OK, I'm not a doctor, so here's what info I found for you that'll be better than what I can tell you:
Causes of Getting Hot
* Certain medicines, including thyroid hormone, morphine, drugs to reduce fevers, and medicines to treat mental disorders
* Emotional or stressful situations (anxiety)
* Low blood sugar
* Overactive thyroid gland
* Spicy foods (known as "gustatory sweating")
* Warm temperatures
* Withdrawal from alcohol or narcotic pain killers
After sweating, you should:
* Wash the face and body
* Change clothes and bed sheets
* Drink plenty of water to replace lost body fluids
* Slightly lower room temperature to prevent more sweating
When to Contact a Medical Professional
* You sweat a lot or if sweating lasts for a long time or can't be explained.
* Sweating occurs with or is followed by chest pain or pressure.
* Sweating is accompanied by weight loss or most often occurs during sleep.
