極端高溫天氣可以非常危險。了解中暑、熱衰竭的症狀,以及如何為酷熱的季節做好準備,以保護您自己以及您的鄰居、朋友和家人的健康。

高風險人士

高溫對每個人的影響不盡相同,但有些人的健康可能更容易受到影響。以下人士特別需要注意保持涼爽:

  • 60 歲或以上的年長者
  • 獨居者
  • 已患有例如糖尿病、心臟疾病或呼吸系統疾病等健康問題的人士
  • 患有思覺失調症、抑鬱症或焦慮症等精神疾病人士
  • 患有物質使用疾患的人士,包括酗酒
  • 行動不便人士
  • 邊緣無定居所者
  • 在酷熱環境中工作的人士
  • 孕婦
  • 嬰兒和幼兒

其他人士也會受到酷熱天氣的影響。每個人的反應都不同,所以要多留意自己的身體狀況。

酷熱天氣對健康的影響

極端高溫事件,也稱為「熱浪」,可能導致多種高溫相關的疾病,並增加死亡率。高溫相關的疾病是指因酷熱天氣引起的不適,例如熱疹、曬傷、熱痙攣、熱衰竭,以及最嚴重的中暑。

 

熱衰竭的症狀包括:

  • 大量出汗
  • 頭暈
  • 噁心或嘔吐
  • 呼吸急促和心跳加速
  • 頭痛
  • 注意力難以集中
  • 肌肉痙攣
  • 極度口渴
  • 新出現的皮疹
  • 尿液深色和排尿量減少

任何有熱衰竭症狀人士都應該轉移到涼爽的地方、喝水,並在大面積皮膚上敷冷水(涼水浴、淋浴或弄濕衣服)。應立即採取這些步驟,因為熱衰竭可以很快進展成中暑,到時就是醫療緊急情況。

中暑的症狀包括:

  • 體溫高( > 攝氏 38 度/華氏 100 度)
  • 昏厥或嗜睡
  • 意識錯亂
  • 缺乏協調能力
  • 非常熱和紅的皮膚

中暑是緊急醫療情況。需立即前往急診室或緊急護理中心求醫。如有必要,請致電 911。在等待幫助期間,可以的話,立即將患者移至涼爽的地方降溫,並在大面積皮膚上敷冷水(冷水浴、淋浴或弄濕他們的衣物)。

在酷熱天氣下保護自己和他人

待在涼爽的地方,並多喝水是預防與高溫相關疾病的最佳方法。

  • 尋找涼爽的室內和室外空間(例如當地社區中心、圖書館或購物中心。)
  • 即使您並不口渴,也請多喝水和其他飲料以保持身體裡的水分。
  • 用水降溫,如沖冷水澡或將身體的一部分浸入冷水浴中。
  • 穿上濕衣服或用濕毛巾敷在皮膚上降溫。
  • 穿上寬鬆、淺色且透氣的衣服。
  • 限制活動,尤其是在一天中最炎熱的時段(在卑詩省通常是下午 2 時到 4 時。)
  • 上午 10 時左右關閉窗戶,並拉下室內/室外遮陽簾/百葉簾,將涼爽的空氣保留在室內和阻擋陽光。
  • 晚上 9-10 時左右打開門窗,讓涼爽的夜間空氣進入(確定室外溫度比室內低。)
  • 策略性地使用一台或多台風扇,以幫助將較涼爽的空氣在晚間過夜時抽入家中。
  • 使用通常位於廚房和浴室的排風扇,將室內的熱氣排到室外,並在晚間過夜時打開窗戶抽入較涼爽的室外空氣。
  • 考慮於家中安裝空調;如有空調,請確保開啟。
  • 監測自己和被照護者人士的室內溫度。
  • 留意熱衰竭和中暑的症狀。對於易因高溫而引起不適的人士而言,室內溫度超過攝氏 26 度(華氏 78 度)的情況下,患上高溫相關疾病的風險可能會增加,而在室內溫度超過攝氏 31 度(華氏 88 度)時,風險甚至會大幅度增加。

山火的煙霧也會對健康構成影響。如山火煙霧和酷熱天氣同時出現時,請考慮使用備有高效濾網 (high-efficiency particulate air, HEPA) 的空氣淨化器來過濾空氣。了解更多關於山火煙霧的資訊

經常查看您的鄰居、朋友和家人,確保他們能夠保持涼爽,並制定應急計劃。這樣可以挽救生命。

在以往的酷熱天氣出現時,大部分死者都在家中並是社交孤立的人士。

高溫警告和極端高溫緊急情況

為了應對 2021 年的熱蓋侵襲,多個衛生部門合作夥伴和加拿大環境及氣候變化部 (Environment and Climate Change Canada, ECCC) 為 2022 年夏季制定了卑詩高溫警報和應變系統(BC Heat Alert and Response System, BC HARS)。這個由兩個警戒級別構成的系統,列出了加拿大環境及氣候變化部 (ECCC) 發佈高溫警告(第 1 級)或極端高溫緊急警報(第 2 級)的標準,並配合這兩項警報的公共衛生資訊,以及為衛生部門和其他合作夥伴的行動建議。卑詩省將在未來幾年繼續完善和改進卑詩高溫警報和應變系統(BC HARS)。

Vancouver’s Indoor HEAT Study (2021-2023)

In 2021, Western Canada experienced an extreme heat event caused by a heat dome that resulted in 619 heat-related deaths across BC. In the weeks following, a team of health and climate professionals at Vancouver Coastal Health, BC Centre for Disease Control, and the City of Vancouver identified indoor temperature as a data gap in the region. To address this gap, these organizations designed a multi-year study – the Indoor Household Exposure to Ambient Temperatures (HEAT) Study – to collect temperature, building, and household data from residents living in Vancouver, BC. The goal of this work is to help inform recommendations for achieving safe cool temperatures inside existing buildings and help prevent heat illness.

2021 BC Heat Dome and VCH ER Visits

Following the 2021 BC heat dome, the VCH Public Health Surveillance Unit studied data on emergency room visits in collaboration with VCH and Providence Health Care Emergency Medicine programs. Several key findings were identified:

The extreme heat event that affected much of British Columbia in 2021 resulted in a substantial increase in Emergency Department visits related to heat-related illness in VCH hospitals.

Rates of heat-related Emergency Department visits varied substantially by area of residence. Among the urban neighbourhoods in the VCH region, a higher rate of heat-related ED visits was observed among residents in the Downtown Eastside, Kensington, Victoria-Fraserview, North Vancouver City-East/West, and North Vancouver District Municipality –Central.

Among age groups, the highest rate of heat-related ED visits was among those aged greater than 80 years. Slightly more than half of heat-related ED visits and over 90% of hospitalizations among these visits were among those aged 65 years or older.

Comprehensive heat event preparedness is essential to minimize future health impacts, as the risk of extreme heat events in the context of a warming climate continues to evolve.
