What helps speed up yeast activity?

It has been estimated that a 1°C rise in dough temperature will accelerate yeast activity by about 10 percent. Correspondingly a decrease will cause a similar slowdown of yeast activity. As dough ferments, heat is generated, raising the dough temperature and accelerating the yeast activity.

Does sugar speed up yeast fermentation?

Yeast feeds on sugar so by adding a tablespoon or two provides yeast a readily available food. This increases yeast's activity and speeds up fermentation as well. However, adding a large amount of sugar to your dough will affect yeast's metabolism. Sugar is hygroscopic which means it absorbs moisture from the dough.

Why does my yeast keep dying?

Too much flour in the dough – if it's too dry and heavy, the yeast can't lift it! Not enough kneading – the gluten didn't develop enough to let the yeast lift it. Salt was added to yeast directly or too much salt was added — this can kill the yeast! Try to add salt last, mixed in with the flour.
