What happens to your eyes if you are in the dark for a long period of time and then exposed to light?

Nothing dangerous: Eyes adapt to both light and dark fairly easily. In the dark, the pupils dilate to allow in whatever light there might be, and the retina's dark-seeing receptors (rods) are capturing the images you see. Once you enter the light, the pupils constrict rapidly and forcefully which may cause temporary discomfort. You may also find things excessively bright, but there is no danger in healthy eyes. ...Read more

A lot of eye motion for a long period of time makes me dizzy and sometimes vertigo even on car rides if it turns alot quickly movements what to do?

Get evaluated: Some dizziness can be brought on by discoordination at the ear/eye/balance centers of the body and can respond to some simple forms of treatment such as anti-dizziness medications, exercises to restore head balance, and allergy treatments.

Can defecation after death be prevented if a person went a long period of time without food or water before death?

Can defecation after death be prevented if a person went a long period of time without food or water before death?

Not necessarily: One cannot control sphincters after death -- and there can be seepage as a result. Bacteria are still active even without food. I wonder why you're asking this though? Are you considering harming yourself? If so, I hope you'll tell your parents, your doctor or therapist about it so they can help you. Also you can call 911 or go to an er before carrying out any such thoughts. Be well. ...Read more

They also found out that it’s not only the smoke from that burning joint that caused these problems, but also the inhalable form of the active ingredient delta-9-tetrahydrocannabinol dropped testosterone. ...Read more
