TL;DR. English has two words for states that often get treated as one: solitude, which you choose, and loneliness, which you did not. The research separates them sharply. Experimental studies find that being alone leads to relaxation and reduced stress specifically when people actively choose to be alone. Meanwhile the World Health Organization’s 2025 report finds that unwanted loneliness affects one in six people worldwide and is associated with more than 871,000 deaths a year. This piece gives you a framework for telling which side you are on, because the person who cannot make that distinction ends up avoiding the version that would have helped.
Why the distinction matters
An earlier version of this article suggested a few activities to make time alone more enjoyable. The suggestions were not bad, but they left one assumption untested: that every form of being alone is good for you.
The research does not support that assumption. The two states are structurally different, and the single variable that separates them is choice.
What happens when you decide to switch off your phone and spend two hours alone is not the same experience as spending two hours alone because nobody called. An observer cannot tell the difference. Your body can.
The CEOtudent lens is useful here. A CEO schedules quiet as a resource. A student observes what the quiet actually does and adjusts. Neither is simply subjected to being alone. Both decide on it.
What the research says
Thuy-vy Nguyen, Richard Ryan and Edward Deci examined the effect of being alone on emotional experience across four studies published in Personality and Social Psychology Bulletin.
The core finding is more interesting than expected. Solitude generally produces a deactivation effect: it decreases both positive and negative high-arousal affect together. Being alone does not merely calm you down; it also lowers excitement. That explains why quiet sometimes feels like peace and sometimes like emptiness.
The details matter too. In the first study, the deactivation effect occurred when people were alone but not when they were with another person. The second study showed the effect did not depend on whether the person was engaged in an activity such as reading while alone. In the third, high-arousal positive affect did not drop when participants specifically engaged in positive thinking, or when they actively chose what to think about.
And the fourth study produced the finding this whole article rests on: solitude could lead to relaxation and reduced stress when individuals actively chose to be alone.
Choice is not a decorative detail. It is the condition under which the effect appears at all.
The other side of the coin
Unchosen aloneness is a different category entirely, and it is now a matter of health policy.
The World Health Organization’s Commission on Social Connection published its report, “From loneliness to social connection: charting a path to healthier societies”, on 30 June 2025. It reports that one in six people worldwide is affected by loneliness, and that loneliness is linked to roughly 100 deaths every hour, more than 871,000 deaths a year.
Data on social isolation is more limited, but the report estimates it affects up to one in three older adults and one in four adolescents. The report followed the first resolution on social connection, adopted by the World Health Assembly in May 2025.
The purpose of these figures here is not alarm. It is to draw a boundary. Chosen solitude is a resource; unchosen loneliness is a health risk, and waving the second away with “a bit of alone time is good for you” is a mistake.
Chosen solitude versus unwanted loneliness
CEOtudent editorial framework. The findings in the left column come from Nguyen, Ryan and Deci; the figures in the right column from the report of the WHO Commission on Social Connection.
| Dimension | Chosen time alone | Unwanted loneliness |
|---|---|---|
| Defining feature | The person actively chooses to be alone | The state is imposed on the person |
| Emotional effect | Reduces both positive and negative high-arousal affect | Persistent distress; associated with health risk |
| Measured outcome | Relaxation and reduced stress where choice is present | Associated with more than 871,000 deaths a year, roughly 100 an hour |
| Prevalence | A matter of personal preference | One in six people worldwide |
| Correct response | Schedule it and protect it | Build connection; not simply getting used to it |
The hourly figure is consistent with the report’s annual total: 871,000 deaths divided across the 8,760 hours in a year works out to roughly 99 an hour.
Making time alone actually work
The suggestions in the earlier version were well meant but did not explain what makes the difference. What the research points to is simpler and more demanding.
First, make sure it is a choice. This is not item one on the list; it is the precondition. Did you choose the time you spend alone, or did it simply appear in your calendar? If it is the second, the first job is not to fill that time but to look at why it is there.
Disconnect, but decide the length in advance. Open-ended solitude turns into avoidance easily. The difference between forty-five deliberate minutes alone and “I did not speak to anyone today” is the decision itself.
Expect the excitement to drop too. This is the most practical finding in the research. Being alone lowers not only tension but also enthusiasm. Someone who does not know this mistakes the dip in the middle of the quiet for a bad sign and abandons the session. The dip is an expected effect, not a malfunction.
Choose what to think about. In the third study, participants who actively chose what to think about did not show the drop in positive affect. Entering time alone with a question produces a different result from entering it with an empty mind. One question is enough: what did I frame wrongly this week, what should I drop next month.
You do not have to be busy. The second study showed the effect did not depend on being engaged in an activity such as reading. You do not need to fill the time to look productive; the effect comes from being alone, not from the activity.
Know the limit. Time alone is a tool for recovery, not a substitute for connection. Going weeks without seeing anyone is not deep work. The WHO data shows exactly why this boundary matters.
Frequently asked questions
Is it a problem to enjoy being alone?
No. The research finds relaxation and reduced stress in people who choose to be alone. The problem begins where the solitude was not chosen. The diagnostic question is not “do I like being alone” but “did I choose this”.
Why do I sometimes feel worse when I am alone?
One likely explanation is directly in the research: solitude lowers high-arousal affect in both directions. Your tension falls, but so does your liveliness, and that drop can read as feeling worse. The second possibility is that the solitude was not chosen, in which case what you are feeling is isolation rather than rest.
How much time alone is right?
The research does not prescribe a duration, so we will not invent one. The workable test is not length but choice and boundary: did you set the time, and do you return to connection when it ends.
Is loneliness really a health risk?
The 2025 report of the WHO Commission on Social Connection associates loneliness with more than 871,000 deaths a year and reports that it affects one in six people worldwide. These are association estimates, but they carry enough weight to move the topic out of personal preference and onto the public health agenda.
Should I be doing something while I am alone?
Not necessarily. One of the studies showed the effect did not depend on whether the person was engaged in an activity while alone. Choosing what to think about does make a difference, though, which is why bringing a question works better than bringing a task.
Do I have to switch off social media?
This is a definitional point rather than a moral rule. You can technically be alone while attached to a notification feed, but the measured effect of solitude assumes a state in which your attention is not on other people. With the connection open you are not alone; there simply is nobody next to you.
