This Breathing Exercise is Better Than Normal Exercise

People suffering from low blood pressure may soon have an easier time exercising to keep their pressure at the proper level thanks to a handheld device. Researchers have found a technique that is more efficient than traditional exercise. Patients can keep their blood level at a safe level by practicing a breathing technique known as High-Resistance Inspiratory Muscle Strength Training (IMST). Basically the exercise helps strengthen the of the diaphragm by providing some resistance. Of course, there are still many benefits to just going for a walk.

Results show participants in the IMST group saw their systolic blood pressure fall by an average of nine points. That kind of improvement, researchers say, is generally better than what high blood pressure patients see from walking 30 minutes a day five days a week. The study finds the IMST results are even on par with certain blood pressure-lowering drugs prescribed to patients.

Perhaps more importantly, study authors find people doing IMST saw their blood pressure continue to stay low even after they stopped the breathing workouts for six weeks. â€œWe found not only is it more time-efficient than traditional exercise programs, the benefits may be longer lasting,â€ says Craighead.

Home Water Heaters can Reduce Electricity Production

Across North America homes have massive tanks of hot water regardless of the outside temperature or other concerns. The energy cost to heat all this water is immense and not only can we reduce this cost we can use the water itself to power homes. The basic idea is to convert the temperature change in water into energy and vice versa to have the water tanks function has batteries. The coolest thing about this idea is that it’s not even a new one.

Here’s how it works. The heat pump water heater is like a refrigerator running in reverse. Instead of taking heat out of the unit (cooling) and dumping it into the nearby room air, the heat pump water heater dumps heat from the air around it into the water. This is vastly more efficient than heating water in the old way, with a high-wattage electric coil.

There is actually aÂ little-known tradition, going back to the late 1930s, of electric companies managing water heaters to avoid short-squeezes on the grid during times of peak consumption. Because water can be kept hot so long, consumers don’t even notice. Originally this was done with timers, later via radio signals, and today through the cloud. And, thanks to smart meters that track energy use by the minute, demand-shifts can be very precisely targeted and valued. Water heaters, reborn asÂ big thermal batteries, are an excellent means by which lots of clean power can be strategically banked for later use.Â Hundreds of thousandsÂ of water heaters haveÂ alreadyÂ been quietly hooked up this way. This is just theÂ tipÂ of the potential iceberg.

Explaining Degrowth and Why it Matters

The way the economy runs leads to environmental destruction and it doesn’t have to be that way. The industrial revolution accelerated consumption of non-renewable resources and governments allowed corporations to profit at the expense of health and wellbeing. This is untenable. It’s time to shift our economy from one that exists to expand every year (so billionaires like Musk and Bezos) to one that exists for long-term sustainability. Without the environment we won’t even have an economy, and with climate change accelerating we have to refocus our economy immediately.

Degrowth, at its essence, is an alternative to capitalism, Parrique says. But what it absolutely is not, he says, is a planned recession on purpose. Not only does pausing economies for a moment do pretty little for the climate crisis (look how ineffective COVID-19 was at reducing emissions long-term), but it also hits the poorest and most vulnerable people first.

Parrique says to picture economies like people with metabolismsâ€”when youâ€™re young, you need to eat lots of food, and as a result, produce lots of waste, to get big and strong. But if you keep eating like a rapidly-growing human well into adulthood, thatâ€™s probably not the healthiest way to be. As an adult, it makes more sense to balance out your diet for sustaining your bodyâ€™s current needs.

Cleaner Air Produced $5 Billion in Crops

Farmers can’t control the air quality of their farms, yet the air makes quite the difference to the success of the crops. Since air can’t respect property rights it requires governments to act, and that’s what happened back in the 1990s in the USA when environmental regulations to improve air quality were put in place. A study of the impact of those regulations revealed that $5 billion USD in crops can be traced back to improved air quality.

Protecting the environment is good for the planet and for profits!

Focusing on a nine-state region (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, South Dakota and Wisconsin) that produces roughly two-thirds of national maize and soybean output, Lobell and study co-author Jennifer Burney, an associate professor of environmental science at the University of California, San Diego, set out to measure the impact on crop yields of ozone, particulate matter, nitrogen dioxide and sulfur dioxide.

“This has been a tricky problem to untangle because historically our measurements of different types of air pollutants and our measurements of agricultural yields havenâ€™t really overlapped spatially at the necessary resolution,â€ explained Burney. â€œWith the new high spatial resolution data, we could look at crop yields near both pollution monitors and known pollutant emissions sources. That revealed evidence of different magnitudes of negative impacts caused by different pollutants.â€

How Dar Jacir Supports Artists in Exposing Colonialism

In Bethlehem a group of artists founded an organization, Dar Jacir, which set out to support artists in Palestine and beyond. Dar Jacir is a an art and research centre that’s currently grabbling with the fallout of the latest bombings by Israel in the last few months. Despite the damage done, the organization is still set on supporting artists express themselves and their frustrations in a creative way. No matter how much conflict there is, artists will find a way!

What Dar Jacir is doing is incredibly important. Itâ€™s so hard to have a space like this, especially in Bethlehem, where itâ€™s right next to the Israeli wall. Itâ€™s trying to create something in a place you know is going to be bombarded over and over again. Conceptually, itâ€™s an act of resistance â€“ now, more than ever, when Bethlehem finds itself completely isolated because of the wall and the increasing settlements around the city. Itâ€™s very difficult to go to Ramallah, which used to be a 40 minutesâ€™ drive. Now, it takes two hours â€“ sometimes more, with all the checkpoints.

The nice thing about art institutions is that theyâ€™re a bit subversive in that sense. They can host artists from other places, even places that the country is officially at war with. It helps make a link between what is going on in Lebanon and Syria and Palestine. Itâ€™s something that is very important for our unity and for resisting the colonial structures that weâ€™re fighting against.
