WHY GETTING ENOUGH SLEEP IS IMPORTANT IF YOU'RE TRYING TO TONE UP


You have probably been told a million times how important getting enough sleep is. Sleep affects our mood, hormones, hungry, productivity… and well the list goes on. Well we all seem to know sleep is important but do we actually know the impact it has on our body and the impact it has to all that time spent in the gym?
SLEEP PRESERVES YOUR MUSCLE TONE

As published in academic journal, Sleep, stress hormone cortisol increases 37% after just one nights sleep loss—and subsequently, your body is more likely to use your (hard earned) muscles as an energy source. Further, scientists have found deep sleep enhances synthesis of Growth Hormone, fundamental to lean muscle maintenance.
SLEEP REGULATES YOUR HUNGER

Notice how after a sh*t sleep the next day you can’t keep your hands out of the bread basket? Studies show the hormone to increase hunger (ghrelin) rises 18%; whereas leptin, the hormone which tells you to stop eating, decreases by 28%. These researchers also found cravings for sugary carbohydrates increased up to 45%. Any single one of those elements impairs our training results—but together?! Eeeeek.
SLEEP PLAYS WITH YOUR MOOD

With studies showing insomniacs are 9.8% and 17.3% more likely to experience depression and anxiety disorders respectively—sleep clearly directs emotions. Researchers found when we are feeling depressed, we are less likely to exercise and eat healthily, and more likely to smoke, take drugs and binge drink—derailing our good intentions the following day too, when find ourselves knee deep in Netflix and Uber Eats.
