The claim that “men 50+ can sleep through the night with an onion drink” is a popular type of wellness headline, but there is no strong scientific evidence that drinking onion water or an onion-based drink reliably cures insomnia or prevents nighttime waking.
Onions do contain nutrients and plant compounds that may support overall health, but they are not a proven sleep treatment.
If someone over 50 is waking often at night, common causes include:
- Needing to urinate at night (nocturia) — sometimes related to prostate enlargement, fluid intake, diabetes, or medications.
- Sleep apnea — especially with loud snoring, gasping, or daytime tiredness.
- Stress, anxiety, or changes in sleep patterns.
- Caffeine or alcohol use, particularly later in the day.
- Pain or medical conditions that interrupt sleep.
Evidence-based habits that may improve sleep include:
- Keeping a consistent sleep and wake schedule.
- Avoiding caffeine late in the day.
- Limiting large amounts of fluid close to bedtime.
- Getting regular daylight exposure and physical activity.
- Creating a cool, dark, quiet sleep environment.
