There is a way to increase the amount of stamina that you can use each day. You must collect special berries know as Power Berries. There are a total of 10 Power Berries in Harvest Moon (SNES). You start the game with 100 points of stamina(SP) that can be increased to 200 points of stamina, by collecting all of the Power Berries. Stamina can be replenished by eating food and using the Spa. Here is how you react at certain invertvals of Stamina in the beginning:

100 points (you are fine); 50 points (you start to sweat); 25 points (you start breathing harder; 0 points (you collapse)

Each Power Berry you get increases your stamina by 10 points. This is also applied to the scale shown above.
