Is it me, or does it feel like so much of what you read online about the consequences of sleep deprivation focuses on its long-term impact?
It makes sense in some ways.
After all, chronic sleep loss is a major problem.
Consider the infamous case of radio DJ Peter Tripp.  In 1959, he went over 8 days without sleep as part of a media stunt. He suffered serious hallucinations, extreme paranoia, and psychological scars that some reported to last beyond the experiment.
What about the short-term effects though?
As anyone who’s ever pulled an all-nighter knows, even a single night of bad sleep can have very real consequences too. Important as it is to think long-term, the magic really happens when we start protecting each and every night.
To highlight why that’s the case, here’s what happens after just one night of poor sleep…
The first and most obvious effect is on your energy levels. Depending on the extent of the deprivation, you might feel general tiredness throughout the day.
Your body feels heavy, your mind feels slow, and keeping your eyes open can seem impossible. All you really want to do is lie down in bed, curl up under the covers, and catch up on some rest.
In worst-case scenarios, fatigue caused by sleep loss can lead to mistakes and ensuing accidents. Fun (if you can call it that) fact: alongside other infamous disasters, this contributed to the 1986 nuclear disaster at Chernobyl, where the operators were reportedly sleep-deprived.
Your ability to focus suffers when you’re that tired too. Concentrating fully on daily tasks becomes a chore, which makes everything take ten times longer than it probably should. As the composer, John Cage once said, “Sleep’s what we need. It produces an emptiness in us into which sooner or later energies flow.”
Remaining calm and patient takes energy that you don’t always have after a poor night’s sleep. That’s why it’s so much harder to keep your emotions in check.
Like a toddler having a tantrum, there’s no filter anymore. As this study from Iowa State University showed, any anger that you’d usually be able to control rises straight to the surface. Even after a few hours less sleep than usual, your likelihood of becoming snappy, grouchy, and difficult to be around can increase.
Without it, it’s as if your mind’s shrouded in a thick fog; finding solutions to mental problems is like wading through mud. Your short-term memory, attention span, and general cognition are all impaired.
In a recent University of Berkeley study, 18 healthy adults went without sleep for a single night. The next day, they showed a 30% increase in anxiety levels. The study concluded with, “Our findings emphasize sleep as a novel therapeutic target for the amelioration of anxiety in non-clinical and clinical populations.”
Another interesting finding comes from their brain scans, which showed their amygdalae firing on all cylinders, yet relatively little activity in their medial frontal cortices. Given that the amygdala controls our fear response and the frontal cortex regulates emotions, this points to the idea that sleep loss can wreak havoc on our emotional lives!
Below are various breathing and stretching exercises to help reduce stress and anxiety. You can use this exercise anytime you find yourself needing to relax and re-center.
Did you know that people who sleep less than 6 hours each night tend to have a higher BMI than those logging above the 6-hour nightly mark?
It sounds crazy, but it’s because our bodies release hormones that, among other things, help suppress our appetite. In other words, you’re more likely to get the munchies if you don’t sleep enough.

Knowing about the long-term ramifications of sleep loss is all well and good.
When it comes to sleep health, though, the best approach is to take it a night at a time. You’ll avoid everything from the unhelpful fall-out of a single poor sleep to the most debilitating effects of chronic sleep deprivation.
