I rarely bring up the idea of meditation to my clients. I'm Buddhist and my particular meditation practices are specific to my Buddhist training. However, the mental and physical benefits of regular meditation can't be ignored, as I know of first hand.
On the mental side, we all know how the nature of our culture right now is a constant buzz saw of information overload, pressure to succeed and stress from personal and/or business lives. We have multiple email addresses, texts, phone calls, twitter, facebook, linkedin... it never ends! Then most of us go home and either get right back on the computer or sit on front of the television. Add to that the extreme noise levels of our cities and the addiction to caffienated and/or sugary drinks many of us have and you have a recipe for information overload on many levels. We need balance to maintain mental calm and happiness in our lives. Basic meditation is a great counter weight to the environmental overload.
On a physical side, many people live in some level of chronic pain. For the most part, our medical establishment goes the route of drugs, either prescription or over the counter. While these may mask the symptoms, they don't remove the cause of the pain. But more than that, many of these drugs have an adverse effect on our sleep, reducing REM sleep. This study looked at the effects of sleep deprivation on pain.
In the study, sleep loss increased sensitivity to pain. If you're taking drugs that are affecting your ability to get full restful sleep, you may be fighting an uphill battle tied to a rock. Anything that can improve your sleep seems to be beneficial to your pain sensitivity. And obviously, a good night's sleep is great for your mental health as well. Meditation gives your mindd enough pause to actually make falling and staying asleep easier.

A basic meditation:

This meditation practice is called "shamatha" in Sanskrit. It is as basic as meditation gets. Sit in a comfortable position, and if your body allows it, on a cushion in a cross legged position is best. Sit with your best, relaxed posture, hands cupped in your lap, right hand resting in the left. Maintain a soft gaze looking just past the tip of your nose (if you want to be all specific, 16 finger thicknesses!). You'll sit and breathe, focusing on the feeling of the air at the tip of your nose. It is really that simple. Your first level goal is to maintain mental and physical quietude for 21 breaths, counting the exhales. As our brains are constantly spewing time lines, deadlines, lyrics to horrible songs, etc, your calm will be constantly interrupted from within. Any time your mind move away from your breath, refocus on your breath and your physical place within the room. If you can continuously think about, and feel your place in the room on the cushion, you'll be able to keep your mind calm and centered. Feel where you are in the room, how far you are from the wall in front of you, from the walls to your sides and from the ceiling. Continue to refocus on your breath and being physically in there here and now. All the while, remaining very still through your body. How often do you just not move? This alone will benefit you greatly. Work up to 21 compete breaths without being distracted by your own internal dialogue and you're there.
Try to take some time to sit every day. The 15 minutes you spend on the cushion can be as big a benefit to your life as any exercise you're doing at the gym. Keep it up!
