As a leader, taking good care of my health is important for me and my family and to set the tone. I cannot ask others to do what I won’t do. To that end, the acts of exercising and eating well are part of my routine. I live a busy life, building a business, leading teams, and being an involved parent and loving spouse. There is never enough time to do everything I want to do.
It’s easy to let sleep slide by going to bed a little late so I can finish a project or getting up early to catch a flight. I recently learned that getting enough sleep is much more important than I had previously believed.
I thought sleep was important so I could function well and be at my best during the day. I also thought that I was good at working through a day when I was tired. I’ve learned a lot about sleep deprivation over the past week. I want to share some of what I learned because I know it’s helping me improve.
One of the facts I learned was so shocking I wanted to reject it at first. Researchers have found that we are often unaware of the cognitive effects of sleep deprivation that impair performance and we tend to be more positive of the rightness of our thoughts when we are sleep deprived, especially when we are wrong.
As I write that, it sounds as if I am describing drunken behavior, doesn’t it? The effects of sleep deprivation cause problems that are the equivalent of being intoxicated.
Sleep Impairment Affects Your Performance
The scary part of the sleep research is that when we are partially sleep-deprived, we feel normal. We don’t recognize how impaired we are from lack of sleep. We can be as impaired as we would be from losing two consecutive nights of sleep and feel normal when it is a cumulative effect from repeated sleep detriments. Researchers have compared the effects of legal intoxication to the effects of sleep deprivation and found that partially sleep-deprived people can be as impaired as someone who is legally intoxicated and feel normal.
They also found that individuals who are partially sleep-deprived are more likely to experience conflicts they have difficulty resolving and they are 70% more likely to be involved in an accident than someone who is well-rested.
That was a wake-up call. I wouldn’t go to work intoxicated. I’m sure you wouldn’t either. I didn’t know that working after a week of not getting enough sleep was equivalent to working while intoxicated. I’ve done that. You probably have, too.
At first, I wanted to reject this new information. In the past, I kept functioning for weeks when I didn’t get a full night’s sleep. Now I realize I wanted to reject the empirical research because I felt like I was functioning normally, just like the researchers described. But I wasn’t functioning normally. I reviewed my track record and it revealed a way that my prior experiences proved the truth of the research to me.
Listen To Your Gut
Like most leaders, I understand the value of my gut to let me know when I’m making the right decision.
It sounds weird to trust the gut, unscientific, and irrationally weird. Weird, but reliable, is how I see gut instinct. In my recent article, (Intuition and Decision Making) I described how researchers are moving away from the idea that humans are logical.
I have done well trusting my gut most of the time. When I looked back at the times when my gut failed me, I realized that it syncs up with this research. When I hadn’t had enough sleep is when I made gut-based decisions that didn’t work out well. Sometimes, I made a decision and didn’t act on it and later wondered why I thought it was a good idea. Those situations make more sense when I evaluate how much sleep I’d had before I made the decisions that later seemed nonsensical.
Although I trust my gut because it has proven accurate more times than not, what I’ve learned about sleep deprivation helps me know more about when to trust it and when not to make decisions. Because sleep deprivation messes with the frontal lobe’s cognitive function including the ability to make decisions, memory, and our ability to exert self-control, when I’m sleep deprived, I am not going to make important decisions.
How Do We Know We’re Sleep Deprived?
There are a few indirect ways to know. Partial sleep deprivation makes us more irritable. We are more likely to make mountains out of molehills and let little things disturb our equilibrium. We are also more likely to be in a lower mood than normal. And, finally, we are more likely to feel sleepy during the daytime.
If I notice myself becoming irritated by things that I would usually shrug off, I will stop and ask myself if I am well-rested. If I notice I am out of sorts, I will ask the same question.
When I’m sleepy during the day, I usually reach for a pick-me-up with caffeine and a snack. While I might still do that if I need to keep going if I can take a power nap, that might be a better choice as long as I don’t sleep so long that I have trouble going to sleep that night. If I can’t take a nap, I can rearrange my evening so that I get to bed earlier.
I’ll do this so that I am better today and tomorrow. Sleep deprivation doesn’t just make us less capable today. Sleep deprivation is associated with serious long-term problems—it is as unhealthy as not exercising and eating poorly. The risk of developing heart disease, type 2 diabetes, cancer, mental health problems, and early mortality increases when we don’t get enough sleep on a regular basis.
Naps that last between 20 and 40 minutes taken before late afternoon provided the most benefit.
