2023年12月6日 · 發燒通常是身體對感染、炎症或其他疾病的一種反應， 當身體檢測到細菌或病毒等病原體時，免疫系統會釋放熱原（pyrogen），有助於提高免疫系統的效能，抑制病原體的生長。 發燒是指體溫超過正常範圍0.58℃／1℉ 或以上的情況。 而正常體溫通常在攝氏36.5至37.5度之間。 所以當體溫超過38℃我們就稱之為發燒。 當體溫超過39.5℃我們稱之為高燒。 不同種類的發燒. 發燒可以分為不同的類型，其中包括以下幾種： 稽留熱（continuous）：體溫持續徘徊在39至40℃左右，日夜之間的體溫變動幅度很低。 弛張熱（remittent fever）: 體溫持續波幅比稽留熱較大，大約超過1℃左右. 間歇熱（intermittent fever） : 體溫會突然上升到39℃以上，數小時後體溫恢復正常。
2020年7月31日 · Aug. 2020. 發燒温度到底是幾多？ 原來我們的正常體溫已經不再是37℃，而是36.6℃。 新冠肺炎（COVID-19）疫情持續 ，自救自己保護自己最重要。 根據WHO宣布的10大症狀中「發燒」是最常出現的症狀、約有87.9％的感染者都會有體溫偏高的狀況。 身體健康很重要，自己保護自己更加重要，現附上5個探熱方法及衞生署提供的正常體溫表比較！ Gettyimaged.

Body temperatures vary slightly from person to person and at different times of day. The average temperature has traditionally been defined as 98.6 F (37 C). A temperature taken using a mouth thermometer (oral temperature) that's 100 F (37.8 C) or higher is generally considered to be a fever.
Depending on what's causing a fever, other fever signs and symptoms may include:
•Sweating
•Chills and shivering
•Headache
•Muscle aches
Infants and toddlers
A fever is a particular cause for concern in infants and toddlers. Call your baby's health care provider if your child is:
Children
There's probably no cause for alarm if your child has a fever but is responsive. This means your child makes eye contact with you and responds to your facial expressions and to your voice. Your child may also be drinking fluids and playing. Call your child's health care provider if your child:
Adults
Call your health care provider if your temperature is 103 F (39.4 C) or higher. Seek immediate medical attention if any of these signs or symptoms accompanies a fever:

Typical body temperature is a balance of heat production and heat loss. An area in the brain called the hypothalamus (hi-poe-THAL-uh-muhs) — also known as your body's "thermostat" — monitors this balance. Even when you're healthy, your body temperature varies slightly throughout the day. It can be lower in the morning and higher in the late afternoon and evening.
When your immune system responds to disease, the hypothalamus can set your body temperature higher. This prompts complex processes that produce more heat and restrict heat loss. The shivering you might experience is one way the body produces heat. When you wrap up in a blanket because you feel chilled, you are helping your body retain heat.
Fevers below 104 F (40 C) associated with common viral infections, such as the flu, may help the immune system fight disease and are generally not harmful.
Fever or elevated body temperature might be caused by:
•A viral infection
•A bacterial infection
Children between the ages of 6 months and 5 years are at increased risk of a seizure that occurs during a fever (febrile seizure). About a third of the children who have one febrile seizure will have another one, most commonly within the next 12 months.
A febrile seizure may involve loss of consciousness, shaking of limbs on both sides of the body, eyes rolling back or body stiffness. Although alarming for parents, the vast majority of febrile seizures cause no lasting effects.
If a seizure occurs:
•Lay your child on the side or stomach on the floor or ground
•Remove any sharp objects that are near your child
•Loosen tight clothing
You may be able to prevent fevers by reducing exposure to infectious diseases. Here are some tips that can help:
•Get vaccinated as recommended for infectious diseases, such as influenza and COVID-19.
•Follow public health guidelines for wearing masks and social distancing.
•Wash your hands often and teach your children to do the same, especially before eating, after using the toilet, after spending time in a crowd or around someone who's sick, after petting animals, and during travel on public transportation.
•Show your children how to wash their hands thoroughly, covering both the front and back of each hand with soap and rinsing completely under running water.
•Carry hand sanitizer with you for times when you don't have access to soap and water.

發燒是指身體製造過多熱能或身體的 體溫調節 失調，導致身體的溫度高過溫度設定值或溫度設定值本身過高。 [6] 發燒可能是由許多 疾病 造成，從 小病 到 重症 都有可能，這包含了 病毒 、 細菌 、 寄生 、 普通感冒 、 流行感冒 、 泌尿道感染 、 腦膜炎 、 瘧疾 、 闌尾炎 等。 非感染性的發燒成因包含了 血管炎 、 深靜脈血栓 、 藥物的副作用 、 癌症 等。 [13] 另外，發燒不等同 高熱 這個類似疾病，不同之處在於， 高熱 （ 中暑 為 高熱 的一種 [14] [15] ）起因於身體累積的熱能過多或是身體的散熱功能不足，導致體溫超越正常體溫設定點。 治療發燒本身，一般來說是非必要的。
