But all that focus on fever raises an important question: What is considered a normal body temperature, exactly?\nThe temperature of 98.6° F has been deemed the standard, but recent research calls that number into question. Here, a doctor explains why everyone has a slightly different “normal” and when to be concerned.\nWhat’s considered a normal temperature?\nWhile 98.6° F is considered a “normal” temperature most of the time, it’s not entirely accurate. That number was\ndetermined\nby German doctor Carl Wunderlich in the 1800s, and it just kind of stuck. But more recent research has landed on different numbers, including a 2020 study published in the journal\neLife\n, which found that the average body temperature is more like 97.9 degrees.\nThe\nU.S. National Library of Medicine\nalso acknowledges that a normal body temperature isn’t entirely clear-cut, noting that it varies by person, age, activity, and time of day. It can range from 97° to 99° F, the organization says, but\n98.6° F is still considered the norm by many doctors\n—even though it’s basically an estimate.\nHow can you find your own normal body temperature?\nAgain, everyone’s “normal” body temperature varies, and it can even change at different times of day. “Evening temperatures tend to be higher,” says\nRajeev Fernando, M.D.\n, an infectious disease expert in Southampton, NY.\nTo figure out your own baseline, he recommends\ntaking your temperature\nwhen you feel well at the same time every day with the same kind of thermometer. You won’t necessarily get the exact same temperature each time, but you should get readings that are fairly similar, Dr. Fernando says.\nSo, what temperature determines a fever?\nIt’s considered\n100.4° F degrees or higher\n, according to the\nCenters for Disease Control and Prevention\n(CDC). But, like a normal body temperature, a fever isn’t necessarily cut and dry, either. The CDC also says you can have a fever when you feel warm to the touch, you have a history of feeling feverish when a thermometer isn’t available, or you have a flushed face, glassy eyes, or chills.\nWhat about the in-between area?\nIt’s “definitely a concern” for COVID-19 if you notice your body temperature slowly creeping up, even if it hasn’t hit 100.4° F degrees, Dr. Fernando says. “Fever is the slam dunk symptom with this illness,” he says. If your temperature is going up, Dr. Fernando recommends calling your doctor and letting them know what your baseline temperature is (if you know it) and how much higher it’s gone.\nYour doctor will also want to know about your other symptoms, Dr. Fernando says—\nwhich can vary wildly\n. While fever,\ndry cough\n, and\nshortness of breath\nsignal COVID-19, other signs to watch for include fatigue, sore throat, headaches,\ndiarrhea\n, and a\nlost sense of smell\n. “Don’t just use temperature as a measure,” Dr. Fernando says. “If you’re starting to feel ill, that’s more important.”\nSupport from readers like you helps us do our best work.

The temperature of 98.6° F has been deemed the standard, but recent research calls that number into question. Here, a doctor explains why everyone has a slightly different “normal” and when to be concerned. ## What’s considered a normal temperature?* While 98.6° F is considered a “normal” temperature most of the time, it’s not entirely accurate. That number was [determined](https://www.jstor.org/stable/4457716?seq=1#page_scan_tab_contents) by German doctor Carl Wunderlich in the 1800s, and it just kind of stuck. But more recent research has landed on different numbers, including a 2020 study published in the journal [eLife](https://elifesciences.org/articles/49555), which found that the average body temperature is more like 97.9 degrees. The [U.S. National Library of Medicine](https://medlineplus.gov/ency/article/001982.htm) also acknowledges that a normal body temperature isn’t entirely clear-cut, noting that it varies by person, age, activity, and time of day. It can range from 97° to 99° F, the organization says, but 98\.6° F is still considered the norm by many doctors—even though it’s basically an estimate. ## How can you find your own normal body temperature? Again, everyone’s “normal” body temperature varies, and it can even change at different times of day. “Evening temperatures tend to be higher,” says [Rajeev Fernando, M.D.](https://www.castleconnolly.com/doctors/profiles/rajeev-fernando-infectious-disease/), an infectious disease expert in Southampton, NY. ## Related Stories - [![](https://hips.hearstapps.com/hmg-prod/images/how-to-take-temperature-1584979245.jpg?crop=1.00xw:0.752xh;0,0.115xh&resize=300:)Here’s the Best Way to Check Your Temperature](https://www.prevention.com/health/a31784518/how-to-take-temperature-with-thermometer/) - [![](https://hips.hearstapps.com/hmg-prod/images/young-woman-hands-holding-white-digital-thermometer-royalty-free-image-1609719798.?crop=0.774xw:0.580xh;0.205xw,0.395xh&resize=300:)Mild vs. Severe Coronavirus Symptoms](https://www.prevention.com/health/a32006916/mild-coronavirus-symptoms/) To figure out your own baseline, he recommends [taking your temperature](https://www.prevention.com/health/a31784518/how-to-take-temperature-with-thermometer/) when you feel well at the same time every day with the same kind of thermometer. You won’t necessarily get the exact same temperature each time, but you should get readings that are fairly similar, Dr. Fernando says. ## So, what temperature determines a fever? It’s considered 100\.4° F degrees or higher, according to the [Centers for Disease Control and Prevention](https://www.cdc.gov/quarantine/air/reporting-deaths-illness/definitions-symptoms-reportable-illnesses.html) (CDC). But, like a normal body temperature, a fever isn’t necessarily cut and dry, either. The CDC also says you can have a fever when you feel warm to the touch, you have a history of feeling feverish when a thermometer isn’t available, or you have a flushed face, glassy eyes, or chills. ## What about the in-between area? It’s “definitely a concern” for COVID-19 if you notice your body temperature slowly creeping up, even if it hasn’t hit 100.4° F degrees, Dr. Fernando says. “Fever is the slam dunk symptom with this illness,” he says. If your temperature is going up, Dr. Fernando recommends calling your doctor and letting them know what your baseline temperature is (if you know it) and how much higher it’s gone. Your doctor will also want to know about your other symptoms, Dr. Fernando says—[which can vary wildly](https://www.prevention.com/health/a32006916/mild-coronavirus-symptoms/). While fever, [dry cough](https://www.prevention.com/health/a31927676/what-does-dry-cough-mean/), and [shortness of breath](https://www.prevention.com/health/a31701183/what-is-shortness-of-breath/) signal COVID-19, other signs to watch for include fatigue, sore throat, headaches, [diarrhea](https://www.prevention.com/health/a32046157/diarrhea-coronavirus-symptom/), and a [lost sense of smell](https://www.prevention.com/health/a31899309/loss-of-smell-coronavirus-symptom/). “Don’t just use temperature as a measure,” Dr. Fernando says. “If you’re starting to feel ill, that’s more important.” * Support from readers like you helps us do our best work.

Readable Markdown	A [fever](https://www.prevention.com/health/a20429676/how-to-break-a-fever/) is one of the telltale [symptoms of COVID-19](https://www.prevention.com/health/a31698322/coronavirus-vs-flu-vs-allergies/), the respiratory illness caused by the [novel coronavirus](https://www.prevention.com/novel-coronavirus/), so it’s understandable if you’re paying much more attention to your temperature than usual. But all that focus on fever raises an important question: What is considered a normal body temperature, exactly? The temperature of 98.6° F has been deemed the standard, but recent research calls that number into question. Here, a doctor explains why everyone has a slightly different “normal” and when to be concerned. ## What’s considered a normal temperature? While 98.6° F is considered a “normal” temperature most of the time, it’s not entirely accurate.
