The traditional definition of burnout

Burnout can be defined as a combination of exhaustion, cynicism, and inefficiency. People who feel burned out may experience a lack of emotional energy to attend to their work, withdraw from colleagues and customers, and may feel incompetent as a result.

But not everyone experiences burnout in the same way. A better framework can help to understand the many subtypes of burnout.

The three types of burnout

nesslabs.com

  • The frenetic worker. Despite feeling overloaded and overwhelmed with work, you work increasingly harder, ignoring your own needs to the point of exhaustion.
  • The under-challenged worker. You have to cope with monotonous conditions that fail to provide satisfaction. You feel that your work lacks opportunities to develop your abilities.
  • The worn-out worker. You are mentally, physically, and emotionally exhausted. You become passive and unmotivated.

Researchers listed fifteen different coping strategies commonly used by people experiencing burnout. Not all coping mechanisms are constructive.

  1. Social support
  2. Humour
  3. Better planning of workload
  4. Restraint
  5. Focus on solving the problem
  6. Personal growth
  7. Positive reinterpreting of your challenges
  8. Distracting activities
  9. Religion
  10. Acceptance
  11. Substance abuse
  12. Behavioural disengagement
  13. Venting of emotions
  14. Denying the situation
  15. Cognitive avoidance

Regardless of the coping strategies you use, try not to push through burnout. Attempt to get support, take a break, and make space for self-reflection.

Ultrasound for clinical purposes: The history
  • Ultrasound was first used for clinical purposes in 1956 in Glasgow.
  • Obstetrician Ian Donald and engineer Tom Brown developed the first prototype systems based on an instrument used to detect industrial flaws in ships.
  • They perfected its clinical use, and by the end of the 1950s, ultrasound was routinely used in Glasgow hospitals..
  • It really took off in British hospitals in the 1970s, and it was well into the 1970s before it became widely used in American hospitals.
  • By the end of the 20th century, ultrasound imaging had become routine in maternity clinics throughout the developed world.

The History of Ultrasound

livescience.com

  • Ultrasound imaging involves bouncing "ultrasonic" sound waves at body structures or tissues, and detecting the echoes that bounce back.
  • Obstetric ultrasonography is used to image a human fetus inside its mother's womb.
  • Based on the angle of the beam, and the time it takes for echoes to return, an image of body structures inside the fetus can be generated.
  • It's used to confirm a pregnancy, to identify the sex and number of fetuses and to detect fetal abnormalities such as microcephaly, absence of kidneys, and spinal problems.
Ageing well

How people age has everything to do with the life choices they make now - what they eat and how they view the world.

One of the simplest ways to age well is to understand that what you put into your body and mind will affect every part of your body.

I'm A Functional Medicine Doctor & Here's How You Can Nurture Your "Longevity Genes"

mindbodygreen.com

Warning signs from your body that it is underperforming: you're achy, tired, gaining weight, and not sleeping well.

However, the right choices can radically change and even reverse some of the symptoms. Studies show that it's never too late to start new habits and experience improvements.

Researchers state that there are about 20 longevity genes with the potential to help us live longer and healthier lives. The pathways of many of these genes respond to lifestyle habits such as what, when, and how much you eat, how you move your body, how much good sleep you get, and how much stress you endure.

Recent research suggests that we should eat more protein from plants and less from animals as we age. Younger people who are still growing need more meat and dairy.

Ultraviolet light is a type of electromagnetic radiation

UV light comes from the sun and is transmitted in waves or particles at different wavelengths an frequencies.

It makes black-light posters glow, and is responsible for summer tans. But too much exposure to UV radiation damage living tissue.

What Is Ultraviolet Light? | Live Science

livescience.com

EM is the broad range of wavelengths. It is divided into seven regions and ordered in decreasing wavelength and increasing energy and frequency, namely radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays.

Ultraviolet light falls is the range of the EM spectrum between visible light and X-rays.

  • UVA, or near UV (315-400 nanometers)
  • UVB, or middle UV (280-315 nanometers)
  • UVC, or far UV (180-280 nanometers)

Radiations with wavelengths from 10nm to 180nm are sometimes referred to as vacuum or extreme UV.

UV radiation has enough energy to break chemical bonds. UV photons can cause ionization, meaning chemical bonds will break that otherwise would not.

It can be useful, for instance, in disinfecting a surface, but it can also damage materials and living tissues, particularly the skin and eyes that are affected by UVB and UVC radiation.

Most natural UV light comes from the sun. Only 10 % of sunlight is UV, and only one-third of it gets through the atmosphere.

Of the solar UV energy that reaches the equator, 95% is UVA, and 5% is UVB. No measurable UVC from the sun gets to the Earth's surface, because ozone, molecular oxygen, and water vapour in the upper atmosphere absorb the shortest UV wavelengths.

A suntan is a reaction to exposure to UVB rays. When the body senses sun damage, it sends melanin, a pigment in the body, to absorb UV light and protect the body from more damage, resulting in a darkened skin.

Continued exposure to UV radiation can damage the body's DNA. When the body senses this destruction, it floods the area with blood and inflammation to help with the healing process. Sometimes the cells with DNA mutated by the sun's rays turn into problem cells, known as skin cancer.

Substances like minerals, plants, fungi, microbes, and organic and inorganic chemicals, can absorb UV radiation, causing electrons to jump to a higher energy level. When the electrons return to a lower energy level, they emit a portion of the absorbed energy as visible light.

  • Fluorescence is used for signs, safety vests, and other applications in which high visibility is important.
  • In fluorescent tubes, an electric current is passed through mercury vapour, producing ultraviolet radiation along with a blue light.

There are also other celestial sources of UV radiation.

Very large young stars shine most of their light in ultraviolet wavelengths. But the Earth's atmosphere blocks much of the UV radiation, and observations are conducted using high-altitude balloons and special orbiting telescopes equipped to observe the UV region of the EM spectrum.

Some skin conditions can be treated using UV light.

PUVA (psoralen ultraviolet light treatment) is used to treat lymphoma, eczema, psoriasis, and vitiligo. Patients take a drug or apply a lotion to make their skin sensitive to light. Then a UV light is shone on the skin, slowing down the growth of the skin cells.

A good night's sleep

A good night's sleep is essential for our overall good health. Memories are cemented during sleep, and students are often reminded that they need to have good sleep habits to maximize their learning.

New research shows that sleep is also vital for unlearning things (especially the things that we no longer need to fear). These findings may prove useful in helping those with or at risk of developing anxiety or post-traumatic stress disorder.

Some sleep is worse than no sleep for keeping fear in check

bigthink.com

  • New research shows that that people without sleep fare better in learning what to fear and not fear than those getting only some sleep.
  • Test subjects learned to associate colors with electric shocks, but only some unlearned it.
  • The findings could be used to help create new treatments for those at risk of PTSD or anxiety.
White noise

White noise is the sound of all the frequencies that humans can hear and is at the same intensity, such as a fan or crashing waves.

Around the globe, millions of people are downloading white noise apps in the hope of getting better sleep at night. However, research suggests that they don't work and that they even may make things worse.

White noise as sleep aid may do more harm than good, say scientists

theguardian.com

One theory is that white noise helps to drown out other bothersome sounds. Another is that listening to the same sound each night may help people to associate it with falling asleep.

Studies show that although there is evidence that people fall asleep sooner, the quality of the evidence was poor. There is also a concern of potential ill-effects of not allowing the auditory system to switch off overnight, although this has not yet been tested.

Macronutrient Dieting

If It Fits Your Macros (IIFYM) is a new diet that counts the daily macronutrients in the food and drinks we intake, mainly the fats, carbs and proteins. It provides flexibility and choice in our diet with the same results as a much stricter diet.

This popular new diet currently has no scientific research to test its effectiveness as compared to the previous diet plans of low-carb or low-fat consumption.

Calories or macros: nutritionist explains which works best for weight loss or building muscle

theconversation.com

Calorie counting does not take into account the type of nutrients consumed, reducing the many types of food into numbers. It essentially makes no distinction between cottage cheese and a chocolate bar, apart from the number of calories they have.

The advantage of counting the macros (fats, proteins and carbs) is that many essential nutrients (vitamins, minerals) are naturally incorporated in our food intake.

How much humans can eat

One study asked healthy participants to eat pizza until they felt full. Then on a separate day to eat pizza until they couldn't anymore. They ate twice as much as on the first take, suggesting that when you feel full, you're probably only half full.

Blood samples were also taken at regular intervals to see how the body was coping. Despite eating twice as much food, there was only a small increase in blood sugar and blood fat levels.

Here's how the body reacts to one-off overeating – new research

theconversation.com

  • Studies revealed that in physically active and healthy people, the body is able to control the sugar and fat in the blood after a big meal by working a bit harder than usual to regulate metabolism.
  • Hormones released from the gut and pancreas help the body to regulate blood sugar levels.
  • After participants ate past the point of feeling comfortably full, they had little desire to eat anything even four hours after the meal.
  • The also felt sleepier and less energetic after eating too much.

Healthy humans rely on the body's ability to work harder in times of need.

However, when we repeatedly eat too many calories at each meal, metabolic syndrome - a combination of high blood pressure, diabetes, and obesity - will result. Over time, the body will become unable to react to these situations.

Stress causes health problems

We’re all under stress right now. And the stress-reactive circuits in our brain guide us to respond ineffectively to stress and cause chronic stress and rising rates of emotional, behavioral, social, and physical health problems.

Train your brain to stop stress

inverse.com

  • The neural circuits in our emotional brain - the limbic system and subconscious memory systems - control our emotional responses in daily life.
  • When a stimulus arrives in the brain, it activates either stress-resilient circuits, the internal calmers and healers, or stress-reactive circuits.
  • The brain activates the strongest circuit, which controls our responses.
  • If the strongest circuit is the reactive circuit, our strong emotions get the upper hand, and the stress interferes with the part of our brain responsible for higher-level thinking and planning.
  • The longer the stress-reactive circuit is activated, the more likely they are to activate other stress-reactive wires, which can cause an emotional meltdown of anxiety, numbness, depression, and hostility.

The brain learns to be resilient by being resilient. It takes becoming stressed, then use emotional techniques to change the unreasonable expectations stored in that circuit.

  • One technique is to complain briefly. It activates the reactive wire that has encoded an incorrect response.
  • Then rapidly express emotions, starting with a burst of anger (which decreases stress). You can then stay present to your strong, negative emotions. Talk to yourself through finishing phrases like " I feel afraid that..." or "I feel sad that..."
  • Stress as a social response: We can spread stress to others that can eventually become large-scale group emotions.
  • Treating stress: The current model of treating stress symptoms with medications and procedures will require detox.

A long-term solution is to train the emotional brain for stress resiliency.

The internal clock

All individuals possess what is called 'an internal clock', which has as main purpose to schedule sleep and wakefulness within one entire day of 24 hours.

Now comes the difference in regards to how the 'clock' works for each person: there are people who wake up earlier and go to bed earlier as well - for them the cycle is shorter and there are also people who, on the other hand wake up later and go to sleep later. It all depends, in fact, on what is known as 'zeitgebers', which translates by external signals necessary in order to synchronize the 'clock'.

Is Your Sleep Out of Whack Now That You Are in Quarantine?

psychologytoday.com

Whenever we undergo a change in our daily schedule, our sleep tends to suffer a bit.

Simple facts such as not waking up and going to bed at the usual hour, not getting enough natural light or making less to no exercise can lead to sleep disorders.

Especially during times of staying only in the house, one needs to make sure that the regular schedule is not too much disturbed, as this can lead, among other issues, to sleep disorders.

A good way to get your normal sleep is by maintaining a regular wake-up and bedtime, even through unusual periods of time. Furthermore, ensuring that your room gets enough natural light, or even better, that you get it, will definitely help. Among other helpful tips there are the fact of giving up on coffee or making as many indoor physical exercises as possible.

There are times, in our life, when we have sleep difficulties for one reason or another.

In order to 'repair' your sleeping disorder, you might want to try whether waking up 15 minutes earlier every couple of days or, on the contrary, going to bed later by two to three hours. However, remember that the most important is to respect and, if possible, give priority to your body preferences. Of course, provided that your working schedule will not be affected.
