CNN Health Exhausted? The reason may be how you're using technology

Analysis by Kara Alaimo

Oct 7, 2025

Kara Alaimo is a professor of communication at Fairleigh Dickinson University. Her book "Over the Influence: Why Social Media Is Toxic for Women and Girls — And How We Can Take It Back" was published in 2024 by Alcove Press.

You may think you're exhausted because, like me, you have too many things on your plate. But there's another reason, according to a new book.

Case in point: While | was writing this piece, | responded to dozens of emails from colleagues and students, got a huge medical bill, replied to a text about a home repair, and learned that my older daughter needs to wear white to school next Monday while the younger one is supposed to wear the colors of fall.

This relentless barrage of interruptions and switching between thoughts and technology platforms is leaving us utterly exhausted, says Paul Leonardi, department chair and Duca Family Professor of Technology Management | at the University of California, Santa Barbara.

He explains how this happens in his new book, "Digital Exhaustion: Simple Rules for Reclaiming Your Life."

| spoke to Leonardi about what's making us all so tired | and what we can do about it.

CNN: You say one reason we're so exhausted is that we keep switching between platforms. How does that make us exhausted?

Paul Leonardi: Every tool we use requires some amount of cognitive focus. We have to learn the tool we're enmeshed in. When we switch, we have to disengage | and reengage in another area of focus, and we also have to switch how we're using that tool. Our brains do not do a good job of switching that quickly. The main issue is that we haven't evolved to make the switches as quickly as we do today. It leaves us feeling exhausted.

CNN: You found that we often don't realize we're getting exhausted from all this digital switching. Why?

Leonardi: It comes back to the way our bodies have evolved over time. We have good sensory feedback to show us when we're physically tired. Otherwise, we could collapse, and that's dangerous. So, our body knows to send signals to our brain to say stop. But we didn't evolve to sit in an office in front of a computer, so our brain doesn't know to tell itself it's tired. We can just keep taxing ourselves, but that residue builds up over time. Then we feel like we've been hit by a semitruck

CNN: What can we do to address that exhaustion?

Leonardi: Think about reducing the kinds of switches we make throughout the day.

In the book | talk about three kinds of switches. Switching between modalities is switching across tools. Think about the different videoconferencing platforms you use. You might use Zoom and then switch to Microsoft Teams. They seem like they're roughly the same. But how many times have you been in a meeting and thought, "I need to share my screen. How do | do that on this platform?" And those little changes are enough to really wear us out when they accumulate over time

The second type is what | call switches between domains, and that's when we're working on one task, get interrupted and then switch to a different task. The unplugging and then re-plugging into the other task take quite a bit of effort. It's a tremendous tax that we pay.

The third type is switching between different areas of life. How many times in your day are you getting a quick text from your kid's school? Or the plumber calls to tell you they're going to be late and wants to talk about the problem in your house. Those switches across really big domains are even more exhausting because they pull us completely out of our thought process in one area, and then we have to get back.

CNN: You say social media is the most exhausting type of platform to use. Why?

Leonardi: | talk about three forces that exhaust us. One is attention. On social media we're constantly switching between things because apps are pushing us different notifications. First somebody liked something, and then there's an ad. The second force of exhaustion is making inferences. We get a snippet of data, and it's not quite enough to tell us the whole picture. So, we have to fill in the blanks, and that takes effort. On social media we're constantly different apps and making inferences. We see somebody is on a trip, and we're like, they must have a lot of money. And they're having the time of their life. We're filling in the blanks.

The last is emotion. When our emotions get piqued, whether for good or for bad, that's also exhausting. On social media we do social comparisons, so we get jealous that somebody else is doing something we wish we were doing. Or we get annoyed that we see a bunch of friends hanging out and we're not part of the group.

Social media is so exhausting because it maximizes all three of these forces.

CNN: You say it's especially hard for people who work from home to avoid this kind of exhaustion. Why is that? Leonardi: One of the big reasons remote workers experience exhaustion even more than people in the office — or it feels more acute — is that it's very difficult to create separation between work and home. They're constantly trying to manage that boundary, and that's so exhausting.

They also are more dependent on tools for everything, so they don't get a break. If you're in the office and you have an in-person meeting, you don't have to switch onto your Zoom platform. You actually get a break for a little bit when you're talking to somebody in the hallway. You don't get that on these tools.

You're also managing your presence when you're working from home. You need to make sure people know you're available because it matters for people's perception of your work performance. So, you're putting on a sort of act that's also exhausting

CNN: You recommend turning off the video of ourselves in meetings. Why?

Leonardi: | think it's a good idea sometimes. We tend to fixate on ourselves, and doing that creates a feeling of self-consciousness. It also creates more effort for us to manage our presentation to others.

Imagine if you were talking to friends, or you're in a meeting, and you have a mirror in front of your face the entire time. You're like, oh my gosh, how do | look right now? There are bags under my eyes, and | can't believe | made that stupid facial expression. We don't do that in regular life.

These extra little activities accumulate to wear us out over time.

Communicating in person instead of texting, when possible, can reduce digital exhaustion and create richer relationships.

CNN: What's your best advice for parents who are exhausted from keeping up with endless group chats about car pools and soccer games?

Leonardi: | never intended to write about that in my book, but it came up so often in the interviews | did.

One strategy | heard that was quite effective was calculating whether a car pool is actually worth the time you're putting into coordinating it. If you add up all the time you're spending texting with other people, sometimes it adds up to the same amount of time it would take to just drive your kid yourself.

Another strategy people used was reducing those communications by trying to coordinate in person. When they see each other at the soccer game, they have a long conversation about the plan for the next week. A lot of folks find they're developing richer relationships because that discussion about the car pool is just the entrée to a deeper conversation. Those are much more fulfiling relationships than the transactions taking place via text

Driven by pre-salt, oil becomes Brazil's top export

Revenues

The discovery of the pre-salt was so significant for Brazil's oil production potential that it led the government to change the regime that authorized companies to explore the submerged resources.

As a result, the pre-salt areas are governed by the sharing regime. Under this model, surplus oil production—the balance after covering costs—is divided between the company and the Brazilian government. During the auction that authorizes exploration, the company offering the highest share of profits to the federal government is granted the right to explore.

This is distinct from the concession model, which applies to the post-salt period. In this system, the risk of investment and exploration lies with the concessionaire, who becomes the owner of all the oil and gas that may be discovered. In return, the company pays royalties and special participation fees, particularly for large production fields, in addition to a signature bonus upon winning the auction.

New frontiers

With the pre-salt expected to reach its peak in the 2030s, Brazil's oil industry, led by Petrobras, is shifting its focus to new oil frontiers that are believed to hold significant production potential.

One such frontier is the so-called equatorial margin, located off Brazil's northern coast, where exploration is pending a favorable decision from the Brazilian Institute for the Environment and Renewable Natural Resources (Ibama), an agency under the Ministry of the Environment and Climate Change.

Another promising region is the Pelotas Basin, located off Brazil's southern coast. The growing interest in this area is fueled by the discovery of oil wells in Uruguay and off the coasts of Namibia and South Africa. Experts suggest that the geological conditions in these regions are similar, as the continents were once joined tens of millions of years ago.

According to Petrobras, the company plans to invest $79 billion in exploring new oil and gas frontiers by 2029. Of this amount, 40 percent will be allocated to the South and Southeast regions, 38 percent to the equatorial margin, with the remainder directed towards other countries.
