The "Late Night" Mind: Why Everything Feels Worse at Night

It’s 1 AM, you’re lying in bed, and you find yourself incapable of sleeping. You’ve tried doomscrolling to distract yourself from the swarm of your thoughts, but it’s ultimately unavoidable. Suddenly, every embarrassing moment you’ve had, every mistake you’ve made, and every worry about the future floods into your brain like a bright light, unable to turn off the switch.

But why, exactly, does this happen in the first place?

At night, your body begins to transition into its “sleep mode” through the circadian rhythm, the body’s internal 24-hour clock that regulates the sleep-wake cycle. Melatonin levels increase, making you feel tired while at the same time lowering alertness and cognitive control. Furthermore, the activity of the prefrontal cortex, the part of your brain responsible for decision-making and emotional regulation, is heavily reduced as well. The amygdala, an area involved in deep emotional processing, becomes much more reactive due to this decline. This imbalance highlights a point in time where your brain’s emotional responses are stronger, yet the ability to regulate these responses is much weaker. This results in our thoughts spiraling and intensifying into more negative ones.

Nighttime also shifts the environment around you. During the day, our attention is constantly preoccupied, whether that’s focusing on schoolwork, family, friends, or hobbies we enjoy doing. But when we’re lying in our bed, trying to go to sleep, our brain immediately goes towards the thoughts we were trying to avoid during the day. The brain shifts inwards, leading to an emphasis on lingering problems and worries, like concerns about the future or regrets of the past. Because we are tired, our brain also wants to perceive these thoughts as more negative, since we are least likely to try to put things into perspective without a well-functioning prefrontal cortex. 

These late-night thoughts are also heavily felt because there are fewer triggers around us, intensifying our negative thoughts and emotions. Since our prefrontal cortex activity is diminished while our amygdala’s activity is heightened, our critical thinking skills are heavily reduced, making it much harder to contain these thoughts and process our emotions effectively.

Now you might be wondering how you can manage this “late-night effect.” Fortunately, it is not all that complex. Here are some insightful tips to help reduce these negative thoughts and keep your brain from infinitely spiraling.

1. Keep a solid structure before bed: Having a consistent schedule for “winding down” helps reduce our tendency to overthink. Trying a simple self-care routine, watching your favorite show, or reading an interesting book can help with this.

2. Write down your thoughts: Though this may seem cheesy, keeping a diary or journal and consistently writing in it every night can help stop your thoughts from spiraling. Getting it all out in writing may stop you from thinking about it later in the night since you’ve already gotten it off your chest.

3. Interrupt the spiraling: When you find yourself unable to think of anything else, get up from your bed, get a drink of water, or even just walk around your room. It can help break this loop and get you to clear your mind.

4. Avoid your phone: While tempting, scrolling on your phone is a huge mistake. You think you’re distracting yourself, but in reality, you’re piling these thoughts up even more and filling your brain with negative information.

5. Be kinder to yourself: This late-night version that you have of yourself is not truly you. We are much harsher to ourselves than anyone else, but we have to remember to be kinder. Think of it this way — you would never treat your loved ones the way you’re treating yourself right now.

Late-night thoughts can feel extremely intense, but they are hardly reliable. They are shaped by our high melatonin levels and reduced activity in certain areas of our brain. So, instead of treating these thoughts like they truly mean something, try viewing them in a different light. Seeing these thoughts from a new perspective helps us respond with less self-judgment and more self-love.
