Coffee is one of the most popular drinks in the world because it makes people feel good. The feeling it arouses in people is due to the effects it has on the body.
Early Effects. One of the first things we do in the mornings when we wake up is go straight to our coffee machine and get our brew going. Once you pour yourself a cup of coffee, it does not take long for the effects of the drink to be felt on the body.
Scientific studies show that caffeine, which is found in coffee, starts affecting the body 10 minutes after its ingestion. It creates different pathological effects when it gets into the bloodstream, including increased heart rate and blood pressure.
As coffee continues to take effect from 10 minutes to one and a half hours after drinking, it counteracts the effects of small alcohol quantities taken. It makes the drinkers more alert and improves their performance although they will still feel dizzy.
Increased Concentration and Alertness. The full effects of coffee start appearing after 20 minutes, when people start getting more alert. They will also be able to concentrate better. According to a U.S. researcher, this state can go on up to 10 hours later. During this period, people are less likely to have cognitive failures like forgetting where they place items or making wrong choices.
Enhanced Athletic Performance. In addition to improving brain function, coffee can enhance athletic performance after 30 minutes of drinking a cup. It helps the body make better use of energy by affecting the spinal motor neurons when the level of serotonin in the brain increases. In addition, caffeine releases adrenaline, which the body uses for energy instead of glycogen, allowing people to exert themselves longer before feeling tired.
More Energy Expenditure. Coffee helps in burning body fat between 30 minutes and four hours after drinking it. A large study involving men of normal weight who did not exercise showed that only 50 mg of coffee increased energy expenditure notably. Coffee helps the body burn fat even when people are physically inactive. It also helps the body metabolize food faster, which is good for weight loss.
Improved Mood. Between 30 minutes and six hours after drinking coffee, people tend to be in better moods as their anxiety decreases. Studies show that consuming at least 100 mg of coffee improves feelings of contentment and inertia within this period.
Varying Effects. Coffee tends to have different effects between two and 12 hours after drinking it. Different people react differently, and even the same individuals may have different effects on different days. Although the effects of coffee typically start wearing off after two to three hours, the effects may last up to 12 hours in some people. Several factors influence the times coffee takes to wear off, including sensitivity to caffeine and age.
Withdrawal Symptoms. For some people, the effects of coffee may last up to 24 hours. However, regular coffee drinkers usually experience withdrawal symptoms after 18 hours, which may include fatigue and headache. While some people do not experience the withdrawal symptoms, those who do may experience the effects for between two and nine days.
Effects of Regular Consumption of Coffee. Many people drink at least a cup of coffee almost every day. In such a situation, the body builds some tolerance to coffee, and its effects will be relatively minimal. Different people have different tolerance levels.
These effects play a significant role in placing coffee as the second most popular drink in the world after water.
