What temperature do you need to have a fever?

I've been feeling a bit off, and my head feels heavy. I checked my temperature, but I don't know the exact threshold. What temperature do you need to have a fever?

For adults, generally anything at or above 100.4°F (38°C) is considered a fever. But don't just rely on numbers. If you're feeling really unwell, or if it persists, it's always safer to get it checked by a doctor, just in case.

Ugh, fever! The worst part is losing your appetite for all the good food. Generally, it's 100.4°F (38°C). But if it's less than that and you still feel off, maybe just go for some nice warm soup and rest, haan?

My friends and I always say if it's above 100, you're officially 'sick leave worthy' haha. But yeah, science says 100.4°F (38°C) for a proper fever. Below that is just feeling warm, maybe from too much stress or something.

My mother used to say, 'If your head feels hot and heavy, it's fever'. But medically, for adults, the threshold is 100.4°F (38°C). If it goes beyond that, or you have other symptoms, please do consult a doctor. Don't delay.

My fever starts when my wife makes me drink bitter kadha, ha ha. But seriously, doctors say 100.4°F (38°C) is the official limit. Below that, I just call it 'feeling a bit off' and still go to work. The joys of being middle-aged.

Haan ji, usually it's considered a fever when your temperature is 100.4°F (38°C) or higher. But listen to your body, ho na? If you're feeling really unwell even with a lower temp, rest is important.

From my experience, the 100.4°F (38°C) mark is generally correct for adults. Keep a good digital thermometer at home. If it hits that, take a paracetamol and rest. If it doesn't come down or gets worse in a day or two, then it's time for the doctor.

Quick answer: 100.4°F (38°C). Anything below that might just be stress or fatigue. If you hit that number, consider it a fever. Take a day off, rest, and hydrate. If no improvement, see your doc. Don't drag it out at work.
