Have you ever slept for eight hours but still woken up feeling tired?
Sleep is not only about how long you spend in bed. Quality also matters—including how easily you fall asleep, whether you wake during the night and how refreshed you feel the next morning.
Most healthy adults generally need around 7–9 hours of sleep each night, although individual needs can vary.
What Affects Sleep Quality?
A restful night usually involves falling asleep without prolonged difficulty, staying asleep for most of the night and waking feeling reasonably refreshed.
Maintaining a fairly consistent sleep–wake routine also matters. This helps explain why reaching eight hours on a sleep tracker does not always mean your sleep has been restorative.
Sleep quality may be influenced by a combination of everyday factors. Stress, work and family responsibilities can make it difficult to mentally wind down, while phones and other screens may increase alertness or delay bedtime when used late in the evening.
Other factors may include:
-
Irregular bedtimes and wake times
-
Caffeine or alcohol later in the day
-
Heavy evening meals or long naps
-
Light, noise or an uncomfortable room temperature
-
Limited daytime activity or exposure to natural daylight
Individual responses vary, so it can be helpful to notice which habits appear to affect your own sleep.
Sleep-Support Ingredients: What the Research Suggests
No single ingredient can guarantee a good night’s sleep. Healthy sleep habits should remain the foundation, although some people may choose to include nutritional ingredients as part of their evening routine.
Tomato extract has been investigated in a small pilot study in relation to several sleep measures. The findings were preliminary, and larger studies are needed before firm conclusions can be drawn.
Tart cherry has also been studied in relation to sleep duration and sleep efficiency. Some studies have reported changes in sleep-related measures, but the overall evidence remains limited and inconsistent.
These ingredients are therefore better described as being researched for nutritional sleep support—not as treatments for insomnia or other sleep disorders.
Everyday Habits That Support Better Sleep
Start with simple, consistent habits that help create more supportive conditions for rest:
-
Maintain a regular routine: Try to keep your bedtime and wake time reasonably consistent, including on weekends.
-
Create time to wind down: Reduce stimulating screen use and choose a relaxing activity before bed.
-
Be mindful of caffeine: Consider limiting coffee, tea and energy drinks later in the day, particularly if you are sensitive to caffeine.
-
Stay active during the day: Regular activity and exposure to natural daylight may help support a healthy daily rhythm.
-
Prepare your sleeping environment: Keep your bedroom as cool, dark, quiet and comfortable as practical.
Small, sustainable changes are often more realistic than trying to create a perfect sleep routine overnight.

Sleep quality is influenced by more than the number of hours you spend in bed. Your daily routine, sleeping environment, activity levels and ability to wind down may all play a role.
Try maintaining consistent sleep and wake times, limiting stimulating activities before bed and creating a comfortable sleeping environment.
Keep a regular routine, make time to wind down and support rest with balanced daily habits.
