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

Phrasal verbs are a prime example of how combining a verb with a particle can create multiple meanings, often idiomatic, which challenge learners of English as a second language. Regarding the contextual meanings of the verb "take" combined with different particles, mark T for True and F for False:
(__)"Take after" means to resemble a parent or ancestor in appearance or character.
(__)"Take off" can mean to remove clothing or for an aircraft to leave the ground.
(__)"Take over" means to assume control or responsibility for something.
(__)"Take up" means to refuse an offer or invitation politely.
Choose the alternative that presents the correct sequence, from top to bottom.
(__)The modal verb "must" in "He must be exhausted after the marathon" expresses epistemic necessity (logical deduction), not obligation.
(__)In the sentence "The theory, that I described earlier, is complex," the use of "that" is grammatically correct for a non-restrictive clause.
(__)The pronoun "whom" is mandatory, in formal English, when it functions as the complement of a preposition (e.g., "The person to whom I spoke").
(__)The conjunction "lest" is followed by the subjunctive mood or "should", expressing a negative purpose (e.g., "Lest he forget").
Select the alternative that presents the correct sequence, from top to bottom.
Choose the correct option to complete the sentence.
“By the end of the week, the committee ______ its final decision.”
Choose the alternative that correctly completes the sentences below.

The verb “condenses” in the passage is used as:
After years of internal resistance and strategic miscalculations, the company was forced to ______ its traditional business model when emerging technologies began to undermine its market dominance. Although executives initially attempted to dismiss the changes as temporary, mounting financial pressure eventually compelled them to reconsider their longterm strategy.
The engineers presented the prototype only after they ______ every limitation identified during the preliminary trials.
The unusually meticulous design of the prototype clearly ______ a level of foresight that was uncommon for the technological standards of the period.
“The company became synonymous with film photography because it controlled every stage of the process.”
Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce. Modern cryptography techniques include algorithms and ciphers that enable the encryption and decryption of information, such as 128‑bit and 256‑bit encryption keys. Modern ciphers, such as the Advanced Encryption Standard (AES), are considered virtually unbreakable.
A common cryptography definition is the practice of coding information to ensure only the person that a message was written for can read and process the information. This cybersecurity practice, also known as cryptology, combines various disciplines like computer science, engineering, and mathematics to create complex codes that hide the true meaning of a message. Cryptography can be traced all the way back to ancient Egyptian hieroglyphics but remains vital to securing communication and information in transit and preventing it from being read by untrusted parties. It uses algorithms and mathematical concepts to transform messages into difficult‑to‑decipher codes through techniques like cryptographic keys and digital signing to protect data privacy, credit card transactions, email, and web browsing.
Cryptography remains important to protecting data and users, ensuring confidentiality, and preventing cyber criminals from intercepting sensitive corporate information. Individuals and organizations use cryptography on a daily basis to protect their privacy and keep their conversations and data confidential. The technique ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted. It also secures browsing, such as with virtual private networks (VPNs), which use encrypted tunnels, asymmetric encryption, and public and private shared keys.
Similar to how cryptography can confirm the authenticity of a message, it can also prove the integrity of the information being sent and received. The technology also ensures information is not altered while in storage or during transit between the sender and the intended recipient. For example, digital signatures can detect forgery or tampering in software distribution and financial transactions.Cryptography confirms accountability and responsibility from the sender of a message, which means they cannot later deny their intentions when they created or transmitted information. Digital signatures are a good example of this, as they ensure a sender cannot claim a message, contract, or document they created to be fraudulent. Furthermore, in email nonrepudiation, email tracking makes sure the sender cannot deny sending a message and a recipient cannot deny receiving it.
There are many types of cryptographic algorithms available. They vary in complexity and security, depending on the type of communication and the sensitivity of the information being shared.
