Yoga is not just good for your mental health but has also proven to be helpful with musculoskeletal issues, especially lower back pain. It has even shown to provide release from asthma. Yoga is beneficial for everyone but it is especially good for women.

The roots of yoga go back to ancient India, but it has recently been gaining increasing popularity all over the world. Yoga is a Sanskrit word which means ‘union’. It combines physical postures, deep breathing techniques, meditation, and relaxation.

There are many different forms of yoga, including Hatha, Pranayama, Ashtanga Vinyasa, Kundalini, Bikram, etc.

The most popular form of yoga today is the type called Hatha Yoga, which focuses on physical and mental strength building postures. There are many westernized types of Hatha Yoga that are used today to improve overall health and wellbeing.

One variation of Hatha yoga is Iyengar, which focuses on the detail, precision, and alignment of posture and breath control. It helps develop stability, strength, and stamina (R).

Another Hatha variation called Pranayama, also known as breathing exercises teaches you to take deep breaths that are beneficial for your entire body. Pranayama has shown to increase the blood flow and release toxins from your body. Releasing toxins through deep breathing has shown to promote better sleep (R).

Ashtanga Vinyasa Yoga is a practice that involves sequences of yoga postures that are synchronized to breathing. It is more physically demanding than other forms of yoga (R).

On the other hand, Kundalini Yoga includes many meditation techniques. It is mostly used to help with mental control and treating anxiety disorders or meeting mental challenges (R).

Bikram yoga is an intense form that is practiced in a room heated to 105°F with a humidity of 40%. Although it can improve strength and balance in healthy adults, beginners should not immediately try it due to the intense nature (R).

Yoga, the Vagus Nerve, and Heart Rate Variability

The vagus nerve is a part of the autonomic nervous system, and it plays an important role in metabolic homeostasis. Vagus nerve stimulation can be used to help treat or mediate various heart and brain diseases, as well as reduce inflammation (R).

Yoga can stimulate the vagus nerve through the heart and respiration. The cardio-respiratory stimulation of the vagus nerve may be responsible for some of the positive effects yoga has on the brain and emotions (R).

Yoga increases parasympathetic nervous system (PNS) activity by stimulating the vagus nerve. The increased PNS activity then results in an increase of γ-Aminobutyric acid (GABA) levels in the brain (R).

GABA levels are low in patients with mood and anxiety disorders. Since yoga increases GABA, it can lead to greater improvements in mood (R).

Heart rate variability (HRV) is used for health and fitness and is an indicator of autonomic regulation. High HRV is associated with fitness, strength, and resilience to stress.

Yoga can affect HRV in a positive way. Since it affects the vagus nerve, yoga helps enhance heart function, mood, and energy states. All of these effects help increase HRV and keep you healthy (R).

Yoga and Adipokines

Adipocytes (fat cells) and adipose tissue (fat) can accumulate in the bodies of obese patients. Fat tissues release adipose-derived secreted factors, or adipokines, that have either pro-inflammatory or anti-inflammatory activities. Dysregulated secretion of adipokines can cause many diseases (R).

Losing weight can help decrease adipokine levels in the body. Practicing yoga can help you lose weight, which then decreases the amount of fat in your body and protects it from obesity and heart disease (R).

Health Benefits of Yoga

Children and youth suffering from pain or discomfort due to health issues have relief when participating in mind-body yoga (R, R).

Practicing yoga can also reduce inflammation. High TNF-α and IL-6 levels are pro-inflammatory cytokines and can indicate an inflammatory response. Patients that practiced yoga had lower TNF-α and IL-6 levels both before and after exercise (R).

Regular practice can protect against the rise in cytokine levels and protect against inflammation (R).

Yoga increased mindfulness and resilience and decreased PTSD symptoms in soldiers returning from and currently serving in war (R).

Patients suffering from Parkinson’s disease had increased physiological and psychological function after participating in an 8-week yoga program (R).

4) Yoga Reduces Stress

Stress can affect the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS). Physical or psychological stress can trigger the HPA axis, which in turn causes a cascade of physiological, behavioral, and psychological effects. This can lead to depression, heart disease, autoimmune disorders, and more (R).

Yoga includes meditation, relaxation, and exercise. It reduces stress and anxiety and helps control the stress response systems. Yoga reduces heart rate, improves breathing, and lowers blood pressure. All of these effects help control the HPA axis and SNS, thus reducing stress (R).

Yoga practices successfully reduce stress among students who have high workloads and increases their overall perception of joy (R).

5) Yoga Strengthens Muscles and Bones

Learning the proper way to perform yoga poses strengthens your bones and muscles. It increases your flexibility and coordination and all of this can help protect you from the injury.

Yoga also improves balance in male college athletes, which helps them with sports practice (R).

6) Yoga Protects the Heart

As stated earlier, yoga can stimulate the vagus nerve and enhance heart function. It also reduces fat levels in the body, which can help prevent heart disease. Yoga also reduces heart rate, improves breathing, and lowers blood pressure (R).

Total cholesterol levels also lower in adults that practice Bikram yoga (R).

Practicing yoga can also increase blood flow and red blood cell levels in the body. This allows for more oxygen to flow through the blood and helps prevent blood clots. All of these lower the risk of heart attack (R).

7) Yoga Improves Sleep Quality

Yoga can regulate the body’s circadian rhythm, which helps with improving sleep quality. The circadian clock system is synchronized throughout the body and affects physiological and behavioral outputs (sleep, heart rate, etc.) (R).

One thing that helps control the circadian rhythm (known as a behavioral non-photosensitizer) is exercise. Yoga helps alter the circadian activity and improve sleep quality (R).

Yoga can help treat insomnia and sleep difficulties in cancer patients. In a review of different researches and surveys, yoga helped treat insomnia symptoms and reduce tiredness (R).

In one survey of 110 Ashtanga Vinyasa practitioners, 62% of them reported at least one yoga-related injury, which was mainly muscle sprains and strains (R).

In traditional yoga, voluntary vomiting is a common cleansing technique. This technique can cause acid reflux symptoms or dental erosion. However, this style is rarely practiced in North America or Europe (R).

Pranayama, which focuses mainly on breathing techniques, is not appropriate for beginners. There are extreme breathing techniques that resemble hyperventilation which can cause problems in people who do not know how to control their breathing (R).

Bikram yoga is practiced in a room heated to 105°F with a humidity of 40% and is physically intense. The intensity and extreme heat during Bikram make it inappropriate for the elderly and people with medical conditions to practice (R).

Yoga also requires concentration and awareness. It is recommended that practitioners abstain from using drugs or alcohol to avoid adverse events from occurring (R).

Finally, people with high blood pressure, glaucoma, lower back pain, and pregnant women should modify or avoid some yoga poses as they may cause injuries or aggravate some conditions (R).
