After drinking coffee at 7 o'clock, what time can I fall asleep?

Effects of caffeine on sleep

Coffee is a common drink that contains a certain amount of caffeine. Caffeine is a stimulant that can refresh the mind and increase alertness. However, excessive caffeine intake may have an adverse effect on sleep.

After drinking coffee at 7 o'clock

Suppose a person drinks a cup of coffee with a moderate amount of caffeine at 7 pm. According to research, it takes about 6 hours for the human body to absorb and metabolize caffeine. This means that after drinking this cup of coffee, most of the caffeine in the body will not be excreted until about 1 am.

The time it takes to fall asleep is affected by many factors

However, not everyone is affected to the same degree. Individual differences, physical condition, age and other factors may cause each person to react differently to the same dose of a stimulant.

It is recommended to avoid excessive intake of stimulants at night

In order to ensure good sleep quality, it is recommended to avoid excessive intake of stimulants at night. Especially for those who are easily stimulated by caffeine, they should try to avoid drinking coffee or other caffeinated drinks at night.
