by the global health community. The new definition of health reflects the growing understanding that health is not just about the absence of disease, but also about the attendance of positive factors that contribute to well-being. These factors include social and economic factors, as well as individual factors such as mental health and physical activity. The new definition of health has important implications for public health policy. It suggests that the focus of public health should be on promoting positive health, not just preventing disease. This means investing in factors that contribute to well-being, such as education, housing, and employment. The new definition of health is also important for individuals. It suggests that we should thin...
