Seven Hours May Not Be Enough Without Quality Sleep
Most adults need at least seven hours of sleep, but some need more.
Children and teenagers usually need more sleep than adults.
If you often wake up tired or feel sleepy during the day, you may not be getting enough good-quality rest.
Poor sleep can make it harder to think, remember things, and stay calm.
It can also affect hunger and the body's ability to defend itself.
Being in bed for a long time does not always mean your sleep was restful.
Deep sleep helps the body recover, while REM sleep supports memory and mood.
A regular bedtime and fewer screens late at night may help.
If tiredness keeps happening, talk with a doctor.
Adults are generally advised to get at least seven hours of sleep, but individual needs vary.
Persistent daytime tiredness, yawning, heavy eyelids, and reliance on caffeine can signal insufficient restorative sleep.
Poor sleep may impair concentration, memory, and reaction time, and can affect mood and appetite.
Spending many hours in bed may still leave someone tired if sleep is fragmented or restless.
Consistent bedtimes and fewer late-night screens may help; persistent sleepiness can be discussed with a doctor.
