Chills and shivering are natural reactions as your body tries to fight illness, Dr. Ian Smith explains. Here's why it happens and when to see your doctor.
@@alexisgallegos319 yessss... I have no fever and it's not that cold in d house too..it's just 20 degrees... I feel like I will pass out at times 😭... Don't know wat to do
oh yeah, "praise" your imaginary friend for viruses and bacteria!! WAY TO GO!!! you really set the bar as low as it could go with "wonderfully made". damn you're sad!!
Currently freezing but sweating at the same time. My shirt got really wet from sweat while I had a tank top underneath so you know it’s real. Slept and woke up an hour later to my blanket being wet as well from sweating but I was still freezing cold and there’s a vent blowing heat right above me. This is horrible.
@@rahul11bhat I’m fine now. My little brothers didn’t feel it when they had it, my mom lost her smell and got it back but only felt sick for 4 days. Step dad didn’t get it at all.
My son's first week of daycare he got sick with rhinovirus and passed it to me. It's labeled as the common cold, but it WHOOPED my ass. Within 12 hours onset of symptoms, I had 103.8 fever and I literally had 2 sheets and 4 throw blankets on top of me. It took me forever to warm up. I finally fell asleep and then my body woke me up because it was being smothered. What a ride in hell! I always know I'm coming down with a fever because the chills always start in my lower back and butt.
Just had one of the worst nights of my life. It's winter so I thought I was just cold last night when I couldn't stop shaking for two hours after putting on sweat clothes and extra blankets. That was until I woke up this morning feeling hot and aching with a severe headache from a fever. Now Tylenol and ibuprofen is finally kicking in and I'm drenched in sweat and still feeling ehh but not like I'm on the verge of death like last night and this morning at least.
@@maximbodnar3906 I hope you get better soon. I caught covid somehow. Really frustrated since I worked through the whole pandemic didn't get it and still took precautions afterwards and now I come down with it. I just hope it gets better instead of worse. Day 2 out when my fever breaks+2!
Started shivering last night with horrible chills. Woke up with the worst headache and body aches I've ever had and am sweating and freezing at the same time. Feeling horrible!!
Whenever I get a fever, I'm looking forward to the moment when I sweat like I've just jumped into a pool. Because at that point the fever usually stops and I start feeling better. (Sometimes it takes 2-3 "sweat sessions" before the fever stops... but it's alwaysa big relief). However, that might only work because I'm still young.
Keeping the fever longer to do what it has to do is better if you can sustain it. If you break it too early it'll keep coming back cause it's not done fighting.
imagine ...this is probably what drug addicts go through (often) if they didnt get their fix. Awful. im having a fever right now ( not due drugs haha ) and everytime i start feeling kinda warm, i make sure to even put on another hoodie an drink some tea, to make the body heat up as fast and as much as possible. With this i always noticed i have fewer sweat sessions!
Haha when they haven't had their fix your a total fanny for that , addiction is AN ILLNESS,but a think your a bit soft in the head to realise that ,if you went cold turkey you would probably jump off a roof not a thing to joke about I help addicts and there's always trauma in there life to lead them on that path ,but HAHA a hope to god you never have to deal with it or even a loved one it's not funny it's about as funny as you
I keep feeling hot and cold my headache goes away then comes back , dry mouth only when the headache kicks in.I showered with cold water the water would still feel warm here and there. All these symptoms showed up after I woke up. But I instantly felt the headache when I was waking up. I was super sweaty and my bed was wet with sweat
I’m hot and cold at the same time like I’m under a huge blanket but it’s too hot and when I remove the blanket I’m so freezing Also like my breathing is hot (if that makes sense) like the air that I breath out is like SUPER hot and my chest is really tight 😭
Gabriel Gonzalez of course u idiot. People that actually changed the world for good. The fact that u are even using the phone and the network is possible because of man. Nicola Tesla, Newton, Bill Gates, Babbage, Einstein, Hawkins those are the guys to name a few that deserve the praise. U guys who believe in an imaginary man in the sky are ignorant fools and someone who is afraid to accept the truth. Man created god not the other way round in the agricultural era when they finally moved out of the jungle and savannahs to live in a group. Before there were groups with few members and hunted together and it was also easy to look after others actions. But then in the agricultural era people lived in greater numbers and it was hard to manage people as they would do something bad and no one would notice. Then there was this idea to spread the news of the ever present god so people would feel someone is watching. Less did the know that their lie to make people good in long term will stick like a parasite and causing cancer to the world in future. If u look the data after the industrial revolution and after the golden age of science and technology numbers of believers are decreasing day by day in more and more numbers. Cause people are now educated and know the truth. Imagine after 400 500 years when science will rise even more when technology will be way advanced than what it already is. The whole world in majority will be believe in science. And religion may still be there as moral schools but the bull shit of god will no longer be a thing.
MIKES T3CH well that’s where you’ll be highly disappointed. There’s only ONE GOD. All others are false, the Egyptian Pharaoh Akhenaten tried to crumble all other Gods in place of worship to the one divine God Yahweh. Same thing was Quetzalcoatl, he was the manifesting Jesus that came to the Mayans to throw away the other Gods. It’s all the same one divine entity. The Alpha and Omega. The Narcos of Mexico worship the Black Death and many false Gods, don’t be like them, because in the end, everything will crumble and one will remain as he has since the beginning. That’s how it will be.
I’m literally just getting over the chills and I had to find some type of scientific to explain Wtf this is because I hate it!!! I’m feeling a little better now thankfully but those chills are the worst
I haven’t been able to get out of bed for the last 36 hours. I keep sleeping and then waking up. I got rigors a couple hours ago, I thought it was a seizure because I couldn’t stop shaking
@@kerizmarolle9710 hii my mom actually got better 2 months ago she was sick for about 1 month we didn't really know what it really was after we got her checked and it turns out it was abt her blood it wasn't really serious she just have to to take a rest and drink medicine for blood like iron i can't actually believe that it's been 2 months already shes actually really better thinking abt that time I was really nervous because it was just me and my 2 other siblings we were the ones who took care of her I don't know what could happen to her because watching her that way makes me cry but even tho things are tough I would always pray so happy she's better now thank you for asking i really appreciate that❤️.
Like he said, only something's die in the heat so it's not full proof but the body does it anyways because it doesn't know if you have staph or e.coli all it knows is intruder dead.
Good question. Actually, you should only take medicine if you have a high grade fever. Most of the time, 100-101 is manageable and is best left untreated so your body can use it purposefully. However, if it doesn't taper off or stays high for 2 or more days, you need to see a doctor and take medicine. It's one reason now why pediatricians actually tell you to not give your children medicine to stop the fever before getting vaccinations. It's a natural response and can hinder the effectiveness as long as the fever isn't too high.
It depends on if you can suffer through it or not. Some ppl can deal with a 102 degree fever others like myself can't. I will literally cry, pain/discomfort whatever you wanna call it is not my strong suit! It's not like my body stops fighting the infection it's just not as hostile of an environment which don't forget messes with other cells too when you have a fever.
It’s your soldier fighting off infection inside Don’t kill it by taking something to stop their work Drink lots of water, get out flannel dip in vinegar and put on your forehead
My body has needs to calm down. Legit even the air passing during walking or from opening doors made me shiver. Like I got it I'm looking for a blanket just please stop 😂
taking tylenol helps to relieve those chills. Once you take them later you'll feel the effects kick in and your body starts to heat up like a campfire near you or something. It's a nice warm feeling.
Oh he so didn’t answer the question. Why is it so bad that you feel like you’re dying,yet you explain why it’s normal. Sometimes I’ll slip into bed,and go into violent chills and cramping ,hoping I don’t have a heart attack.
Nice vid, Im on day 5 with this crap lol. The last 3 days I haven’t had shivers but just the warm body and after ibuprofen I start sweating like a pig a few hours later. So each days seems better but I still feel weak lol. Let the ibuprofens come if I have too give a week lmao.
