Grounding, Ocean Swimming, and Sunlight: Natural Ways to Support Heart Health and Cardiac Recovery
Recovering from a cardiac event is about more than medications and workouts—it’s also about restoring balance, lowering stress, and reconnecting with the natural rhythms of the body. Three simple, natural practices can play a powerful role in heart health and recovery: grounding (walking barefoot), swimming in ocean salt water, and getting natural sunlight.
These are the reasons why I love visiting Fort Lauderdale, FL, so I can relax and enjoy the beautiful beach. My favorite place to go is Aruba’s, the only restaurant actuallly on the beach. I can eat a great, healthy meal and then walk outside on the beach (grounding) and then jump in the ocean. All at once!
These habits are especially beneficial on days when flying, when the body experiences increased stress, inflammation, and circulation challenges.
What Is Grounding and Why Is It Good for Heart Health?
Grounding, also known as earthing, involves walking barefoot on natural surfaces such as grass, sand, or soil. Direct contact with the Earth may help neutralize excess electrical charge in the body, supporting relaxation and nervous system balance.
Potential heart-health benefits of grounding include:
-
Reduced stress and cortisol levels
-
Improved sleep quality
-
Enhanced circulation
-
Greater sense of calm and mental clarity
Stress reduction is especially important for individuals recovering from a heart attack or other cardiac event, as chronic stress can negatively affect blood pressure and heart rhythm.
Benefits of Swimming in Ocean Salt Water
Swimming in the ocean is one of the most heart-friendly forms of movement available. Salt water provides natural buoyancy, reducing joint strain while offering gentle resistance that supports cardiovascular fitness.
Why ocean swimming supports cardiac recovery:
-
Encourages healthy circulation
-
Helps relax muscles and reduce inflammation
-
Supports mobility without overloading the heart
-
Promotes nervous system calm and emotional well-being
For those who travel frequently, ocean swimming after flying can be particularly helpful. Long flights often lead to dehydration, stiffness, and sluggish circulation. Salt water swimming helps the body rehydrate, reset, and feel grounded again.
Natural Sunlight and Its Role in Cardiac Recovery
Getting natural sunlight is one of the most overlooked but powerful tools for heart health. Moderate sun exposure supports vitamin D production, which is linked to healthy blood pressure, vascular function, and immune health.
Sunlight benefits for heart recovery include:
-
Supports vitamin D levels
-
Helps regulate circadian rhythm and sleep
-
Improves mood and reduces anxiety
-
Encourages healthier blood pressure regulation
For individuals recovering from a cardiac event, sunlight can enhance energy levels and support the body’s natural healing processes. Even 10–20 minutes of sunlight per day, especially in the morning or late afternoon, can make a meaningful difference.
Why These Practices Work Best Together
Grounding, ocean swimming, and sunlight work synergistically to:
-
Calm the nervous system
-
Improve circulation and oxygen delivery
-
Reduce inflammation and stress
-
Support emotional and physical recovery
These practices remind the body how to heal naturally—without extremes or complicated routines.
Simple, Natural Habits for a Healthier Heart
You don’t need intense workouts or complex protocols to support heart health. Sometimes the most effective recovery tools are the simplest:
-
Walk barefoot on grass or sand
-
Swim gently in the ocean
-
Spend time in natural sunlight
At CIDA Fitness, we believe heart recovery is about rebuilding confidence, strength, and vitality—while honoring the body’s natural design.
If you’re recovering from a cardiac event or working toward better cardiovascular health, these nature-based practices can be powerful additions to your wellness routine.
Look for Aruba’s Restaurant if you visit Fort Lauderdale.

Notes Before You Start
-
Phone camera HRV apps (like Heartify or Welltory) use light changes on your fingertip (photoplethysmography) to estimate beat-to-beat intervals — not as accurate as ECG/chest straps, but great for daily trend tracking.
-
Apple Watch & Samsung Health: Your Apple Watch and Samsung phones/watches do measure HRV passively (especially overnight), but dedicated apps like WatchMyHRV give you more intentional control of readings.
-
External chest straps (Polar, Wahoo, etc.) paired with these apps often give much better HRV quality than camera-only methods.
Bonus Tip
Even if an app is “free,” consistency beats sensor type. Daily 1–3-minute HRV readings done at the same time (like right after waking up) are far more useful than sporadic long tests.

How do you train your HRV?
Great question—HRV (heart rate variability) is trainable, but not in the “grind harder” way most people expect. You improve HRV by teaching your nervous system to shift smoothly between stress and recovery.
Here’s the clean, evidence-backed way to do it.
1. Breathe like you’re training your nervous system (because you are)
This is the fastest lever.
Best method:
-
5–6 breaths per minute
-
Inhale ~4–5 sec, exhale ~5–6 sec
-
5–10 minutes, 1–2× daily
This stimulates the vagus nerve and improves parasympathetic tone → higher HRV.
Tip: Long exhales matter more than big inhales.
2️⃣ Train, but don’t redline all the time
HRV improves when your body learns stress and recovery.
What helps HRV most:
-
Zone 2 cardio (walking, cycling, swimming)
-
Moderate strength training
-
Short, infrequent HIIT (1–2×/week max)
What hurts HRV if overdone:
-
Daily HIIT
-
Chronic “no rest days” mentality
-
Training hard on poor sleep
Think consistent, not crushing.
3️⃣ Sleep is non-negotiable
No hack beats sleep.
HRV-friendly sleep habits:
-
Same bedtime/wake time
-
Cool, dark room
-
No alcohol close to bedtime (big HRV killer)
-
Morning sunlight exposure
Even one poor night can drop HRV for days.
4️⃣ Cold exposure (used correctly)
Short cold stress improves HRV if you recover from it.
-
Cold shower: 30–90 sec
-
Breathe calmly (no gasping)
-
2–4× per week
Avoid long ice baths if already stressed or under-recovered.
5️⃣ Reduce hidden stressors
Your nervous system doesn’t know the difference between:
-
Emotional stress
-
Overtraining
-
Undereating
-
Poor sleep
All lower HRV.
Check:
-
Are you under-fueling carbs?
-
Too much caffeine?
-
Too little downtime?
6️⃣ Eat for nervous system stability
HRV hates blood sugar chaos.
Support HRV with:
-
Adequate carbs (especially for active people)
-
Magnesium-rich foods (or Mg glycinate)
-
Omega-3s
-
Regular meals
7️⃣ Track trends, not daily numbers
HRV fluctuates a lot.
-
Look at 7–14 day averages
-
Morning readings only
-
Compare against sleep, stress, and training load
Low HRV isn’t “bad”—it’s information.
Simple daily HRV routine (10 minutes)
-
5 min slow breathing
-
5–30 min walk
-
Consistent bedtime
Do this for 4–6 weeks and HRV almost always improves.
5 Benefits of Having a Cheat Meal
Heart Rate Variability (HRV): A Helpful Tool for Heart Health Awareness
When it comes to heart health, most people are familiar with resting heart rate and blood pressure.
Another powerful—but often overlooked—metric is Heart Rate Variability (HRV). For individuals living with heart conditions, HRV can be a valuable daily insight into how the body is responding to stress, recovery, exercise, and overall lifestyle habits. Let’s break it down in a simple, encouraging way.
What Is HRV?
Heart Rate Variability (HRV) measures the variation in time between each heartbeat. Even though your heart may feel like it’s beating steadily, the tiny differences between beats tell an important story about your nervous system.
- Higher HRV generally reflects better recovery, adaptability, and nervous system balance
- Lower HRV may indicate stress, fatigue, illness, poor sleep, or overexertion
HRV reflects how well your autonomic nervous system—the system that controls heart rate, breathing, and recovery—is functioning.
Why HRV Is Especially Important for Individuals With Heart Conditions
For people with heart disease, a history of cardiac events, arrhythmias, or those in cardiac rehab, HRV can be a non-invasive way to monitor daily readiness and recovery.
Benefits include:
- Early awareness of stress or fatigue before symptoms appear
- Guidance for exercise intensity, helping avoid overtraining
- Insight into sleep quality and recovery
- Support for long-term heart health habits
HRV is not a diagnostic tool, but when tracked over time, it can help you and your healthcare or fitness professional make more informed decisions.
How to Measure Your HRV
You don’t need medical-grade equipment to begin tracking HRV. Many consumer devices and apps can do this accurately enough for daily awareness.
Common ways to measure HRV:
- Wearable devices (wrist or ring-based)
- Chest heart-rate straps
- Smartphone apps using a short morning reading
For best results:
- Measure once daily, ideally in the morning
- Stay consistent with time and position
- Focus on trends, not single-day numbers
How to Log and Track HRV Daily
Logging your HRV is simple and helps you see patterns over time.
You can:
- Use an app dashboard (automatic logging)
- Track in Apple Health or Google Fit
- Keep a simple journal noting HRV, sleep, exercise, and stress levels
Pairing HRV data with lifestyle notes helps you understand why your HRV changes.
Useful HRV Apps (Including Free Options)
Here are some popular and reliable apps for HRV tracking:
Free or Partially Free Apps
- Elite HRV – Free
- Excellent for beginners
- Uses chest straps or phone camera

A Positive Reminder
HRV is one piece of the wellness puzzle, not a scorecard. Fluctuations are normal. What matters most is
building healthy habits—regular movement, stress management, quality sleep, and proper recovery.
If you have a heart condition, always:
- Discuss new fitness or monitoring tools with your healthcare provider
- Use HRV as a guide, not a source of anxiety
At CIDA Fitness, we believe knowledge empowers healthier choices. HRV can help you listen to your body with confidence, compassion, and consistency.
Why Morning Sunlight Might Be the Health Habit You’re Missing
When people think about improving their health, they often focus on workouts, nutrition, or supplements.
One of the most powerful wellness tools, however, is something you already have access to every day—and it’s completely natural, free, and easy. That tool is natural sunlight, especially first thing in the morning.
The Power of Morning Sunlight
Getting outside shortly after waking—whether for a walk, light jog, cycling, or other gentle cardio—does more than just wake you up. Morning sunlight sends critical signals to your brain and body that help regulate your hormones, energy, and sleep patterns. Even 10–20 minutes of outdoor light exposure can make a meaningful difference.
Sunlight and Dopamine: Fuel for Motivation & Initiative
Morning sunlight plays a key role in regulating dopamine, the neurotransmitter responsible for:
- Motivation
- Focus
- Drive
- Initiative
When dopamine levels are balanced, you’re more likely to:
- Start tasks without procrastinating
- Stay mentally sharp
- Feel energized and purposeful throughout the day
This is why many people notice that a simple morning walk helps them feel clearer, calmer, and more productive—before the day even begins.
Sunlight and Melatonin: Better Sleep Starts in the Morning
Here’s a powerful (and often overlooked) truth:
Good sleep doesn’t start at night—it starts in the morning.
Morning sunlight helps set your internal clock (circadian rhythm), which directly affects melatonin, the hormone responsible for sleep.
Consistent morning sun exposure can:
- Help you fall asleep faster
- Improve sleep depth and quality
- Reduce nighttime awakenings
- Support healthier heart and metabolic function
In short, sunlight early in the day helps your body know when to be alert and when to rest.
Combine Sunlight with Movement for Maximum Benefit
Pairing morning sunlight with light cardio amplifies the benefits:
- Walking
- Easy jogging
- Cycling
- Stretching or mobility work outdoors
This combination supports:
- Cardiovascular health
- Stress reduction
- Hormonal balance
- Mental clarity
And the best part? No gym membership required.
A Perspective from Dr. Jack Kruse
Renowned neurosurgeon and health expert Dr. Jack Kruse, author of Epi-Paleo Rx: The Prescription for Disease Reversal and Optimal Health, emphasizes the foundational role of sunlight in human health:
“Sunlight is not optional for human health. It is a biologic requirement that controls how our mitochondria, hormones, and brain function.”
— Dr. Jack Kruse
This perspective reminds us that modern health often improves when we reconnect with simple, natural rhythms.
Simple, Free, and Accessible to Everyone
Morning sunlight:
- Costs nothing
- Requires no equipment
- Can be done almost anywhere
- Fits into nearly any lifestyle
Whether you’re managing heart health, improving fitness, or simply trying to feel better day to day, this habit is one of the highest-return investments you can make in your well-being.
A Gentle Encouragement
At CIDA Fitness, we believe that sustainable health doesn’t have to be complicated. Small, consistent habits—like stepping outside each morning—can lead to meaningful improvements in energy, focus, sleep, and overall quality of life.
Start tomorrow morning.
Open the door.
Step into the light.
Your body knows what to do.
