Is it permissible to go swimming while fasting?

Can I go swimming while fasting?

A fasting person can have a bath and swim in a pool or in sea provided that no water enters through his mouth or nose.  (Fatawa al Hindiyya, Beirut 1980, II, 199)  

However, as it is a hardship for the fasting person to avoid swallowing water while swimming, it is more proper to be on the safe side not to put his blessed Ramadan fasting at risk.
