Caffeine and sleep?
 
Does anyone have any suggestions as to how many hours before bedtime that a person should not have any more caffeinated beverages in order to sleep well? Sometimes I sleep well if I have caffeine late in the day, and other times I don't sleep well if I've had no caffeine, so I'm not sure what to think. Do you think that it is over-rated that too much caffeine late in the day interferes with sleep? Afterall, the British have tea late in the day, and it doesn't seem to affect them adversely. Thanks in advance for any information on this subject.

Hi.
Caffeine stays in our body for almost ten hours after last drinking it! So the earlier one has coffee or any other caffeine containing beverage, the better the chances of sound sleep. So you should try and have your last cup before 5 pm

The half life of caffeine (when it's benefit peaks) is 4 hours. So caffeine from a coke at noon will peak at 4 and be gone at 8.

Your body may like caffeine in the short term, particularly if you are low on sleep and need to remain energetic. Caffeine blocks adenosine reception so you experience alert. It injects adrenaline into the structure to give you boost up. And it manipulates dopamine assembly to make you feel good.

I drink a lot of tea so find if I have my last cup at about 6pm I can go to sleep about 11pm.

Hope this helps

Well to a lot of extent, it depends on the type of coffee/coffee beans you have. Different coffee have different caffeine content. To be on the safe side, never have coffee 5 hours before you sleep.

There is a difference between tea and coffee. Tea is more of a refreshment whereas coffee is a stimulant. You can have tea right before sleeping and you'll be able to have a perfectly normal sleep. Whereas coffee stimulates your brain activity and keep you awake.

Coffee intake during the day boosts our mind and alertness but at night reduces the sleep time and will not get deep sleep.
