October marks Breast Cancer Awareness Month, a time to pause and reflect on prevention, resilience, and hope. While screenings, treatments, and medical breakthroughs are crucial in cancer prevention and management, there’s another powerful tool we sometimes overlook: self-care. Far from being the luxury it can appear on social media, self-care is a science-backed strategy that strengthens our body’s defenses, helps regulate blood sugar, reduces inflammation, and reduces risk of cancer progression/regression.
In times of stress or uncertainty, whether it’s a new diagnosis or simply the upheaval that the holiday months can bring, prioritizing self-care often feels difficult, yet this is exactly when it matters most. Research shows that daily self-care habits—how we eat, move, sleep, and manage stress—can have profound effects on chronic conditions like diabetes and cancer. The beauty of self-care is the almost endless list of strategies that can work depending on the individual. Let’s explore how self-care works at the biological level and discuss some practical strategies that you can choose to protect your health.
Self-Care for Chronic Condition Management
Self-care is not just bubble baths and spa days – it’s anything you do in your day to day life to manage chronic stress within your body. Studies repeatedly confirm the benefits of a variety of self-case strategies for minimizing inflammation and maximizing stress resilience. A recent study in the Journal of Clinical Endocrinology & Metabolism showed that lifestyle changes, especially in diet and exercise, significantly improved blood sugar control for people with prediabetes. Even more striking, these same lifestyle interventions lowered the risk of developing cancer. Another study published in Cancer Research highlighted how chronic stress fuels cancer progression through biological mechanisms such as hormone release, inflammation, and impaired immune function. The authors emphasized that managing stress is not just about emotional relief—it may actually help slow or prevent cancer growth.
Stress is more than the feeling you get when you’re running late and there’s traffic—it’s a cascade of biological changes that ripple through the body. When stress is chronic, your adrenal glands release elevated levels of cortisol and adrenaline. These hormones raise blood sugar, impair insulin sensitivity, and keep your body in a constant state of “fight or flight.” Over time this damages immune function and fuels inflammation, both key drivers in diabetes, metabolic syndrome and cancer progression. Simple strategies such as deep breathing, meditation, progressive muscle relaxation, or even short mindfulness breaks can quickly lower cortisol levels and help combat this chronic inflammatory process. Just five minutes of slow, intentional breathing can help reset your nervous system from “fight or flight” to “rest and digest.”
Evidence-Based Self-Care Strategies
We have lots of resources on both nutrition and fitness throughout our blog posts so we will focus this particular section on more active stress-resilient strategies that have been studied to have true effects on health outcomes.
Sleep Hygiene
Sleep is your body’s time for repair and reset. Deep, restorative sleep helps regulate blood sugar, restore immune balance, and clear out cellular waste through the glymphatic system in the brain.
Lack of sleep, on the other hand, raises cortisol, increases appetite hormones, and weakens immunity. To support sleep:
- Dim lights in the evening.
- Power down screens at least an hour before bed.
- Keep your bedroom cool, dark, and quiet.

Social Connection
Self-care is easier when your environment encourages it. Social connection is a powerful stress buffer and strong relationships reduce stress reactivity, improve immune function, and increase adherence to healthy behaviors. This is why support groups, wellness workshops, and group exercise programs are so effective—they combine accountability with connection. Outside of group activities, any social connection is beneficial – phone a friend, go in person to the grocery store rather than a delivery, bring your lunch to the local park for a picnic and say hello to those who walk by. Isolation is the number one cause of decline as we age so make it a point to bring social connections into your daily life.
Breathwork
Breathing strategies stand out as the most effective of all self-care strategies, which may be due to its incredible accessibility. Breathwork is free to everyone and available at any time as long as you know how to practice it. You don’t need equipment, a gym, or even much time—just your lungs and a few minutes of focus. Endless research studies show the following significant benefits of consistent targeted breathwork:
- Improved perceived stress and cortisol: Slow, deep breathing activates the parasympathetic nervous system, shifting the body out of “fight or flight.” Clinical studies have shown that controlled breathing can reduce cortisol levels within minutes, lowering overall stress load.
- Blood sugar regulation: Elevated stress hormones like cortisol raise blood sugar. By reducing cortisol through breathing practices, people with diabetes or prediabetes may see improved glucose stability. A 2021 study in Frontiers in Public Health reported that slow-paced breathing improved fasting glucose and insulin sensitivity in adults with type 2 diabetes.
- Inflammation and immunity: Breath work practices have been linked to reductions in systemic inflammation markers (such as CRP). By calming the stress response, breathing may indirectly support immune function and lower inflammation that drives chronic disease.
- Cancer care: For cancer patients and survivors, research suggests that daily breathing or mindfulness-based breath practices improve quality of life, reduce anxiety, and may enhance treatment tolerance.
You don’t need to meditate for hours to get these benefits—just a few minutes can make a big difference if practiced often throughout your week. Here are two simple techniques that we like a lot:
- Box Breathing (4-4-4-4 method): Inhale for 4 counts, hold for 4 counts, exhale for 4 counts, hold for 4 counts. Repeat for 2–5 rounds. This method is great for when you are preparing for a stressful event, or before meals or bed to tell your nervous system your safe and calm.
- Extended Exhale Breathing: Inhale slowly through the nose for 4 counts, then exhale for 6–8 counts. The longer exhale calms the nervous system and promotes relaxation. This method is a favorite when you find yourself in an acute stressful situation and know you need to calm down fast. Or simply practice it while waiting in line at the grocery store!
If the idea of overhauling your lifestyle feels overwhelming, start small and start with self-care techniques that feel good. Massage, facials and spa days are a great start to show your body how good relaxation can feel. But we encourage you to also build strategies into your daily life so that self-case isn’t a once-a-month experience. Choose one practice—perhaps a daily walk, five minutes of deep breathing, or swapping soda for water—and build from there. Consistency, not perfection, is what creates lasting resilience.
