HIITs and Blood Pressure

When it comes to lowering blood pressure exercise is a non-negotiable factor.

You may be thinking, "what is the most effective form of exercise to lower blood pressure?"

More and more studies are showing the exciting results of something called HIIT in lowering blood pressure. HIIT stands for High Intensity Interval Training

What is HIIT?
HIIT is not any specific exercise, rather, it is a technique. You can apply this technique to almost any kind of exercise whether it be walking, riding a bike, swimming, doing some body weight exercises or even dancing in your living room.

** ALWAYS CHECK WITH YOUR PHYSICIAN BEFORE STARTING ANY FORM OF EXERCISE FOR HIGH BLOOD PRESSURE

HIIT training consists of combining very short bursts of working at your absolute max alternating short periods of active recovery rest. Research has found that this form of exercising gives you more health benefits than any other way of exercising.

It shortens the amount of time you need to spend on exercise and is more effective; you work out for just 10-30 minutes and reap impressive health benefits. You burn more body fat, your metabolism is stimulated for long after you finish exercising, and it also it helps you utilize oxygen more efficiently.

One of the biggest benefits people find from HIIT is the reduction in training time. Through HIIT, you can put in about half the amount of time compared to traditional cardio exercise to reach your goals.

One study found that just 2 minutes of HIIT sprinting increased metabolism as much as 30 minutes of running. HIIT increases the efficiency of your heart and HIIT training also has a major effect on naturally lowering your blood pressure.

HIIT and blood pressure:

Although most any type of exercise has its benefits, HIIT shines when it comes to saving time. Using the HIIT technique is the ultimate short-cut. 

Study after study shows that HIIT exercise improves blood pressure in people with hypertension better than any other kind of exercise routine.

HIIT is extremely effective in reducing resting heart rate and blood pressure in overweight and obese individuals. 

It has been shown that HIIT exercising just 3 times per week for just 20 minutes at a time lowers blood pressure more effectively than continuous endurance training.

What is the science that makes HIIT so effective?

HIIT training changes something called endothelial function

The endothelium is a very thin membrane that lines the inside of your heart and your blood vessels. The cells in this membrane release a variety of substances that control how your blood vessels relax and contract.

We know that stiff hard arteries play a role in high blood pressure.

The ability of your artery walls to expand (vasodilate) is very important.

You need to have flexibility in your arteries to allow for appropriate blood flow throughout your body.

HIIT improves endothelial function and reduces the stiffness in your artery walls more so than any other traditional form or exercise.

Just a 1% improvement in your endothelial function can result in a 13% reduction in the risk of cardiovascular events like heart attacks and strokes.

One study showed that 73% of people restored blood pressure to normal using a HIIT training method for just 2 months and 24 exercise sessions. There was a significant reduction in systolic blood pressure from 145.4 (± 9.0) to 118.3 ( ± 15.6) mm Hg.

How to Apply HIIT

With HIIT training you're are going to go ‘all out' at a high intensity for short amounts of time. You then do an ‘active recovery' rest for a short interval. You can apply this technique to any kind of exercise, walking, running, jumping rope, cycling and even to weight training.

I personally prefer using a stationary bike for minimizing injury. It is simply a great option to implement HIIT into your workouts.

Using the HIIT on a stationary bike

Warm-up for 5 minutes on a low setting.

After your 5 minute warm-up increase the tension on the bike and pedal as fast as you can for 20 seconds. This is called the Sprint phase. After the 20 second sprint phase, lower the tension on the bike and comfortably pedal for 2 minutes.

This is one session of HIIT.

Repeat the above 5 times and you are done.

Heart Recovery Tip

After doing your 20 second sprint, lower the tension and wait 60 seconds and check your pulse. You want your elevated pulse to come down between 8-10 beats. This is your heart recovery zone. If for some reason your pulse does not come down 8-10 beats you should stop and call it a day. For example: After you do your all out sprint for 20 minutes your heart rate when go up to 110 beats. After one minute of decreasing the tension and comfortably pedaling, your heart rate should come down to 100-102 beats. That is a good heart recovery.

Although as I mentioned above I prefer the stationary bike this can be applied to walking as well. Simply walking at a comfortable pace for 5 minutes then do an all out "brisk" walk for 20 seconds. Walking comfortably for 2 minutes then repeat five times.

That is all you need to do to maximize this effective form of exercise (HIIT) to lower your blood pressure.

HIIT can be powerful—but only when it’s done right for your body. Schedule your free Health Discovery Session and let’s make sure your workouts are actually helping, not hurting.

What you should know about heavy metal detox if you have an autoimmune disease.

When it comes to autoimmune conditions, many of my clients are eager to find answers about the foods that could be triggering their symptoms. They often think, "If I just avoid certain foods, I’ll feel better." But, what they might not realize is that food combinations can play a huge role in causing autoimmune flare-ups, even when the individual ingredients don’t show antibodies on their own. It’s a tricky and often frustrating area of functional medicine, but understanding it is key to healing. Here's what you need to know. Understanding Food Protein Reactions Let’s start with the basics. In a perfect world, food sensitivities and allergies are pretty straightforward. You eat a food, your body reacts, and you know exactly what caused the problem. Unfortunately, with autoimmune disease, the story is more complex. As a functional medicine practitioner trained under Dr. Datis Kharrazian, I don’t just look at individual foods—I look at immune response. And food proteins can behave very differently when combined. You may have a test that shows no antibodies for specific foods, think chicken, potatoes, or broccoli. But when those foods are cooked together in a meal, something changes. The proteins in those foods could combine in a way that causes your immune system to recognize them as a threat, triggering an autoimmune flare-up. The reason for this is cross-reactivity, where similar amino acid sequences in different food proteins can cause your immune system to confuse one food for another. This phenomenon is real, and it's something I see often in my practice. Just because a food doesn’t show a reaction on its own doesn’t mean it won’t cause issues when combined with others. The Role of Cross-Reactivity Cross-reactivity happens when your immune system mistakes one protein for another because they share a similar amino acid sequence. For example, if you react to salmon, you might also react to other types of fish due to similarities in their protein structures. This concept is why combining foods like certain grains, dairy, and legumes might trigger reactions in some individuals, even if they’ve tested negative for antibodies to those foods. Let’s look at a real-world example. Imagine eating a gluten-free Kung Pao chicken that’s free of contamination. You’d think that meal would be perfectly fine, right? But if that combination of chicken, spices, and vegetables triggers a reaction, it could be because of how the proteins in those foods interact once combined. Why You Should Pay Attention to Food Combinations In the context of autoimmune disease, where your immune system is already overactive, food reactions can be subtle and unpredictable. So, the next time you’re tempted to dismiss a food intolerance because a test didn’t flag it, think again. It’s not just about the individual foods—it’s about how they interact in your body. You need to pay close attention to how different food combinations make you feel. It’s easy to get caught up in thinking that food sensitivities only apply to the big culprits: gluten, dairy, or soy. But as an autoimmune patient, it’s essential to understand that your body might be reacting to the interaction of multiple foods. So while a test might show that chicken and broccoli are “safe” on their own, eating them together in a casserole could trigger symptoms. The N=1 Approach to Autoimmunity and Food Sensitivities Here’s the bottom line: There is no one-size-fits-all approach when it comes to food and autoimmunity. As I always tell my clients, you are the expert on your own body. Testing can give us a great starting point, but it’s your unique experience that helps us narrow in on what’s truly causing your flare-ups. This is why food sensitivity testing—while helpful—is just one part of the puzzle. You have to be keenly aware of your body’s reactions and the foods you’re combining, even if the individual ingredients test negative for antibodies. Don’t ignore what your body is telling you. If something doesn’t feel right after a meal, listen to it, and make adjustments accordingly. The Takeaway If you're struggling with autoimmune symptoms and haven't been paying attention to food combinations, it’s time to start. While food testing is an invaluable tool, it doesn’t give us the full picture. You may need to do some trial and error with food combinations to uncover what’s really triggering your symptoms. It’s also important to remember that autoimmune healing is complex and individualized. You are an N=1, which means your treatment plan should be tailored to you. Don’t be afraid to advocate for your health, and work with a functional medicine practitioner who can help guide you through the nuances of food reactions and autoimmune management.

For many of us, our experience with food comes with some sort of baggage. Maybe you eat to cope with stress, anxiety or depression. Maybe you’ve grown up with value-words placed on food such as “junk” and “healthy,” and told you couldn’t eat the “good stuff” (brownies and ice cream) until you finished the “yucky stuff” (broccoli and lettuce). Or, even more serious, maybe you or a loved one has struggled or is struggling with an eating disorder. Food is amazing and life-giving. It can be used as a means to celebrate, socialize, or simply just provide fuel for the body. Our relationship with food shouldn’t be a difficult one, it should be an enjoyable one. A way to get to that healthy place in your relationship is to practice mindful eating. Mindfulness is a Buddhist concept of mediation that can help you recognize emotions and physical sensations present. Through mindful eating, you can learn to truly pay attention to your experiences, cravings and physical cues. The basics of mindful eating are: Eat slowly, without distraction. If you are eating with others, take a least five minutes at the start of the meal to enjoy the food on your plate before engaging in discussion. Pay attention to your body--are you still hungry, or are you getting full? Learn to distinguish between cravings and true hunger. Use all your senses when you sit down to a meal. Make an effort to notice how the food looks, smells, tastes, feels in your mouth, and sounds when you chew. Appreciate your food, who has prepared it (even if it’s you--what an accomplishment!), and where it comes from.  Being mindful of your experience will help you slow down while eating. This can prevent overindulgence by making the act of eating intentional instead of automatic. It will also help you become aware of triggers that make you want to eat (are you truly hungry at 9pm every night when you sit down to watch that Netflix show, or do you just pour yourself a bowl of Chex Mix because that’s what you always do?). Knowing your triggers can give you time to process what’s truly going on and the ability to react properly.
