Endocrinologist Warns Five Nights of Poor Sleep Disrupts Glucose

Dr Himika Chawla, senior consultant in endocrinology at PSRI Hospital, warned that getting under five hours of sleep for five consecutive nights impairs blood sugar regulation.

Inadequate sleep reduces insulin sensitivity, allowing more glucose to circulate in the bloodstream after meals while increasing stress and appetite-regulating hormones like cortisol.

Dr Chawla advises adults to maintain consistent bedtimes, balanced diets, and regular physical exercise to support overall metabolic and sleep health.
