5 reasons why you should sleep on it when making important decisions
By Jason Wooden, PhD | June 25, 2022
When you’re tired and stressed, your mind doesn’t work as well as it should which can lead to impaired judgement and poorer decision making. What “sleeping on it” is really about is better outcomes because you’re making decisions under better circumstances. After a night of restful sleep, it’ll be easier to think things through and you’ll approach your decision with an improved mood.
The thing about decisions and “sleeping on it”
To decide or not to decide, now that is the question
The average adult makes thousands of decisions every day ranging from the trivial to the more serious.
What this article is really focused on is the downsides of making important decisions when you’re over-tired and why it’s sometimes better to “sleep on it”.
Not the small stuff but the big stuff that can affect your life in important ways.
Major decisions can be stressful and sometimes overwhelming especially if your mind is racing with the possibilities.
Whether it’s accepting a new job, figuring out a relationship, dealing with a family issues, or struggling on what to do about something health related, making decisions when you’re strung out or fatigued can be even more challenging.
It can also lead to outcomes you don’t want.
The hope is that after a night of solid rest it will be easier to make sense of things with a refreshed and clearer mind.
Does sleeping on it really work?
Like many things in life, it all depends on your situation.
And yes, sometimes it’s better to come to a decision sooner rather than later.
However, let’s assume you can wait till the next day.
We’re going to look at what happens when you make decisions in the fog of fatigue and why it’s sometimes better to sleep on it.
The 5 reasons why you SHOULD sleep on it
When people say you should sleep on it, it’s not about magical hocus pocus that happens while you’re asleep.
It’s really about better outcomes because you’re making decisions under better circumstances.
We’ve all experienced at one time or another how different things in life looks after a night of rest.
And we’ve also seen how much easier it is to think too.
Unfortunately, we’re in the midst of a silent public health epidemic. Every night one in three adults struggle with insomnia and wake up sleep-deprived.
That’s a ton of people living their waking hours overtired and extra stressed. It’s likely more than a few of them are making important decisions when they’re not at their best.
Whether you’re physically, mentally, or emotionally drained, a night of restful sleep can make a BIG difference:
1) Your brain will work better
Let’s be honest.
When you’re behind the eight ball on sleep, your mind isn’t working as well as it should. It’s harder to focus and think clearly.
There’s growing research showing how sleep deprivation affects human cognitive functions such as working memory, learning, attention, AND decision-making.
Overall, what they’re confirming is that insufficient sleep can lead to impaired judgment and poorer decision making.
(One study found that sleep-deprived gamblers were more likely to expect gains and make light of losses.)
And would you believe studies have found that when you’re sleep-deprived what it does to your brain is the same as being drunk?
After sleeping on it, you’ll be able to focus and make your decision with a clearer mind.
2) Your outlook will be better
It’s obvious to most people that your outlook isn’t the same when you’re tired and stressed. Sleep-deprived people are moodier, more irritable, have a harder time coping, and our more like to feel down.
It’s also pretty obvious how a negative outlook can affect how you think about an issue and the possible outcomes.
Studies show people who sleep poorly have more negative moods (anger, frustration, irritability, sadness) and fewer positive moods.
After sleeping on it, you can at least make your decision with a less negative and hopefully more even outlook.
3) You won’t feel as stressed
When you’re over-tired, you’re also likely to be more stressed. In fact, there’s a strong ping pong effect between stress and sleep where one can cause more of the other.
Unfortunately, stress can change how people make decisions:
- It can affect your ability to make new decisions and adapt to change
- Stress typically increases risk-taking
- When stressed you may sometimes pay more attention to the upside of a possible outcome
Hopefully after sleeping on it, you’ll wake up less stressed, more relaxed, and can make a more balanced decision.
4) Work the problem while you’re asleep
Sleep helps your brain process stuff. We’ve all heard stories or even personally experienced getting a good idea after a good night’s sleep.
That means while you’re sleeping on your decision it can help facilitate problem solving.
5) Sleeping on it will buy you some time
You don’t want to be rushed into making a bad decision, especially if it’s in the heat of the moment.
Sometimes, a little extra time allows you to think things through some more and come to a better decision. You may realize there’s a resource, person, or something else you haven’t considered.
What to try if you’ve decided to sleep on it but can’t fall asleep
Okay, it should be clear by now why sometimes the best thing you can do is to sleep on it. You might be thinking easier said than done.
We’ve all had nights when a decision is pretty heavy on the mind and it’s a struggle to fall asleep. After all, how’s one to settle down when your mind is racing through the possibilities or you’re feeling unsettled about things?
The good news is they’re plenty of practical things that can make the transition to sleep easier if you’re having a tough night:
1) Make sure your bedroom is fine tuned for sleep
A poor environment will make sleep even harder to come by. As a rule, your sleeping space should be dark, quiet, and cool.
2) Avoid making things worse
Doing the wrong activities in the evening to pass the time can actually make it harder to fall asleep. What you want to avoid is anything too stimulating that may get you even more wired up.
Yes, I’m talking things like social media, suspenseful movies, and watching the news.
Also, you want to avoid eating foods that interfere with sleep such as caffeinated beverages, alcohol, and unhealthy snacks.
And stay away from bright electronic screens (TVs, tablets, smartphone) – the bright light signals your brain it’s time to wake up.
3) Do a sleep-friend activity that can aid the transition to sleep
There are plenty of ways to unwind at bedtime that can help prepare your mind and body for sleep. Among your options are light reading, light music, relaxation exercises, and working on a puzzle.
4) Write it down
Sometimes the best way to keep those squirrels from running around your head and keeping you up is to get your thoughts on paper.
Your options include:
Making a list
Try outlining the issues, pros & cons, and possible outcomes. This can give you a clearer idea of what you’re up against and getting organized sometimes provides a sense of peace.
It’s a great way to sort through feelings and jumbled thoughts. Learn more
