Even if you're not one of those people who turns to science to improve their lives, this is something worth reading.
Reaching for a cup of coffee the first thing in the morning might not be the most effective move.
Caffeine, as we all know, helps us feel alert and awake because it increases the level of cortisol in our bodies so it's powers are less effective when cortisol is already at its peak.
Cortisol peaks and falls when we wake up, around lunchtime and also late afternoon. The best time to drink coffee is after your cortisol level drops between 9.30am-11.30am and 1.30pm-5.30pm. So if you're already stuck in the habit of drinking your coffee in the first one to two hours of being awake, or any time when your body's cortisol levels are peaking, here's the bad news: your body may actually be becoming increasingly immune to caffeine.[Vogue]
