The natural environment affects human health. While scientists haven't been able to confirm some kinds of weather effects on health, such as aching joints foretelling a storm's arrival, other weather effects on health are clear.

The most clear are surely the effects of extremely high or low temperatures. If you go out unprotected in extreme cold, you could lose toes or fingers to frostbite or perhaps die of hypothermia.

If you aren't careful while exercising outdoors on a very hot day, heatstroke could kill you.

Many scientific studies indicate that ultraviolet energy in sunlight causes skin cancer and that pollen can aggravate allergies.

But nearly everyone also has a relative or friend who is convinced that his or her joints can do a better job of predicting the weather than any meteorologist could.
