The best time of day to exercise, conceive and to learn new things, according to science

Are you having your coffee at the best time of day or going to bed too late? Science might be able to help plan your day to better optimise energy and be more productive

If you’re the kind of person who leaps out of bed and pulls on their exercise gear for a quick HIIT before work, get ready to feel even smugger. Scientists this week announced they might be on the way to finding the ideal time to exercise – and the evidence points to the morning being most effective in terms of fat-burning.

Researchers found that genes involved with breaking down fat and thermogenesis (heat production) were more evident in mice that exercised in the morning — suggesting it had a bigger effect on their metabolic rate. Professor Juleen Zierath, a biologist at the Karolinska Institutet, said: ‘Our results suggest that late-morning exercise could be more effective than late evening exercise in terms of boosting the metabolism and the burning of fat.”

So, what about the best time of day for everything else? While there is no one-size-fits-all answer for every human, scientific research shows that there are optimal times for many of us to do everything from nap to learn a new language. But take note, it’s less about the time on the clock, and when you do things in relation to your wake-up time.
