Zendaya suffered heat stroke while filming Dune: Part Two after failing to drink enough water.

In an interview with W Magazine, the star, 28, admitted she purposefully limited her water intake due to the faraway location of the bathroom and her ‘restrictive’ costume that took at least 10 minutes to remove.

Zendaya was filming in Jordan and ended up calling her mother from the bathroom floor, sick.

‘We were in Jordan. It was very H๏τ, and I remember thinking, “Oh, man, the bathrooms are so far away,” because we had to hike to the locations. If you have to pee, you need at least 10 minutes to get out of the costumes,’ Zendaya recalled.

‘I was like, D*mn, I don’t want to drink too much water. I had such a fear of peeing myself or sнιтting myself, honestly, in the suit on set. One day, I didn’t drink enough and I had a heatstroke. I felt so barfy.

‘I remember calling my mom on the bathroom floor, saying, “I feel terrible.” She was like, “Did you drink water today?” I said no. I thought I was being smart, but you can’t do that. So, lesson learned.’

Zendaya’s Dune 2 co-star Austin Butler previously revealed several people fainted from heat stroke in his first week filming the movie.

‘It was 110 degrees and so H๏τ,’ he told Entertainment Weekly. ‘I had the bald cap on, and it was between two soundstages that were just these gray boxes of 200-foot walls and sand.

‘It became like a microwave. There were people pᴀssing out from heatstroke. And that was just my first week.’

The difficult circumstances, however, brought the cast and crew together.

‘It really bonds the entire crew. There’s something so humbling about being in such an uncomfortable environment,’ he said.

Coming into Dune, Zendaya said she was in ‘the best shape’ thanks to her training she had recently undergone for her tennis film Challengers.

‘What was so great is I had been training with the boys on Challengers every day and was in the best shape that I had been in a really long time,’ she told W Magazine. ‘For Dune, the costumes were very heavy and restrictive.

‘The first few weeks, your body’s quite sore. When I was walking through the sand every day, my ʙuтт looked great. So that worked out! I was prepared.’

Zendaya played tennis pro Tashi Donaldson in Challengers, a role that she endured some frustration getting into after struggling to pick up tennis.

However, she soon learned she would not actually be filming with a ball, and ended up shadowing her tennis double to pick up the movements.

‘Midway through training, I remember getting really frustrated. There would be some days where I would feel like, Okay, I’m starting to get the hang of this, and then other days where I couldn’t get a ball over the net.

‘Then I realized we were going to be filming without a ball. Every tennis sequence was thought through and choreographed, so I said, well, maybe I should learn the choreography.

‘That’s something my body has experienced. I started shadowing my very talented tennis double.’

Unfortunately, there was one person she didn’t fool – tennis pro Serena Williams.

‘I thought that may have worked, but it didn’t trick Serena Williams. She was like, “I could tell there were not real balls. But you did all right.”
