為何寒冷要停課？（王永平）

elbar

今星期一，教育局因為天氣異常寒冷，宣布幼稚園、小學及特殊學校停課一天。不過，校舍須保持開放，照顧有需要回校的學生。記得早前教育局長吳克儉被傳媒問及對港大學生會發起罷課的意見時，他的答案是除了有關行動必須合情合理外，還提到近日天氣寒冷，同學要關心身體。大概是貫徹關心學生身體的愛心，吳局長決定在寒冷的一天停課。

立法會議員葉建源透露，教協在發聲明呼籲教育局宣布停課前，曾以手機WhatsApp吳局長，結果在諮詢過一眾中小學校長後，吳局長從善如流。據報部分校長認為學校缺乏暖氣裝備，擔心小學生返校後不適，家長會責難學校。

與建議小三TSA須修正或取消不同，這次停課的訴求不是來自家長。事後家長的反應大部分是無可無不可。有些家長視停課為放假，帶同子女出外玩耍。有些認為當日天氣清朗，交通暢順，因為寒冷而停課是小題大做。

這個小題其實值得討論。往學校上課是孩子成長的必經階段。熱天流汗，冷天穿多件衫，對小朋友只是個適應環境的過程。天氣特別熱或特別凍或會成為日後一段值得懷念的美好回憶。

一向以來，學校停課的原因都是因為出現暴風雨或嚴重意外，令學生在來往學校的途上可能遭遇危險或受到損傷。至於說學校缺乏暖氣設備，這與絕大多數家庭的情況沒有分別。講道理的家長不會因此責難學校。不講道理的家長也不會得到市民大眾的認同。

近年全球氣候變得非常不穩定。香港今次的寒冷可能會重來。香港也可能遇到異常酷熱的天氣。我認為今次停課決定不應成為先例。相反，教育局適宜事後檢討，包括諮詢學校及家長的意見。其實如果除冷熱外，天氣及路面情況一切正常，我認為小學不應停課，因為過度保護小孩子不是教育之道。

世上沒有絕對的天氣預測的, edb 停課的安排也只是根據預測, 事後作孔明, 欲加之罪, 又何患無辭? 也太不公了.

天文台一早預測星期一氣溫須低幾度，但天朗氣清。

　　「小嘛小兒郎，背著那書包上學堂，


　　不怕太陽曬，也不怕那風雨狂，


　　只怕先生罵我懶呀，沒有學問，無臉見爹娘……」


　　因為寒流突襲，教育局於星期一給全港幼稚園及小學生一天突如其來的假期時，我立即想起這首歌。


　　無端端不用上課，孩子們一定樂翻天，家長則分成兩派，贊成的說，別拿我們跟俄羅斯比，香港人沒遇過這種寒冷，學校又沒有暖氣設備，放一天假而已，有甚麼大不了？


　　告訴你，有。那是關乎教育，關乎原則，尤其對於年幼小孩。


　　寒流之下，我們用了一天假期去教導孩子，遇困難是要躲在家，因為家中安全有暖氣，別出去冒險了，即使那裏是安全系數很高的學校。


　　早陣子大家明明拼命推介明珠台紀錄片《翻山涉水上學去》（The Most Dangerous Ways to School），講山區孩子如何走幾小時山路，攀石、過激流去學校；極地兒童如何踏雪求學，一步一雪印的上課去；非洲少年怎樣越過沙漠，頂著烈日尋知識的甘露……然而一天假期，就把一切教育推倒，香港的孩子冷不起，不用上課了，戶外活動都取消。我覺得大家怕孭鑊多於怕孩子冷。


　　贏在多遠的起跑線又有甚麼用呢？一個寒流就把你們嚇退、擊倒。今日的讀書郎，已名副其實變成「又怕太陽曬，又怕風雨狂」了。

Preven​​ting cold weathe​r injuries Cold weather injuries can be life or limb threatening. The best way to avoid these injuries is to:
Be aware of the current and forecasted weather before going outside in the cold.
Take note of the 'wind chill factor'. This measures how much colder the body feels and how much faster the body loses heat depending on how much the wind is blowing.
Dress properly for the outside temperature and for the activities you will be doing. For tips on staying warm this winter, visit our page on dressing for the cold.
Supervise children in the cold. Frostbite, hypothermia and other cold-weather injuries can come on in minutes. If children are excited about playing outside, it is easy for them not to notice minor discomforts and the first signs of cold-weather injury. If a child is shivering, it is time to head back inside. Older children, teens and others participating in outdoor winter activities should be encouraged to use a "buddy system" to look for early signs of frostbite in each other.
  
Frostbite
Frostbite occurs when body tissues freeze causing cell death. First, the water around the cells freezes and then the cell is cut off from its oxygen supply. Exposed skin and extremities such as fingers and toes, nose, ears and cheeks are most commonly affected. Frostbite can be superficial, meaning it only affects the skin, or deep, meaning it affects body tissues below the skin. Frostbite can be an emergency; if not treated it can lead to severe injuries and even loss of digits or limbs.

Signs of frostbit​e

At first, a child with superficial frostbite will feel burning, numbness, tingling, itching or cold sensations in the affected area. This area may appear white or more pale than usual.
If you press on the skin, it should depress more or less as usual. As frostbite gets worse and becomes deep, the sensations will decrease and may disappear. The area will swell and the skin will appear white and waxy. The affected area will also be hard and will not depress if you press on the skin. It may be difficult to move the affected area. For example, the person might feel like their fingers or feet are clumsy. In addition, blisters filled with blood or fluid may develop.
In very serious cases, the skin will go black. In mild or moderate cases of frostbite the skin may become quite painful after it rewarms and even peel. An area of skin that has been frostbitten is more likely to be affected again.
Treating superficial frostb​ite
Get warm. Move indoors or somewhere warm to prevent further heat loss. If your child’s feet are frostbitten, carry your child somewhere warm to prevent tissue damage. Elevate the affected area.
Give your child warm, non-caffeinated fluids to drink. If no warm drinks are available, have your child sip water.
Remove wet clothing and anything that may limit blood flow.
Do not rub the affected area. Do not heat the area with anything hot enough to burn the skin. Constant warming is best. Wrap your child in a blanket in a warm room. You can also use your own body heat to warm the area. For example you can tuck the child’s affected body part under your arm pit for rewarming. Try rewarming the area by placing it in warm water. Make sure that the water is NOT hot.
As the affected area warms and the skin colour returns to normal, it may be a little painful.

Treating deep fros​tbite

If your child has deep frostbite, call or go see a doctor right away Use all the treatment measures described above.
Do not start warming the affected area if the warming cannot be continuous. Thawing and refreezing will increase tissue damage. Only thaw when you are sure that the area will no longer be exposed to the cold.
If the fingers or toes are affected, apply a dry bandage between them to avoid rubbing. Your child will be in pain as the affected area thaws and blood flow returns. It will begin with a dull ache and may turn into a throbbing pain. Depending on the severity of the frostbite, this may last for several days. The affected area may turn purple or blue as it rewarms.
The amount of tissue damage may not be known for some time.

Hypother​mia
Hypothermia happens when the body’s core temperature drops below normal. It is a life-threatening medical emergency. Hypothermia is more common among small children and the elderly.
Signs of hypoth​ermia
Hypothermia means the body temperature has fallen below 35°C (95°F). When the body is this cold, the brain is affected and clear thinking becomes difficult. People with hypothermia are often confused and disoriented. This makes the condition even more dangerous because they may not notice that anything is wrong.
Symptoms include:
shivering (until hypothermia becomes severe and then the shivering stops)
clumsiness
tiredness
memory loss and confusion
slurred speech
pale skin; blue hands and feet
breathing fast
Treating hypothermia
Hypothermia needs immediate action. If your child shows any of the signs listed above, move to a warm place and call for help. If you can, take your child’s temperature. If it is below 35°C (95°F), the situation is an emergency. Go see a doctor immediately or call 911 for help.
If medical care is not available, or if you are waiting for help to arrive, begin warming your child, as follows:
Get your child into a warm room or shelter.
Remove any wet clothing.
Warm the centre of the body first — chest, neck, head and groin — using an electric blanket, if available. Or use skin-to-skin contact under loose, dry layers of blankets, clothing, towels, or sheets.
Give your child sips of a warm beverage. This can help increase the body temperature,
After their body temperature has increased, keep your child dry and wrapped in a warm blanket, including the head and neck.
A person with severe hypothermia may be unconscious and may seem not to have a pulse or to be breathing. In this case, handle the person gently, and call 911 immediately. Even if the person does not appear to be breathing, someone should give CPR. CPR should continue while the person is being warmed, until they respond or medical aid arrives.
Drinking warm fluids in winter
Dehydration
Dehydration is a lack of water in the body. People tend to think of dehydration as a heat-related issue. However, dehydration occurs very quickly and easily in cold temperatures. People frequently do not notice dehydration and may not feel thirsty in the cold.
Always make sure children drink plenty of warm fluids to help the body maintain its temperature. If hot drinks are not available, drink plenty of plain water. Make children drink water before going out into the cold. Encourage children sip water even if they do not feel thirsty.
Signs of dehydratio​n
restlessness, drowsiness and irritability
cold or sweaty skin
low energy levels, feeling weak or limp
no tears when crying
dry sticky mouth and/or tongue
sunken eyes or sunken soft spot (fontanels) on baby’s head
smaller amounts of urine (pee), no urine over eight to 12 hours, or dark-coloured urine
Treatment of dehyd​ration
Begin with sips and gradually increase the amount of liquid. In addition to water, dehydration also includes a loss of salt and sugar. If possible, give your child an oral rehydration solution such as Pedialyte, Gastrolyte, Enfalyte or other brands containing a properly balanced amount of water, sugars, and salts. If you have an older child or a teenager, then you can give them a sports drink.
If your child is unresponsive, go see a doctor right away.

讚同停課與否，都瞭解一下低溫症對人嘅影響。

事實上放假一天沒有甚麼大不少，有上課的學生也不會特別聰明。但原則影響思維，思維決定態度，不可掉以輕心。

國際學校輕輕kan kan,臨近假期，總有家長為提早出門，讓孩子告假兩三天，來趕上平價機票酒店旅遊，看似十分精打細算，其實蝕洒本。這點漠視上課的輕率態度，間接令孩子覺得個人需要比老實上課重要得多，結果孩子非常confused, 容易把上學看成次要之事，那還會用心學習嗎？

以上是題外話，個人有感而發的分享吧！並非指這些現象與寒天停課對等。

停課個決定做得好好，可以預早俾家長去安排照顧子女。
咁岩星期一果天氣無落雨，如果係比星期日更加惡劣，其實中學生都要停課。

你說得對，放假—天也沒什麼大不了，溫室的小花不會因為冒寒上課—天就變成堅強的雄鷹，相反，堅強的雄鷹也不會因少了—天嚴寒的鍛鍊而成溫室的小花。所以成蟲成龍，也不是一朝—夕的事，而是由點點滴滴的小事養成的。心態決定高度

爬喜馬拉雅山就有 frostbite 者，香港三幾度又 frost bite 又 life threatening? 我地的孩子幾時咁弱不禁風？

市區三度 life threatening，下次四度五度六度也很利害，又 wind chill，停唔停課？

好多人就是不明白這一點，為什麼停一日課咁多人批評。

TEMPO123

每間學校不是都有暖氣提供，穿過多衣裳在窄小桌子上寫字也不暢順。
這期間，長者都容易病，不停課，學生又病，記得當日還有人上大帽山，
不停課，也許會造成消防、警察、醫護都應付不來的情況。

其實，學校仍然開放，不同意見者，仍可帶小孩上堂，有何問題？

其實即使停了課，現在很多診所入面都坐滿了人，可以想想，不停課會更甚了。

事實証明, 弱勢政府, 做乜都要被人抽水.

不過今次事件, 証明了王X平, 屈X妍, 陶X等都只係一丘之駱.

批評停課的家長, 請問你們又如何培養子女, 等佢地唔駛經不起磨練?

家中有否裝冷氣? 有?! 點解? 天氣熱係正常現象喎? 你地小時候無冷氣咪又唔駛死?

得3度時家係咪沖緊熱水涼? 係?! 點解? 你話要生活體驗, 咁點解唔係3度時叫個小朋友沖凍水涼? 做乜要開晒暖爐沖熱水涼?

批評很容易, 只會批評而沒有提供有意義的建議, 其實同發聲機器又有何分別?
