                 sore throats and headaches; Tan Tock Seng
                 Hospital also saw two cases of heat exhaustion
                 recently

                 SOARING temperatures here are sending more
                 people to the doctor, a Straits Times check with 10
                 clinics and six hospitals showed.

                 Most are not suffering from specific heat ailments like
                 heat stroke or heat exhaustion, said Dr K.M. Tan, a
                 general practitioner.

                 Instead, they have sore throats, caused by a lack of
                 bodily hydration, and headaches triggered by external
                 stimuli like changes in weather.

                 About one-fifth of his patients this month have had
                 such heat-related complaints, he said.

                 Ms Lim Hui Min, a 26-year-old secretary, went to
                 see the doctor yesterday for a severe headache
                 caused by her alternating between her air-conditioned
                 office and the sweltering heat outside.

                 Meanwhile, two cases of heat exhaustion -- with
                 symptoms such as weakness, headaches and
                 dizziness caused by dehydration -- were reported at
                 Tan Tock Seng Hospital over the last two weeks and
                 a minor case of heat rash at Gleneagles Hospital.

                 Hospital officials say they do not see such cases
                 usually.

                 According to the Meteorological Station, May has
                 been warmer than usual, with the mean daily
                 temperature rising above the long-term average of
                 27.5 deg C to 30.5 deg C in mid-May.

                 The change to relatively warmer weather conditions
                 came with the onset of the south-west monsoon
                 season, which is traditionally drier.

                 And, as the first four months of the year were rather
                 wet, the warm weather which followed was an
                 unpleasant surprise for most.

                 And organisations and groups traditionally associated
                 with the outdoors are taking extra care to prevent
                 heat stroke, a potentially fatal condition.

                 The army observes strict heat management and
                 prevention regulations when conducting military
                 training, said Major (Dr) Chiam Tut Fu, head of the
                 Soldier Performance Centre, SAF.

                 The SAF follows a strict hydration regime and adjusts
                 training according to the prevailing climatic conditions.

                 The Basic Military Training Centre even has
                 designated instructors who will remove recruits from
                 training activities if they appear unwell.

                 Various army medical centres islandwide, as well as
                 Singapore General Hospital and Changi General
                 Hospital, are equipped with body cooling units to
                 treat heat casualties.

                 Outward Bound Singapore (OBS) said that although
                 it has not had any cases of heat stroke in the past few
                 weeks, extra precautions have been taken.

                 Said an OBS spokesman: "We now conduct water
                 drinking 'parades' the night before an expedition to
                 ensure that participants hydrate themselves
                 adequately. They also carry extra water supply during
                 expeditions."
 
 

                 KEEP COOL: Protect yourself

                 DRINK at least eight glasses of water a day to avoid
                 dehydration.

                  Eat more fruit with high water content, such as
                 watermelon, to replace water loss from perspiration.

                  Cut down on caffeine and alcohol, which have
                 diuretic properties, meaning that they induce more
                 frequent urination, and thus the risk of dehydration.

                  When exercising in the sun, take a break to slow
                 down and cool off.

                  Exercising in the heat may lead to intermittent
                 muscle cramps, especially in the legs, because of
                 excessive loss of salt and water from profuse
                 sweating.

                  Wear light, comfortable clothing when exercising in
                 hot, humid weather and avoid exposure to the sun
                 from 10 am to 4 pm.

                  Apply sun block before going out, preferably one
                 with a sun protection factor of at least SPF20.
