  • Laughter is the best medicine!
    • Laughter improves resistance to disease by:
      • Decreasing stress hormones
      • Increasing immune cells and infection-fighting antibodies
      • Even just anticipating a funny effect can positively affect your immune system!

 

  • The immune system is strengthened only one month after quitting smoking
    • Immune cell activity increases
    • Levels of the stress hormone cortisol decreases
      • Higher and more prolonged levels of cortisol in the bloodstream (like those associated with chronic stress) have been shown to have negative effects, such as:
        • Impaired cognitive performance
        • Suppressed thyroid function
        • Blood sugar imbalances such as hyperglycemia
        • Decreased bone density
        • Decrease in muscle tissue
        • Higher blood pressure
        • Lowered immunity and inflammatory responses in the body, slowed wound healing, and other health consequences

 

  • Dieting weakens the immune system
    • Restriction in food intake causes deficiency in necessary vitamins and nutrients for optimal protection of the immune system

 

  • Lack of sleep (under 5 hours) is linked to weaker immune systems
    • Sleep deprivations causes quantity of T-cells to decrease, which consequently decreases body’s ability to respond to infections

 

  • Antibacterial products may actually weaken the immune system
    • The frequent hand washing can break down the natural oils on the skin that serve as the first line of defense for the immune system

 

  • Intense endurance exercise disrupts immune system functions
    • Intense endurance exercise is characterized by any activity performed at 85% percent of maximum effort for at least 30 minutes
    • Such exercise intensity destroys some white blood cells and triggers whole body inflammation for up to 72 hours
