Our brains are constantly exposed to different sounds and smells.
We are exposed to many different stimuli daily, so how does our brain respond to them? Is it possible to wake up from sleep if you hear loud noises or smell strong smells?
During wakefulness, your brain produces alpha, beta, and gamma waves. Conversely, theta and delta brain waves dominate during sleep. Delta and theta waves are more powerful when sleeping, so your brain can respond to noise.
During sleep, however, your brain does not lose alpha-beta power necessary to understand and memorize sound. That’s why although sounds can wake you up from sleep, you cannot remember things you’ve heard during your sleep.
While sleeping, scents stimulate beta and gamma brainwaves, which predominate while awake. Consequently, you cannot wake up from sleep when you smell an odor while sleeping.
