They don't call it "fan death," but I was surprised to read this in the Times today:
| Quote: |
The authors of the new report pointed out that when temperatures climb past 95 degrees, having a fan pointed at you can actually contribute to heat gain, not reduce it.
At those temperatures, being directly in the path of hot air blown from a fan can raise the risk of dehydration and heat exhaustion.
The researchers said that while they could not support or recommend against the use of electric fans in sweltering conditions, it was important to consider their potential harms and benefits. |

| Whether or not a fan cools you depends upon the humidity in the air. If the air is substantially dry then a fan that is blowing hot 95 degree air will cool you. Your body temperature is 98.6 F or 37 C, higher than 95 degrees. Your sweat contains a lot of heat and the fan will cause the sweat to be absorbed in the atmosphere thus heat being taken from your body. If the humidity is high enough though you have to take into account the convective transfer of heat from the hot air flowing against your body to your body vs. not enogh heat being lost from your body to compensate because the air won't absorb the sweat your producing. Bangkok humidity with a 95 degree temperature I would wonder if the article is right. Who knows? |

| O'Connor paraphrases the authors, "being directly in the path of hot air blown from a fan can raise the risk of dehydration and heat exhaustion." But he cuts off the rest of their statement. The authors continued, "...if these fluids and electrolytes are not replaced quickly enough." In other words, DRINK PLENTY OF WATER and mix in a little orange juice and salt for electrolyte replacement. |

But obviously, if you are sleeping, that's not going to happen.
Anyway, it's all beside the point. Basically, my theory is that poor, elderly people don't have enough money for air conditioning, so will have a fan instead. On hot summer days, they are naturally susceptible to heat stroke, so when their family finds the body, the poor little fan is chugging away and gets the blame. |
