HOT CABIN; TURBULENCE AND INEFFECTIVE CABIN ATTENDANT REST SCHEDULE RESULT IN FATIGUE.

Narrative

WHEN CREW BOARDED THE ENTIRE ACFT WAS WARM BUT THE BACK OF THE ACFT WAS OVER 90 DEGS AND THE BUNK ROOM WAS 109 DEGS. THE DAY WAS IN THE MID 70'S BUT THE ACFT SITS IN THE HOT SUN ON THE REMOTE WITH NO COOLING FOR HRS. NONE OF THE WINDOW SHADES HAD BEEN SHUT OR THE VENTS OPENED FOR COOLING OF THE ACFT. THIS FLT DEPARTS AT XA45. HOT ACFT HAVE BEEN A CONSISTENT ISSUE IN ZZZZ. A HOT ACFT DEFEATS EVERYTHING THAT I DO AS A FLT ATTENDANT TO COMBAT FATIGUE. MY BODY IS USING UP ALL ITS RESERVE FUEL TO KEEP MY BODY COOL THUS THE EFFECTS OF FATIGUE HIT EARLY. THIS IS A 13 1/2 HR DUTY DAY AND STARTING IT OFF WITH A HOT ACFT IS UNSAFE AND UNHEALTHY. ACFT AT DOOR 5 STAYED AT 90 DEGS FOR OVER AN HR INTO THE FLT. AGAIN THERE WERE 3 BREAKS ON THIS FLT AND ALTHOUGH IT WAS A DAY FLT THE HOT ACFT THAT WE BOARDED ALONG WITH THE TURB THAT WE ENCOUNTERED DURING ALL 3 BREAKS HINDERED THE ABILITY FOR CREW TO GET SUFFICIENT REST. WITHOUT SUFFICIENT REST THE CREW IS PUT AT RISK FOR FATIGUE. AFTER THIS TRIP I TOOK A 5 HR NAP AT HOME AND STILL WAS ABLE TO SLEEP THROUGH THE ENTIRE NIGHT. I HAVE NEVER SLEPT THAT MUCH AFTER A TRIP AND CONTRIBUTED IT TO THE LACK OF REST CREATED BY 3 BREAKS AND THE HOT CABIN.
