New research has shown that women are better sleepers than men.
The study says women take longer to nod off but they wake less often and have a deeper, longer sleep than men.
"We're thinking more, a bit busier, it's potentially why it took them longer to fall asleep because they were a bit more anxious," said Dr Kathleen Maddison, from the University of Western Australia.
Sleep impacts eating habits, mental health, memory and immune system.
Respiratory and Sleep Physician Dr Stuart Jones says Kiwis are getting more tired due to stress and technology.
"I wouldn't be surprised if we've lost a good hour of sleep over the last decade," he said.
So how can you have a better sleep?
Experts say ditch the screens an hour before bed, find time to wind-down like taking a bath, ensure your room isn't too warm and go to bed at a regular time will help.
But the main thing is making sleep a priority.
