This is what caffeine does to your sleep

Postdate: 05 February 2018

Drinking two cups of black coffee per day is part of a healthy lifestyle. Timing is important in this. Drinking coffee before bedtime can actually affect your brain. Read more about how below.

Need energy? Have a mug of coffee
A cup of coffee before bedtime? Might not be such a good idea. Caffeine can make it harder to fall asleep. Not only coffee contains caffeine. It is also in cocoa, energy drinks, green tea and cola at certain levels. Caffeine in tea is known as theine. Not everyone notices the effects of these foods because their caffeine content varies per product. There are also differences in how quickly caffeine leaves your body again. Most people notice that they are temporarily more alert, concentrate better and have more energy after a cup of coffee. This is why coffee is so popular early in the morning.

Coffee versus sleeping badly
In avid coffee drinkers, habituation may occur over time. They will notice the bad effects of coffee as soon as they stop drinking it. You can still lie awake long after you have been drinking a cup of coffee. This is because caffeine works as a stimulant: your blood pressure goes up; your breathing rate increases temporarily and adrenaline is released. If you are sensitive to caffeine, you can have even more trouble from this during your sleep, such as waking up more frequently. Too much caffeine can cause restlessness, headaches, heart palpitations and irritability. An average adult without mental or physical complaints can tolerate about four cups of coffee a day without experiencing these annoying effects.

Not everyone is equally sensitive to the effects of caffeine. This depends on things such as age, gender and the extent to which you are used to caffeine. Also, remember that there are more 'disturbing factors’ for a good night's sleep, such as sugar and nicotine.
