To caffeinate or de-caffeinate, that is the question…

Have you ever wondered how your caffeine intake affects your sleep? With the UK coffee week fast approaching we decided to do some investigating on the subject and share our findings with you...
It’s a well known fact that a good cup of coffee can help you shift the early morning, afternoon or evening tiredness, however, what’s not as well known is how long the affects of coffee remain within the body. Studies have shown that a few cups of coffee over the course of a morning can help people work more efficiently, but if you continue this in to the afternoon and evening you could be seriously hindering your nights rest.
Here are some facts about coffee and caffeine:
- Around £850 million pounds a year is spent on coffee within the UK
- Coffee accounts for 54% of caffeine consumption in the world, Tea accounts for around 43%
- Coffee reaches its peak level within your blood within 30-60 minutes
- The affects of caffeine can remain in the body for 8-14 hours
The reason coffee can make you feel more alert and keep tiredness at bay is because it blocks a chemical called melatonin; which helps your body know it’s time to rest, from entering the brain. Melatonin is most prominent around 2 hours before your usual bedtime, and then peaks again between 2am and 4am. The higher your Melatonin levels the better night’s sleep you should theoretically have. It has been found that people who drink caffeinated coffee could have half the level of Melatonin than those who drink decaffeinated.
This isn’t all bad news for those who love a cup of coffee throughout the day; the best thing to do is simply switch to decaffeinated coffee products from lunch time onwards. Also, remain within the advised caffeine limits, which is around 3 cups per day. This should help you get to sleep easier and remain asleep for longer, as Melatonin levels should have regenerated allowing your brain to tell your body it’s time to sleep.
