How stress affects your body – Sharon Horesh Bergquist

Cramming for a test? Trying to get more done
than you have time to do? Stress is a feeling we all experience
when we are challenged or overwhelmed. But more than just an emotion, stress is a hardwired physical response
that travels throughout your entire body. In the short term,
stress can be advantageous, but when activated too often or too long, your primitive fight or flight
stress response not only changes your brain but also damages many of the other
organs and cells throughout your body. Your adrenal gland releases
the stress hormones cortisol, epinephrine,
also known as adrenaline, and norepinephrine. As these hormones
travel through your blood stream, they easily reach
your blood vessels and heart. Adrenaline causes
your heart to beat faster and raises your blood pressure,
over time causing hypertension. Cortisol can also cause the endothelium,
or inner lining of blood vessels, to not function normally. Scientists now know
that this is an early step in triggering the process
of atherosclerosis or cholesterol plaque
build up in your arteries. Together, these changes increase
your chances of a heart attack or stroke. When your brain senses stress, it activates your
autonomic nervous system. Through this network
of nerve connections, your big brain communicates
stress to your enteric, or intestinal nervous system. Besides causing butterflies
in your stomach, this brain-gut connection can disturb
the natural rhythmic contractions that move food through your gut, leading to irritable bowel syndrome, and can increase your
gut sensitivity to acid, making you more likely to feel heartburn. Via the gut’s nervous system, stress can also change the composition
and function of your gut bacteria, which may affect your digestive
and overall health. Speaking of digestion, does chronic
stress affect your waistline? Well, yes. Cortisol can increase your appetite. It tells your body to replenish
your energy stores with energy dense foods and carbs,
causing you to crave comfort foods. High levels of cortisol can also cause you
to put on those extra calories as visceral or deep belly fat. This type of fat doesn’t just make
it harder to button your pants. It is an organ
that actively releases hormones and immune system chemicals
called cytokines that can increase your risk
of developing chronic diseases, such as heart disease
and insulin resistance. Meanwhile, stress hormones
affect immune cells in a variety of ways. Initially, they help prepare
to fight invaders and heal after injury, but chronic stress can dampen function
of some immune cells, make you more susceptible to infections,
and slow the rate you heal. Want to live a long life? You may have to curb your chronic stress. That’s because it has even been
associated with shortened telomeres, the shoelace tip ends of chromosomes
that measure a cell’s age. Telomeres cap chromosomes to allow DNA to get copied
every time a cell divides without damaging
the cell’s genetic code, and they shorten with each cell division. When telomeres become too short,
a cell can no longer divide and it dies. As if all that weren’t enough, chronic stress has even more ways
it can sabotage your health, including acne, hair loss, sexual dysfunction, headaches, muscle tension, difficulty concentrating, fatigue, and irritability. So, what does all this mean for you? Your life will always be filled
with stressful situations. But what matters to your brain
and entire body is how you respond to that stress. If you can view those situations
as challenges you can control and master, rather than as threats
that are insurmountable, you will perform better in the short run
and stay healthy in the long run.

  20. For those with high stress and/or panic attacks: go two whole weeks without eating any processed foods and significantly lower your sugar intake. As someone with panic disorder I cannot recommend this enough. It doesn't CURE but it absolutely helps. Try it for two weeks, see how you feel, and decide whether you want to keep it up or not.

  22. I’ve been having a really tough year and a half. I really don’t know how I developed anxiety but that’s where it started, then it was some sort of depression and all of that was accompanied with stress. My stress levels where really really high, every muscle in my body twitches (literally every single one), headaches, I gained a lil weight cause I was craving sweet foods a lot, my colesterol went up a bit and I was in a non ending cycle of feeling ill, going to the doctor, running blood tests to see if everything was okay, not eating well cause my stomach hurt, more tests, etc. All I have is stress and it was killing me slowly, I even planned on taking my life cause I was fed up. Stress is horrible. I’m getting better slowly, the twitches are still there

  23. I'm currently stress daily and I constantly have cough and flu this past 2 weeks 😔 my stress and anxiety and depression seem to be chronic.
