Why not to jog when you are sick
Ignoring the symptoms of a cold can be life threatening.
Too often, people ignore the symptoms of a cold, convincing themselves they can ‘push through’ and fight the illness by staying active.
But sports medicine expert Dr Maki Ramagole warns that even a short burst of mild exercise can have real risks for the cold patient.
“An annoying cough goes beyond the irritation of a tickle in the throat and can leave you feeling exhausted and lethargic. But trying to maintain a routine and continuing with a busy schedule when falling ill can have harmful long-term effects – particularly if this includes exercise.
“What we too often forget is that a cough is an indication that we’re not well. When we exercise, our lungs have to expand to increase oxygen intake. If we have a cough, our lungs aren’t able to do this,” explained Ramagole. “Our body also uses up more energy trying to fight off infection when we’re sick. If we exercise while ill, our body’s energy levels are depleted and we won’t be able to recover as efficiently.”
Real risks
Ramagole said that the dangers of exercising when ill include the risk of myocarditis [inflammation of the heart muscles], which can be life threatening. “Congestion of the lungs can also lead to oedema [build-up of fluid] in the lungs. This can be the case for mountaineers climbing at high altitudes – the fluid collection means the lungs can’t get enough oxygen into the body. If not addressed immediately with medical attention, this can also be life threatening.
“Contrary to popular belief, the notion of ‘sweating out a cold’ is wholly untrue. In fact, exercising with a fever can have catastrophic effects on the body. The ‘neck rule’ [symptoms either above or below the neck] does hold some truth. If you have ‘head flu’ (a runny nose and mild congestion without a cough or fever), mild exercise is still safe. If the infection is in the lungs, with or without a fever, exercise is not advised.”
How soon is too soon?
Anyone recovering from a cough or flu should take caution in resuming any kind of intense exercise. She advises the three-day rule when it comes to any illness with a fever: you need to be fever-free for three days before you exercise again.”
Ramagole advised to give yourself time to heal – see a medical professional for an accurate diagnosis, then rest and drink lots of fluids. “Only when you’re feeling completely better, start with mild exercise, like a gentle walk.
“But pay attention to how you’re feeling and skip exercise if your body says so. If you feel any nausea, dizziness, shortness of breath or weakness, stop immediately.”
