Technician Christopher Olk concentrates hard as he removes the broken drive from a DVD player and pushes it back in again.
"If it's the mechanics or the electronics, I can fix it," explains the 26-year-old, who is working on his Ph.D. in battery technology at Aachen University. "If the chip or the cooling system is affected then I can't do anything, because I'm missing the equipment and spare parts."
In a small room inside a repair cafe in Cologne's civic center, Olk is one of four technicians who, with the help of some spanners and a soldering iron, try to breathe new life into faulty electronic devices, whether it's a razor, a toaster, a screen or a lamp.
Europe is full of broken-down equipment. With more than 12 million tons per year — the equivalent of 30,000 jumbo jets — Europe ranks second only behind Asia in terms of e-waste, according to the Platform for Accelerating the Circular Economy (PACE).
Manufacturers to Make Changes
"We want to avoid electronic waste and try to motivate people to act in an environmentally conscious way," says Dunja Karabaic, one of the repair cafe's founders.
The European Commission now wants to implement a new ecodesign directive at the EU level to help ensure home appliances have a longer functional lifespan — and it's banking on regulation.
At the repair cafe in Cologne, Christopher Olk is trying to get this faulty DVD player up and running again.
As of 2021, manufacturers across Europe will be required to improve both the reparability and service life of devices such as washing machines, refrigerators, dishwashers, electric motors, light sources and LED screens. Manufacturers must also be more precise when it comes to including energy consumption information on the labels of their products and providing replacement parts for at least 10 years after purchase.
Laptops and smartphones, however, are not covered under the new rules — more on that later.
Ecological Potential and the Right to Repair
The European Commission estimates that up to 167 terawatt hours of energy could be saved annually by 2030 — approximately the same annual energy consumption as Denmark, which has a population of 5.8 million. This could be achieved, on the one hand, through more energy efficient devices, and, on the other, as a result of fewer devices needing to be re-produced if they last longer in the first place.
When it comes to electricity and acquisition prices, the European Commission projects that EU citizens would save around €150 ($167) per year in the future.
Old televisions are much easier to repair compared to modern LED screens.
"Whether it is by fostering reparability or improving water consumption, intelligent ecodesign makes us use our resources more efficiently, bringing clear economic and environmental benefits," the European Commission Vice President for Jobs, Growth, Investment and Competitiveness, Jyrki Katainen, said in an official statement.
Environmental organizations have also welcomed the new regulations.
"From the U.S. to Europe, people are demanding their right to repair things they own because they're tired of products that are designed to break prematurely," said Chloe Fayole, the program and strategy director at the environmental organization ECOS. "Enabling consumers to repair and reuse all electronic products is just common sense."
How Long Should Devices Last?
Exactly how much longer electronic devices should last in the future is still unclear, as is a more detailed benefit analysis of the plan. But if the devices are easier to repair, "the turnover of product inventories will automatically decrease," Pierre Schweitzer, an expert on ecodesign at the European Environment Bureau (EEB) told DW. "That means that less electronic waste will be produced. But no one has tested the model yet, as to whether this will happen in practice."
The EEB has therefore submitted a report looking at the effects of measures which prolong the life of electronic devices. The calculations show that if washing machines in Europe were to function for just one extra year, it would have the same positive effect on the environment as if 133,000 cars were taken off the road.
On average, a washing machine currently lasts around 11 years. But according to the experts, it would have to be used for at least 20 years before the purchase of a new washing machine is advisable from an environmental point of view.
"That's how long it takes resources to use an old device — and to repair it," explains Rasmus Priess, a product sustainability expert from the Öko-Institut in Freiburg.
But not all electronic devices are created equal. If the energy footprint required to manufacture and then run a device is taken into account, a laptop should be used for 44 years, and a smartphone for up to 232 years. As mentioned earlier, these devices – along with small appliances like razors, blenders and toasters – won't be included in the new EU rules. The plan is to incorporate them at a later stage.
The DVD player, which Christopher Olk is busy fixing in the repair café in Cologne, hasn't made it onto the European Commission's list yet either.
Brussels will soon be discussing whether to include longer-lasting smartphones and laptops in the new regulations.
Gaps in the Rules
It took Olk 30 minutes to remove the device's case and take a look inside. After some tinkering, he still only managed open it by force. "See that old radio over there," he said, pointing to an antique mustard yellow transistor radio that has probably been around for several decades, "Underneath is a guide on how to open it and remove some of the parts. Something like that alone would help."
The German Federal Ministry for Economic Affairs and Technology (BMWI) has also been negotiating in Brussels. In a statement provided to DW, it says it is committed to ensuring that customers can make simple repairs themselves, while more difficult or dangerous repairs should be done by a specialist.
The cost of replacement parts may also limit the overall success of the new regulations: The scheme doesn't include a price break for spare parts.
Jean-Pierre Schweitzer from the EEB believes this has increased the risk of "an economic incentive to make spare parts either very expensive, or to manufacture products that break down regularly."
The more complicated the technology, the harder it is to identify which parts are broken.
An analysis by the Joint Research Center of the European Commission found that the main reason people didn't have a washing machine or dishwasher repaired was because "it was too expensive."
Paolo Falcioni, the Director General of APPLiA, an association representing home appliance manufacturers in Europe, has nevertheless praised the regulations as "a balanced representation of interests." But he also sees some disadvantages. On the one hand, APPLiA fears that the regulations would mean fewer devices would be approved for the European market. On the other hand, it also wants to avoid any unfair competition.
'Repairing Is More Important Than Recycling'
But although there is still room for improvement, Jean Pierre Schweizer from EEB says the new legislation is "groundbreaking" because it acknowledges the importance of using devices as long as possible.
"When we talk about a circular economy, repairing is a very efficient point at which you can save real resources and emissions — and that's just the start. We really should highlight the positive aspects of this legislation."
Not all electronic devices can be repaired using normal, everyday tools.
Back at the repair cafe, Christopher Olk has given up. The DVD player is beyond saving. This isn't an unusual outcome here.
Braco Sladakovic, who brought in his defective LED TV, has also admitted defeat. The backlight no longer works.
"We tried, but it was too complicated," he told DW. "It's not worth it anymore, unfortunately." The spare part needed is cheap enough to replace, but the repair itself would be too difficult and expensive.
Sladakovic now needs to decide what to do with his broken TV. He might be able to sell if to a hobbyist for a few euros. Or he'll simply take it to the nearest electronic waste dump.

Whether you've hit a workout plateau or you're just ready to turn things up a notch, adding more strenuous exercise — also known as high-intensity exercise — to your overall fitness routine is one way to increase your calorie burn, improve your heart health, and boost your metabolism.
However, to do it safely and effectively, there are some guidelines you should follow. Keep reading to learn more about the benefits of vigorous exercise and how to safely dial up the intensity of your workouts.
What Is Considered Strenuous Exercise?<p>When it comes to exercise, the intensity of how hard you work out is just as important as the duration of your exercise session. In general, exercise intensity is divided into three categories:</p><ul><li>low</li><li>moderate</li><li>vigorous or strenuous</li></ul><p>For an activity to be vigorous, you need to work at 70 to 85 percent of your maximum heart rate, according to the<a href="https://www.heart.org/en/healthy-living/fitness/fitness-basics/target-heart-rates" target="_blank"> American Heart Association</a>. Examples of vigorous exercise include:</p><ul><li>running</li><li>cycling at 10 mph or faster</li><li>walking briskly uphill with a heavy backpack</li><li>jumping rope</li></ul><p>Low to moderate exercise is easier to sustain for longer periods since you work below 70 percent of your maximum heart rate and, sometimes, well below that level.</p><p>To reap health benefits, the <a href="https://www.hhs.gov/fitness/be-active/physical-activity-guidelines-for-americans/index.html" target="_blank">Physical Activity Guidelines for Americans</a> recommends that people age 18 and older get one of the following:</p><ul><li><strong>150 minutes</strong> of moderate-intensity aerobic activity per week</li><li><strong>75 minutes</strong> of vigorous aerobic activity per week</li><li><strong>combination of both types</strong> of activity spread throughout the week</li></ul>
Strenuous Exercise Vs. Moderate Exercise<p>Increasing your exercise intensity is fairly simple to do. You can still participate in your favorite activities — just at a more vigorous pace.</p><p>One of the benefits of more strenuous exercise is that you can reap the same rewards as moderate-intensity exercise but in less time. So, if time is of the essence, doing a more strenuous 20-minute workout can be just as beneficial as doing a slower 40-minute workout session.</p><p>Here are some examples of <a href="https://www.cdc.gov/nccdphp/dnpa/physical/pdf/pa_intensity_table_2_1.pdf" target="_blank">strenuous vs. moderate exercise<span></span></a>.</p><table><tbody><tr><th>Moderate intensity</th><th>Strenuous intensity</th></tr><tr><td>bicycling at less than 10 mph</td><td>bicycling at more than 10 mph</td></tr><tr><td>walking briskly</td><td>running, or hiking uphill at a steady pace</td></tr><tr><td>jog-walk intervals</td><td>water jogging/running</td></tr><tr><td>shooting baskets in basketball</td><td>playing a basketball game</td></tr><tr><td>playing doubles tennis</td><td>playing singles tennis</td></tr><tr><td>raking leaves or mowing the lawn</td><td>shoveling more than 10 lbs. per minute, digging ditches</td></tr><tr><td>walking stairs</td><td>running stairs</td></tr></tbody></table>
Benefits of Vigorous Exercise<p>Besides being more efficient, turning up the heat on your fitness sessions can benefit your health in a variety of ways. Let's take a closer look at some of the evidence-based benefits of a higher intensity workout.</p><ul><li><strong>Higher calorie burn.</strong> According to the <a href="https://www.acefitness.org/education-and-resources/professional/expert-articles/5008/7-things-to-know-about-excess-post-exercise-oxygen-consumption-epoc/?utm_source=Rakuten&utm_medium=10&ranMID=42334&ranEAID=TnL5HPStwNw&ranSiteID=TnL5HPStwNw-hYlKnAcfzfixAUsvnO6Ubw" target="_blank">American Council on Exercise</a>, working out at a higher intensity requires more oxygen, which burns more calories. It also contributes to excess post-exercise oxygen consumption (EPOC) or the "afterburn effect" that allows you to continue burning calories even after you finish working out. This means your metabolism will stay elevated for longer after a vigorous exercise session.</li><li><strong>More weight loss.</strong> A <a href="https://www.healthline.com/health-news/interval-workouts-will-help-you-lose-weight-more-quickly" target="_blank">higher calorie burn</a> and an elevated metabolism will help you lose weight more quickly than doing low- or moderate-intensity exercise.</li><li><strong>Improved heart health.</strong> According to a <a href="https://www.ncbi.nlm.nih.gov/pubmed/16377300" target="_blank">2012 study</a>, high- and moderate-intensity exercise appears to offer low chance of cardiovascular events, even in those with heart disease. Cardiovascular benefits may include improvements in:<ul><li><a href="https://www.healthline.com/health/diastole-vs-systole" target="_blank">diastolic blood pressure</a></li><li><a href="https://www.healthline.com/nutrition/15-ways-to-lower-blood-sugar#TOC_TITLE_HDR_1" target="_blank">blood sugar control</a></li><li>aerobic capacity</li></ul></li><li><strong>Improved mood.</strong> High-intensity exercise may also boost your mood. According to a large <a href="https://www.jstage.jst.go.jp/article/jpts/27/4/27_jpts-2014-736/_article" target="_blank">2015 study</a> that analyzed the data of more than 12,000 participants, researchers found a significant link between strenuous exercise and fewer depressive symptoms.</li><li><strong>Lower risk of mortality.</strong> According to a 2015 <a href="https://www.ncbi.nlm.nih.gov/pubmed/25844882" target="_blank">study</a>, researchers found that vigorous activity may be key to avoiding an early death. The study, which followed 204,542 people for more than 6 years, reported a 9 to 13 percent decrease in mortality for those who increased the intensity of their exercise sessions.</li></ul>
How to Measure Exercise Intensity<p>So, how do you know for sure that you're exercising at a strenuous level? Let's look at three ways to measure the intensity of your physical activity.</p><h3>1. Your heart rate</h3><p>Monitoring your heart rate is one of the most reliable methods for measuring exercise intensity. Exercising at 70 to 85 percent of your maximum heart rate qualifies as vigorous exercise intensity.</p><blockquote><strong><strong>WHAT IS YOUR MAXIMUM HEART RATE?</strong></strong>Your maximum heart rate is the fastest your heart can safely beat. To find out what your maximum heart rate is you need to subtract your age from 220. For example, for a 40-year-old person: <ul><li>220 bpm (beats per minute) minus age</li><li>220 – 40 = 180 bpm</li></ul>To work out at a vigorous pace, you'll want to exercise within 70 to 85 percent of your maximum heart rate. For example: <ul><li>180 x 0.70 (70 percent) = 126</li><li>180 x 0.85 (85 percent) = 153</li></ul>For a 40-year-old person, a vigorous training range is 126 to 153 bpm.<br></blockquote><p>You can check your heart rate while you're working out by wearing a heart rate monitor or <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">taking your pulse</a>.</p>
How to Add Vigorous Activity to Your Workout<p>Adding strenuous activity to your weekly workout routine requires some careful planning. Fortunately, many of the activities that you do at a moderate level can easily be performed at a higher intensity.</p><p>One way of incorporating vigorous aerobic activity into your routine is to do a <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workout. This type of workout combines short bursts of intense activity — typically performed at 80 to 95 percent of your maximum heart rate — with recovery periods at 40 to 50 percent maximum heart rate.</p><p>To sustain this level of training, consider following a 2:1 work to rest ratio. For example, a <a href="https://www.healthline.com/health/treadmill-weight-loss#hiit" target="_blank">treadmill workout </a>or outdoor running session could include:</p><ul><li>running at 9 to 10 mph for 30 seconds</li><li>followed by walking at 3 to 4 mph for 60 seconds</li><li>alternating this work-to-rest ratio for 20 to 30 minutes</li></ul><p>Playing a fast-paced sport like soccer, basketball, or racquetball is another effective way to add strenuous activity to your fitness routine. Participating in <a href="https://www.healthline.com/health/benefits-of-a-spin-class" target="_blank">cycling classes</a> or swimming laps are other ways to build more strenuous exercise into your workouts.</p>
Safety Tips<p>Before you turn up the intensity on your workouts, it's important to keep the following safety tips in mind.</p><h3>Check with your doctor</h3><p>If you have a health condition or you haven't been active in a while, make sure you talk to your doctor before you start a high-intensity exercise routine. Your doctor can advise you on a safe level of exercise or how to become more active in the safest way possible.</p><h3>Build up the intensity slowly</h3><p>Going from low- or moderate-intensity workouts to vigorous exercise requires time and patience. While you may be ready to jump in with both feet, the safest way to add more vigorous exercise is to do it in bite-size increments. Pushing yourself too quickly can result in injuries and burnout.</p><p>For example:</p><ul><li><strong>Week 1:</strong> Swap out one moderate-paced cardio session for a HIIT workout.</li><li><strong>Week 2:</strong> Swap one moderate-paced session with a HIIT workout, and also add a circuit strength training session to your weekly routine.</li><li><strong>Week 3 and 4: </strong>Repeat weeks 1 and 2 before you start adding more high-intensity exercise to your weekly routine.</li></ul><p>It's also a good idea to space out your vigorous workouts throughout the week. Try not to do two strenuous sessions back-to-back.</p><h3>Don't forget the recovery time</h3><p>Your body requires more time to recover from a vigorous workout compared to a low- or moderate-intensity session.</p><p>To help your body recover, make sure to always include a cooldown and <a href="https://www.healthline.com/health/exercise-fitness/static-stretching" target="_blank">stretch routine</a> after strenuous physical activity.</p><h3>Stay hydrated</h3><p><a href="https://www.healthline.com/nutrition/7-health-benefits-of-water" target="_blank">Staying hydrated</a> is especially important when you're exercising hard. Not drinking enough fluids can affect the quality of your workout and make you feel tired, lethargic, or dizzy. It may even lead to <a href="https://www.healthline.com/health/dehydration-headache" target="_blank">headaches</a> and <a href="https://www.healthline.com/health/pain-relief/how-to-stop-leg-muscle-cramps" target="_blank">cramps</a>.</p>
The Bottom Line<p>Turning up the intensity of your workout sessions can be an effective way of boosting your overall health and fitness. It's also an easy way to save time when trying to fit a workout into your day.</p><p>To play it safe, always start slow and pay attention to how your body feels.</p><p>While vigorous exercise offers many health benefits, it's not appropriate for everyone. If you have a health condition or you haven't been active in a while, make sure to talk with your doctor before working out at a more strenuous level.</p>
