A Mind at Ease: Mental Wellbeing, Rest and Release from Stress

Introduction

There is a particular kind of tiredness that sleep does not cure. It is the tiredness of Sunday evenings, of the phone that is checked last thing at night and first thing in the morning, of the meeting that replays itself at three o’clock in the morning. Many people carry it for so long that they stop noticing it. It simply becomes the weather of their working lives.

This chapter is about what happens when that weather lifts. It asks whether leaving work early — on one’s own terms, with enough money to live on — brings relief from stress, deeper and more restful sleep, less fatigue, fewer depressive symptoms and a greater sense of satisfaction with life. It draws on some of the largest and longest studies ever conducted of people moving from work into retirement, from French gas and electricity workers to Finnish public servants and British civil servants, and on the testimony of people who made that leap in their thirties, forties and fifties.

The evidence on mental wellbeing is, if anything, more encouraging than the evidence on physical health. Study after study finds that sleep improves, fatigue falls away dramatically, and depressive symptoms become less common after people retire. But there is an important condition attached, and it recurs throughout the chapter: these benefits belong overwhelmingly to people who choose to retire. Those who are pushed out — by ill health, redundancy or circumstance — tell a different story. And even for those who leave freely, peace of mind is not automatic. It must be accompanied by purpose, connection and the patience to let a new rhythm settle.

What the research tells us

Sleep: a nightly dividend

Among the most striking findings in the whole literature on retirement concerns sleep. Vahtera et al. (2009) followed 14,714 employees of France’s national gas and electricity company in the GAZEL cohort, with annual measurements from seven years before to seven years after retirement — a mean of twelve measurements per person. In the years before retirement, between 22.2% and 24.6% of participants reported disturbed sleep. After retirement, the odds of having a sleep disturbance fell substantially (odds ratio 0.74) compared with the pre-retirement period. The improvement was greater in men than in women and in higher-grade than lower-grade workers, and, crucially, it was sustained over the post-retirement years. The authors concluded that removal of work-related exposures was the likely mechanism, and that repeated measurements provided ‘strong evidence for a substantial and sustained decrease in sleep disturbances following retirement’ (Vahtera et al., 2009, p. 1459).

Research in Finland has since confirmed and refined this picture. Using the Finnish Public Sector study, Myllyntausta et al. (2017) followed 5,785 people who retired on a statutory basis and found that average sleep duration rose from seven hours to seven hours and 22 minutes across the retirement transition, then stayed at that level. The increase was greatest among those who had been short sleepers or who had sleep difficulties before retiring. A companion study of 5,807 retirees found that 30% had sleep difficulties just before retirement, and that the risk fell during the transition — particularly for waking too early in the morning and for non-restorative sleep, which almost halved (Myllyntausta et al., 2018). The benefits were concentrated among people who had experienced psychological distress, job strain or short sleep before they left work.

Economists have found the same pattern. In Germany, Eibich (2015) used a regression-discontinuity design based on pension incentives and identified longer sleep as one of the key mechanisms through which retirement improved subjective and mental health, alongside relief from work-related stress and more frequent exercise.

Fatigue lifts, and depressive symptoms fall

If sleep improves, so too does the daytime experience of energy. In another GAZEL analysis, Westerlund et al. (2010) looked at mental fatigue, physical fatigue and depressive symptoms in 11,246 men and 2,858 women. Retirement was associated with a substantial decrease in both mental fatigue (odds ratio 0.19 for fatigue one year after versus one year before retirement) and physical fatigue (0.27). Depressive symptoms also fell markedly (0.60). Remarkably, the reduction in fatigue was more pronounced among people who had a chronic disease before they retired — suggesting that for those managing an illness, work itself had been a heavy additional load.

A broader view comes from a meta-analysis by Odone et al. (2021), which pooled 41 studies and more than half a million people. Retirement was associated with a lower risk of depression (effect size 0.83), and the protective association grew stronger — to around 0.76 — when the analysis was restricted to high-quality, longitudinal studies using validated measures. The authors, cautious about the high heterogeneity between studies, nonetheless concluded that pooled data suggested retirement reduces the risk of depression by nearly 20%. An earlier systematic review of 22 longitudinal studies likewise found strong evidence that retirement benefits mental health (van der Heide et al., 2013).

Objective records point the same way. Oksanen et al. (2011) used Finland’s comprehensive national pharmacy records to track antidepressant purchases among 7,138 public-sector employees who retired at statutory age. Antidepressant use fell during the retirement transition (prevalence ratio 0.77 one year after versus one year before retirement), a pattern the authors described as consistent with the hypothesis that retirement is beneficial for mental health.

Better mental health — especially when retirement is chosen

The British Whitehall II study of civil servants provides some of the clearest evidence on early retirement specifically. Mein et al. (2003) compared civil servants who retired at 60 with those who carried on working and found that mental health functioning deteriorated among those who continued to work but improved among the retired, particularly in higher employment grades. Jokela et al. (2010), following 7,584 civil servants across fifteen years, found that statutory retirement at 60 and early voluntary retirement were each associated with mental health scores around 2.2 points higher than continued employment. Within-person analyses supported a causal interpretation. Retirement due to ill health, by contrast, was not associated with improvement.

Why might work weigh so heavily on the mind? Part of the answer lies in the nature of modern work. A meta-analysis combining published and unpublished data from more than 120,000 people found that job strain — the combination of high demands and low control — was associated with an increased risk of clinical depression (Madsen et al., 2017). Another found a small association between long working hours (typically 55 or more a week) and the onset of depressive symptoms in Europe, and a moderate one in Asia (Virtanen et al., 2018). For many people, early retirement is quite simply the removal of a known psychological hazard.

The most recent evidence directly addresses timing. In the Swedish HEARTS study of 5,913 people aged 60 to 74, Hansson et al. (2025) found average improvements across mental, physical and cognitive health after retirement, with more pronounced benefits among those who retired early. Those who retired at 61 showed notable reductions in depressive symptoms and gains in life satisfaction. The authors describe the effects of retirement as driven by ‘push (out of work) and pull (into retirement) factors’ (Hansson et al., 2025): people drawn towards a life they want tend to flourish, while those pushed out, or who deeply valued their work, are more vulnerable.

Life satisfaction and the importance of choice

Beyond the absence of distress lies something more positive: satisfaction with life. In a six-year Dutch study of 1,388 older workers, Hershey and Henkens (2014) found that people who left work voluntarily reported higher life satisfaction than those who stayed employed, whereas those whose departure was involuntary — for health or organisational reasons such as downsizing — reported the lowest satisfaction of all. It is hard to imagine a clearer endorsement of the central idea of this book: that the freedom to choose when and how to stop is itself a source of wellbeing.

Mind and body, moving together

One of the quiet themes running through this research is that mental and physical wellbeing after retirement rise and fall together. In the Finnish Retirement and Aging study, Tuominen et al. (2025) followed 3,535 public-sector workers with annual surveys before and after retirement. People whose life satisfaction increased across the transition — particularly those who had started from a low or intermediate level — also tended to increase their leisure-time physical activity, while those whose satisfaction fell tended to become less active. The study cannot say which comes first, but it suggests a virtuous circle: a happier mind makes it easier to move, and (as Chapter 1 showed) more movement supports a healthier body.

The same interplay appears in the German evidence. Eibich (2015) found that retirement not only improved self-reported mental health but also reduced visits to outpatient care, and identified relief from work-related stress and strain, longer sleep and more frequent exercise as the likely pathways. In the GAZEL cohort, the fall in fatigue at retirement was greatest among people living with a chronic disease (Westerlund et al., 2010). For these workers, the end of work did not cure their condition, but it removed a burden that had been draining their energy day after day. It is a helpful way to think about what early retirement can offer the mind: not an escape from every difficulty, but the removal of one large and often invisible load, leaving more energy for everything else.

This matters for anyone planning an early exit. The research does not suggest that retirement, in itself, produces lasting contentment. It suggests that retirement creates room — for sleep, for movement, for relationships and for purposeful activity — and that people who use that room well are the ones whose wellbeing continues to grow. The stories later in this chapter show how differently people have filled it.

Many paths through the transition

Research also suggests that retirees do not all follow the same path. Using the US Health and Retirement Study, Wang (2007) identified several distinct patterns of psychological wellbeing through the retirement transition, co-existing within the same population, and argued that the resources people bring with them — financial, social, and personal — help explain who thrives and who struggles. Adjustment is not a single event but a process, and it can be shaped.

Lives enriched: real stories

Tanja Hester — learning what ‘unstressed’ feels like

Tanja Hester, author of the book Work Optional and the Our Next Life blog, retired with her partner Mark Bunge at the end of 2017, at the ages of 38 and 41 (Hester, no date). Nine months later she wrote a thoughtful reflection on what had happened to her stress and sleep. While working, she explained, they had carried ‘a low level of work stress’ at virtually all times, and had been in a constant state of sleep deprivation, possibly for the whole fourteen years they had known each other (Hester, 2018a).

Early retirement changed both — though not quite as she expected. Her baseline stress fell so far that small stresses now stood out, just as a light drizzle feels like an event in the desert. ‘The baseline is healthier,’ she wrote, ‘but my perception of stress is perhaps greater’ (Hester, 2018a). Similarly, having finally caught up on sleep, she found she noticed tiredness more when she lost even a little of it. She was emphatic, though, about the overall direction: the point was not to say she felt more stressed and tired than ever, ‘Because I don’t. Not even a little bit’ (Hester, 2018a). Her insight — that a healthier mind becomes more sensitive, not less, to strain — is a subtle and hopeful one. It suggests that one of the gifts of early retirement is simply the ability to notice how we feel.

Joe Udo — from panic attacks to peace

Joe Udo, who writes the Retire by 40 blog, spent sixteen years in chip design and validation at Intel before retiring from engineering in 2012 at the age of 38 (Udo, no date). His description of his final working years is stark. ‘I was very stressed out before I left my engineering career and it was negatively affecting my health,’ he writes. He had headaches all the time, painfully tight shoulders, blurry eyes from ten or more hours a day at a screen and a sore back from sitting too long — and ‘the stress was causing panic attacks and depression’ (Udo, 2023).

Looking back, he reports that he feels ‘much better’ (Udo, 2023). He is candid that being self-employed as a blogger is not completely stress-free, though he notes that being in a good financial position helps with the stress too; the relentless strain that had been eroding his health, however, lifted. His experience mirrors the Finnish finding that the greatest improvements in sleep and wellbeing after retirement occur among those who experienced psychological distress and job strain beforehand (Myllyntausta et al., 2018).

Barney Whiter — rediscovering laughter

Barney Whiter, a British chartered accountant who blogs as The Escape Artist, paid off his mortgage at 32 and quit his corporate finance job in 2014 at the age of 43, while supporting a family of five (Whiter, no date). In an interview about his career change, he explained that there had been a time when he hated his job and felt like he was ‘hanging on by my fingertips’ (Knight, 2019).

Asked how freedom feels, his answer was about joy rather than money. He described feeling grateful to wake up without an alarm and not to have to board ‘a soulless, grey-suited commuter train’, and reflected that ‘the fun and humour had been slowly squeezed out of my life in the corporate world’ (Knight, 2019). Now, he said, he laughs a lot more than he used to. Importantly, he did not stop at rest: after a period to ‘decompress’, he found meaning, purpose and challenge through writing, teaching and coaching others (Knight, 2019). His story captures the research finding that voluntary retirement brings the greatest gains in life satisfaction (Hershey and Henkens, 2014) — and the wisdom of pairing rest with renewed purpose.

Doug — a health scare, a stressful job, and a very happy time of life

Doug, who writes the UK blog Maturing Well, retired from a stressful job with a local council in 2018 at the age of 56 — around a decade before his state pension age. He describes it as ‘one of the best decisions I have ever made’, saying his health has improved and that retirement ‘is turning out to be a very happy time of life’ (Maturing Well, no date). The decision was crystallised by an unexpected hospital admission, which brought thoughts of early retirement that he and his wife Rachel had been considering ‘clearly into focus’ (Maturing Well, 2019a).

A year on, he wrote honestly that he still had health challenges, but that having replaced his stressful full-time job with a variety of other things, ‘I do feel the benefit in terms of my general well-being’ (Maturing Well, 2019a). He also admitted that at one stage he had simply replaced his salaried career with a range of voluntary roles that were stressful in their own way, and had had to correct the balance. His blog records the quieter pleasures of the new life: a canal-boat holiday where travelling at four miles an hour felt ‘almost hypnotic’, and the news of the world seemed ‘so distant’ (Maturing Well, 2019b). His story is a reminder that early retirement can be a way of protecting one’s health after a warning sign — and that stress can creep back in unless boundaries are kept.

Leif Dahleen — the pager falls silent

Leif Dahleen, whose physical transformation appears in Chapter 1, also wrote vividly about the mental side of leaving medicine at 43. For more than twenty years, as a hospital-based physician, fragmented and unpredictable sleep had been the norm. ‘I sleep much, much better now,’ he writes; he never goes to sleep wondering whether he will get one, four or six hours before the pager summons him, and ‘Waking up naturally is a beautiful thing’ (Dahleen, 2022). He reported averaging around eight and three-quarter hours of sleep a night over one recent week.

He is characteristically measured about happiness. He considers himself happier and less stressed, ‘but it’s not all puppy dogs, ice cream, and rainbows’, and he warns that people whose identity is wrapped up in their profession, or whose social life revolved around work, may feel lost or lonely after early retirement (Dahleen, 2022). His experience of sleep sits neatly alongside the GAZEL and Finnish data: the relief of retirement is often most visible at night, once the burden of work has been lifted (Vahtera et al., 2009; Myllyntausta et al., 2017).

A balanced view

The research on mental wellbeing and retirement is among the most positive in this book, but it would be dishonest to present it as universal.

First, and most importantly, the benefits depend on how people leave work. Those who retire for health reasons do not share in the improvements, and in the GAZEL study they were the one group whose sleep disturbances increased after retirement (Vahtera et al., 2009). In Whitehall II, retirement due to ill health was associated with poorer mental health, though largely reflecting the illness rather than retirement itself (Jokela et al., 2010). Involuntary departures — through ill health or organisational reasons such as downsizing — were linked with the lowest life satisfaction in the Dutch study by Hershey and Henkens (2014). In the Swedish HEARTS study, high pre-retirement job satisfaction and involuntary retirement increased the risk of negative changes in mental health, particularly for those retiring later (Hansson et al., 2025).

Second, not every study finds benefit. Using data from ten European countries and an instrumental-variable design based on state pension ages, Heller-Sahlgren (2017) found no short-term effect of retirement on mental health, but a large negative effect in the longer term. In the United States, Dave, Rashad and Spasojevic (2008) found that complete retirement was associated with a decline in mental health, while noting that the adverse effects were smaller among those who were married, socially supported, physically active or working part-time. These findings suggest that the early lift of freedom can fade if it is not sustained by purpose and connection.

Third, early retirees themselves are frank about the challenges. Brandon Ganch, the Mad Fientist, who stopped working at 34, described the realisation that money no longer motivated him as ‘quite a shocking and uncomfortable shift’, and observed that without something to motivate you, there is little to get you out of bed (Kane, 2017). Tanja Hester, after digging into the research herself, reminded her readers that early retirement ‘is not a magical cure-all’ (Hester, 2018b). Doug of Maturing Well discovered that stress could return through voluntary commitments (Maturing Well, 2019a).

Finally, much of the strongest evidence comes from cohorts of public-sector and utility employees retiring at or around statutory ages, often in the 1990s and 2000s, rather than from people who retire in their thirties or forties. The stories in this chapter help to fill that gap, but they are personal accounts from people with the means to choose their own path. Taken together, the evidence suggests a clear and hopeful conclusion — freely chosen retirement tends to bring rest, relief and renewed wellbeing — with an equally clear condition: that the freedom be filled with meaning, people and a sense of direction.

Putting it into practice

• Make the choice yours. The research consistently finds that voluntary retirement brings the greatest gains. Planning your finances early is, in part, a mental health strategy: it gives you control over when and how you leave.
• Give yourself a decompression period. Many early retirees describe needing weeks or months to unwind. Expect it, and resist the urge to fill every day immediately.
• Protect your sleep. Let your body find its natural rhythm, but keep a broadly regular wake time. If you continue to struggle with sleep after retirement, speak to your GP rather than assuming it will resolve on its own.
• Notice your new baseline. As Tanja Hester found, a calmer mind can be more sensitive to small stresses. Treat that sensitivity as useful information rather than a sign that something is wrong.
• Replace structure, not just time. Work provided routine, identity and social contact. Plan how you will meet each of these needs — through volunteering, learning, creative projects, clubs or part-time work you enjoy.
• Guard against ‘stress creep’. Be selective with new commitments. Saying yes to everything can recreate the pressure you left behind.
• Stay connected. Loneliness is a genuine risk when friends are still working. Build friendships across ages and make regular social plans a fixed point in your week.
• Seek help early if you are struggling. If low mood, anxiety or loss of purpose persist, talk to your GP or, in the UK, refer yourself to NHS Talking Therapies. Retirement is a major life transition, and asking for support is a sign of strength.

Questions for reflection

1. What does your stress ‘baseline’ feel like now — and how would you know if it had changed?
2. How is your sleep during working weeks compared with holidays, and what does that difference tell you?
3. Which parts of your wellbeing currently depend on your job — identity, friendship, routine, a sense of competence — and how might you nourish them elsewhere?
4. If you left work tomorrow, would it feel like a choice or a push? What could you do now to make it more of a choice?
5. What would a healthy ‘decompression’ period look like for you, and how long might you need?
6. Which new commitments would genuinely enrich your life, and which might simply recreate the pressures of work?
7. Who would you turn to if the early lift of freedom began to fade?
