It's better to get 3 hours of sleep than no sleep, as any amount of rest helps, but 3 hours is still significantly short of the 7+ hours most adults need, leading to impaired function; however, aim to get more sleep later, as 3 hours allows for a few sleep cycles, potentially reducing grogginess compared to a full night of no sleep, but don't overrate your abilities in that state.
In conclusion, while three hours of sleep is not ideal, it is generally better to choose sleep over staying awake. Even a short period of sleep can provide some benefits for your mental function and overall well-being.
Ideally? No. Only getting three hours of sleep in a day can leave you sleep-deprived, which has been linked to various negative outcomes8 for emotional, cognitive, and physical health. These can include a weakened immune system, an increased risk of obesity, memory decline, and more.
So no, having your eyes closed in bed does not count as sleep, but it's not like it's not beneficial either. Quiet wakefulness is an intermediary step for all of us to get to sleep on a healthy schedule, unless we are accustomed to being so exhausted we fall asleep within seconds of laying down.
Bottom line: One extra hour of sleep is usually worth it when you're sleep‐deprived and can afford some wake-up recovery time; when immediate alertness is required, prefer shorter naps or a full ~90‐minute sleep cycle to minimize grogginess.
Sleeping beyond the minimum 90-minute cycle may mean you fall deeper into your sleep cycle and will find it much harder to wake up. The best answer to this question is that some sleep is always better than none. Trying to get in a power nap or achieving that full 90-minute cycle is better for you than no sleep at all.
The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion.

Yes, the Navy SEAL sleep trick (an 8-minute power nap with elevated legs) is a real technique for quick rest, popularized by former SEAL Jocko Willink, that helps improve alertness and reduce fatigue, though its effectiveness depends on individual relaxation skills and it's not a substitute for full nighttime sleep. The method involves lying down, elevating your feet above your heart (on a chair or couch), relaxing facial muscles, dropping shoulders, and clearing your mind for about 8-10 minutes to promote relaxation and blood flow, preventing grogginess.
