Many people believe that expressing anger serves no purpose, and it’s best left unexpressed. However, people with this perspective typically end up feeling resentful of their loved ones. They never express their anger, so it just simmers unproductively. The resentment builds, and the relationship deteriorates.
In some cases, anger is better left unexpressed. It’s wrong to express anger in a way that is physically or emotionally harmful towards the person with whom you are angry, but if you know how to communicate in a healthy manner, then expressing your anger can lead to a more fulfilling, honest and authentic relationship.
What many people don’t know is that the idea of not going to bed angry actually comes from the Bible. In Ephesians 4:26, it states; Be ye angry, and sin not: let not the sun go down upon your wrath.
Ephesians 4 is clear: resolve any conflict before drifting into REM.
Going to bed angry has a profound effect on your brain and subconscious. A study in the Journal of Neuroscience revealed that going to sleep after experiencing anger (or any negative emotion) helps the negative emotion to lodge permanently in the brain. The brain activity that occurs while we sleep “protects” the anger and permanently embeds it our emotions.
If you have a fight with your spouse, don’t sleep it off. Instead, talk it out and choose to resolve the conflict – even if you must agree to disagree, let go of the negative emotions so that you can rest.
