Why all-nighters dont work

If you have ever been in a situation with a tough deadline, then you may be familiar with an "all-nighter". An all-nighter is what happens when someone voluntarily skips sleep and stays up to try and cram in last second information. If you're a student studying, you may pull an all-nighter before a big exam to squeeze in a few extra hours of studying. If you have a big presentation, then you may stay up to put the last finishing touches on it. Whatever the reason may be, pulling all-nighters may actually not have the benefits you are seeking. Keep reading to find out why all-nighters are counterproductive to your efforts. 

Sleep deprivation and memory

When you decide to stay up all night to better prepare for something, you may actually find that you are not better preparing yourself for anything except several moments of "Oh, I know I know it..." 

When you deprive your mind of sleep, your brain is unable to get the rest it needs to consolidate memory. If you're studying or preparing for a presentation, this means that a lack of sleep doesn't give you the chance to consolidate your memories. Consolidation is important for recall, because without it, it simply floats away and you can't remember. 

Sleep deprivation also has negative effects on your cognition, working memory, and attention. When you wake up at 8 am, pull an all-nighter until the next day at 8 am, you have stayed up for a full 24-hour period. Until you get sleep, your brain is paying the price of that sleep deprivation. Research has shown that those who are sleep deprived have similar cognitive function to someone who is drunk. 

Your working memory isn't functioning meaning it could take you longer to process things. If you're going into an exam or an important presentation, the last thing you want is to feel as if you're buffering when trying to work your way through a question. 

Sleep deprivation and mood 

Not only does sleep deprivation have a negative impact on your memory and cognition, but also on your mood. When you are tired, your brain is just focused on keeping you alive. Anything extra is a far reach. 

If you have a negative mood, then you may have trouble coming up with the energy required to get through your test or presentation. Your self-esteem and patience may also be negatively impacted, as well as your motivation. 

Sleepless nights have also been tied to higher feelings of anxiety due to the increased level of cortisol in the body. Not only will you be tired the next day, but you will also struggle with remaining calm. 

How all-nighters interrupt your sleep schedule 

Sleep deprivation is not just a problem for your cognition and mood. All-nighters can seriously mess up your sleep schedule. It is highly recommended that you keep a similar sleep schedule all the time. This helps with sleep hygiene and putting your mind and body in the habit of going to sleep at a certain time. 

When you pull an all-nighter, you slash through this routine as your clock is all thrown off. If this becomes a regular activity, then you are at risk for a long road of sleep issues. 

What to do if you have to pull an all-nighter

Sometimes, all nighters are just unavoidable. If you must pull an all-nighter, or just happen to because something (other than insomnia) kept you from getting to sleep, there are a few things you can do to try and combat the negative impacts of an all-nighter. 

Drinking caffeine and water can help you fight the desire to go to sleep. Caffeine is a stimulant that helps to wake you up, and water will help you avoid dehydration, as well as cause you to take multiple bathroom breaks. 

Keeping the lights on will definitely help you as well. Light interrupts the production of melatonin, helping you to stay awake. Chewing gum and staying active are also ways to help you stay awake. Anything that interrupts your attempts to go to sleep will help you stay awake. 

If you do have to pull an all-nighter, make sure you are safe. Avoid driving or operating heavy machinery. In order to preserve your sleep schedule, avoid that extra long afternoon nap.

It may negatively impact your efforts to go to sleep that following night, leading to continued sleep issues. Also minimize the amount of time that you are sleep deprived.
