Is the time you drink coffee affecting your sleep?

I can’t get over those people who drink a cup of coffee just before bed as a night-cap. And then they tell you that they sleep like a baby!

Well, not all of us mere mortals can get away with this habit unscathed.

Caffeine has a half-life of 4 to 6 hours. Meaning that if you drink a cup of coffee later in the day, say at 5pm, then by 9 or 10pm there is still a whopping ½ of the caffeine still circulating around your system, keeping you revved up and stimulated.

Not only will coffee reduce your total sleep time, it can also can reduce the amount of deep, restorative sleep that you enjoy.

So next time you reach for that cup of coffee, keep your eye on the clock and think of caffeine’s half-life. The best time to drink coffee is early in the day, ideally before midday, so your body can do its job and clear most of it out of your system in readiness for a great night’s sleep!
