Good & bad moods

A stressful working day, a hectic family life or the dark, cold days of winter can sometimes have quite an impact on our mood and make it difficult for us to get through the day in a good mood and with optimism. Day after day, our psyche reacts to numerous internal and external stimuli that arouse emotions and influence our well-being and state of mind. But our sleep can also have an impact on our moods. After all, the fact that we ask bad-tempered people if they "got up on the wrong side of the bed" in the morning is no coincidence.

Aufbau des Gehirns: Das Limbische System

The basis of our emotional reactions, feelings and sensations lies in our brain, more precisely in the so-called limbic system. This is where internal and external stimuli are registered and processed, linked to memories, for example, and an emotional reaction is triggered by the release of various hormones. The reward system in our brain is also particularly decisive for our state of mind. By experiencing positive situations or events, the messenger substances dopamine and serotonin, also known as happiness hormones, are released and we experience positive feelings such as happiness, joy or optimism. Serotonin also has a calming effect on our nerves and well-being, promotes inner balance and, in a roundabout way, also promotes our sleep.

The psyche during sleep

Our reward systems and the emotional processing of information are strongly related to sleep. Especially in the deep sleep phases our body and brain regenerate. Energy stores are replenished, experiences and information are processed and stored in the brain. An undisturbed, peaceful sleep is therefore not only of great importance for the healthy functioning of our organism, but also decisive for our mental health and our emotional state.

And a healthy sleep-wake rhythm is also good for our mood, which in turn has a positive effect on sleep itself. This is because during the day the body releases more of the happy hormone serotonin, which promotes a positive mood, calms our nervous system and counteracts negative feelings caused by stress or overstimulation. Towards evening, serotonin is then converted into the sleep hormone melatonin, which makes us tired and allows us to sleep. During the night our body is then in a performance low, the body temperature drops and the serotonin level drops. This is how the famous nocturnal low mood arises, which then manifests itself in nocturnal waking phases through negative thoughts or extensive brooding.

How poor sleep harms the mood

Scientific studies have shown that our mood is influenced by how long we sleep, but especially by the quality of our sleep. What is the reason for this?

Lack of sleep

Lack of sleep and frequent sleep interruptions prevent our regeneration from running optimally and lead to us not getting enough deep sleep. This puts the body under stress, whereupon our cortisol levels rise, causing numerous negative consequences for our health and well-being. We are tired, have less energy, are more easily irritated and less able to concentrate. This, of course, clouds our mood the next day and can, in turn, have a negative impact on sleep by putting us under pressure and making it difficult to relax.

Sleep disorders

Interrupted and disturbed night sleep in particular can have an impact on the mind and our emotional awareness. Frequent awakenings interfere with the flow of natural sleep cycles, reducing the amount of deep sleep. Various studies prove that frequent awakenings had a negative effect on the mood of the subjects, causing them to be less receptive to positive stimuli, but all the more receptive to negative stimuli. Those subjects whose sleep was interrupted several times during the night were less sensitive to positive emotions such as joy and happiness and, on the contrary, reacted more strongly to negative sensations such as anger or fear. It also became clear that the test subjects were unable to perceive and enjoy positive experiences properly.

However, it is also crucial how we spend our waking phases at night. If it is difficult to fall asleep again, the famous carousel of thoughts often begins or we put ourselves under pressure, which again increases the stress level and additionally prevents a peaceful sleep.

Too much sleep

But too much sleep can also harm our mood and even worsen depressive moods. Because in addition to sufficient deep sleep, dream sleep (REM sleep), in which our brain in particular becomes active, is an important basis for healthy brain function and a stable psyche. Studies even show that people who suffer from sleep disorders have a fivefold higher risk of developing depression.

Start the day positively

Good sleep = good mood? Sufficient and, above all, undisturbed sleep is definitely a decisive factor in how we feel during the day. With a healthy sleep at night, sufficient daylight, exercise in the fresh air and positive experiences during the day, you can also support the release of happiness hormones as well as falling asleep in the evening. And your daily diet and vitamin supply can also help you to keep your hormones in balance, sleep better and thus maintain a good mood. This way, you can relax into sleep in the evening and start the day balanced, optimistic and in a good mood.
