How To Break The Cycle of Nighttime Wake-Ups, According To Science
Insomniacs may benefit from these two exercises.
Middle-of-the-night awakenings, that frustrating moment when you bolt upright between roughly 2 a.m. and 3 a.m., wide awake despite having gone to bed hours earlier, affect a surprisingly large slice of the population. Research suggests that more than a third of adults experience this interruption in sleep on three or more nights each week.
While occasional nighttime wakefulness can be attributed to a late dinner, a warm bedroom, or simply tossing and turning, a pattern of waking at the same hour night after night often indicates a more persistent sleep disorder: insomnia.
Insomnia isn’t just trouble drifting off; it also shows up as difficulty staying asleep or waking up far too early. Beyond bleary-eyed mornings, it can mean daytime fatigue, irritability, and a growing sense of dread each night as bedtime approaches. Estimates indicate that roughly one in eight Americans has received a chronic insomnia diagnosis at some point, and countless others endure milder but still disruptive sleep struggles.
Over the years, treatments have ranged from relaxation practices like meditation and yoga to prescription sleep aids. But these aren’t always effective or desirable long‑term solutions. A recent study published in the journal Family Medicine and Community Health takes a fresh look at a more straightforward intervention: regular exercise.
Researchers set out to determine not only whether working out helps improve sleep for older adults but also which types of exercise deliver the biggest benefits.
Exercise may help insomniacs find relief from their symptoms.
The investigation pooled data from 24 clinical trials involving just over two thousand participants aged 60 and older. Across these trials, individuals committed to exercising two to three times each week for roughly 50 minutes per session, trying everything from brisk walking and swimming to dance classes, resistance routines, and gentle stretching practices like yoga or Pilates.
After completing their nightly rest, participants rated their sleep quality using a standardized questionnaire designed to capture how quickly they fell asleep, how often they woke up, and how refreshed they felt overall.

After about 14 weeks, results showed that all forms of physical activity improved sleep scores to some degree, but the gains weren’t uniform. Resistance training, exercises focused on building muscle strength, such as push‑ups, squats, and weight lifting, produced the most substantial improvement, equivalent to falling asleep faster and waking less frequently.
Aerobic activities like walking, cycling, and swimming also helped, though their effect was noticeably smaller. Mind‑body exercises such as yoga or Pilates yielded the smallest benefit, though still positive.
Resistance training like push‑ups and weightlifting may improve sleep.
What might explain resistance training’s edge? Strength-building workouts stimulate endorphin release, reduce anxiety, and help regulate body temperature and the body’s internal clock, or circadian rhythm — all key factors in promoting deeper, more restorative sleep.
Moreover, muscle work tends to raise core body temperature temporarily; the subsequent cooldown period afterward aligns with the natural dip in temperature that signals the brain it’s time to drift off.
Based on these findings, adults over 60 looking to curb nighttime awakenings should aim to incorporate muscle‑strengthening exercises twice a week into their routine. That doesn’t require fancy gym equipment - bodyweight moves like lunges, planks, and modified push‑ups count, as do resistance bands or household items used for weight.
Pairing these workouts with moderate aerobic activity on other days can offer further health benefits without overwhelming the schedule.

Regular resistance training doesn’t just target insomnia; it also builds bone density, enhances balance, and supports overall mobility - factors that become increasingly important with age. Importantly, better sleep itself can boost daytime energy levels, sharpen concentration, and improve mood, creating a positive feedback loop that makes it easier to stick with an exercise habit.
For those who have long struggled with nighttime wakefulness, shifting focus from passive sleep aids to active muscle engagement may represent a practical, low-risk strategy worth trying. Even modest twice-weekly sessions of strength work can nudge the body back toward uninterrupted slumber, helping transform frustrating nights into genuinely restorative rest.
