To exercise, or not to exercise. Being the performer-wanna-be type that I am, I would normally power through it thinking the extra burn could keep me going for a little before crashing early the next night.
If you're a bit fatigued, but got at least 7 hours of sleep, it would make sense to go at it. But experts say the quantity and quality of sleep are more critical to maintaining a healthy lifestyle than regularly exercising. Of course both are necessary and highly desired.
Jenny Evans from Powerhouse Performance says "consistently not getting enough sleep can cancel out the good you’re trying to do by exercising. There’s a strong correlation between lack of sleep and an increase in body fat as well as the consumption of high carbohydrate, low nutrient foods. (Thanks to hormones like leptin and grehlin – which control appetite and satiety – that get all out of whack). No amount of working out can negate poor food choices. Also, a high level of fatigue means your workout is probably not going to be very good."
So the next time everyone's out of the house and I realize my eyelids are still heavy from being sleep deprived, it's back to bed I go.
