Female brains typically reach full maturity in the early-to-mid 20s, while male brains don't fully mature until the mid-to-late 20s, primarily due to differences in prefrontal cortex development.

Teenage 'laziness' is largely explained by biology: adolescent brains undergo major rewiring while their circadian rhythms shift up to 2 hours later, making early mornings genuinely harder for teens than adults.

Chewing gum temporarily improves attention and alertness for about 15-20 minutes after you stop chewing.

While rare, roller coaster rides have been linked to an increased risk of brain injuries, including subdural hematomas (blood clots on the brain's surface) and strokes, primarily due to rapid acceleration, deceleration, and rotational forces.

Brain cells begin to die after just one minute without oxygen. After about 4 to 6 minutes of oxygen deprivation, severe and often irreversible brain damage occurs.

Dehydration is a common but often overlooked cause of daytime fatigue, affecting circulation and oxygen delivery to the brain.

You can't tickle yourself.

The human brain uses approximately 20 watts of power—about the same as a dim light bulb—despite being the most complex organ in the known universe.

Unconsciousness will occur after 8-10 seconds after loss of blood supply to the brain.

The adult human brain weighs about 3 pounds (1,300-1,400 g).

The human brain is insensitive to pain.

Music therapy can help people with brain injuries recover speech, motor skills, and access memories that seemed lost, with some stroke and dementia patients able to sing songs they can no longer speak.

Each nostril processes smells differently, sending signals to opposite brain hemispheres. Some research suggests the right nostril may perceive odors as more pleasant than the left, though studies show inconsistent results.

If you unfolded your brain, it would be about the size of a large pillowcase.

The harder you concentrate on falling asleep, the less likely you are to fall asleep.

You see your nose at all times, your brain just chooses to ignore it.

Studies show that sleeping in a warmer room makes you more likely to have nightmares, while cooler temperatures promote more restful, dreamless sleep.
