5.2.1 study Flashcards
maintaining your health
define:
not getting the proper amount or quality of sleep.
sleep deprivation
define:
the body’s natural clock.
circadian rhythm
define:
bodily system that protects the body from substances that can make you ill.
immune system
which body system has these effects of sleep deprivation over time?
the body remains in a high state of alert, which causes more stress hormones to be produced, which then leads to rising blood pressure, which can then increase a person’s risk of heart attack, stroke, cancer, and diabetes.
cardiovascular system
which body system has these effects of sleep deprivation over time?
there is a decrease in a person’s ability to concentrate, think clearly, and solve problems. information is difficult to retain. it may also increase a person’s risk for mental illnesses such as bipolar disorder and depression.
nervous system
which body system has these effects of sleep deprivation over time?
blood sugar levels can spike, causing the body’s metabolism to slow. slow metabolism is linked to obesity and diabetes. lack of sleep may also be linked to poor digestive health and ailments such as irritable bowel syndrome and constipation.
digestive system
which body system has these effects of sleep deprivation over time?
the amount of cytokines decreases, making a person more susceptible to disease and infection.
immune system
define:
habits and behaviors promoting healthy amounts of sleep.
sleep hygiene
which body system do these negative effects apply to?
the body naturally tenses up as a defense mechanism when experiencing stress. continued tensing can lead to chronic neck and back pain.
musculoskeletal system
(muscles, joints, tendons.)
which body system do these negative effects apply to?
people who are stressed often breathe harder. it can cause hyperventilation.
respiratory system
(lungs, blood vessels).
which body system do these negative effects apply to?
intense stress can lead to increased heart rate. constant stress can increase a person’s risk of long-term heart problems.
cardiovascular system
(heart, blood vessels, arteries).
which body system do these negative effects apply to?
this body system initiates the body’s overall stress response. it signals the endocrine system to produce hormones elevating various body functions, such as heart and breathing rates. high stress levels over a long period can eventually wear down the body.
nervous system
(brain, spinal cord.)
which body system do these negative effects apply to?
this body system works to provide a boost of energy. cortisol and epinephrine signal the liver to produce more glucose, providing extra energy. if a person experiences constant bursts of energy, they can begin to feel depleted.
endocrine system
(liver, adrenal gland, adrenal medulla.)
which body system do these negative effects apply to?
people experiencing stress often change their eating habits. some begin to eat more, while others begin to eat less. diet changes can cause acid reflux and heartburn. some people experience nausea, stomach pain, or vomiting. stress also affects this body system’s ability to break down food. when food isn’t digested properly, it can lead to constipation or diarrhea.
digestive system
(esophagus, stomach, bowels.)
define:
chemical in the brain that helps a person feel happy.
endorphin
