First though, it’s important to know what the cornerstones for sleeping well are. Sophie Bostock, a sleep scientist, explains, that regular exercise, darkness and most importantly: consistency are key. “If you wake up at the same time each day, this anchors your circadian rhythms on the same time zone, making it easier to fall asleep at the same time, and enhancing the depth of sleep.” On top of this, Kirsten says we should consider the temperature of our sleep space and ensure we get as much natural light as possible. “Going outdoors and in bright light in the morning isn’t going to confuse the brain;” in fact he says it helps it know that when it gets dark it’s time to sleep, and when it should be producing more melatonin (the sleep hormone).
