You’ve heard it said about having a good head on your shoulders.
But have you ever given any thought to how much the human head weighs?
With the brain, teeth, eyes, muscle and skull, the adult head weighs in at 8 to 12 pounds (3.62 to 5.44 kg).
On average, it’s 10 to 11 pounds (4.5 to 5 kg).
That’s much heavier than most people imagine. It requires a good deal of muscle to keep your head straight.
Think for a moment of holding a 10-pound bowling ball in your hand.
That’s what it’s like for your neck to support your head, especially when tilted forward.
Feel like your head weighs a lot?
Consider the head of a horse.
It weighs around 10 percent of its body weight. This means that a 1,000-pound (453 kg) horse will have a head and neck that weighs 100 pounds (45.3 kg).
~ Fun Fact ~
How much does a human brain weigh? On average, the human brain weighs right around 3 pounds (1.36 kg). How does that compare to other animals? An elephant’s brain comes in at around 12 pounds (5.44 kg), while the heaviest brain belongs to sperm whales. It weighs in at a whopping 17 pounds (7.71 kg)!
