There are many ways to put your body in balance. Small changes can make a big difference in the way you feel day to day. Though it may take some time, if you make a conscious effort to put your body in balance, you will certainly begin to feel better.
There are a few general things you might need to do to begin putting your body in balance. Some things that can cause you to feel "off" are extra stresses in your life, pressure on the job, and not eating a healthy and balanced diet, getting enough sleep, or exercising. You might also feel that you don't spend enough of your time doing things you want to do, or that you are ignoring an important aspect of your life. All of these things could make you feel imbalanced.
You can begin anywhere, but reducing stress is probably a good place to start. Clearly identify what in your life is making you stressed. If you are working too many hours, see if there is any way you can cut back. If your house or your office is messy, clearing things out, throwing away old items and organizing what you have left is a great way to reduce stress. If you can, avoid bringing work home -- this will help keep your work/life balance in check. If you need to, make a list of things that need to be done and get it off your mind.
Other ways to reduce stress and put your body in balance are to get regular exercise and to eat a healthy diet. If you can make time to work out or go to the gym, that is great. Yoga, Pilates and meditation are great ways to feel more balanced. Even if you only have time to take a short walk on your lunch break or to take the dog for a walk when you get home from work, you will still gain some of the benefits of exercise while taking a break from work. If you can, aim to exercise for 30 minutes to an hour each day. Finally, if you need go as far as creating a schedule and writing in time to exercise and time to relax, it might make a big difference.
Eating a healthy diet is another way to put your body in balance. This means eating mostly fruit, vegetables, whole grains, and lean proteins. Drinking enough water is also important, and some find that avoiding sugars and caffeine is very helpful. Maintaining a healthy weight is important for a healthy, balanced body -- this does not mean you need to be perfectly skinny, just that you should reach a healthy weight for your body type.
