According to Professor Gradisar, the key is to pay close attention to your circadian rhythm. “Morning and evening types alike can have their sleep influenced by the timing of their circadian rhythm,” he explains. “The best methods to change the timing of one’s circadian rhythm are to use bright light and/or melatonin at strategic times of the day.”

“As with anything in life, if it’s helpful to define yourself as a morning person or a night owl, then that’s great. If it isn’t, that’s OK too. Some people don’t relate to either, and that’s perfectly fine. Ultimately, it’s about finding a routine that works best for you,” adds Dr Touroni.

Nutrition also plays an important role in the quality and length of our sleep, impacting our early or late waking patterns.

“Some people might feel more energised in the morning, while others get their energy spike during the evening. While others feel a variation of their energy levels throughout the day due to different factors such as stress level, diet, exercise habits or overall lifestyle,” explains Signe Svanfeldt, lead nutritionist at healthy eating app Lifesum.

According to Svanfeldt, there is no right or wrong when it comes to energy levels during the day as long as you don’t feel tired all the time. But if you do feel low on energy, it can be due to lack of sleep, too little physical activity, nutrient deficiencies or that you eat unbalanced or too little.
