Insomnia part 2

My previous newsletter provides practical advice on dealing with insomnia. This newsletter continues the discussion, listing some of the most common causes of insomnia. 

Topping the list: blood sugar:
Waking up during the night and needing to eat to get back to sleep is a sign of low blood sugar. Your brain needs glucose while you sleep, and if levels drop too low, your body will pump out adrenaline and wake you up.

Take a look at your dietary habits. Besides the obvious sugars in snacks, desserts, and drinks, excess sugar can come from milk products, potatoes, wine, fruit, juices, and grains (pasta, rice, bread, etc.). 

Nocturnal urination
Waking up to go to the bathroom is also a blood sugar issue. Nocturnal or frequent urination is one way the body protects itself against the harmful effects of excess glucose. 

Caffeine, excess sodium, and diuretics also cause frequent and nocturnal urination. 


Finally, alcoholic beverages are commonly used to unwind and promote sleep. However, there is a rebound effect during the night as blood alcohol levels drop. This interrupts the structure, duration, and quality of sleep. Consequently, we wake up tired and less alert during the day. 


A good night’s sleep is critical for both short and long term health. Our bodies heal as we sleep, so whether we’re trying to prevent sickness, fight an infection, or recover from an ailment, we need plenty of restful sleep.
