Aging and Your Digestive System


by Baxter and Nina

While some people have digestive systems that continue to function well as they age, in a given year, close to 40 percent of older adults experience digestive problems that are caused in large part by age-related changes to their digestive systems! In general, you can optimize your digestive health as you age by staying physically active, reducing chronic stress, supporting healthy eating, and maintaining a healthy weight. So a well-rounded yoga practice, including an active asana practice for exercise, mindfulness practices and meditation to support healthy eating and improve awareness of subtle changes in your body, and stress management practices to reduce the effects of chronic stress and allow you to spend more time in the Rest and Digest state—will support your digestive system overall. 

Now let’s take a closer took at how aging affects the individual components of your digestive system so you can help prevent some of the digestive problems from developing!

Mouth, Tongue, Teeth, and Pharynx. Your mouth gradually changes with age, reducing or changing your sense of taste and altering how you “feel” the texture of food, which can affect your food preferences and eating habits. Chewing may also become more difficult, as your mouth produces less saliva, your tongue works less efficiently to move food, and/or your teeth may wear out. You may also have more trouble swallowing. Although you cannot influence these changes with yoga, mindful yoga practices, such as pranayama and meditation can support healthy eating habits and improve self-awareness, allowing you to tune you into these changes so you can address them with your health care team. 

Esophagus. The smooth muscles lining your entire gastrointestinal tract work less efficiently, slowing the downstream movement of food and liquids. In the esophagus this can cause swallowing, in some cases even gagging, choking, or vomiting. Restorative poses where your head and chest are higher than your belly and standing yoga postures can improve the functioning of your esophagus, and stress management practices will help both you and your esophagus relax.

Stomach. As the lining of your stomach becomes less able to fight damage, your risk of developing peptic ulcers increases. In addition, your stomach becomes less elastic and cannot accommodate as much food, and the stomach empties into the small intestine at a slower rate, which may limit the size of your meals. Using yoga’s stress management practice will support stomach’s functioning, as you reduce chronic stress and spend more time in the Rest and Digest state. 

Small Intestines. Although the movement of contents and the absorption of most nutrients in the small intestines do not change much, they may slow down a bit. However, lactase, one of the enzymes in the small intestine, decreases with age, leading to intolerance of dairy products in many older adults. Cultivating mindfulness may alert you to this change and support better food choices.

Large Intestines. Due to age-related changes in its smooth muscles, waste moves more slowly through your large intestines. This, plus weaker rectal contractions can contribute to constipation, a common problem for older adults. Using your yoga practice for exercise, especially including twists and forward bends, can help support healthy functioning of your large intestines.

Liver, Gallbladder, and Pancreas. As your liver ages, it shrinks, the blood flow in and out is reduced, and repair of liver cells slows, reducing your liver's ability to metabolize many substances. As a result, substances that are toxic to the liver, such as alcohol, can cause more damage in older people than in younger ones, and medication may have a stronger effect or produce more side effects. In the gallbladder, the production and flow of bile decrease with aging, increasing the frequency of gallstones. 
Age-related changes in the pancreas reduces its ability to deal with sugar levels in your bloodstream, contributing to the increased incidence of type 2 diabetes in older people. Overall, to support three these organs, you can use yoga’s stress management tools to spend more time in in the Rest and Digest state and support a healthy lifestyle. To support the work of your pancreas, use your yoga practice for exercise (but you're already doing that for other reasons, right?).

Gut Microbiome.
Older adults have a different microbial profile than younger adults, and, after 65, the number of microbial species decreases and the populations become more similar among individuals. While it is possible these age-related changes might negatively affect the relationship between your gut and your immune system, we don’t yet understand their specific effects. Stay tuned for new research findings! In the meantime, you can use yoga’s stress management tools to support your gut microbiome and foster healthy eating habits.

Enteric Nervous System. Although we still don’t know much about how intestinal nerves age, evidence suggests age-related changes may contribute to the increase in gastrointestinal disorders in older people, such as trouble swallowing, gastrointestinal reflux, and constipation. To support the functioning of your enteric nervous system, use yoga’s stress management tools to reduce chronic stress and spend more time in the Rest and Digest state.

How Yoga Helps Your Immune System


by Nina
Bather Wiping a Wound by Pierre-Auguste Renoir
One of the effective ways you can foster healthy aging is to use yoga to support your immune system. An immune system that is functioning well prevents illness and promotes healing, by fighting off common infections, healing wounds, and scavenging early cancer molecules. You can also use yoga to complement western medical treatments for a wide range of illnesses, including:
  • flu and other common infections
  • rheumatoid arthritis and multiple sclerosis
  • conditions that can affect your immune system indirectly, such as diabetes, heart disease, cancer recovery, and many other
For those with immune system disorders, such as HIV/AIDS and adrenal insufficiency, you can boost immune system functioning while also fostering your physical and emotional wellbeing.

Exercise

Using your active asana practice for exercise promotes your overall health, keeping your body strong and flexible, and by helping your cardiovascular system, digestive system, and respiratory systems to function optimally. By improving your balance and agility, your asana practice prevents injuries that result from falling, and which weaken your immune system.

You can also improve your immune system’s lymphatic circulation with your asana practice. Practicing dynamic poses and flow sequences, where you move in and out of poses with your breath, naturally pumps your muscles, improving the flow of the lymphatic fluids through your body. Although not as effective as moving dynamically, you can even use your static poses to improve lymphatic circulation by rhythmically contracting and relaxing as many muscle groups as possible.

Over exercising can increase inflammation, but gradually introducing appropriate amounts of exercise can be very beneficial, reducing the inflammation and improving overall immune system function. So if you’re suffering from an inflammatory condition, such as rheumatoid arthritis, be carefully to ease gradually into the active asana practice, starting with the most gentle practices.

Stress Management

Because chronic stress weakens your immune system, using yoga’s stress management techniques to keep stress levels in check helps keep your immune system strong. And because your immune system works most efficiently when you’re in Rest and Digest state, spending as much time as possible in state will bolster your immune system, whether you are healthy or ill.

Recent research also indicates yoga’s stress management tools lower stress hormones and other pro-inflammatory molecules in our bodies, so yoga also helps with chronic inflammation, which can be caused by aging. Even newer studies suggest that yoga may turn on beneficial genes in some of our white blood cells, which may ultimately improve our overall immune function. 

Yoga’s stress management tools can also help reduce stress eating and other unhealthy stress-related behaviors that negatively impact the immune system. While we can’t say that any of the stress management techniques are better than others, you may find that one or two work best for you. So, if possible, practice all of them periodically to be familiar with all of them. You can practice any of these stress management techniques as a part of your regular asana practice or alone, at a different time of day.

Better Sleep

To help you stay healthy and keep your immune system functioning optimally, you need a good night’s sleep. Yoga can be really helpful for improving sleep, and we have a whole post on it at 5 Tips for Better Sleep.

Healthy Habits

A healthy diet that provides good nutrition is necessary for a strong immune system, so if you’re struggling with unhealthy eating habits, using yoga to support healthy eating habits will help your immune system function optimally. See Yoga for Healthy Eating for tips about how to use yoga to support healthy eating.

Addiction to unhealthy substances such as cigarettes, drugs, or too much alcohol can weaken your immune system by damaging cells, suppressing immune function and causing inflammation. You can use yoga’s mindfulness techniques to assist in changing harmful habits. It’s beyond the scope of this blog to provide complete information on this, but Yoga Meditation Techniques provides information on how to meditate, which can help improve awareness of thought patterns and strengthen will power.
