Dear Dr. Mo: Is Zinc helpful in treating the common cold? Should I use it?
Dear reader: When we catch the infamous cold (acute upper respiratory tract infection), sometimes the symptoms may be severe enough that we reach out to anything that has even a hint of a promise of a quick cure.
The truth is, there’s no effective cure other than our own immune system and yet, many supplements are out on the market claiming to boost the immune response and help us fight off the virus.
Evidence is strong against any substantial effectiveness of any of these supplements.
Healthy diet and exercise remain the only sure fire ways to overcome the common cold – yes, even while you’re sick, if you can, you should moderately exercise (or at least stay active) and not rest for too long – this will speed up the recovery.
Zinc time and again emerges as one of the supplements suggested to help us fight the common cold but, does it work? Continue reading …
Dear Dr. Mo: What exactly is ‘common cold’ and how to recognize it – is that the same as flu? Should I be worried and what to do?
Dear reader: These days you can’t seem to escape people who sneeze, cough, have a runny nose or all of it together – in fact, you may be one of them.
Don’t worry, it’s usually nothing serious, just a mild viral infection of upper airways also known as common cold and it requires no special treatment.
Chicken soup helps in recovery
The symptoms of common cold may bug us for up to two weeks at a time and if we can maintain our daily function, if there are no serious muscle or joint pains, no high fever or strong headaches and prolonged fatigue it’s not the flu or other serious conditions and you shouldn’t be concerned. But if symptoms persist even after two weeks or start to get worse after 7 – 10 days, visit your doctor to see what’s going on.
Over 100 viruses can cause a common cold and you may experience anything from a runny nose to sore throat, cough and sneezing to watery eyes and strong congestion. Part of the package may also be mild muscle ache and headache, slightly elevated body temperature, mild fatigue and upset fellow elevator passengers. Those unlucky enough may get all these symptoms at once. Continue reading …
Dear Dr. Mo: Is sauna really healthy and should I go there when I have a flu?
Dear reader: When you are in most saunas, its dry heat, which can become as high as 85° C (in some saunas, even higher), can have some intense effects on the body.
Your skin temperature spikes to about 40° C within minutes. The average person will pour out a half a liter of sweat during a short stay in a sauna.
Saunas have been around for centuries – its relaxing and well-being effects on the body are well known
The heart rate jumps by 30% or more, allowing the heart to approximately double the amount of blood it pumps out each minute (its minute volume).
Stress hormones ACTH and Cortisol rise substantially while Adrenalin and Noradrenaline are reduced; other changes in hormonal balances happen as well.
These effects (vigorous sweating, increased heart rate and hormonal changes) are similar to those induced by a moderate exercise, which is why saunas could be so appealing.Circulation patterns change while in sauna and most of the extra blood flow is directed to the skin, which becomes reddish; the circulation actually diverts blood away from the internal organs.
Blood pressure in saunas is always unpredictable, rising in some people but falling in others, which might be a health risk for some people with blood pressure problems. Saunas generally should not be considered as a therapeutic approach to hyper or hypotension – visit your doctor first. Continue reading …
