Diabetes is a fast
increasing lifestyle metabolic disorder. Adequate sleep is important for proper
functioning of the body. The rampant deprivation of sleep can lead to a slew of
Human sleep occurs in the form of circadian cycle.
A circadian rhythm implies to a 24-hours physiological cycle that
determines the sleep and waking pattern of living beings.
Diabetes type 2
affects the normal sleep-wake cycle however not much is known about the
exact mechanism causing it.
Tomoko Nakanishi et al
conducted a study to analyze the bedtime, waking time and average estimated
sleep in non-type 2 diabetic and type 2 diabetic individuals. The study was
published in the journal of Diabetology and Metabolic Syndrome 2012.
106 respondents were
categorized in two groups: non-type 2 diabetics (32) and type 2 diabetics (74).
Questionnaire comprising of various questions on sleep status and lifestyle
related diseases was given to them and results were analyzed.
It was discovered that on weekdays the type 2 diabetic
respondents went to bed later than the non-type2 diabetics. Type 2 diabetic
patients also woke up relatively later than the non-diabetics on weekdays and
holidays. However no considerable differences were noticed in the sleep
duration in the two groups of respondents. Type 2 diabetics were reported
to sleep more than the non-diabetics in daytime.
The study concluded that the irregularities of sleep-wake
cycle are common in type 2 diabetic individuals in contrast to non- type 2
diabetics. Further research is required to confirm the role of such sleep
abnormalities in type2 diabetes mellitus patients.
