Making an important decision?
Sleep on it!
When you’re at the end of your day and find yourself finally getting around to thinking about that decision you’ve been putting off, the advice of ‘sleep on it’ is not just an old wives’ tale. Scientific research confirms that a person should not make an important decision at the end of the day, but instead wait until morning, following a good night’s sleep.
Two reasons this is good advice:
Firstly, at the end of the day we experience “decision fatigue.” According to the American Medical Association, this is a state of mental overload that can impede a person’s ability to continue making decisions. The average person makes over 35,000 decisions by the end of a day, says Dr. MacLean, a psychiatrist, which takes energy and can result in brain fog. In addition, the wear and tear on our brains leads us to make more reckless decisions, such as impulse eating and shopping.
Secondly, the most accurate decisions are made early in the day, according to a study published in the journal, Cognition. Not only is this because decision fatigue has not yet occurred, but can also be attributed to adequate sleep, which is linked to better productivity, concentration, and cognition – the mental ability to acquire and perceive knowledge or concepts.
So, the next time you find yourself at the end of the day with your head spinning and you asking yourself, “What do I do?” The answer is to get a good night’s sleep, knowing your decision-making ability will be improved in the morning and your decision more accurate.
