New research shows that you can increase your charisma and ability to inspire people by being more mindful about the time of day in which you seek to do so. It turns out that our natural circadian rhythms play a big role in how charismatic we are. That’s because the circadian process is a powerful driver of cognitive function, moods, and behaviors. We communicate more clearly and demonstrate more positive emotions when we are at peak levels of alertness during typical periods of wakefulness and are less effective in these activities during typical periods of sleep, even if we are awake at those times. This article discusses how you can leverage your natural rhythms to help improve your charisma and, ultimately, how effective you are at inspiring others.
