This is What Happens When You Sing Every Day

Scientific concepts / discoveries / nature phenomena mentioned

Social development

• Children who sing regularly in school (e.g., choir or class singing) show better social skills and connect with other kids faster than children who don’t sing.

Emotional regulation

• Regular singing is claimed to help emotionally regulate—improving how people handle emotional states.
• This is described as especially helpful during teenage years/pubertal emotional intensity, reducing the “massive amplitude” of emotions.

Cognitive / academic performance

• Singing is said to be associated with improved academic outcomes and increased cognitive ability.
• The speaker emphasizes that singing and studying complement each other and involve different “sides of the brain”/brain systems.

Biochemistry and metabolism during singing

Melatonin production

• Singing or humming is claimed to increase melatonin, a hormone associated with relaxation and sleep.
• Additional subtitles claim melatonin (or singing-related effects) can reduce tumor growth, suggesting singing/humming may hinder tumor growth as supportive therapy (not a standalone treatment).

“Happy hormones” / neurotransmitters

• Singing is described as increasing dopamine, endorphins, and serotonin, associated with feeling better, happiness, reduced worry, and improved mood.

Stress hormone reduction

• Cortisol and adrenaline (“stress hormones”) are described as reduced when singing.
• Meanwhile, “good hormones” are described as rising, promoting relaxation and reducing being “over-alert.”

Oxytocin increase (“hug/cuddle/love hormone”)

• Singing together is claimed to strongly increase oxytocin, supporting bonding and social connection.
• The subtitle frames this as a mechanism behind why people in choirs often feel unusually connected after rehearsals (a shared team/family feeling).

Implied effects on brain and body (as stated)

• Improved social skills and peer connection
• Better emotional coping, especially during puberty
• Better cognition/academic ability
• Changes in hormones/neurochemicals:
  • ↑ melatonin (and a possible anti-tumor effect claim)
  • ↑ dopamine, endorphins, serotonin
  • ↓ cortisol, adrenaline
  • ↑ oxytocin (especially with group singing)
• Overall shifts toward calmness, joy, connectedness, and reduced stress
