Effect of a single oral dose of ascorbic acid on body temperature and trace mineral fluxes in healthy men and women. - PubMed - NCBI
Body temperature increased 0.7f for some hours: "Several metabolic changes characteristic of the acute-phase response were examined in healthy men and women following a single 1 g dose of ascorbic acid. Utilizing a placebo-controlled, double-blind protocol, oral body temperatures were recorded in rested, fasted subjects (0900 hr) prior to the consumption of 1 g L-ascorbic acid or placebo (n = 10/group). Temperatures were recorded hourly for the next 8 hours, and again the next morning in the rested, fasted state (0900 hr). Blood samples, collected at 0, 4, and 24 hours post-dose, were analyzed for plasma ascorbate, iron, and zinc. Mean oral body temperature was significantly elevated 2 hours post-dose in the experimental subjects compared to controls (+0.7 degrees F, p = 0.03)."

On tolerance to cold: "Specifically, they administered 200 mg of ascorbic acid daily for 17 days to 20 healthy medical students whose diets furnished about 80 mg of vitamin C daily during the testing period. By measuring the temperature of their skin at room temperature (20°C, 68°F) and 40 minutes after exposure to cold (5°C, 41°F), the authors demonstrated conclusively that skin temperatures in those receiving the vitamin C supplement decreased less after cold exposure than the control group."
On body temperature acclimatization to hot environments: "The authors' analysis also showed that a significant proportion of the vitamin C groups (35 percent) attained an optimal body temperature in three to four days (mean 3.5 days). Only one subject (5 percent) in the placebo group adapted to the heat in a period of four days and some did not achieve acclimatization in ten days."

Personal experience. I started supplementing 4 x 500g time release vitamin C a week ago as a way to help mitigate withdrawals from anti-depressants. One unintentional positive effect has been that my waking temperature has improved by 0.5 F approximately. Previously I would wake up ~ 96.5. This week it's been 97.2. Last meal is 11 hours prior to waking, so the effects are clearly longer than the 2 hours cited in the first study. There's a lot of talk here about raising temperature by almost any means to achieve a new "set point" that the body will adopt as homeostasis after some interval, this also features in the Richfield temperature reset that has been used by some members here.
Perhaps vitamin C is also a valid strategy to do this, at relatively low doses and high safety?
