Here is a collection of my tips on how to take care of your health - designed specifically for writers (but can be used by anyone who needs an extra reminder that their physical health is as important as what is going on in the brain).
2. Find small ways to move. Getting up to go get more water is a perfect little way to get yourself out of the chair and moving. Take stairs when you can. If there's time, walk to the train rather than the bus on the commute to work or home. Park further away at the supermarket and restaurant parking lots. Stand while on the phone. Anything helps.
If being at the gym is too boring - skip it! You write because you love it and it makes you satisfied. You can find a physical activity that will make you as happy. You will be amazed at how good you feel afterwards and how much more focused and creative you can get!
4. Let your body rest. There are days when your body clearly tells you - stop! You just want to sit down and watch TV or read a book, or even take a nap. Do it. You have to listen to your body or you'll be in trouble.
7. Enjoy your writing time! Yes, for many, writing is also work, but if you forget to enjoy it, it will stress you out. And what happens when you're stressed out? Your health gets affected. And the vicious circle of being tired and sick, and being even more stressed because you can't work, starts.
