What’s normal anxiety — and what’s an anxiety disorder? | Body Stuff with Dr. Jen Gunter | TED

Transcriber We live in a culture that doesn’t take mental health issues seriously. There’s a lot of stigma.Some people tell you to just suck it up or get it together or to stop worrying or that it’s all in your head.But I’m here to tell you that anxiety disorders, they’re as real as diabetes, Music Body Stuff with Dr Jen Gunter Hi.Again It’s, Dr Jen, and I’ve noticed something with my patients.They often describe to me some classic symptoms of an anxiety disorder.Constant worry, trouble, sleeping tense muscles, and struggle with concentrating, But they aren’t getting treatment.There are a lot of issues with mental health care in this country.Some people, don’t have insurance that would cover it.Some have been dismissed or minimized in the past and don’t think seeking help will do any good.Some worry about the stigma and whether it could affect future jobs or relationships But severe anxiety. Isn’t a moral or personal failing It,’s a health problem, just like strep throat or diabetes.It needs to be treated with the same kind of seriousness.Before we can talk about anxiety disorders, let’s talk about anxiety itself.Anxiety is the very real and normal emotion we feel in a stressful situation.It’s related to fear, But, while fear is a response to an immediate threat that quickly subsides anxiety is a response to more uncertain threats that tend to last much longer.It’s all part of the threat detection system that all animals have to some degree to help protect us from predators.Anxiety starts in the brain’s amygdala a pair of almond-sized nerve, bundles that alert other areas of the brain to be ready for defensive action.Next, the hypothalamus relays the signal setting off what we call the stress response in our body, Our muscles tense, our breathing and heart rate increase and our blood pressure rises.Areas in the brain stem kick in and put you in a state of high alertness.This is the fight-or-flight response. There are ways the fight or flight response is kept somewhat in check with an area of higher-level thinking called the ventromedial prefrontal cortex.It works like this.If a person sees something they think is dangerous, like a tiger that sends a signal to the amygdala saying it’s, time to run The ventromedial prefrontal cortex can say to the amygdala: Hey, look The tiger’s in a cage.You know what a cage is.They can’t escape from a cage.It’s, OK, to calm down It’s, a feedback loop that can help keep the response in check.The hippocampus is also involved.It provides context by saying things like Hey: we’ve seen tigers in cages before We’re in a zoo.You are extra safe With anxiety.These threat detection systems and mechanisms that reduce or inhibit them are functioning incorrectly and cause us to worry about the future and our safety in it. But for many people, it goes into overdrive.They experience persistent pervasive anxiety that disrupts work, school, and relationships and leads them to avoid situations that may trigger symptoms.Anxiety disorders are not at all uncommon, Based on data from the World Mental Health Survey.Researchers estimate that about 16 percent of individuals currently have or have had an anxiety disorder.These include social anxiety, disorder, panic, disorder, agoraphobia and phobias.Studies have shown that people with anxiety disorders, don’t just have a different way of reacting to stress.There may be actual differences in how their brain is working.One model describes a possible mix.Ups in the connections between the amygdala and other parts of the brain, The pathways that signal anxiety become stronger And the more anxiety you have, the stronger the pathways become and it becomes a vicious cycle.The good news is there’s, treatment for anxiety and that you, don’t have to suffer. Remember this isn’t about weakness.It’s about changing brain patterns and research shows that our brains can reorganize and form new connections.Throughout our lives, A good first step is to do the basics, Eat a balanced diet, exercise regularly, and get plenty of sleep.As your mind is part of your body.It might also help to try meditation Instead of our heart rate, rising and our body tensing with mindfulness and breathing.We can slow down the fight or flight response and improve how we feel in the moment through cognitive behavioral therapy.A form of talk therapy can also be fantastic In it.You learn to identify upsetting thoughts and determine whether they’re realistic Over time.Cognitive behavioral therapy can rebuild those neural pathways that tamp down the anxiety response.Medication can also give relief in both the short term and the long term. In the short term, anti-anxiety drugs can down-regulate the threat, and detection mechanisms that are going into overdrive.Studies have shown that both long-term medications and cognitive behavioral therapy can reduce the overreactivity of the amygdala.We see anxiety disorders, High blood pressure, and diabetes.They can be treated or managed over time, And the same is true for an anxiety disorder too.

10 Amazing Photos Of The Human Body Under A Microscope

Some of these photos are artistic, others are terrifying.

Colin Salter’s new book, Science is Beautiful (Batsford, 2015), shows us some amazing images of the human body under a microscope. When the photos are colorized they look like masterpieces of art. Check them out below:

1. This is what bone marrow making blood looks like.

Science Photo Library / Via Batsford

Stem cells in bone marrow divide and transform into blood cells. This process is constantly happening because blood cells don’t live for a very long time: “Red ones about 120 days, some white ones as little as three,” writes science writer Colin Salter in his book Science is Beautiful.

2. And these are our lung cells.

Science Photo Library / Via Batsford

“Nuclei, which contain the cell’s genetic information, appear blue. Mitochondria, which generate energy for the cell, are yellow,” writes Salter.

3. These are adrenaline crystals.

Science Photo Library / Via Batsford

“[Glands that produce adrenaline] are controlled by the hypothalamus, the part of the brain responsible for instinct and emotion,” writes Salter. We always have small amounts of adrenaline in our blood, but when we’re stressed we get more.

“It widens the airways of the lungs and constricts small blood vessels. This makes the muscles work harder and produces a ‘fight or flight’ response,” he wrote.

4. And these crystals are serotonin.

Science Photo Library / Via Batsford

Ninety percent of the serotonin in our body is found in our gut (yes our digestive system, this includes our bowels). Seratonin is often called the “happy hormone”, though it’s a lot more complicated than that. It also plays a part in memory, learning, mood, appetite and sleep.

5. This is a balancing stone from our inner ear.

Science Photo Library / Via Batsford

There’s a tiny stone in each of our ears that’s responsible for our sense of balance. The stones are attached to sensory hairs that are sensitive to gravity and acceleration. When we tilt our head the hairs send nerve impulses to our brain so that we can stay balanced.

6. These are insulin crystals.

Science Photo Library / Via Batsford

“Insulin is produced in the pancreas, and its function is to regulate blood sugar levels,” Salter wrote. If not enough insulin is produced then your blood will accumulate too much glucose which can lead to diabetes. Even if your body produces insulin correctly you can still get diabetes if your cells don’t respond to it.

7. This is what human skin really looks like up close.

Science Photo Library / Via Batsford

“The outer layer of the skin, the epidermis (top half of this image) consists of dead cells that are constantly sloughed off and replaced from below,” he wrote. The yellow things are a protein called keratin which makes the skin waterproof and strong, so that your organs inside don’t get damaged. The black things are hair follicles.

8. This is what melatonin looks like.

Science Public Library / Via Batsford

When it gets dark, your eyes send messages to a gland that produces melatonin – a hormone linked to sleep. “In middle age, melatonin secretion drops off. This may be responsible for aging symptoms such as insomnia and irritability,” he wrote.

9. These are fat cells that have been emptied.

Science Public Library / Via Batsford

Fat cells are some of the largest cells in the human body. The thick layer of fat under our skin cushions us and stores energy. In this picture, the fat deposits of the cells have been removed.

“When we put on weight, the cells swell with additional fat, and eventually extra cells are added too,” he wrote.

10. This is a a bacteriophage.

Science Public Library / Via Batsford

“Bacteriophages are viruses that infect bacteria,” he wrote. The orange spider-looking thing is a bacteriophage that has just injected its viral DNA into an E. coli bacterium (the blue image).

The “legs” are syringe-like tubes that puncture the cell membrane in order to empty its DNA contents into the bacterium.

“New phages then grow, kill and depart from the host cell within 30 minutes,” he wrote.
