All of this doesn’t mean doing a session just before bed though. Haven’t you ever experienced post-training energy that makes it impossible to sleep? It all comes down to your blood pressure, according to Dr Ramlakhan.

“Naturally, your blood pressure should lower by up to 20% at night time. However, immediately after a workout your blood pressure can rise, which makes it hard to wind down. Exercising early in the day, on the other hand, helps to lower the levels of the stress hormones – adrenaline, noradrenaline, and cortisol – which then has an anti-hypertensive (blood pressure lowering) effect,” explains Dr Ramlakhan.

“The production of endorphins during and post-exercise also produces a feel-good factor which can have the additional effect of lowering blood pressure to help us sleep.”

And let’s not forget that the sleep-exercise relationship works both ways: the magic from your workout actually happens when you sleep, as it’s during the night that muscles recover and rebuild stronger. In fact, studies show that a lack of sleep actually results in muscle loss.

Excuse us, we’re off to snooze.
