The effects of evening coffee on your body

Coffee is a widely consumed beverage that provides the energy and alertness that many people need when they wake up in the morning. However, drinking coffee in the evening may have some negative effects on the body. This article will explore the effects of evening coffee drinking on aspects such as sleep, digestive system, and cardiovascular health.

1. Decreased sleep quality

Coffee contains a substance called caffeine, which is a stimulant neurotransmitter. When we consume too much caffeine, it blocks adenosine receptors and inhibits adenosine from entering the brain. This causes us to feel more awake and alert.

However, consuming too much caffeine in the evening may disrupt our normal sleep cycle. Studies have shown that consuming more than 150 mg of caffeine (equivalent to a cup of medium-strength black coffee) about 6 hours before is enough to significantly reduce the amount of deep sleep. This means that drinking coffee in the evening may lead to poor sleep quality and difficulty falling asleep or staying asleep.

2. Digestive problems

Caffeine also has some effects on the digestive system. It can stimulate gastric acid secretion and increase the amount of gastric acid produced. This can cause problems such as heartburn, stomach pain, and indigestion.

In addition, coffee has a mild diuretic effect, which may increase urinary frequency and bladder pressure. If you drink coffee in the evening and need to get up frequently to urinate, this will interfere with our normal rest and recovery process.

3. Cardiovascular health risks

High caffeine intake may have negative effects on cardiovascular health. Studies have shown a link between excessive caffeine intake and cardiovascular problems such as high blood pressure, heart rhythm disorders and coronary heart disease.

Especially when too much caffeine is consumed in the evening, it may increase heart rate and blood pressure in the hours before bedtime due to its stimulant effects. This is particularly important for those who already have cardiovascular disease or high blood pressure.

in conclusion

Drinking coffee in the evening may have a series of negative effects on the body, including decreased sleep quality, digestive problems, and increased cardiovascular health risks. Therefore, we should try to avoid consuming too much caffeine in the evening.

If you really need to stay awake and alert at night, consider choosing low-caffeine or decaffeinated alternatives to coffee. It’s also a good idea to stop consuming caffeinated beverages at least 6 hours before bedtime.

In summary, understanding and controlling your evening coffee intake is key to maintaining good sleep, digestive system, and cardiovascular health.
