If you're depressed, you should exercise for 15 minutes a day, such as walking on a bicycle
Receiving sunlight for 30 minutes (serotonin production and melatonin secretion are promoted) and regular living can prevent it from worsening.
Serotonin and norepinephrine must be involved, but dopamine and other neurochemicals are also involved. Depression is affected by a wide variety of neurotransmitters.

Serotonin - willpower, motivation for activity. Improves mood.
Norepinephrine - enhances thinking, concentration, and ability to cope with stress.
Dopamine - is essential to increase pleasure and break bad habits.
Oxytocin - promotes trust, love, and solidarity and reduces anxiety.
Gabba - relieves tension and reduces anxiety.
Melatonin - improves sleep quality.
Endorphins - soothe pain and give you elevated feelings.
Endocannabinoids - boost appetite and increase serenity and well-being.

the hippocampus of memory
Happy Memory Storage. In a state of depression, the hippocampus negatively stores memories. Context-dependent memory is remembering things closely related to your current situation more quickly. In addition to being abnormally active, the hippocampus becomes smaller in size. The reason is most likely the result of chronic stress, which can damage or kill neurons. Fortunately, the hippocampus can create new neurons.
