Fortunately for the practice of yoga, western medicine and science have recently taken an interest and have begun thoroughly investigating the practice using randomized controlled studies. This research has shown that even after a short time one can see improvement in the following areas:

• Flexibility- with a gradual loosening in the body, aches and pains start to disappear and proper body alignment and posture are achieved.

• Strength – building strength through yoga balanced with flexibility helps prevent arthritis and back pain and falls in the elderly. It also improves posture, which causes back, neck, and other muscle and joint problems.

• Joint care – yoga takes your joints through a full range of motion bringing necessary nutrients to the cartilage and helping to prevent wearing and damage. This is also true for the spine, helping keep the discs supple.

• Circulatory and Lymph Systems – the practice of yoga lowers cortisol levels. When levels are high, cortisol has been shown to interfere with immune function, increase blood pressure and insulin resistance.

• Emotional Health – studies have found that a consistent yoga practice improved symptoms of depression by increasing serotonin levels.

• Brain and Nerve Center – yoga helps to focus on the present while improving coordination, reaction time and memory. It also encourages you to relax and slow your breath, lowering heart rates and decreasing blood pressure.

• Cancer Patients – yoga reduces fatigue and inflammation while improving sleep quality and lowering stress levels.

• Chronic Pain – practicing yoga has shown to decrease pain and improve function especially for those suffering from low back pain and can be utilized by all age groups.

• Respiratory System – studies have shown improvement in respiratory function in patients suffering from chronic obstructive pulmonary disease.
