Many people suffer from sleep deprivation and poor quality sleep. We have a few pearls to help you on your way to a more restful night of restorative sleep!

Sleep is critical to our mental health, physical health, weight management, disease prevention and our longevity.  It is a cornerstone to overall health in addition to proper nutrition and adequate exercise. Many of us struggle to stay asleep or have restless, unrestorative sleep. 

Consequences of Poor Sleep

1. Decreased ability to concentrate/focus 

2. Decreased physical performance 

3. Decreased productivity 

4. Increased cortisol which can contribute to weight gain 

5. Irritability

6.  Increased risk for chronic health problems such as dementia, high blood pressure, cardiovascular disease and diabetes 

7. Slowed reaction times


We all produce the stress hormone called cortisol . Cortisol is  released from our adrenal glands which can play a large role in our sleep /wake cycles.  In the morning, our cortisol naturally rises and as the day progresses should naturally fall to prepare for bedtime.  Some individuals have the reverse pattern and can't fall asleep at night and are exhausted in the morning. 

When our adrenal glands are not balanced it can affect our stress response, blood sugar levels, body weight and sleep/wake cycles. If our body is in constant psychological /physical stress and cortisol is running high it can affect sleep and blood sugar levels. 


How does stress affect our sleep? We may have psychological stress with family, money or work. We may have physical stress either due to lack of exercise or excessive exercise. Physical stress is also caused from poor diet (processed food/sugars), excessive screen time, environmental toxins and hormonal imbalances. These stressors on the body are all factors that contribute to increased inflammation and cortisol. 

Therefore- it seems that two common factors that could be affecting sleep are cortisol and chronic stress.  If you are waking up at 3am we must look at stress and diet (specifically sugar) as contributing factors due to increased cortisol release!
