Sleep Deprivation: Tired of Being Tired? The Truth About Caffeine and Energy

Sleep Deprived? Coffee Might Not Help You Power Through Like You Think
A new study looked at caffeine, humanity's favorite pick-me-up. While coffee may help you stay awake after a bad night's sleep, it won't necessarily help you get everything done.
Over 275 people participated in the study. They were kept awake and then given caffeine before doing a couple tasks. Researchers from Michigan State University's Sleep Lab wanted to see if coffee could help overcome mental tiredness from lack of sleep. Unfortunately, it doesn't seem like caffeine can do the trick. The participants struggled on the harder of the two tasks they were given.
Even though coffee helped them finish an easy attention-based task, they still had trouble with both tasks overall. Especially hard was a "placekeeping" challenge where they had to do things in the right order without mixing anything up. Caffeine didn't provide much of a boost for the more difficult job.
The findings indicate that while coffee can help you stay up and do simple things when tired, it probably won't protect you from the types of mistakes common when sleeping hours are low. This is important to know in jobs like healthcare that require careful task completion when someone may be sleepy.
The study leader, Kimberly Fenn, spilled the tea (pun intended!):
They were hoping caffeine would be a superhero for sleep-deprived folks who have important jobs to do, like surgeons, pilots, and police officers (think operating on someone, landing a plane, or catching a criminal – all while sleep-deprived!). Basically, if caffeine could help them avoid making big mistakes, that would be a game-changer. Unfortunately, the study showed sleep is still king (or queen!). So, the big takeaway? Make sure you catch those Zzz's!
Can you fix sleep deprivation? Man, sleep deprivation is no joke! It really messes with your brain and body. The good news is there are some things you can do to help fix it.
The obvious one is just getting more sleep. Easier said than done sometimes, I know. But try going to bed earlier or taking a nap if you can. Setting a bedtime routine can help cue your body that it's time to sleep too.
Caffeine in moderation may provide a little pick-me-up, but don't rely on it to solve low energy or brain fog from lack of sleep. Getting outside in natural light during the day can also help reset your internal clock.
Beyond sleeping more, reducing stress is also important. Stress hormones make it harder to fall and stay asleep. Try relaxing activities before bed like reading or yoga. Limit screen time too, since blue light suppresses melatonin.
It may take a few nights but being consistent with better sleep habits should start to leave you feeling more refreshed. And remember to be kind to yourself - we've all battled sleep deprivation at some point! With some patience you'll bounce back.
How many hours is sleep deprivation?
There's no definitive cutoff, but generally sleep deprivation is considered:
-
Not enough shut-eye? Adults need at least 7 hours, experts say: 7-9 hours of sleep is key
-
For occasional loss of sleep, going more than 24 hours without sleep is considered deprivation. Even missing just 1-2 hours can have negative effects.
-
Teenagers require even more sleep - 8-10 hours per night on average. Deprivation for them is under 8 hours.
- Deprivation is also relative to individual needs. Some people naturally need 6 hours while others need 9 to feel fully rested. Not getting your personal required amount regularly leads to deprivation.
The effects of sleep deprivation tend to accumulate over time as well. Getting just a few hours less than your normal amount every night can impair functions almost as much as one all-nighter over 24 hours. And chronic short sleep, even of 6 hours or slightly more, still increases health and safety risks long-term.
So in summary - under 7 hours regularly or over 24 hours without sleep would generally be considered the threshold where sleep deprivation negatively impacts people. But our individual needs vary.
Can you get used to being sleep deprived? Yeah, it is possible to develop some tolerance to sleep deprivation over time, but it never fully goes away and comes with health risks. Here are a few key points:
-
Your brain may adapt by becoming more efficient at certain tasks with chronic lack of sleep. Performance will still deteriorate compared to being well-rested.
-
You can learn to better function and think you feel fine, but objectively your reaction time, judgment, mood, etc are being negatively impacted.
-
No one truly adjusts to the biological need for sleep. Deprivation still accumulates debt that must be repaid with extra sleep eventually.
-
Short-term adaptations come at a cost of increased health risks like weight gain, diabetes, heart disease and depression with long-term insufficient sleep.
-
Even if you feel you adjust, lapses in concentration can happen suddenly like microsleep. Driving tired is extremely dangerous.
- Chronic sleep deprivation is linked to increased risk of premature death. The body pays a price for long-term lack of restorative rest.
So in summary - we can develop some psychological tolerance through necessary adjustment, but the impacts on well-being are very real. It's never safe or advised to remain sleep deprived long-term.
How do you function when sleep deprived?
Here are some tips for functioning when sleep deprived:
-
Caffeine in moderation can help, but don't rely on it. Too much can backfire.
-
Take micro naps of 5-10 minutes if possible to refresh. Set an alarm.
-
Stimulate your senses with music, mint gum, splashing cold water on your face.
-
Avoid complex tasks if you can. Stick to more routine/repetitive work that doesn't require deep thinking.
-
Move around and change your posture frequently to stay engaged. Go for short walks.
-
Eat healthy, nutritious snacks full of proteins/complex carbs that sustain energy.
-
Buddy up with a well-rested friend if safety is critical like driving long distances.
-
Rely on checklists, technology aids like calendars more than memory if very deprived.
-
Admit limits and take breaks before exhaustion sets in to stay safe.
-
Prioritize work that has deadlines/high stakes first, socialize/hobbies later.
- Make sure to get extra sleep on non-work days to pay back debt incurred.
The key is compensating through aids and acknowledging decreased capacity so you don't put yourself or others at risk. This state can't last indefinitely without health consequences.
Conclusion
coffee is great in moderation for providing a small boost when I'm feeling tired. On nights when I don't get enough sleep, having one cup in the morning helps me feel a bit more alert and able to focus for a couple hours. The caffeine perks me up just enough to make it through my morning routine.
That said, I try not to rely on coffee as my only solution for fighting sleepiness, because I've found the crash afterwards makes me even more drained. Overdoing the drinks can make me anxious later. So I see it more as a temporary bandaid rather than a real fix for the underlying sleep debt I've built up.
The only times I'll have multiple cups is if I really need to cram in some work or studying for a short period of time. But on those days, I try to nap or relax extra hard afterwards to make up for it. Overall, I think getting sufficient quality sleep is far superior to just loading up on caffeine whenever I'm tired.
Personally, coffee gives my mental batteries a little boost in the short term but never fully makes up for the clarity and focus I get from quality rest. So while coffee helps in a pinch, I still make sleep a top priority for feeling my best all day long.
