As part of Science Week 2020, neuroscientist Ian Robertson is sharing top tips to help us apply science to our day to day lives.
Take, for example, your daily cup(s) of coffee. According to Robertson, caffeine is a stimulant and actually boosts brain function. It causes an uptake in the dopamine transmitter and this plays a big role in putting you in good mood.
But, of course, there is a catch.
If you're feeling edgy, the extra adrenaline hormone that coffee produces can trigger the amygdala part of the brain, making you feel even more anxious. That's when that nervous, jittery feeling kicks in.
So, what is a coffee drinker to do?
Robertson suggests limiting yourself to a maximum of three cups a day. He also suggests making them earlier in the day so that they can help you wake up and stay alert, but wash through your body by nightfall when your brain needs a rest.
