Quality sleep is absolutely integral to our physical and mental wellbeing; however, research for the Sleep Health Foundation in 2016 found that more than 20% of Australians have been diagnosed with significant insomnia. According to this video from TED-Ed, insomnia is caused by a cycle of anxiety and restlessness that prompts a fight or flight response at bedtime, making it impossible to relax, and affecting sleep quality when you finally do nod off. If you suffer from insomnia, the video suggests breaking the cycle by doing activities to manage your stress before bedtime, setting consistent resting and waking times, creating a dark and comfortably cool bedroom, and, if you’re feeling restless at night, leaving your room to do relaxing activities until you feel tired.
