Body Check – Sweat Transcript

Dr Christian: Whether we like it or not we all sweat.

And without it we’d die. Sweating is essential to regulate body temperature and stop our organs from over heating.

And even at rest in a cool environment a normal person loses about half a litre of sweat in a day.

Some people sweat more than others, usually men sweat more than women and some people can sweat excessively with a condition called hyperhidrosis.

However much you sweat it’s essential to keep hydrated aAnd there’s an easy way to check your sweat rate at home, so you can keep your hydration levels just right.

You need to weigh yourself before and after a work out ñ in the same clothes.

You should keep hydrated while exercising so for an accurate test weigh yourself holding the amount of water you intend to drink. And make sure to hold whatever’s left over for the post training weigh in.

Time how long you exercise for and then use our online calculator to determine how much fluid you’ve lost.

*******

Dr Christian: Come on guys, i wanna see you sweating! Even on this freezing day this is how much fluid these guys have lost.

Dr Christian: Right guys, well I’ve done the maths you managed to lose during in your training session 1.8 kilos. So nearly double actually what a lot of these guys lost. You guys basically, on average, need to rehydrate yourselves with about a litre per hour because that’s what you’re losing. Does that make sense? You probably a little bit more, you need about sort of 1 and a half litres per hour.

********

Dr Christian:Knowing your sweat levels will help you get your levels of hydration just right.

Because if you don’t drink enough, you’re body can’t produce enough sweat to keep itself cool. And this can put a strain on your heart.

If you drink far too much water you’re at risk of over diluting your sodium levels in your blood and this can be fatal.

For this body check and others featured on the site we want to hear about your findings. So please come back and share your results and discuss them with other site users.

And if you have any concerns about your sweat levels or think you may be sweating excessively then make sure to contact your GP.

Body Check: Sweat

Measure your sweat rate in 4 simple steps

Calculate

Weather we like or not, we all sweat and without it we’d die. Sweating is essential to regulate body temperature and stop our organs from overheating. In this video, Dr Christian explains how to keep track of your sweat levels.

You need to weigh yourself before and after a workout in the same clothes, and you should keep hydrated during your workout. For an accurate result, weigh yourself holding your water bottle.
Time how long you exercise for and then use our sweat calculator (above) to determine how much fluid you’ve lost.

Some people sweat more than others in a condition called ‘Hyperhidrosis’. But however much you sweat, it’s essential to keep your hydration levels just right. Knowing your sweat rate will help regulate your hydration levels as not drinking enough water, or drinking too much, can lead to medical conditions.

When I sit down on the chairs at my school I leave sweat marks / patches, I don't want to go to the doctor about it and I haven't told anyone about it. I have seen a few other people leaving marks but not really noticing it. I have to wear the same uniform and the sweat doesn't smell. I also get sweaty after a 12min walk. I am in shape - why does this happen, is there a way to reduce / stop leaving the marks when I sit down? Or just to stop sweating a lot less? (15years old, male)

For as many years as I can remember I sweat from my head, I can be doing nothing and the sweat is pouring down my face and neck, if I do any housework I have to shower afterwards because my hair is drenched with sweat, any idea, I've been prescribed Pro-ban thine 15mg tablets which are supposed to block sweat glands but I'm scared to take it because one of the side effects is overheating, really do t know what to do and ruins my life and I dread summer because although I sweat when others are cold the summer is worse. Please advice.

I have a really embarrassing problem and it is this. My body from my chest down to my waist and same on the back sweats profusely and can saturate through multiple layers when I'm trying to hide it. When it happens my hands and feet are freezing and I feel really cold but at the same time I'm sweating a lot. I don't know anyone else this happens too. Strangely as well there are times when this isn't happening and I tend to be the one who overheats the least but generally i can't even risk wearing a shirt because it will be wet in no time. Take today for instance, I've been at home working on an assignment and all was good and then at about 1400 I just started sweating and my hands and feet went cold. It's been happening for years and is unpredictable. I've tried anti perspirant and it doesn't work and the doctor has no answers, he's sending me to see a botox specialist. I was wondering if anyone else has anything similar. My doctor now thinks it may be an auto immune disorder but all this time not knowing and it's getting worse. Anyone any ideas?

I have a nine year old boy and have found yellow stains where he lays (it is a new bed, only 3 months old) on the mattress protector and quilt. It isn't a strong water mark stain like urine and he is waking up with his boxers completely dry. But the stains smell sickly sweet and slightly of urine. Should I be concerned about this?

Since I have been going through an early menopause, every time I get hot and sweaty there is a really terrible BO smell coming from my groin area - this did not occur previously. This happens even if I get warm immediately after a bath, so not because I haven't washed. This is really affecting my life and making me worry about exercising around others. Also I have to change my underwear multiple times a day.

Try an anti bacterial soap, I find if you scrub well using this in the most sweaty areas it stops the bacteria that causes the odour.

I suffer from excessive sweating. Even in minus temperatures I get it running down my head. I get it all over my body apart from my feet and hands. I'm embarrassed by it and I can't wear decent clothes, I don't 'dress up' because wearing a shirt and tie hinders the problem, I wear shorts all year round, during the winter I have to have the windows open all night, a large circular fan is blowing all night and we have a summer weight quilt on the bed all year, I still sweat, my wife unfortunately is cold and sleeps in jama's or even a jumper sometimes. I've been to the doctors several times about it, recently I was prescribed Driclor but it burnt my neck - it looked like red sunburn and was very sore, he told me to stop using it so I'm no further forward and no better off. I've asked about the operation but have just read on here it's not advisable to have it done. Can you please suggest something, I also suffer from diabetes but the sweating as been a problem most of my life, I was only diagnosed with Diabetes a couple of years ago. It really gets me down.
