Believe it or not, humans spend roughly one-third of their lives asleep. No wonder the quality of our sleep is so closely linked to the quality of our lives. Here are some fun facts related to sleep that you might not know about. Let's find out!
How do astronauts sleep?
A person in space goes to bed at night then wakes up the next day. But it's a little different since there is no up or down and no pull of gravity. Astronauts can attach themselves to a wall, a seat or a bed inside the cabin so they don't float around or bump into something.
We're all familiar with songs getting stuck in our heads while we're awake. This phenomenon is called earworms. It turns out that this can happen during sleep as well. Even if we're asleep, our brains continue to process music, which could cause problems in getting to sleep and staying asleep.
Sleep with your pet?
Is it good for you to sleep with a pet? Experts have traditionally said no. Pets, like dogs and cats, do not sleep continuously and they will often get up and walk on the bed. All of the activities will lead to a disturbed sleep. But recent studies found that people with depression or anxiety may benefit from having their pets in the bed.
Socks can help us sleep?
Putting on a pair of socks at bedtime will help you fall asleep 15 minutes earlier and wake up far less. Wearing socks can help a process called distal vasodilation, which refers to an increase of blood to your hands and feet.
A. Can you feel the music clearly?
B. Earworms happen while sleeping?
