• Respiration influences many of the processes in our body that have a direct impact on our physical and mental health. 
• Each day, we take around 20,000 breaths.
• With every inhalation, our heart rate speeds up, and with every exhalation, it slows down. 
• The nervous system is especially sensitive to changes in breathing rate. 
• Through our breath, we can change our state from stress to relaxation, or from feeling dull to being energized. Longer-term, through being more attentive to the way we breathe, we can benefit our health and longevity. 

Scientists have been carrying out experiments and tests on the brain to understand its many functions and also to manipulate brain activity. New, increasingly detailed maps of the brain are now being drawn out.

Breakthroughs in technology let us change the brain’s structure, or plug it to external components, like a paralysed man controlling a robotic arm by simply commanding the brain.

Many people live like shift workers to some degree. The majority of people either go to bed after midnight or wake up early without getting enough sleep.

Shift work is a probable carcinogen, according to the WHO. Moreover, there is a list of health problems associated with shift work. The reason is that shift work interferes with your circadian rhythm. Humans are diurnal - we are designed to be awake in the day and asleep at night. While we can be nocturnal, we weren't built for it long term.

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.

• 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.

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.

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.

• 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 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.

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.
