Let us set a very common scene for you quickly. You prepare your bedroom for sleepy time, turning on the fan, fluffing your pillow, and making sure everything else is just right. After you lie down and turn off the lights, you realize that you are alone with your own thoughts. Perhaps you spiral out of control about diseases that you don’t have, financial hardships, family members, and other stupid things that you don’t need to think about when going to bed.
When you are in this situation, it feels like you cannot turn off your brain. Before you know it, you look at your phone and it is three in the morning. You have to wake up in a few hours to start the day, and that only propels your anxiety to a whole other level. The next thing you know, the sun is peaking through your curtains and it is time for you to greet the day, as much as you don’t want to.
The goal is to get peaceful and restful sleep every night so that you feel refreshed when you wake up. What is the mind doing at night and how can you shut it down?
The Science Of Sleep
To give you a quick overview, you must know about two thought networks. The first is the central executive network (CEN) and the second is the default mode network (DMN). The former runs when you focus your attention on something, making it purposeful and task-oriented. The latter runs whenever the CEN is off and it is the general mental chatter that you hear all day long. DMN is essentially your stream of consciousness.
The bad news is that the DMN is negatively biased, so it loves to point out the worst qualities you have. It brings up all of your most painful or embarrassing memories. Sleep experts note that one of the most critical stages of falling asleep is uncoupling the DMN. That basically means that you have to get areas of the brain to stop talking to each other. The CEN is tired at night, so it becomes more difficult to get the DMN to turn off because your ability to focus decreases.
If you are uptight and stressed, the DMN may also not want to turn off. Researchers at Brown University watched people fall asleep in a brain scanner to better understand why people have a hard time going to sleep at hotels. They observed that the left hemisphere of the DMN remained more active than the rest of the brain during the first night. It woke up other areas of the brain when something unexpected happened, such as a hotel door closing or a voice in the hall. The more alert the DMN was to the outside world during the study, the longer it took for people to fall asleep. It was the DMN that kept them awake and alert when they really wanted to be asleep.
How To Train Your DMN For Better Sleep
Now that you have a better understanding of how the brain keeps you up at night, you can learn ways to override the DMN. The following techniques will help you fall asleep. Experiment with them and see which one works best for you.
Read Something Uninteresting
If your DMN will not be quiet, find something neutral, boring, or uninteresting to read or listen to. Some people suggest watching something boring, but it’s best to limit blue light exposure before bed. Reading is great, but it is a big leap to go from an anxiety spell to a book. In that instance, an audiobook or podcast might be a better option. Perhaps an astronomer talking about Venus’ relationship to a black hole might soothe you and help you drift off to sleep.
Force Your Mind To Remember Something
One of the scariest parts about going to sleep is the actual going-to-sleep part. The reason for that is because so many people struggle with sleep. That is true whether you are beginning to go to bed or trying to fall back asleep after waking up in the middle of the night. When you actively ask the brain to do something, you prevent the DMN from the chaos it causes. Try to remember something that you read or listened to from the previous tip. You can also try to remember the plot of a movie or book that you read/watched recently. Give yourself a cognitive task while falling asleep and the DMN won’t steal the show!
Breathe
It is very easy to feel stressed out when the DMN gets caught up in its worries and insecurities. You may feel your breathing become shallow and your muscles can clench. If the DMN is firing on all cylinders, you may clench your jaw and experience nightmares. To help calm the DMN, try soothing the body with some deep breaths. You can also engage in breathing techniques that promote more restful sleep.
Take A Hot Bath
As a quick note, do not take a hot bath right before you are about to go to sleep. Hop in the bath to soak about two hours before bedtime. Research shows that a hot bath or shower at night can help people fall asleep almost as fast as people who take Ambien. Why does a hot bath or shower help the body shut down? In the hours leading up to bedtime, the body temperature naturally drops. A hot bath or shower simulates this process, helping to improve sleep duration and quality.
