Can sleeping late cause diabetes?
Can diabetes cause sleep disorder?
The answer to above both questions is “YES”.
Both are interrelated and depend on other factors.
Lets refer below case
Peter is 42 years working professional. He is obese with Type-2 diabetes.
He is diagnosed with polyuria. Many times, he suffers from numbness in hands and limbs in morning.
He generally is dehydrated, feels tired and takes nap at daytime in office.
Just like Peter lot of people with type-2 diabetes are found to be suffering from
- Higher usage of sleep medications,
- Poor sleep quality,
- Excessive daytime sleepiness.
Just like Peter Diabetic patients suffering from hyperglycemia may have elevated blood sugar levels at night.
This leads to kidney trying to excrete the excess glucose leading to more urination.
Need of frequent visits to bathroom in middle of night not only disturbs sleep but also leads to tiredness causing need of sleep during daytime.
This sleep disturbance may lead to physical complications like peripheral neuropathy and polyuria.
Polyuria is when your body makes excessive pee (urine).
A normal adult makes about 3 litre urine per day but people with polyuria make about 12-15 litre urine per day.
Peter may be suffering from Peripheral neuropathy. It is damage to nerves located outside of brain and spinal cord. This may cause numbness to limbs and hands.
Just like Peter in obese people body tends to draw water from tissues causing de-hydration.
It has also been published that people having erratic sleeping habits along with sleep curtailment as part of lifestyle choices may have higher blood sugar levels due to irregular dietary habits.
What is interrelation between sleep patterns and diabetes?
In recently published article in Experimental Physiology by Wiley presented interrelations between sleep patterns and diabetes .
It was reported that people who tend to get up early in morning may have reduce prevalence of Cardio-vascular disease along with C-reactive proteins and low triglycerides and High density lipo-protein (HDL).
It was found that people who tend to get up early in morning show more metabolic flexibility compared to people who get up late.
Metabolic flexibility is ability of individual body to choose source of energy in resting and wake up state.
It is known that in healthy individuals blood sugar or carbohydrate is main source of energy during moderate to high intensity exercise compared to fat utilization..
Though gymnasium trainers give preference to fat oxidation while designing programs in gymnasium to increase fat consumption i.e fat oxidation during gym exercises.
It is also found that in insulin resistant individuals like prediabetes and diabetic individuals’ body have reduced glycogen utilization (blood sugar) and higher fat consumption i.e fat oxidation during exercise as compared to healthy individuals.
It is also reported that healthy individuals tend to be insulin sensitive and insulin stimulates carbohydrate utilization in them. This shows their metabolic flexibility.
Further it was also put forth that people who wake up early in morning tend to rely on fat utilization i.e fat oxidation for energy needs during rest and switch to blood carbohydrate or sugar utilization during moderate or high intensity exercise.
Early waking people are active throughout day leading to more blood sugar/carbohydrate burning in daily activities and fat burning at rest as compared to people who wake up late.
What are normal hours of sleep?
According to research paper published by National library of Medicine people sleeping less than 6 hours and more than 8 hours may have elevated blood sugar levels.
What are benefits of sleep?
- Neuron maturation: important process in neurogenesis, leading to neurons gaining their electrophysiological, morphological, and molecular characteristics.
- Facilitates learning and memory development.
- Erases unimportant information which is daily collected and may clutter synaptic network.
- Cognition: Development of knowledge and understanding in mind.
- Conserves metabolic energy
- Clearance of metabolic waste generated when brain is awake.
