When we experience hardships it can be difficult to stay positive. It’s not easy to stay optimistic when we notice our thoughts steer negative, but most of us are always hoping to achieve a certain level of positivity. First of all, why do we fall into our negative thoughts? Second of all, how does sleep help with our negative thoughts?

3 Common Reasons of Negativity

According to a study at a university, there are 4 elements that create negative thinking: Regret and Shame, Negative Expressions, Lack of Confidence, and Criticism Towards Others. If we sum it up, the following 3 reasons are the most common triggers for negative thinking.

Severe Long-Term Stress

Stress can be a direct cause of negativity. When we mess up at work/school or can’t perform well, negativity takes over our minds, making less room for positivity to grow. If we surround ourselves with negative people, sometimes we end up being heavily influenced by them too.

Past Traumatic Experiences

Past trauma can impact us in many ways. A person full of optimism and positivity can suddenly change negatively due to shocking incidents. Some people can fall into a negative trap where they can’t believe in anyone after experiencing betrayal from someone they used to trust.

Hormonal Imbalance Due To Poor Lifstyle Choices

A neurological chemical called serotonin has to do a lot with our emotional control and stability. A lack of serotonin not only makes us less energetic, but it can also make us negative too. For your body to properly produce serotonin, a stress-free lifestyle with exercise, a healthy diet, and sunlight becomes crucial. If we can shift our lifestyle with healthier lifestyle habits that promote serotonin, that can push our minds back towards positivity.

3 Reasons Sleep Heals Negativity

Typically, if the cause of our problems is clear, we’d have to fix that first. However, causes such as past trauma or long-term stress cannot be fixed overnight and that can feel like a struggle. Therefore, we advise that you start easy with getting plenty of sleep. In this section, we’ll explain how sleep can heal negativity within our minds.

It Heals the Physical Body and Brain

The brain can rest and condition the body’s hormonal balance when it goes to sleep. A well-balanced hormonal function can fight negativity and build stress resilience towards the incoming negativity we experience.

The body needs to feel energized enough before we start exercising towards a healthy serotonin function. Sleep also helps our whole body restore itself. Without fundamental sleep, it’s hard to make the change we desire.

Leads To Better Lifstyle Habits

A structured sleeping schedule, sunlight, and a healthy diet all contribute towards getting rid of our negativity. A good night’s rest promotes serotonin secretion which helps us back to positivity. Good sleep also helps us stay efficient during the day. Most of us have pulled all-nighters during the weekday only to try and catch up on sleep during the weekends. We can start working on positivity today, just by starting off a healthy sleeping schedule.

Stops The Negativity Loop

Once we fall into a negativity loop our problems seem infinitely larger than what they are. We need to reset our minds so that we can shift gears towards positivity. To easily do this, we recommend sleep.

When we sleep, our thoughts are forced to shut down and we can leave from thinking so much. This gives us the capability to look at things more objectively and calmly when we wake up.
