Here are suggestions from the University of California San Francisco Medical Center on how to prepare for hot flashes, especially at bedtime:

• Keep your bedroom cool, and keep a nearby fan on while you sleep.
  
  
• Wear light, cotton pajamas.
  
  
• Put cotton or "t-shirt" sheets on the bed to help absorb sweat.
  
  
• Have an extra clean pair of pajamas and sheets near the bed, so you can quickly change them if they get too damp.
  
  
• Before heading to bed, take a warm bath or shower.
