Electronic device providing exercise guide based on exercise capacity and control method thereof

An electronic device comprising:

• memory storing instructions;
• a sensor module;
• a display;
• and
• at least one processor, wherein the instructions cause the electronic device to:
• determine whether a user of the electronic device is in a sleep state using the sensor module,
• repeatedly detect a skin temperature of the user using the sensor module, based on determining that the user is in the sleep state,
• determine whether the user is in a non-sleep state using the sensor module while repeatedly detecting the skin temperature of the user,
• detect the skin temperature of the user using the sensor module, based on determining that the user is in the non-sleep state,
• determine an exercise capacity of the user using a first body temperature of the user and a second body temperature of the user determined based on the skin temperature detected in the sleep state and the skin temperature detected in the non-sleep state, respectively, wherein the exercise capacity is determined by comparing a first reference body temperature stored in the memory with the first body temperature in the sleep state and comparing a second reference body temperature stored in the memory with the second body temperature in the non-sleep state, and
• based on the determined exercise capacity, provide, through the display, an exercise guide including a recommendation message for an exercise strength corresponding to the exercise capacity.
