A 2-hour nap is generally considered too long for a typical nap, as it often leads to deep sleep, causing grogginess (sleep inertia) and disrupting nighttime sleep; ideal naps are short (10-30 mins) or a full 90-minute cycle, but a 2-hour snooze usually means you've entered deep sleep, making you feel worse, not better.
The same is true of regular napping for long periods. For example, 90-minute daily naps are tied to increased risks for stroke, and two-hour daily naps are associated with an increased risk for dementia.
On the legitimacy of the 8-minute nap, he says “sleeping with your legs elevated can help improve sleep onset and quality as it allows blood to flow more easily throughout the body. This is the sleep science behind the 8-minute Navy Seal nap, but that's not the only thing that makes this nap potentially effective.”
In most cases, two hours of sleep is better than none. Not getting enough sleep will impact your energy levels, focus, mood, and decision-making skills — just to name a few things — so the more sleep you can get, the better.
How to Survive on No Sleep: The Do's and Don'ts
The short answer is no, you cannot survive on 2 hours of sleep a night long term without experiencing serious physical and mental health consequences. While your body might function temporarily, sleep is important for both the short-term and long-term well-being of your brain and body.
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. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
The 3-2-1 bedtime method is a simple sleep hygiene strategy: stop eating 3 hours before bed, stop working 2 hours before bed, and stop using screens (phones, tablets, TVs) 1 hour before sleep, helping your body transition to rest by reducing stimulants and digestive load for better sleep quality. A more detailed version adds 10 hours (no caffeine) and 0 (no snoozing) for a 10-3-2-1-0 rule.
Yes, the 8-minute Navy SEAL nap is a real, popular power-napping technique popularized by former SEAL Jocko Willink, involving elevating your legs above your heart for about 8-10 minutes to achieve quick alertness and energy without grogginess, by improving circulation and promoting relaxation for a fast reset. While not a replacement for full sleep, it's used to combat fatigue during intense schedules.
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.
The 30-60-90 nap rule suggests ideal nap lengths are under 30 minutes for alertness, around 90 minutes for a full sleep cycle, while 30-60 minute naps risk grogginess (sleep inertia) from waking during deep sleep, though some find 30-45 minutes helpful for resetting; the goal is to align your nap with sleep stages, avoiding the disruptive middle ground to get energy without feeling worse.
A prime example is the box breathing technique, famously used by the Navy Seals, known as the 4-4-4-4 method. This simple yet effective method involves a cycle of inhaling for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and then pausing for 4 seconds before the next inhalation.
Own Your 3-Foot Space In Navy SEAL training, there's a simple but profound principle: Own your 3-foot space. It means focusing on what's directly within your control—your actions, your attitude, your effort—no matter how chaotic the environment around you becomes.
Yes, individuals with ADHD are more likely to take naps during the day due to daytime sleepiness. This can impact people of all ages, and because ADHD impairs brain activity regulation, sleep patterns are difficult to form and maintain.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
Starting at 2 months old, if your baby's naps inch past the two-hours mark (more or less), it may be a good idea to wake them for a feeding. While waking a sleeping baby seems like a big no-no, long naps mean less eating during the day, making babies hungrier at night!
The idea is that when your mind tells you you're done and can't go any further, you are only at about 40% of your actual capacity. Push for that extra 60% when your mind is telling you to quit, that you're “at your limit.” Because you're most likely not.
Napping with your legs elevated is a key part of the Navy SEAL nap, and it has several benefits for your overall health. Improved circulation: Keeping your legs elevated promotes better circulation, helping blood return to the heart more efficiently.
The method to fall asleep fast goes as follows:
Our circadian rhythm functions by light and dark cycles and therefore an ideal sleep time is 10pm – 6am give or take ½ an hour either way so a full 8 hours of sleep is achieved each night. Even if you are retired or not working, this is an essential component of good sleeping habits.
In his piece, he revealed that through his years of research, he's found that rumination is the biggest thing that causes poor sleep. He says that being worried about something at night has affected his own ability to fall asleep.
The 80/20 Rule means that you stick to your healthy, consistent sleep schedule 80% of the time. You then can make exceptions to your schedule 20% of the time. The 80/20 Rule allows you to “live life” and enjoy those special moments with your family.
🐌 Did You Know this amazing animal fact? A snail can sleep for up to 3 years! Yes, some snails can hibernate or go into deep sleep to survive harsh weather.
The answer is “probably.” Research has shown that many animals experience a sleep phase similar to humans known as REM (Rapid Eye Movement) sleep, which is closely associated with dreaming. This phase is characterized by increased brain activity and is when most vivid dreams occur.
