1. A bed system comprising:
a mattress; and
an air controller configured to draw air from, or supply air toward, the mattress, the air controller including:
a fan assembly configured to cause air to flow;
a humidity sensor configured to detect humidity of air; and
a processor configured to:
receive a temperature setting;
activate the fan assembly based on the temperature setting at a first flowrate;
receive the humidity of air flowing through the air controller;
determine whether the humidity of air exceeds a first threshold value during a first state of sleep; and
based on determining that the humidity of air exceeds the first threshold value during the first state of sleep, adjust operation of the fan assembly to control the fan assembly at a second flowrate that is greater than the first flowrate, control the fan assembly at the second flowrate prior to a second state of sleep that is different than the first state of sleep, and lower the humidity of air below the first threshold value.
