The cost of Starbucks (DW#709)
Isn’t it amazing how much a cup of coffee can cost these days in a fancy coffee shop?
Well, it turns out that shot of expresso is costing you more than money.
Caffeine does not actually give us energy. What it does do is mask our fatigue. It basically deactivates that part of the brain which tells you that you are tired. What this means is that you are not "getting" new energy from caffeine. You are simply ‘borrowing energy’ from your future self.
Plus caffeine stays in your body for a long time. It has a "half-life’ of 5 to 6 hours which means that if you have 100 mg of caffeine at 4:00 pm, around half of that caffeine is still bouncing around in your brain at 10pm. Half the caffeine is STILL with you even 6 hours later. No wonder you cannot sleep.
Now many people firmly swear that caffeine does not impact them and that they can sleep like babies even after several cups. Are you one of those? If so, great. If not, consider a caffeine curfew.
Stop drinking coffee (or if you are very sensitive, even tea) by early afternoon. Noon, 1 or 2pm. Experiment with what is ideal for you.
