There are many benefits from receiving massage. You really need to ask yourself a couple of questions to determine how often to get massages.
'How do you feel?' is a great question before your massage. If you are sick, it might be a better idea to reschedule. If you are stressed, you might want to contact your therapist right now. Another good question is 'do you have any chronic pain?' At this point you should consider what type of massage you need as well. How long has it been since your last massage? More than 6 months? Then, you probably want to start off with something light like a Swedish massage. Every therapist has a different style. If you are currently switching therapist, you may want to schedule frequently using different massage techniques.
Do a little homework and find the perfect fit for your needs. If money isn't a concern, then try to schedule your massage appointments for at least once a week. The release of stress and the long term health benefits will give you a more fulfilling life. There should not be more than 1 month between massages. You wouldn't drive your car more than 5,000 miles without changing the oil. In the same sense, your body needs that same maintenance.
Frequent massages will allow your muscles to soften and become more pliable, which will help with pain, and with stress. Professional athletes like Le'Bron James recognize this. You can stretch your visits out, but that will give your muscles more time to revert back to their old behaviors. All of the years of your life led to your current condition. It will not be eradicated in one session. Speak with a therapist to develop a plan that will best fit your current needs. This will be the best preventative measure to keep the relaxed state of the tissue.
Even if finances are tight, you need to LISTEN TO YOUR BODY. When you start to feel stiff and sore, it may be time for a massage.
