Yoga is a practice that connects the body, breath, and mind. It uses physical postures, breathing exercises, and meditation to improve overall health. Yoga was developed as a spiritual practice thousands of years ago. Today, most Westerners who do yoga do it for exercise or to reduce stress.

Yoga can improve your overall fitness level and improve your posture and flexibility. It may also:

• Lower your blood pressure and heart rate
• Help you relax
• Improve your self-confidence
• Reduce stress
• Improve your coordination
• Improve your concentration
• Help you sleep better
• Aid with digestion

In addition, practicing yoga may also help with the following conditions:

• Anxiety
• Back pain
• Depression

Yoga is generally safe for most people. But you may need to avoid some yoga poses or modify poses if you:

• Are pregnant
• Have high blood pressure
• Have glaucoma
• Have sciatica
• Have arthritis

Make sure to tell your yoga instructor if you have any of these conditions or any other health problem or injury. A qualified yoga teacher should be able to help you find poses that are safe for you.

There are many different types or styles of yoga. They range from mild to intense. Some of the more popular styles of yoga are:

• Ashtanga or power yoga. This type of yoga offers a more demanding workout. In these classes, you quickly move from one posture to another.
• Bikram or hot yoga. You do a series of 26 poses in a room heated to 95°F to 100°F (35°C to 37.8°C). The goal is to warm and stretch the muscles, ligaments, and tendons, and to purify the body through sweat.
• Hatha yoga. This is sometimes a general term for yoga. It most often includes both breathing exercises and postures.
• Integral. A gentle type of yoga that may include breathing exercises, chanting, and meditation.
• Iyengar. A style that pays great attention to the precise alignment of the body. You may also hold poses for long periods of time.
• Kundalini. Emphasizes the effects of breath on the postures. The goal is to free energy in the lower body so it can move upward.
• Viniyoga. This style adapts postures to each person's needs and abilities, and coordinates breath and postures.

Look for yoga classes at your local gym, health center, or yoga studio. If you are new to yoga, start with a beginner class. Talk with the instructor before the class and tell them about any injuries or health conditions you may have.

You may want to ask about the instructor's training and experience. However, while most instructors have had some formal training, there is no objective yoga certification body. Choose an instructor you enjoy working with who does not push you in ways you are not comfortable.

Most yoga classes last from 45 to 90 minutes. All styles of yoga include three basic components:

• Breathing. Focusing on your breathing is an important part of yoga. Your teacher may offer instruction on breathing exercises during the class.
• Poses. Yoga poses, or postures, are a series of movements that help boost strength, flexibility, and balance. They range in difficulty from lying flat on the floor to difficult balancing poses.
• Meditation. Yoga classes usually end with a short period of meditation. This quiets the mind and helps you relax.

While yoga is generally safe, you can still get hurt if you do a pose incorrectly or push yourself too far. Here are some tips to stay safe when doing yoga.

• If you have a health condition, talk with your health care provider before starting yoga. Ask if there are any poses you should avoid.
• Start slowly and learn the basics before pushing yourself too far.
• Choose a class that is appropriate for your level. If you are not sure, ask the teacher.
• Do not push yourself beyond your comfort level. If you cannot do a pose, ask your teacher to help you modify it.
• Ask questions if you are not sure how to do a pose.
• Bring along a water bottle and drink plenty of water. This is mostly important in hot yoga.
• Wear clothing that allows you to move freely.
• Listen to your body. If you feel pain or fatigue, stop and rest.
