Recently, the temperature has increased. For 18 counties and cities, the Central Weather Bureau issued excessive temperature warnings on July 7^th. Even in the afternoon, Taipei reached a temperature of 38°. Dr. Ooi Hean, an expert in critical care, made the observation that, under high temperatures, many individuals may have been subjected to heat damage one after another before they experience heat stroke, leading to several antecedents of heat stroke, such as heat edema, heat rash, heat cramp, and heat syncope.

Heat Edema:

In attempt to remove extra heat from the body and prevent overheating, the body dilates blood vessels when exposed to a hot environment. This causes a lot of blood to collect in the ankles, resulting in local ankle edema.

eat rash:

Heat rash, which happens when sweat pores become blocked, may be the cause of small red spots that form on the skin and tickle.

Heat cramp:

Heat cramps often happen when the body perspires heavily but fails to quickly replace water and electrolytes, leading to muscular spasms. Away from heat sources, oral or intravenous fluids, and electrolyte replenishment are the mainstays of treatment.

Heat Syncope:

Dizziness is a temporary interruption in the blood supply to the brain brought on by excessive fluid loss from sweating and low blood pressure.

According to Dr. Ooi Hean, a high temperature may not cause you to experience all of the symptoms at once, but you will simply become more and more exhausted. Consequently, it is advised against venturing outside in the heat, especially between 10 am and 4 pm. In addition, it is advised to drink enough water to prevent dehydration and electrolyte imbalance if you want to go outside, wearing breathable, sweat-absorbent, and light-colored clothes are also advised.
