The Surprising Health Benefits of Walking: More Than Just Exercise?

You might not realize this, but a simple brisk 30-minute walk each day can dramatically change how your body functions, enhancing your physical and mental health and even making you feel younger. So today, under the umbrella of "Health Benefits of Walking," let’s delve into the practice of walking, which, in my humble opinion, is the ultimate elixir to a long and healthy life.

Our bodies are evolutionarily hardwired to be active, a trait inherited from our hunter-gatherer ancestors who, based on research, clocked in an amazing average of at least 16,000 steps a day. These consistent, dynamic movements kept them healthy and robust, contributing to the overall wellness of ancient societies. Now, compare that to today's lifestyle: the average American barely scrapes together 5,000 steps. This stark contrast highlights a significant decline in one of the most natural forms of exercise.

 

Now remember, evolution is a slow process, and our bodies haven't quite caught up to our modern, sedentary, tech-driven lifestyle. This disconnect has led to a rise in health issues that our ancestors rarely faced, primarily due to their active way of life.

 

By embracing the health benefits of walking, we can kickstart the journey back to our roots. It's more than just a physical activity; it's a chance to reconnect with the healthy habits hardwired into our biology. From boosting cardiovascular health to improving mental well-being and potentially extending life expectancy, these benefits manifest with each step we take.

So, let's consider walking not just as a mundane activity but as a powerful testament to the simple, effective ways we can enhance our health. After all, if our ancestors thrived on it, why can't we harness its benefits in the modern world? A commitment to walking is a commitment to longevity and vitality, a tribute to the legacy of health left to us by generations long past.

 

My parents who are in their almost 70s walk each day between 7000 - 10,000 steps. They have been doing it ever since they retired.  The best part? I know that its totally anecdotal, but they're enjoying their golden years, free of medication for blood pressure, diabetes, and cholesterol.

 

So here's where the beauty of walking comes into play. This simple exercise affects more than just your physical health; it impacts every aspect of your life, creating a domino effect. You start walking regularly, and before you know it, you're going to feel more energetic, less stressed, and be even in a better mood.

 

Your sleep quality improves, your memory sharpens, and your concentration increases. And all these benefits do accumulate. Ultimately you will be so encouraged by these results that you will want to explore what else you can do to feel even better. It's really addictive but in the best way possible.

 

So you see with just this simple walking you can start transforming your entire life. You see, any physical activity boosts levels of endorphins - those amazing 'feel-good' hormones we all love.

 

But, it also reduces levels of cortisol, which is a stress hormone with lots of damaging effects on our bodies. Some of these include Weight Gain around the abdomen because cortisol can stimulate an increase in appetite as well as blood sugar levels, but it also suppresses the immune system making us more vulnerable to infections and illnesses.

 

High levels of cortisol also contribute to anxiety, depression, and problems with memory and concentration. It will mess up your digestion and raise your blood pressure and cholesterol levels. In women high levels of cortisol interfere with menstrual cycles, reduced libido, and cause fertility problems.

Simple walking can help you reduce all of these damaging effects. But besides that, regular physical activity such as walking has been shown to be one of the very few interventions that is capable of preventing Alzheimer’s disease and other age-associated neurodegenerative disorders.

 

In my last video, I talked about sugar in our diet causing shrinkage of our brain and damage to the hippocampus which is a structure in our brain that is super important for memory and learning. Well, regular walking has been found to prevent damage to the hippocampus and prevent shrinkage of our brains as we age, since it promotes the growth of new neurons in the hippocampus and improves memory function.

 

Now nobody wants to be sick and it happens that walking can greatly support the immune system because it stimulates the production of white blood cells and natural killer cells, both of which play critical roles in the body's defense mechanism. The white blood cells fight disease, while natural killer cells detect and destroy cells in the body that are infected with pathogens or are becoming cancerous.

 

Walking also enhances insulin sensitivity and promotes weight loss. So, for those trying to manage their blood sugar, walking helps your body utilize insulin more effectively which results in better blood sugar levels after meals.

So now you may ask when is the best time to walk and does it really matter when you go for your walk. Well anytime is a good time, but you may want to pick a more specific time based on your goals.

 

For example, walking in the morning can kickstart your metabolism and help you burn more calories throughout the day. It also results in better productivity and mental performance throughout the day. Exercise in the morning has been shown to stimulate brain activity and enhance cognitive function.

 

Now if you're looking for better sleep, morning walks might be literally your ticket to dreamland. They regulate your sleep cycle by reinforcing your body's response to its natural circadian rhythm and as a result, improve sleep quality.

 

If you are trying to control blood sugar spikes after meals, particularly after lunch, walks are a great way to help lower post-meal blood sugar spikes. Even a 10-minute walk after dinner can be more effective at lowering blood sugar than a 30-minute walk at other times.

 

Now what about walking in the afternoon? Some studies suggest that walking in the afternoon or evening might be more beneficial for achieving certain fitness goals. For example, the body's ability to respond to insulin seems to be better in the afternoon and evening than in the morning.

Now let’s talk about where should we walk to get the most benefits of walking. If you have a chance to walk in nature, please do since there are tremendous benefits to it. Research has shown that the color green has a calming and restorative effect.

 

According to color psychology, green is associated with peace, calmness, and relaxation. So, looking at the green color of leaves, grass, and other plants can help your eyes relax and can trigger amazing feelings of tranquility. We have a forest right behind our house and I can tell you that the morning walks there are something that I can’t even describe.

 

As a matter of fact, walking in any natural environment, like parks is increasingly referred to as "forest bathing" or "eco-therapy" because it reduces stress, improves mood, and increases your focus and attention span. There was a study that showed that children with ADHD had much better concentration after just a 20-minute walk in a park.

Now if you find yourself pumped up after a few days of walking and decide to take an even further step forward to making your body feel healthy and strong, I strongly suggest you watch my video on why you should stop eating sugar.

 

If you can combine these two powerful and simple strategies, you won’t believe how amazing you will start feeling in no time.


Back Strain: Accelerate Your Recovery with These Tips

Musculoskeletal Health with Dr D. 

Back Strain: Treatment Guidelines for Back Strain

Most back strains do not require specific treatment, because they usually recover spontaneously in relatively short period of time. There are, however, certain strategies that may help you recover faster and make the process less painful. For full list of detailed recommendations on optimizing your recovery process please follow this link.

Mobility: swimming and walking

One of the most important things to keep in mind, is that during the acute phase, it is of outmost importance to stay mobile. While short term bed rest may help to relieve some of the pain initially, staying in the bed more than 24-48 hrs leads to worse outcomes and prolongs the recovery time.

While becoming more mobile is important, you will need to initially modify your daily routine to avoid high impact activities, lifting heavy objects and twisting movements. The best way start increasing physical activity is walking for few minutes several times a day and eventually transitioning to recreational swimming in a slow pace. Swimming is excellent exercise for recovery from back injuries. It’s weightless nature eliminates gravity and pressure on the spine and takes the muscles and joints through full range of motion. Both activities will keep the muscles engaged without additional strain, and get them slowly ready for more physically demanding exercises.

Heat

Heat plays important role in the treatment of back pain. It improves local blood circulation which enables the injured tissue to heal faster while decreasing muscle stiffness and pain. Applying heat to the painful area after the initial 48 hrs from the onset of the injury also helps with stretching. Additionally, heat reduces pain and makes movement easier when getting out of the bed in the morning. Heating pad should not be applied directly on the skin. While it can be used  several times a day, it should never be applied for longer than 20 minutes at a time. Never sleep on your heating pad!!

Stretching, Massage and Acupuncture

Gentle stretching of the back muscles after using heating pad is important to slowly start elongating the tight muscles. Never push beyond the level of gentle stretch. If stretching is painful, you need to pull back. Gentle massage around the painful area can be very relaxing and soothing. You do not need to spend money on massage therapist, but if you can afford it, this might be a good time to splurge on couple sessions. Getting a simple massage from your partner at least once a day for the first few days can be equally if not more effective. Alternately, you can try self-acupressure using a tennis ball while leaning against the wall and finding the tender spots in your back. Both massage and acupressure help to promote local blood circulation and loosen up the tight muscles which results in increased mobility and less pain. If acupuncture is available to you, getting few treatment sessions can be very helpful to promote relaxation of the tight muscles, increase local blood circulation and decrease pain. For more information about acupuncture please follow this link.

The role of pain medication

While pain medication will not help you to recover faster, they can help to make the process more bearable. Motrin, naproxen or Alleve can be used in mild to moderate pain, to take the edge off the pain. Stronger pain medication, prescribed by your provider, may be necessary when pain is more severe.

 

Goals for pain management

It is very important to understand, that complete pain relief is neither realistic, nor the goal of pain medication or any treatment modality discussed in this article. Pain is a protective mechanism. It makes us start paying attention to our body and prevents us from causing further damage. Additionally, there is no single best remedy. Patience in combination with several treatment strategies placed in the context of a comprehensive treatment protocol, has been shown to lead to the best and fastest recovery.

Spinal Stenosis: Causes, Symptoms and Treatment

Medicine Corner with Dr D 

Spinal Stenosis

Chronic back pain can be a result of spinal stenosis. Spinal stenosis is usually seen in individuals over the age of 50 who developed significant degenerative changes in their spine from wear and tear. The medical word for these degenerative changes is osteoarthritis. Spinal stenosis is a result of the narrowing of the spaces within the spine where the spinal nerve roots are located. When the spaces get too narrow, excessive pressure on the nerves in the area develops.

Symptoms

People affected by spinal stenosis may experience a variety of symptoms. Some individuals may have no symptoms at all, especially in the initial stages, while others may experience significant amount of pain. It is not known why some people experience more or less pain. Spinal stenosis is a degenerative disease and therefore develops slowly over period of time with gradually worsening symptoms. Most individuals experience tingling and numbness in their buttocks, legs, and calves, especially after prolonged walking. Walking up the hill or up the stairs is particularly painful, but even walking down the stairs can lead to significant amount of pain. In more advanced cases, weakness of the legs, pain, and cramping in one or both legs and feet can present with prolonged standing or walking.  In severe cases, an individual may not be able to walk more than few blocks before severe pain develops.

Urination and bowel movement can also be occasionally affected as a result of the pressure on the spinal nerves that control these two essential physiologic functions, and the individual may develop urinary urgency and incontinence. In general, the back pain from spinal stenosis gets better with sitting down for a few minutes. Sitting flexes the spine and this relieves some of the pressure on the nerves. Many individuals with severe spinal stenosis, therefore, walk stoop forward and keeping their torso slightly flexed to lessen the pain while walking.

Causes

There are several reasons why spinal stenosis may develop. The most common causes include osteoarthritis and bone spurs. Osteoarthritis is one of the forms of arthritis. It is a result of wear and tear that affect the protective cartilage on the ends of the bones. When osteoarthritis is present in the spine, it can cause over time narrowing of the spinal canal, which eventually results in spinal stenosis. When bone spurs develop as a result of long term wear and tear, the spurs may grow inside of the spinal canal and cause pressure on the spinal nerves. Less frequent causes of spinal stenosis include a spinal tumor and a car accident. In both of these cases, there are usually several other prominent symptoms that point out to that diagnosis.

Treatment guidelines

In mild cases of spinal stenosis, a conservative treatment approach is recommended. This may consist of physical therapy and strength training, stretching, short term course of acupuncture, daily stretching, swimming, Tai Chi or Yoga exercises. The goal is to keep the back muscle flexible and relaxed as much as possible. Building core strength is also important to properly distribute the weight and decrease the load on the spine. Losing excessive weight is crucial for the successful management of back pain. Carrying less weight translates to less pressure on the lumbar area of the spine from the excessive forward pull of the abdomen.

 

In more severe cases when the benefits of conservative treatment have been maximized, but pain continues to significantly affect the quality of life, surgery may be necessary. This should be however the last resort since there are inherent risks to any surgical procedure. It has been recommended, that only when all other treatment options have been exhausted, and the individual’s quality of life as it is now is poor, surgery should be considered as a possibility to improve current quality of life.
