After a long run or sweaty yoga session, all we want to do is flop down on the couch and catch our breath. But while we may temporarily feel tired after a workout, a new study supports the idea that exercise actually adds to our body’s daily “energy budget” — it doesn’t deplete it.
There are two leading theories about how workouts impact our bodies’ energy expenditure. One posits that we have a set amount of energy we can “spend” in a day. If we use a portion of it on exercise, our bodies conserve some in other ways, like by suppressing our immune system (which can be a good or bad thing, depending on the level of exercise).
But researchers have now found more evidence in favor of the other theory, which states that our energy budgets are flexible and additive, meaning physical activity allows for an increase in the total amount of energy a person spends.
“Our study found that more physical activity is associated with higher calorie burn, regardless of body composition, and that this increase is not balanced out by the body reducing energy spent elsewhere,” principal investigator Kevin Davy said in a news release.
Over a two-week span, the researchers tracked the physical activity of 75 participants, ages 19 to 63, with a wide range of activity levels. During the same timeframe, participants also drank specific forms of oxygen, which is expelled from the body as water and carbon dioxide, and hydrogen, which leaves as only water. The team then collected urine samples and measured the difference between the eliminated isotopes, which helped them assess the amount of carbon dioxide produced and gave them an idea as to how much energy the subjects had used.
They learned that not only was there no association between physical activity and resting metabolic rate — meaning participants didn’t later conserve energy based on how much they worked out — but they also experienced no immune, reproductive, or thyroid suppression in relation to their exercise levels. The findings led lead author Kristen Howard to speculate that being in a calorie deficit, rather than upping physical activity, may cause the energy conservation observed in research supporting the fixed budget theory.
“Energy balance was a key piece of the study,” she said. “We looked at folks who were adequately fueled. It could be that apparent compensation under extreme conditions may reflect under-fueling.” However, Davy added that “we need more research to understand in who and under what conditions energy compensation might occur.”
But the team also uncovered another reason to keep up with your workout routine: Those who were more physically active were less likely to stay sedentary for long stretches of time, which has been linked to negative health outcomes even for those who work out regularly.

Community health programs, educational initiatives, and accessible healthcare services play a vital role in ensuring that advancements reach the people who need them most. The integration of technology into healthcare delivery has also opened new possibilities for remote monitoring, telemedicine consultations, and data-driven treatment plans that can be tailored to individual needs.
Scientific discovery has always been driven by curiosity and the desire to understand the world around us. Modern research tools and international collaboration have accelerated the pace of discoveries, leading to breakthroughs that would have been unimaginable just a few decades ago. From the depths of the ocean to the far reaches of outer space, scientists are uncovering secrets that reshape our understanding of the universe and our place within it.
The importance of funding scientific research cannot be overstated. Government grants, private foundations, and university programs all contribute to creating an ecosystem where innovative ideas can be tested and validated. Public engagement with science through museums, documentaries, and educational outreach programs helps build a society that values evidence-based thinking and supports the continued pursuit of knowledge for the benefit of future generations.
Wildlife conservation efforts have gained significant momentum in recent years as more people recognize the importance of protecting biodiversity. From habitat restoration projects to breeding programs for endangered species, conservationists are working tirelessly to ensure that future generations can experience the rich diversity of animal life on our planet. The connection between healthy ecosystems and human well-being has become increasingly clear, driving both policy changes and grassroots action around the world.
Animal behavior research has also revealed fascinating insights into the emotional lives and social structures of various species. Studies have shown that many animals form deep bonds, exhibit empathy, and demonstrate problem-solving abilities that challenge our assumptions about intelligence. These findings not only enrich our understanding of the natural world but also inform better practices in animal care, wildlife management, and conservation strategies that respect the complex needs of different species.
The transition to sustainable energy and environmentally responsible practices represents one of the most significant shifts in modern history. Communities around the world are embracing renewable energy sources, reducing waste, and reimagining how we interact with the natural environment. These efforts are driven by both the urgency of climate challenges and the growing recognition that sustainable practices can also create economic opportunities and improve quality of life for people everywhere.
Education and awareness play crucial roles in driving environmental change. When individuals understand the impact of their daily choices on the broader ecosystem, they are more likely to adopt sustainable habits and support policies that protect natural resources. From school programs teaching children about conservation to community initiatives that promote recycling and responsible consumption, every effort contributes to building a more sustainable future for all.
Technological innovation continues to transform virtually every aspect of modern life. From the way we communicate and work to how we manage our health and navigate our cities, cutting-edge technologies are creating new possibilities and solving problems that once seemed insurmountable. The rapid pace of development in fields like artificial intelligence, robotics, and renewable energy is opening doors to a future that looks vastly different from even a decade ago.
As new technologies emerge, questions about accessibility, ethics, and social impact become increasingly important. Ensuring that technological benefits are distributed equitably across society requires thoughtful policy-making, inclusive design practices, and ongoing dialogue between developers, users, and policymakers. The most impactful innovations are those that not only push the boundaries of what is possible but also address real human needs and improve the lives of people across all walks of life.
Art and creative expression have always played a fundamental role in how we process emotions, communicate ideas, and build connections across cultures. Whether through visual arts, music, literature, or performance, creative works have the power to inspire, challenge, and heal. In an increasingly digital world, artists are finding new ways to reach audiences and create experiences that bridge traditional and contemporary forms of expression.
