The salt in seawater dehydrates your body. (That's why meat could be preserved with salt.)
The body reaches a very high temperature due to exposure to intense heat and dehydration.

Human cells start to die at 106 Fahrenheit although the body may survive at higher temperatures. Short exposure up to 131 Fahrenheit is possible as long as dehydration is avoided

Not likely. Only a long history of insufflating the powder could potentially cause sufficient inflammation for cancer to even be a possibility. The preservatives are probably more likely induce cancer, but again, only over long-term repeated and significant exposure. Don't fret.
It takes a long time to warm up.
Excessive use of tanning booths as well as prolonged exposure to the sun has been shown to induce premature ageing in peoples skin.

If you do not drink any water at all, of any kind, between 2-4 days, most likely 3. At that point you would die. If you drink seawater, considerably less than that, as seawater is toxic to terrestrial life if ingested in high quantities. If you drank water, you would most likely survive until the water ran out, at which point you would have 3 days before death. However, this is assuming you are not in the water. If you were in the water, you would die of exhaustion and exposure long before you died of thirst.
