How long do the effects of coffee last? How many hours can a child drink it before it wears off?

Effects of coffee and how long it lasts

Coffee is a common beverage that contains caffeine and other ingredients that can provide a boost of alertness, increased alertness, and improved concentration. However, children have different physical and physiological characteristics from adults, so their reactions to coffee may also be different.

1. Effects of coffee on children

Children may experience similar effects to adults after consuming moderate amounts of coffee. Because children's brains are not fully developed, they may be more susceptible to side effects such as excitement, anxiety, or insomnia caused by caffeine. In addition, excessive caffeine intake in some cases may also cause increased heart rate, blood pressure, and digestive problems.

2. Common Dosages and Duration

According to the US Food and Drug Administration (FDA), children under the age of 6 should avoid using products containing large amounts or high concentrations of caffeine. For children aged 7 to 12, it is relatively safe to consume no more than 85 mg of caffeine per day. For adolescents aged 13 and above, a more reasonable limit is no more than 100 mg of caffeine per day.

An 8-ounce cup of regular coffee contains about 95 mg of caffeine. So, based on the above recommendations, children between the ages of 7 and 12 can drink a regular-sized (8-ounce) cup of coffee without significant side effects.

Regarding the duration, individual differences are large. Generally speaking, adults can feel the refreshing effect for about 4-6 hours after consuming a moderate amount of coffee. However, children may feel the effect for a longer time at the same dose due to differences in body metabolism and physiological characteristics from adults.

3. Child expiration time

Children are more sensitive to caffeine and metabolize it more slowly, so even after drinking a regular sized (8 oz) cup of coffee in moderation, they may feel the effects of caffeine for longer. Generally, the effects of caffeine in children may last 6-8 hours, or even longer.

However, each child reacts differently to caffeine. Some children may be more sensitive to caffeine, and they will soon experience side effects such as excitement and anxiety after consuming a moderate amount of caffeine, and these side effects will also last for a relatively long time. Other children may not be very sensitive to caffeine, and the effects and duration of the same dose are relatively shorter.

4. How long does it take for the drug to become ineffective after a child drinks it?

When a child drinks a regular-sized (8 ounce) cup of coffee, the caffeine in their body begins to be absorbed into the bloodstream. Over time, the liver metabolizes most of the caffeine in the body and converts it into harmless substances that are excreted from the body.

Based on the above discussion, after drinking a regular-sized (8-ounce) cup of coffee in moderation, a child may feel the effects of caffeine for 6-8 hours, or even longer. However, this is only a rough estimate, and the specific situation needs to take into account individual differences and other factors.

in conclusion

In short, before giving coffee to children, their age, physical condition and personal characteristics should be carefully considered. According to relevant recommendations, consuming a small amount of caffeine within a moderate range is relatively safe and reasonable for children over 7 years old. However, each child reacts differently to caffeine, and its duration of action will also vary.

To ensure your child can enjoy the effects of coffee safely and healthily, please talk to your doctor before giving them any caffeinated beverages and follow relevant professional advice.
