Key Points

  • ADHD is influenced by a combination of genetic and environmental factors, with studies showing that genetics account for approximately seventy-five percent of the condition's prevalence.
  • Laughter yoga, which combines breathing exercises, mild physical workouts, and spontaneous laughter, has been shown to positively impact cardiovascular health and enhance mood and well-being.
  • A recent Swedish study suggests that consuming high-fat dairy products like cream and cheese may be linked to a lower risk of dementia, although further research is needed to confirm these findings.
