Cause and effect

In plain English

Among adults with prediabetes and insufficient sleep, adding sleep extension to lifestyle changes leads to larger reductions in daytime sleepiness than lifestyle changes alone.

See the scientific wording

In adults with prediabetes and short sleep duration, both lifestyle intervention alone and lifestyle intervention plus sleep extension lead to significant improvements in daytime sleepiness, but the addition of sleep extension results in significantly greater reductions in sleepiness compared to lifestyle intervention alone.

Why this might work

When a person sleeps less than needed, their brain accumulates sleep-inducing chemicals that make them feel tired during the day. Adding more sleep clears these chemicals faster and resets the body’s internal clock, making them more alert in daylight. Lifestyle changes help a little, but more sleep clears the tiredness even more.

    People with prediabetes who slept too little felt less sleepy during the day after eating better and exercising, but those who also tried to sleep longer and at better times felt even less sleepy than those who only changed their diet and exercise.
