1 in 4 Adults Is a Caregiver. Why Are We Surprised They're Angry?
About 63 million Americans gave ongoing care to someone with a serious condition in the past year. That is close to one in four adults, according to the 2025 report from AARP and the National Alliance for Caregiving.
Then we act surprised when some of them get angry.
This is the write-up behind this week's Aging Whealthily Podcast episode. It is general education, not medical advice.
Is it normal for a caregiver to feel angry? Yes. About 63 million Americans, close to one in four adults, gave ongoing care in the past year (AARP and the National Alliance for Caregiving, 2025). In a 2015 Penn State study of 164 dementia caregivers, anger rose and fell with each day's hard events, such as repeated questions, accusations, and refused help with bathing, more than with the stress hormone cortisol. Anger tends to follow the workload. It is not a character flaw. This is general education, not medical advice.
Key takeaways
Close to 1 in 4 U.S. adults is a caregiver (AARP/NAC, 2025).
In the Penn State study, caregiver anger followed the day's hard events. The cortisol link dropped out once those events were counted.
About 49% of the swing in anger happened within the same person from day to day.
In a lab study of young adults kept awake about 35 hours, the brain's alarm center reacted about 60% more strongly. The authors called that finding speculative.
Loving someone and resenting them at the same time is a normal response (Pauline Boss, ambiguous loss).
Original Medicare covers respite care only under hospice.

Why do family caregivers get so angry?
The job nobody applied for. Imagine you hired someone and gave them this job.
No training. No days off. No relief shift. The work starts at 2 in the morning and again at 6. The person they serve may not know their name by spring (more on what dementia really is). There is no pay.
Then imagine being surprised when that worker gets angry.
That is the deal handed to millions of family caregivers. Some of them sit in a Monday meeting. Some of them are making breakfast right now and telling no one about last night.
At Whealthy Nation, we spent weeks in the research on caregiver anger for this episode. We expected a story about stress hormones. We found something more useful.
What does research say causes caregiver anger?
The anger follows the workload. Researchers at Penn State followed 164 family caregivers of people living with dementia for eight days (Leggett, Zarit, and colleagues, 2015). They measured the stress hormone cortisol five times a day and logged what happened each day.
At first, low cortisol days were linked to more anger. Once the researchers counted the hard events of the day, such as repeated questions, accusations, and refusing help with bathing, the hormone link was no longer significant. The events still were.
About half of the swing in anger, 49 percent, was within the same person from one day to the next. Same caregiver. Different Tuesday.
When a strong person starts snapping, look at the day before you look at their character.
One fair limit. Everyone in that study lived with the person they cared for and used adult day services at least twice a week. It describes one kind of caregiver well, not all of them.
Is caregiver anger caused by stress hormones?
The hormone had an alibi. The popular story says cortisol is wrecked, so of course a caregiver snaps.
In that same eight-day study, that looked true at first. Then the day's events went into the model. The hormone link dropped out. The day stayed.
You cannot will a hormone into line. A hard day has parts, and some of those parts can be handed to someone else.
How does lack of sleep affect a caregiver's temper?
Sleep and the brake. There is a brake behind the forehead. It runs on sleep.
In a 2007 study, Seung-Schik Yoo, Matthew Walker, and colleagues kept 26 young adults awake about 35 hours, then showed them upsetting images in a brain scanner. The amygdala, the brain's alarm, fired about 60 percent harder. Its line to the medial prefrontal cortex, the part that can say "she has a disease, don't," went quiet.
Alarm up. Brake off.
The honest guardrails. These were people aged 18 to 30, looking at pictures. Nobody measured anger. The researchers called their own conclusions speculative.
We will not tell a caregiver to "get more sleep." We will say this. When someone gives you three hours, sleep for one of them.
Why can you love and resent the person you care for?
The grief has no bereavement leave. Family therapist Pauline Boss calls it ambiguous loss. The person is physically here and psychologically slipping away. It is a framework, not a lab finding, but it names what many families describe (read stories from people living it).
When a parent dies, people know what to do. There is leave, a card, a casserole. When a parent stops recognizing their own child, there is often nothing. The person is back at their desk at 9.
Boss says that loving someone and resenting them at the same time is a normal response. She also says "closure" is a myth when a situation cannot be resolved. Most caregivers have never been told either one.
Does Medicare pay for respite care for caregivers?
The gap is built into the system. Many people assume Medicare sends someone to give a caregiver a break. Original Medicare covers respite care only as part of hospice, for up to five days at a time, in an approved facility, with a 5 percent coinsurance. Outside hospice, it is not a covered benefit.
So the anger is not a personal failing. It is what tends to follow when one person is handed a job that used to take a village.
How can caregivers manage anger? 4 things to try this week
None of them is "be a better person."
Name the day, not yourself. Next time the anger comes, do not ask "what is wrong with me?" Ask "what happened today?" Count the hard events for one week.
Go after the events, not the feeling. Removing even one hard moment from the day works on what the research points to.
Protect the brake. Use one hour of any break to sleep. (See also small daily habits for brain health.)
Say it out loud to one person. "I love her, and some days I can't stand this." The anger is not proof you stopped loving her. Nobody gets this angry about a stranger.

How can employers support working caregivers?
What a leader can do this quarter.
Say the word "caregiver" out loud. Ask in a staff meeting or a survey who is caring for a parent or spouse. Most will not raise it on their own.
Flex the hard hours. A late start after a rough night, or a protected lunch hour for a doctor call, takes one hard event off the day.
Put one phone number where people can see it: 1-800-272-3900.
Check what the benefits cover. Look at the Employee Assistance Program and the leave policy with a caregiver in mind, not only a new parent.
Drop the word "closure." Do not tell a caregiver to make peace with it. Ask what happened this week.
A flexible schedule does not fix anger. The research does not say that. It says anger tracks hard days. Fewer hard events is the lever with evidence behind it.

Frequently asked questions
Is it normal to feel angry as a caregiver?
Yes. Research on dementia caregivers found anger rises and falls with the day's hard events. It reflects the workload, not a lack of love.
Why do I feel angry at my parent with dementia?
Repeated questions, accusations, and refused help with care were among the daily events linked to caregiver anger in the 2015 Penn State study. The anger usually tracks those events, not the person.
Can you love someone and resent caring for them?
Yes. Family therapist Pauline Boss describes loving and resenting someone at the same time as a normal response to ambiguous loss.
Does lack of sleep make caregivers more irritable?
A 2007 lab study of young adults kept awake about 35 hours found the brain's alarm center reacted about 60% more strongly. It did not study caregivers or measure anger, and the authors called the conclusion speculative.
Does Medicare cover respite care?
Original Medicare covers respite care only as part of hospice, up to five days at a time in an approved facility, with 5% coinsurance. It is not covered outside hospice.
