This is so important that we gave it a page of its own. But to summarise:
- Eat healthily: Less meat, sugar, caffeine, etc
- Eat often: 6 times a day recommended
- Eat non-sleep-inducing foods at night: anything with L-trytophan
- Consider low-GI foods
Presumably fitness plays a role here too, although I haven't seen any definitive information on it
Polyphasic sleep can create back and neck problems, due to the fact that you're holding them in an upright position for a larger percentage of your time. There are various ways to reduce this:
- Yoga can do this. You may be interested in Sole Goal's Results.
- You may also find that The Egoscue Method of Health Through Motion is good.
It's also much easier to get sick during the transition period. People are divided over whether to quit or soldier on, but you should be aware of it, and try eg. eating Vitamin C and stuff to keep your health up. Someone also recommended that for colds, you should try "try warm-nearly-hot water with a squeeze of lemon juice and a pinch of ground cayenne pepper".
If you thought this page was valuable, please consider returning some of that value by either:
