How Stress Affects Sleep, Eating Habits, and Mental Health: A Therapist Shares Her Personal Journey

Author: Senior Care Circuit

When we hear the word stress, most of us picture busy schedules, endless to-do lists, work responsibilities, family obligations, and the feeling that there simply aren’t enough hours in the day. For family caregivers, that feeling can become even more familiar. Caring for an aging parent, spouse, family member, or friend can mean balancing appointments, medications, work, household responsibilities, difficult decisions, and the emotional weight that comes with watching someone you love need more support. Somewhere in the middle of taking care of everyone and everything, it’s surprisingly easy to stop paying attention to what is happening within ourselves.

Stress, however, doesn’t exist only in our thoughts. Over time, chronic stress can influence our sleep, eating habits, digestion, mood, energy, relationships, and overall mental health. Sometimes those changes are obvious, but often they’re subtle. A few nights of poor sleep become weeks of exhaustion. Meals become inconsistent because there’s always something else that needs to be done. Patience gets a little shorter, emotions feel a little heavier, and eventually running on empty starts to feel normal.

Because of that, I wanted to have a conversation that wasn’t necessarily about senior care itself, but about the person behind the caregiver. I recently spoke with a Licensed Clinical Social Worker (LCSW) who works with adults navigating anxiety, trauma and burnout. Her approach combines evidenced-based therapy with Eye Movement Desensitization and Reprocessing therapy (EMDR), Ketamine- Assisted Psychotherapy (KAP), and other integrative modalities to help clients move beyond simply managing symptoms and create meaningful, lasting change.

While she spends her professional life helping others navigate their mental health and healing journeys, her perspective is also shaped by something deeply personal: her own experience with and recovery from an eating disorder. Our conversation became much bigger than a discussion about eating disorders. We talked about chronic stress, the nervous system, sleep, nutrition, mental health, family connection, and the importance of allowing ourselves to receive help instead of always being the person giving it.

Sharing Our Stories Can Make Someone Feel Less Alone

Talking publicly about a personal mental health experience isn’t always easy, particularly when you’re also a mental health professional. I wanted to understand what made her comfortable sharing this part of her life and why she felt it was important.

“I realized that the experiences that shaped me could also help other people feel less isolated,” she explained. “And this disease thrives on isolation. I know how powerful it can be to feel someone’s deep empathy of having been in the same situation.”

As a therapist, she is also very conscious of maintaining appropriate boundaries and keeping the focus on the individuals she serves. Sharing her story isn’t about making someone else’s experience about her. Instead, she believes that carefully sharing pieces of our experiences can sometimes open the door for someone else to feel understood. “I also believe that mindfully sharing parts of our own stories can create connection and reduce shame,” she said.

That idea extends well beyond eating disorder recovery. People struggling with caregiver stress, anxiety, grief, depression, burnout, or major life changes can easily begin to feel isolated. We may look around and assume everyone else is handling life beautifully while we’re barely holding things together. Of course, we’re usually comparing our behind-the-scenes reality with everyone else’s highlight reel, which has never exactly been a fair fight.

Sometimes hearing another person say, “I’ve struggled too,” changes something. It doesn’t solve the problem, but it can make the problem feel less lonely.

Chronic Stress Doesn’t Stay in Your Head

One of the things I especially wanted to discuss was the physical impact of stress. We often describe stress as an emotional experience, but anyone who has ever had their heart race before a difficult conversation or felt their shoulders tense during a challenging day already knows that emotions don’t politely remain inside our brains.

“Anything that affects the mind and emotions also affects the body,” she explained. “We are not separate from our bodies from the neck down—our nervous system is constantly responding to what we experience.”

When stress becomes chronic, she explained, the body can remain in a heightened state of alert. Instead of experiencing stress temporarily and then returning to a more relaxed state, the nervous system can continue responding as though something requires our attention. “When stress becomes chronic, the body can remain in a state of heightened alert, leaving a lasting imprint on how we physically feel.”

This is particularly relevant when talking about caregiver stress and caregiver burnout. Caregiving isn’t necessarily stressful every moment of every day, and there can be enormous joy and meaning in caring for someone we love. At the same time, the responsibility can be ongoing. There may always be another appointment to schedule, another decision to make, another phone call to return, or another concern quietly sitting in the back of your mind.

When that happens for weeks, months, or even years, it’s important to remember that caregivers have nervous systems too. Your body doesn’t automatically put its own needs on hold simply because someone you love needs you.

The Connection Between Sleep, Nutrition, and Mental Health

Sleep and eating habits are often among the first things to change when life becomes stressful. They can also be among the easiest things to dismiss. We tell ourselves we’ll catch up on sleep this weekend or eat better once things settle down. Unfortunately, life doesn’t always send an official notification announcing that things have finally settled down.

“It’s virtually impossible to be in a good mood when your stomach is not feeling great or if you’re utterly exhausted,” she said. “When we’re running on empty or our body isn’t getting what it needs, it’s much harder to regulate our emotions, manage stress, and think clearly.”

The relationship between sleep and mental health also works in both directions. When we’re exhausted or haven’t properly nourished ourselves, managing emotions and everyday stress can become more difficult. At the same time, when we’re experiencing anxiety, chronic stress, grief, or other mental health challenges, those feelings can affect our ability to sleep, our appetite, our digestion, and how well we take care of ourselves.

“It’s all connected,” she explained. “Supporting the body is part of supporting the mind.”

It’s such a simple statement, but it’s something caregivers can easily forget. We talk frequently about self-care, but self-care doesn’t have to mean spa days, vacations, or elaborate wellness routines. Sometimes caring for yourself means eating lunch before 4 p.m., getting enough sleep, drinking water, taking a short walk, or admitting that you’re exhausted and need someone else to step in for a little while.

Those things aren’t indulgences. They’re basic human needs.

How Stress Can Change Our Relationship With Food

Because of her personal history with an eating disorder, I also wanted to understand how prolonged stress can influence someone’s relationship with food even when that person doesn’t have an eating disorder.

Her answer shifted the conversation away from food itself. “Many times it is not about the food itself—it’s about the nervous system,” she explained.

Stress can influence appetite and digestion, intensify cravings, or lead people to use food for comfort, distraction, or a sense of control. Other people may have the opposite experience and lose interest in food when they’re overwhelmed. “This is especially true when going through a period of uncertainty,” she said. “Over time, we can become disconnected from our natural hunger and fullness cues.”

That distinction matters because changes in eating habits are often approached with judgment. We ask ourselves why we ate something, why we weren’t hungry, why we’re craving certain foods, or why our routines have suddenly changed. But sometimes a more useful question is simply, “What else is going on with me right now?”

For caregivers, periods of uncertainty can become part of everyday life. A loved one’s health may change. A new diagnosis can arrive unexpectedly. Families may be trying to determine what type of senior care is appropriate or how to divide caregiving responsibilities. Those situations don’t automatically lead to unhealthy eating behaviors, but understanding the connection between stress, appetite, eating habits, and mental health can help us notice changes without immediately criticizing ourselves for them.

Supporting Mental Health as a Family

One of my favorite parts of our conversation was also one of the simplest. When I asked how families can support their mental health in everyday life, she didn’t give me an elaborate wellness routine or a twenty-step plan that nobody has time to follow.

Instead, she talked about connection.

“Families can support each other in everyday simple moments,” she said. “Eat a meal together and have ‘check-ins’ that go further than ‘How are you?’ Go for a walk without your phones and actually talk.”

That last part may be the hardest assignment in the entire article. Put the phone down and walk away. Apparently, we’ll survive.

Her larger point, though, is important. “It’s in the small, consistent habits of connection that make a difference.”

Checking in with someone doesn’t always have to begin with “Are you okay?” Sometimes better conversations start with different questions. Ask what has been weighing on someone’s mind lately, what felt difficult that day, what they’re looking forward to, or what they need more of right now. Those questions invite a different kind of conversation.

For families navigating caregiving together, communication can become especially important. It’s easy for every conversation to become about appointments, medications, schedules, finances, and what needs to happen next. Creating even small spaces where family members can simply be people together—not caregivers, patients, decision-makers, or problem-solvers—can help maintain the relationships underneath all those responsibilities.

Knowing When It’s Time to Ask for Help

Changes in sleep, appetite, eating habits, mood, or energy don’t automatically mean something is seriously wrong. Everyone has stressful weeks and periods when routines aren’t perfect. What matters is paying attention when those changes persist, become more intense, or begin interfering with daily life.

You also don’t have to wait until everything feels unmanageable before talking with a qualified mental health professional or healthcare provider. We often treat asking for help as the last option, something we’re allowed to do only after we’ve exhausted every possible way of handling something ourselves. That mindset can be especially common among caregivers, who become accustomed to being the person everyone else depends on.

But receiving support and providing support aren’t opposites. We can do both.

In fact, one of the most meaningful things she shared came when I asked what she wished someone had told her earlier in her own journey.

“You don’t have to push so hard,” she said. “Let other people in—you do not have to prove that you can handle everything alone.”

Then came perhaps the most relatable part: “You certainly do not have to figure it all out by “x” years old!”

There really is something freeing about that.

We create imaginary deadlines for ourselves throughout life. By a certain age, we’re supposed to have our careers figured out, our relationships figured out, our finances figured out, our families figured out, and apparently ourselves completely figured out too. Then life happens and reminds us that it did not receive a copy of our schedule.

Healing doesn’t follow an arbitrary timeline either.

There Is No Shame in Receiving Help

I ended our conversation by asking what she hoped someone would remember after reading this interview. Her answer brought everything together.

“There is no shame in asking for help or allowing yourself to receive it,” she said. “Sometimes, real change begins when we let go of the need to have all the answers, allow ourselves to be vulnerable, and become open to what’s possible. That willingness to soften and surrender can create space for profound transformation.”

For caregivers, that message is particularly meaningful. When you spend so much of your time caring for someone else, it can become surprisingly difficult to recognize when you need care yourself. You become accustomed to being the organizer, advocate, driver, researcher, decision-maker, emotional support system, and sometimes all of those things before lunch.

But being strong doesn’t mean carrying everything alone.

Mental health is part of overall health, and caregiver mental health deserves attention long before someone reaches complete burnout. Paying attention to changes in sleep, eating habits, mood, energy, and connection can help us recognize when our bodies and minds may be asking for something we’re not giving them.

Sometimes that’s rest. Sometimes it’s a real conversation with someone we love. Sometimes it’s accepting an offer of help instead of automatically saying, “I’m fine.” And sometimes it means reaching out to a professional.

Whatever it looks like, caring for yourself doesn’t mean you’re caring any less about someone else.

It simply means remembering that you’re part of the equation too.
