Narrative:

After departing ZZZ I was the pilot monitoring on climb the flaps were retracted before appropriate speed. After noticing I told the captain and he lowered to nose about 5 degrees and the plane accelerated normally.we had come from ZZZ1 with a show time of XA10. This flight had no crew meals. We landed in ZZZ and had 1 1/2 hrs till this flight. Neither the captain or myself could get anything to eat because nothing was open in the terminal. We were both hungry and hot. On taxi out we both made the comment how hot the plane was and the covid mask didn't help that. There were several airplanes taking off with similar call signs and it was busy. I personally felt a little task saturated after takeoff. The captain called for flaps up right at radio call and frequency change. I never looked up and retracted the flaps.I feel that I should have been offered at least a snack. The airplanes should have the APU left on in the ZZZ heat. I find the covid mask to be a distraction. Somehow we need to address similar call signs. Turn the autopilot on as soon as possible at busy airports.

Title: Air carrier flight crew reported retracting the flaps during climb before the appropriate airspeed and stated that fatigue; hunger; and excessive heat in the aircraft contributed to the event; and the COVID-19 mask was a distraction.
