Increased heat conditions have been recorded recently in most parts of the country. Exposure to excessive temperatures for a sustained period can pose health risks ranging from relatively mild rashes and sunburn to a heat stroke or a medical emergency.

To prevent heat-related illnesses, minimise exposure, reduce physical activity and stay well hydrated. Know the warning symptoms of heat illnesses and what to do if they develop.

International SOS on Thursday shared the tips titled Bangladesh: Heatwave, minimise exposure and stay well hydrated.

A mild to severe heatwave had been noted in most parts of the country. Temperatures have reached as high as 43 degrees Celsius (109.4 degrees Fahrenheit) in some locations, with outdoor workers and children reported to be most affected by the hot weather.

The meteorological department has confirmed that the situation has worsened due to increased humidity.

They advised citizens to do the following :

Monitor updates on the Bangladesh Meteorological Department website and follow the advice of authorities.

Minimise time in the sun, especially during the hottest hours of the day.

Avoid vigorous physical activity during the heatwave.

Stay in cool, air-conditioned environments if possible.

If you must go outside, limit time outdoors, take breaks often and wear natural fibre, light-coloured, loose-fitting clothing, a hat and sunglasses.

Use an effective sunscreen. Drink plenty of fluids. Avoid alcohol, caffeinated drinks and sugary drinks.

Rest immediately in a cool, shaded place if you begin to feel weak or dizzy. Seek medical assistance if the symptoms persist.

What are the health implications of heatwaves?

Exposure to high temperatures can pose health risks ranging from relatively mild rashes and sunburn to heat stroke. Young children, older adults and people with underlying health conditions are at higher risk.

Sunburn develops when the skin is overexposed to ultraviolet (UV) light from the sun. The result is red, painful skin that sometimes becomes swollen and blistered. Severe sunburn can also cause chills, fever, nausea and vomiting.

Heat rash, sometimes called ‘prickly heat’ or ‘miliaria’, often occurs on skin covered by clothing. The rash may cause no symptoms or may itch or sting. Once in a cooler environment, it often gets better on its own. Occasionally, treatment may be required.

Heat exhaustion is a risk, especially for elderly people and those who work or exercise in hot environments. Initial symptoms are excessive sweating and muscle cramps. These can progress into fatigue, headaches, dizziness, fainting and other symptoms. The situation is more serious if dehydration symptoms develop (dry skin and mouth, increased thirst and a fast pulse).

Heat stroke is a serious illness that occurs when the body's cooling mechanism fails due to prolonged exposure to high temperatures. It is a medical emergency. Body temperature may rise to 41 degrees C (106 degrees F) or even higher as quickly as within 15 minutes.

In addition to fever, patients may become confused, disoriented and uncoordinated and have trouble speaking or understanding others. These are signs of a serious illness. Heat stroke can cause death or permanent disability if emergency treatment is not provided.
