Solitary confinement & isolation: coping in the hole

Even in the smallest space, your mind can keep a room of its own.

By the numbers

How common solitary is, and what research links it with.

How common

122,840+people were estimated to be held in solitary for 22 or more hours a day on any given day in U.S. prisons and jails (Solitary Watch & Unlock the Box, 2023). The authors call this a minimum.
Nearly 20% / 18%of people in U.S. prisons and jails had spent time in restrictive housing in the past year or since arriving (BJS, 2011–12).
10% / 5%of people in prisons and jails had spent 30 days or longer in restrictive housing in that time (BJS).

Mind & health

29% / 22%of people in prisons and jails with current serious psychological distress had spent time in restrictive housing in the past year (BJS).
About halfof people in solitary in one Washington State study had significant signs of depression, anxiety or guilt (AJPH, 2020).
7.3% → 53.3%In New York City jails, 7.3% of admissions included solitary, but those stays accounted for 53.3% of acts of self-harm (AJPH, 2014).
24%more likely to die in the first year after release for people who had spent time in restrictive housing in North Carolina (JAMA Network Open, 2019).

World

15 daysUnder the UN Nelson Mandela Rules, solitary for more than 15 days in a row counts as “prolonged,” which the Rules prohibit.
These numbers show links, not proof that solitary alone caused harm. But they show why care and support matter so much.

What solitary is, and its many names

SHU, seg, the hole: different names, similar experience.

Solitary confinement means being kept alone in a cell for most of the day, with very little contact with other people. The UN Mandela Rules define it as 22 hours or more a day without meaningful human contact.

🏷️ Names you may hearEach facility uses its own words.
Read more
  • Administrative segregation (ad seg)
  • Disciplinary segregation
  • Protective custody, in some places
  • Restrictive housing
  • Special housing unit (SHU)
  • “The hole” or “the box”
❓ Why people are placed thereNot always as punishment.
Read more

People may be placed in solitary for breaking rules, while an incident is investigated, for their own protection, or for health reasons. Some people end up there for long stretches.

Whatever the reason, the isolation can affect the mind in similar ways.

🔁 Lockdowns & isolation by another nameLong lockdowns can feel the same.
Read more

Unit lockdowns, quarantine or being in a cell most of the day for other reasons can bring the same challenges. The coping ideas in this guide can help in all of these.

How isolation affects your mind and body

Normal reactions to a very hard situation.

Humans are built for connection, light, movement and change. When almost all of that is taken away, the brain struggles. What you feel is a normal response to a very abnormal situation.

In a study of people in solitary in Washington State, about half had significant signs of depression, anxiety or guilt. People also described deep loneliness, losing their sense of who they are, and becoming very sensitive to sound and light.

🌫️ Time & thinkingDays blur, focus slips.
Read more
  • Losing track of days
  • Trouble concentrating or remembering
  • Thoughts going in circles
  • Daydreaming much more than usual
🔊 Senses on edgeSmall sounds can feel huge.
Read more

With little to see or hear, the brain can become very sensitive. Doors, footsteps or voices may feel startling or overwhelming.

🌊 Big feelingsAnxiety, anger, sadness, or numbness.
Read more

Feelings can swing quickly, or go flat. Anger can build with nowhere to go. Some people find old memories or trauma coming back.

Having these reactions doesn’t mean you are “losing it.” It means your mind is under heavy strain. Support can help.
🛌 BodySleep, appetite and energy change.
Read more

People often sleep too much or too little, lose appetite, feel stiff or tired, or get headaches. Gentle movement and routine can help.

What research shows

Studies link solitary with higher risks inside and after.

A 2023 count estimated at least 122,840 people in U.S. prisons and jails were held in solitary for 22 hours or more a day on any given day. Many more pass through it over a year.

📈 Self-harm insideA strong link in New York City jails.
Read more

In New York City jails, only 7.3% of admissions included solitary, but those stays accounted for 53.3% of acts of self-harm.

🚪 Risks after releaseHigher risk in the first year home.
Read more

In North Carolina, people who had spent time in restrictive housing were 24% more likely to die in the first year after release, including higher risks of suicide and overdose, than people who had not.

🧩 Who ends up therePeople already struggling are more likely to be placed in solitary.
Read more

BJS found that 29% of people in prison and 22% of people in jail with current serious psychological distress had spent time in restrictive housing in the past year.

⚖️ Links, not proofWhat these studies can and can’t say.
Read more

These studies show strong links, not proof that solitary is the only cause. Researchers say the findings point to the need for alternatives and better care.

International standards: the Mandela Rules

What the UN says about solitary.

The UN Standard Minimum Rules for the Treatment of Prisoners are known as the Nelson Mandela Rules. They were revised and launched in 2015, and they set out how people in prison should be treated around the world.

⏳ The 15-day lineMore than 15 days in a row is “prolonged.”
Read more

The Rules define prolonged solitary as more than 15 days in a row. They prohibit both prolonged and indefinite solitary confinement.

🔚 Only as a last resortFor as short a time as possible.
Read more

The Rules say solitary should be used only in exceptional cases, as a last resort, for as short a time as possible, and with independent review. They also say it should not be used for people with mental or physical disabilities when it would make their condition worse.

💌 Family contactPunishment should not cut off family.
Read more

The Rules say discipline and restrictions should not include a ban on family contact.

🇺🇸 In the U.S.Rules vary by state and facility.
Read more

The Mandela Rules are international guidelines. In the U.S., rules about solitary are set by each state, the federal system and local jails, and they differ a lot. Some places have passed limits; others have not.

This is general information, not legal advice. A lawyer or legal aid office can explain what applies to you. The Legal Services Corporation can help you find free civil legal aid.

Building a day in a small space

Routine gives the mind something to hold on to.

When every day looks the same, a routine you create helps your brain keep track of time and gives you a sense of control. Use meals, count and lights as anchors, and fill the time between with things you choose.

🌅 A sample dayAdjust it to your own schedule.
Read more
  1. Wake: wash, make your bed, a few slow breaths
  2. After breakfast: exercise and stretching
  3. Late morning: read, write or study
  4. After lunch: rest or a mind-travel exercise
  5. Afternoon: letters, drawing or a project
  6. Evening: gentle stretching, prayer or reflection
  7. Before sleep: write one thing you got through today
📅 Keeping track of timeMark each day.
