We told you about it a few months ago:pressing the "snooze" button on the alarm clock to delay it by 5, 10 or 15 minutes (it's tempting some mornings, we're not going to lie to each other!) is bad for us because “earned” sleep is of poor quality. Now a neuroscientist goes further and says it's downright bad for your health. The reason ? According to Professor Matthew Walker (who teaches at the Scientific Center for Human Sleep at the University of California), pressing the said button inflicts "cardiovascular assaults" on the body and abuses our nervous system:the sound of the alarm clock causes an increase in heart rate and a spike in blood pressure. When we delay waking up, it happens several times in a short period of time. In the long term, if we do this every day, it can have an impact on the nervous system and the heart.
We know it:coffee can prevent us from sleeping because caffeine acts on adenosine, a chemical component whose concentration increases throughout the day to indicate to the brain that it is time to go to sleep. By placing itself on the adenosine receptors, caffeine deactivates them and we do not feel the urge to sleep. What is less known is that decaffeinated coffee is not completely caffeine-free:a cup contains about a third of the amount of caffeine of a classic coffee. So that means that if you drink three decaf… well, it's like drinking a real coffee!
Getting up as soon as you hear the alarm clock and having a light hand on the decaf, here are two good resolutions that we will put in place!
