Homeostasis 3, Thermoregulation

Goldilocks liked the portage not too hot, not too cold, just right is best. This is the physiological principle of homeostasis, numerous parameters must be finely controlled to maintain the correct internal environment for out biochemistry, which gives rise to our physiology, which gives rise to our life.

Dr John Campbell, you're actually a blessing to me.

[@gummies2014]

What an incredible Professor. Just blown away by how interesting and how easy he makes the content.

[@uyennguyendoto9325]

I love your videos so muchhhhhh Dr. Campbell.

[@annaterese7855]

Wonderfully informative and made so interesting. I'm studying Biomedicine and wish you were my tutor online - your videos bring medicine and physiology to life in both a real and amazing way. Looking forward to watching more - a thankful student :-)

[@laithalshammary995]

Thank you so much Dr. Campbell! I have my final exam in 2 days and this video helped me so much! Looking out for more great videos.

Just thank you Dr.John, Thermoregulation was a subject I dreaded, never thought Ill understand it thank you soo much❤️

[@ghodi3921]

Very organized explanation. Thank you very much.

[@VENOM_568]

Your explanation is really good! thank u so much doctor💜

[@pataniki8034]

working well-summer 2019 current temps in europe may reach 40c and here in usa already 37c and uv at 11.5 so this is a gr8stream of insight into what and how-why-physiological adaptation-behavioral changes of that ole dilation -thermodynamics of releasing the sweat gland thru the blood flow exit detox and water loss-so keep fluid intake up and add electrolytes-nice insight on dry vs humid environments-liquid2vapor and heat energy of latent evaporation- people who cant sweat should take quick cool showers outside in sun-to rebalance works out here in so ea az desert-very cool share-manythxs

[@marcoquattroventi7888]

Thank you so much Sir for the great explanation. May God bless you.

Thank you , sir !

[@comeflywithlee433]

+Dr John Campbell When you have an infection why can your temperature start to go the other way as is too low (without medication and without naturally overcoming the infection). Is this a sign the infection has progressed to a new stage?

[@Pompeybell]

All your videos are of great use, many thanks. One question I have is why do we give anti pyrexia drugs to sick patients? Is this not counter productive?

[@SaiKumar-wc1wr]

Awesome explaination

[@thiagarajang6813]

Excellent

[@zuhairyassin505]

what about superficial veins enlargment is it a mechanism or is it secondary to the arteriolar vasodilation ?

[@MuhammadAfzal-ie3vt]

Thanks a lot!

[@Acarloleonard]

dammm dr cambell back at it again with them great vids

[@kylejoshua6277]

+augustus leonardo faaa this guys the man soooo carry

[@annienyirenda4764]

Good lecture and video would you as well distinguish between homeostasis and allostasis.

[@thevoid8238]

EXCELLENT

[@yasirrafiq7389]

thankyou very much dr cambell for this vedio. i m 35 y/o m. i suffehyperhydrosis generalised hyperhydrosis. i cannot bear temperature more than 22 centigrade. i sweat non stop very fast. can u plz help me to kn why my body cools me when its only 22 degrees. life is too much hard with this tremendous sweating. my all harmones . brain mri are nor. i dont have any chronic diseases. plz explain how to not sweat?. thankyou sir.

[@ashutoshbhakuni303]

+Dr John Campbell Does it mean that when we feel so uncomfortably hot during fever (and we havent taken medicine), the body has overcome the infection and lowered the set point? Also, till when should the elevated set point be left uninterrupted and when should one take medicine?

[@Campbellteaching]

I can see what your thinking is, and it does make some sense. However, it is difficult to generalise this complex situation into simple rules, this is where your clinical judgment comes in.

[@newton464]

excellent!

[@lourdzv]

super helpful!!!!

[@mariemarie6545]

Does this mean we should not give antipyretics if a patient has a fever and they are having a rigor?

[@alexluvahand2993]

What's real functions of a prostaglandins? Because it's included in peptic ulcers

[@rajanaidu2617]

Very good presentation sir

[@MrEthanhines]

Dr Campbell what is occurring in the body when a person experiences a hot flash such as in the beginning of menopause?

[@kifetewadane3824]

thank you dad

[@nancydeena8127]

Dad????

[@billytowney1303]

Good video but once I heard the nasal inhalations it's all I could notice.

[@laterisaferondii1435]

I have a TBI from a head on collision 7 years ago ....I began to notice I could no longer tolerate warm to hot temperatures above 90 degrees . after 2nd covid infection in sept 2020 it hit my brain and after now I cannot take any heat over 75 degrees . it feels like 100 plus ., producing a heat stroke type reaction . i have to stay inside summers with air conditioning. this has made my life very frustrating . Can you tell me what has happened ...?

[@notion14]

Sir,.. Does heat intolerance play a role here..

[@maryhellard7270]

If you feel so hot but your skin feels so cold! What's wrong

[@mdv5845]

37 degrees centigrade is considered normal so why are you using 35? The Thyroid gland is responsible for regulating body temperature. It also regulates the metabolism. The T3 is what the body actually uses. T4 converts to T3 in the liver. Doctors say that a small amount of T3 is produced by the thyroid gland which is pure poppycock. That would interrupt the hypothalamic feedback system. Low Thyroid causes low body temp which causes a person to feel hot all the time (The ignorant doctors tell you that you feel sensitive to cold which is backwards - Thermodynamics). It also can cause the arteries to clog faster due to lethargy of the metabolic system. Perspiration is used to assist in regulating body temperature. Severe cold can cause the body to eliminate liquid to prevent freezing. So, if you fall into cold water and get rescued, blankets and warm liquid is a must to replenish the needed fluids and bring the body temperature back to normal quicker. I wrote a Point Paper about the Thyroid. I have suffered needlessly at the hands of very ignorant doctors. I have Pituitary damage and have hormone deficiencies making my life miserable. Especially the ignorant doctors unable to understand the physiological processes of the human body. Refusing to listen to a patient and recognize physical symptoms can cause severe harm to a patient. Good day, sir.
