Experts recommend limiting your use of a hot tub or sauna during pregnancy to less than 10 minutes at a time, or forgoing them altogether, especially in the early weeks. Sitting in a hot tub or sauna can raise your body temperature to a level that can be dangerous for your developing baby. Studies have shown an increased risk for neural tube defects in babies of women who had an elevated temperature before 7 weeks of pregnancy.
By the International Ice Patrol (IIP) Q. How large was the iceberg that sank the RMS TITANIC? A. The exact size of the iceberg will probably never be known but, according to early newspaper reports the height and length of the iceberg was approximated at 50 to 100 feet high and 200 to 400 feet long.
In the Northern Hemisphere, the largest iceberg on record was encountered in 1882 near Baffin Island. It was 13 km long, 6 km wide, and was about 20 m above water. It weighed over 9 billion tonnes - enough for everyone in the world to drink a litre of water a day for more than 4 years. Icebergs from Antarctica can be many times larger. In 1987 an iceberg, with an area of 6,350 sq. km, calved from the Ross Ice Shelf.
