What Coronavirus Stress Is Doing To Your Brain And Body

 Abby Tang: How are you feeling? Graham Flanagan: I played that song, ♪ You had a bad day ♪ Alex Appolonia: I wrote down some points because my brain is like mush lately. Fran Lam: Sad, worried, stressed. Victoria Barranco: Physically, like all of the negative emotions. Abby: This probably sounds super familiar, and that’s because a lot of us are feeling stressed right now. But this isn’t normal stress. This is pandemic stress, and it is messing with our brains in a particular way. When you get stressed, it triggers a chain reaction that starts in the amygdala, your emotional-processing headquarters. Your eyes and ears send info to the amygdala, and it determines if what you’re seeing and hearing is stressful. If it is, it sends a signal to your command center, the hypothalamus. It’s in charge of getting the word out to the rest of your body by way of the autonomic nervous system. The adrenal glands get the message first and pump adrenaline into your bloodstream. Your heart beats faster; you breathe more rapidly because your muscles need extra blood and your brain needs extra oxygen. They’re preparing to react to whatever threat is causing your stress response. All of this happens in the blink of an eye. It’s like how people can jump out of the way of a car without really thinking about it. The emotional amygdala overrides your prefrontal cortex, the part of your brain where all the logic happens. So you don’t get a chance to think things through; you just react. Once the threat dies down, though, the parasympathetic nervous system takes over and returns all those heightened reactions to normal. But if the brain still detects danger after the initial adrenaline rush, the hypothalamus sends out another message to the rest of the HPA axis. This triggers another series of hormones that lead to the release of cortisol, which signals to the body that it needs to stay on high alert and keep pumping out stress hormones. Right now for a lot of us, that threat is still very much alive. The amygdala is still overriding the prefrontal cortex, which is in charge of decision-making and planning. So those feelings of forgetfulness and tiredness, they’re likely a product of this stress response that won’t turn off. Stress hormones and the accompanying bodily responses are super helpful in the short term, but our bodies aren’t meant to function in this heightened state for weeks or months at a time. And over time, your brain will burn out. When it does, it can lead to allostatic load, the cumulative wear, and tear that happens to your body when you’re dealing with chronic stress. A high, prolonged cortisol level can mess with a lot of stuff. It’s even been seen to decrease the volume of your hippocampus, the area responsible for learning and memory, and a reduced hippocampus is more often seen in people with depression than those without. So all this is to say that the extra stress is probably not doing your brain or your body any favors. And humans are historically bad at making decisions when they don’t know what’s going to happen? So, what can you do to reduce the allostatic load? Reduce stress. Eating well, exercising, and maintaining a regular sleep schedule cannot be overlooked. Exercising alone can reduce stress hormones, even with just a 20-minute walk. And a different way of thinking could also help us: an idea called model-free learning. It’s trial and error. Instead of basing your risk assessment on similar examples from the past or envisioning future scenarios, you just take it one step at a time. This way, you reassess and update your estimate of what’s happening and how to prepare. We’re dealing with a new virus, constantly changing policies, and likely a completely different schedule and maybe even environment. Our brain is on high alert at all times to identify potential threats. This means that even if you’re spending most of your time laying around, your brain isn’t, so try not to beat yourself up for feeling tired or fuzzy, or unmotivated. You just don’t need anything else to stress about. Now that you know all of this, how are you feeling? Alex: To be honest, I do still feel the same. Fran: I think I’m feeling a bit better after watching it. Victoria: It’s my body is exhausted from feeling things and being under stress all day, all the time. Graham: Whenever I feel that allostatic load starting to weigh down on me, you know, I can put a name on it, a face on it, and it makes it a lot easier to deal with it.As found on YouTubeAnimationStudio ꆛ☣ꐕ Be The “Middle Man” And Profit With AnimationStudio Agency License.

He is training a holy remnant that will be solely dedicated to God and His work during these last days. God is raising up a people who are committed to him and his cause who are a holy remnant, and who are steadfast and sure of their God. Eli was judged soft on sin and allowed wickedness in the tabernacle at Shiloh; even his own sons. Today, the church world is a laughing stock because of wickedness in the house of God, there is no power or spiritual authority, no presence of the Lord in many churches. But there is an unseen remnant of people, who would surprise you, because they are not prominent, or well known, but they are shut in with and hearing a word from God. And the word is prepare, for judgment is coming.About David Wilkerson David Wilkerson was the Founding Pastor of Times Square Church in New York City. He was called to New York in 1958 to minister to gang members and drug addicts, as told in the best-selling book, The Cross and the Switchblade. In 1987, David Wilkerson returned to “the crossroads of the world” to establish Times Square Church. As a pastor of the church, he faithfully led this congregation, delivering powerful biblical messages that encourage righteous living and complete reliance on God. David Wilkerson had a strong burden to encourage and strengthen pastors throughout the world. From 1999 to 2008, he traveled around the globe holding conferences for Christian ministers.Posted with written permission of Time Square Church http://www.tscnyc.org/media_center.php?pg=sermons Copyright © 2016 Times Square Church, 1657 Broadway, New York, NY, 10019, USA.

Even today their sermons remain burned in my memory: “The Bible says Christ will come like a thief in the night, when you least expect him. It will happen in the twinkling of an eye, with the sound of a trumpet. You must be ready at all times.” The powerful cry, “Jesus is coming!” is seldom heard in God’s house today. Very few Christians live with a sense of expectancy, looking and yearning for Jesus’ return. How has this happened? The New Testament gives many warnings that mockers will appear in the last days, ridiculing the doctrine of Christ’s coming. Peter writes, “There shall come in the last days scoffers, walking after their own lusts, and saying, Where is the promise of his coming? For since the fathers fell asleep, all things continue as they were from the beginning of the creation” (2 Peter 3:3-4). This mocking can be heard today: “What does anyone have to fear? All things continue just as they always have. There is no reason to fear a Judgment Day, because it simply isn’t coming.”The devil has whispered a different lie into the ears of many believers. That lie is, “Christ has delayed his coming.” Jesus addresses this in Matthew 24 in his parable about being ready for his return: “Be ye also ready: for in such an hour as ye think not the Son of man cometh. Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? Blessed is that servant, whom his lord when he cometh shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. “But and if that evil servant shall say in his heart, My lord delayeth his coming; and shall begin to smite his fellow servants, and to eat and drink with the drunken; the lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, and shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth” (Matthew 24:45-51). Jesus is speaking here about believers, identifying them as servants. One of these servants is faithful while the other is evil. What makes the second servant evil in the Lord’s eyes? According to Jesus, it is something “he shall say in his heart” — that “the Lord delays his coming.” In other words, he’s convinced Jesus won’t come suddenly or unexpectedly. He has been instructed to “watch,” to “be ready,” “for the Son of man cometh at an hour when ye think not” (Luke 12:40). But instead this servant eases his conscience by believing Satan’s lie. Once he accepts the devil’s lie, here is the fruit: Because he sees no need to watch for Christ’s coming, he doesn’t see any need to make peace with his fellow servants. There is no need to preserve unity at home, at work, in the church, no need to make things right with others. Instead, he feels he could “smite his fellow servants,” accusing them, holding grudges and destroying others’ reputations. This servant seeks only to play, to have pleasure, to live with no conscience. In short, he wants both Jesus and the world. …© 2012 World Challenge. All rights reserved.

Within that short span, the whole world will witness fast-falling destruction upon a city and a nation, and the world will never be the same.If you are attached to material things — if you love this world and the things of it — you won’t want to hear what Isaiah has prophesied. In fact, even to the most righteous of God’s people, what Isaiah says might seem unthinkable. Many would surely ask, “How can an entire world be stricken in one hour?”If we didn’t believe the Bible is God’s pure Word, few of us would take Isaiah’s prophecy seriously. But Scripture makes it clear: in a single hour, the world is going to change. The church is going to change. And every individual on earth is going to change.The apostle John gives a similar warning in Revelation. He speaks of destructive judgment coming upon a city and nation: “In one day, death, and mourning, and famine; and she shall be utterly burned with fire: for strong is the Lord God who judgeth her…. For in one hour so great riches is come to nought” (Revelation 18:8, 17).……………….According to this prophecy, sudden judgment is coming upon the earth, and it will change everything in a single hour.

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.
