Do your hands and feet wrinkle in water after death?

Answer 1

I guess once you die, your hands and feet do wrinkle even more if placed in water (after a long time only) because if you die, your skin cells will die quite shortly and thus your hair will die.You stop producing sebum.

Sebum:(thanks wikipedia!)

Sebaceous glands secrete the oily, waxy substance called sebum (Latin, meaning fat or tallow) that is made of fat (lipids), wax, and the debris of dead fat-producing cells.[3] In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands.

Sebum is odorless, but its bacterial breakdown can produce odors. Sebum is the cause of some people experiencing "oily" hair,[4] as in hot weather or if not washed for several days. Earwax is partly composed of sebum. Excessive sebum can be cleansed with detergent (as found in shampoo for oily hair), rather than just using bath soap.[4] Sebum secretion might increase after the first cleansing, so a secondary wash might be needed sooner (such as within half a day). Also, sebum will remain at lower temperatures, when rinsing hair with cold water, so showers should rinse in warm water (as between 37-38ºC, 98-100ºF).[5] Excess sebum has been linked to eating red meats, fried, oily or other foods, but studies are not conclusive.Sebum acts to protect and waterproof hair and skin,[6] and keeps them from becoming dry, brittle and cracked by dehydration. It can also inhibit the growth of some microorganisms (such as some bacteria) on the skin.[6]
