Dream On! The Importance of Sleep and how to get More. Part One – 10 Key Health Benefits of SleepJun 28, 2021
For many people, 7 hours of restful sleep feels like a dream. And for some, it feels like a waste of time. Because why sleep when there are problems to solve and things to do?
As a health & fitness professional, I think sleep is more important to your overall wellness than how much you exercise. When your body is tired because it hasn’t had a good sleep, a fitness program is simply not achievable. You’ll simply won’t have the energy nor the motivation to do the program or stick to the nutritional plan.
So, when designing your exercise program for this month, have a look at your sleep schedule. Plan out what time you sleep and what time you’ll wake up so that you can reap these key benefits of sleep:
- Weight loss
The Department of Medicine, University of Chicago discovered individuals lost 55% more body fat simply by sleeping 8.5 hours rather than 5.5hours.1
- Reduced Appetite
The hunger hormone ghrelin increased by a 28% for those lacking sleep, and further, they also experienced a 18% decrease in satiety hormone leptin. 2
- Healthy eating
Researchers at UC Berkley found that when you are sleep deprived, the brain area controlling desire has greater control over your decisions than it usually would. Hence high calorie foods become significantly more desirable when sleep deprived. 3
- Staying motivated
A 2016 Sleep Health Foundation Australian Sleep Survey finding that 29% of workplace errors are a direct result of fatigue. 4
- Stressing less
There is a 37% rise in stress hormone cortisol only after one night of inadequate sleep, meaning the next day you’re likely to feel anxious, wired, jittery and unable to switch off. 5
- Improved memory
When you sleep well, your body may be resting but your brain is busy organising and storing memories. So, getting more quality sleep will help you remember and process things better. 6
- Reduced blood pressure
Getting plenty of restful sleep encourages a constant state of relaxation that can help reduce blood pressure and generally keep it under control. 7
- Improved Immunity
While you’re sleeping, your body is producing extra protein molecules that can strengthen your ability to fight infections. 8
- Improved Mood
The better you sleep, the better your ability to stay calm, controlled and reasonable. 9
- Reduced chance of Chronic Disease
Some research studies have shown that not getting enough sleep may lead to type 2 diabetes because of how it affects your body’s ability to process glucose. 10
A regular sleep pattern can also help to lower the levels of stress and inflammation to your cardiovascular system, which in turn can reduce your chances of a heart condition.
