Navy SEALs can hold their breath underwater for two to three minutes or more. Breath-holding drills are typically used to condition a swimmer or diver and to build confidence when going through high-surf conditions at night, said Brandon Webb, a former Navy SEAL and best-selling author of the book “Among Heroes.”
It requires Marines, clad in cammies and boots, to strip off protective gear, including body armor and a rifle, while in the water under 10 seconds; jump into the pool from a 15-foot tower and swim 25 meters in deep water; employ a floatation device made from a pack; tread water for four minutes, and complete another ...
On missions, they may jump from a plane 11 miles in the air, sit in deadly silence, camouflage themselves in any environment or hold their breath underwater for more than two minutes without releasing a single bubble.
Tom Cruise!" Tom held the previous record, for six minutes, while filming an underwater stunt for Mission: Impossible - Rogue Nation in 2015.
The longest time breath held voluntarily (male) is 24 min 37.36 sec, achieved by Budimir Šobat (Croatia), in Sisak, Croatia, on 27 March 2021.
Yes, there are tough tests in the military that require an underwater swim. Even at SEAL training, where the test is 50 meters without a kick off the first wall plus a forward flip before you start, no one in my BUD/S class failed that test.
All Marines require seven to nine hours of sleep each night—period. Those who insist otherwise should not be celebrated for their toughness; rather, they should be educated and, if neces- sary, marginalized. Sleeplessness should no longer be viewed as macho but rather as foolish and dangerous.
Adult harbor seals can dive as deep as 1500 feet and stay underwater over 30 minutes! To do this, they rely on their amazing oxygen storage capabilities. Harbor seals have a grater volume of blood than other land mammals their size. More blood means more oxygen storage.
Seals are wild animals and will defend themselves if they feel threatened. While they can look harmless, leopard seals can swivel around very quickly from their resting position to attack and can inflict serious injuries to dogs or people.
Prior to diving, phocid (true) seals generally exhale, a behaviour thought to assist with the prevention of decompression sickness.
Seals sleep in the water as well as on land. In the water, they sleep floating in a standing position, like a fishing bobber, or floating horizontally on the surface. Because they are sleeping and not actively swimming, they can stay under water much longer than when hunting for food.
Drop your shoulders and hands.
Relax your neck, your traps; feel yourself sinking into the chair or bed. Then start at the top of your right arm, and slowly relax your biceps, forearms, and hands. Repeat on the other side. And don't forget to keep breathing slowly and deeply.
Relax your face completely – Close your eyes and breathe slowly while relaxing your facial muscles. It's good to start with your forehead and work downwards. Drop your shoulder tension and relax your hands – Once your face is relaxed, work your way down with your neck, and shoulders, and go down one arm at a time.
This military sleep method was used by World War II soldiers to fall asleep within two minutes. Here's how it works: Start by relaxing your entire face, including your foreheads, eyelids, jaw, and tongue. Drop your shoulders and then your hands, letting them fall to either side of your body.

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.”
Cut out caffeine 10 hours before bed. Don't eat or drink alcohol 3 hours before bed. Stop working 2 hours before bed. Get away from your screens 2 hours before bed.
"Relax your eyes, your cheeks, your jaw and focus on your breathing. Now go down to your neck and your shoulders. "Make sure your shoulders are not tensed up. Drop them as low as you can and keep your arms loose by your side, including your hands and fingers."
Close your mouth and quietly inhale through your nose to a mental count of four. Hold your breath for a count of seven. Exhale through your mouth, making a whoosh sound for a count of eight. Repeat the process three more times for a total of four breath cycles.
Getting That Morning Wake-Up Call
In military basic training, there's no such thing as sleeping in. You'll get up at 5 a.m. every single day. Waking up in the morning is an adjustment process that's the same for every single basic training class.
Most Soldiers report sleeping 6 to 7 hours per night, regardless of duty status. However, nearly 1 in 3 report getting less than 6 hours of sleep on weeknights/duty nights. Soldiers also report getting more sleep on weekend/non-duty nights than on weeknights/duty nights.
Some aspects of seal behaviour can make us think they are injured when they are not. For example, did you know that seals secrete a watery substance from their eyes when on land? This is often perceived as the seal crying or mistaken for an injury, when in fact it is a natural mechanism to protect their eyes.
A recent UCLA study published in Bioacoustics discovered that 65 animal species have their own form of “laughter.” Among the species who make such playful vocalizations are seals, dogs, rats, and mongooses.
