Last time, we saw that sleep is when your body repairs itself and your brain sorts and stores the day. This time, we’ll look at what happens when you don’t get enough.Some years ago, I woke up at 2:30 one morning with a big project on my mind. I couldn’t get back to sleep. After about an hour, I went into my study and outlined the project on paper, hoping that would quiet my thoughts.It didn’t. I never did get back to sleep before the alarm went off at 6:15. That's when I had to get ready to go to work. One bad night is an inconvenience. The trouble starts when short nights become a pattern, and for many of us, they have.What Short Sleep Does to Your MindCara Palmer and her colleagues at Montana State University pooled the results of 154 experiments in which researchers cut people’s sleep and then measured their emotions. (A pooled analysis like this is called a meta-analysis.) About 5,700 people took part. Published in Psychological Bulletin in 2024, the findings were consistent: people who lost sleep had less positive mood and more anxiety.Here’s what caught my attention. The dip in positive mood showed up even after fairly small losses, such as staying up an hour or two late. You don’t need an all-nighter to feel less like yourself.Thinking suffers too. A CDC survey found that adults sleeping under seven hours were more likely to report trouble concentrating.<h2 id="1a4b7059-3214-4c53-8aa6-b14f31b3a270" data-toc-id="1a4b7059-3214-4c53-8aa6-b14f31b3a270" style="text-align: left; font-size: 24px; line-height: 1.2;">What Short Sleep Does to Your Body</h2>The CDC links insufficient sleep to chronic conditions including diabetes, cardiovascular disease, obesity, and depression. “Linked” is the careful word here. Sleep loss is one factor among several.The most immediate danger is on the road. CDC data show that drowsy-driving crashes are more likely to cause injuries and deaths than other crashes. Drivers who sleep six hours or less are more likely to report nodding off at the wheel. If you feel yourself fading while driving, pull over.<h2 id="ca343447-dc6c-43c5-a3ec-5cc2077778fa" data-toc-id="ca343447-dc6c-43c5-a3ec-5cc2077778fa" style="text-align: left; font-size: 24px; line-height: 1.2;">A Loop You Can’t Think Your Way Out Of</h2>Stress makes it harder to sleep. Short sleep makes you more reactive, so ordinary things feel more stressful. Then you sleep worse.Around it goes. This is one reason I keep coming back to balance: when stress is a problem, balance is the solution. Sleep is one of the first places balance has to show up.<h2 id="5a0f6549-9ef2-4a75-a3c0-a8c76f201368" data-toc-id="5a0f6549-9ef2-4a75-a3c0-a8c76f201368" style="text-align: left; font-size: 24px; line-height: 1.2;">What Scripture Adds</h2>King David wrote, “In peace I will both lie down and sleep; for you alone, O LORD, make me dwell in safety.” (Psalm 4:8 ESV) He wrote under pressure from people who opposed him, yet he tied sleep to peace and to trusting God for safety.If you’re lying awake tonight, that is not proof your faith is weak. Your body may be asking for help.<h2 id="c278efe5-d936-4e0b-8c00-ac722bd4d4b3" data-toc-id="c278efe5-d936-4e0b-8c00-ac722bd4d4b3" style="text-align: left; font-size: 24px; line-height: 1.2;">One Thing to Try This Week</h2>After your next short night, jot down what changed by mid-afternoon. Seeing it on paper makes the cost harder to ignore.Next time, we’ll look at how much sleep you actually need. It’s probably more than you’ve been guessing.<h2 id="e83d28e6-7389-41bc-ba1b-071966623eb8" data-toc-id="e83d28e6-7389-41bc-ba1b-071966623eb8" style="text-align: left; font-size: 24px; line-height: 1.2;">What Slips First for You?</h2>After a short night, what’s the first thing to slip for you?
