The one time you do need to worry about a red face is if you are too hot and are at risk of hyperthermia, which is an extreme elevated body temperature that can be deadly.
To avoid this, Professor Newton says it's important to stay hydrated in the heat and seek medical assistance if you have a headache, dizziness, dry, clammy skin or have stopped sweating.

If you are red-faced after running, you are not alone. This is a common issue, especially in women and people with fair skin. When you're running, your body is producing heat.
Sweating helps cool you down. Your body also increases blood supply to your skin to help regulate your temperature. Your capillaries dilate so more blood can flow through them and radiate extra heat out through your skin.
The diameter of the capillaries in the cheeks is wider than elsewhere, and they are closer to the surface. So, when they dilate, there is more red blood coming close to the surface, giving you that rosy red color. Many runners get red-faced no matter how much their fitness improves in fact, some research shows that endurance athletes get more flushed, earlier in their workouts than less fit people. Everyone handles the heat differently, and just as some runners sweat more than others, some get red faces and others don't.
Some people naturally have more capillaries. Others may have capillaries that naturally carry more blood to the face during exertion. Either way, they are more prone to having a red face from exercise. You may find that you get redder if you're doing an intense run or running in hot or humid weather. But why so red? In an effort to cool you off, your blood vessels and skin pores open, which allow your blood to flow closer to the surface of your skin. This rush of blood to the skin also seems to happen earlier during activity for trained athletes compared to couch potatoes, he says.
When your vessels dilate, the influx of blood can cause the cells in your skin to open and release their contents.
Those contents vary from person to person and may include a type of fatty compound called a prostaglandin, which may contribute to the redness you experience during exercise or during an embarrassed blush , says Dr. Garret FitzGerald, a professor of medicine at the University of Pennsylvania.
In extreme cases, this could even lead to a form of hives, he says. Also, for those with rosacea —a common condition involving hypersensitive blood vessels and an overactive immune system, both of which lead to red or inflamed skin—exercise, alcohol or even spicy food can cause a deep flush, Friedman says. So the amount of facial reddening you experience because of exercise depends on a lot of factors, from your genes to your fitness level.
Should you do anything about it? For people diagnosed with rosacea, there are topical treatments available that can help control the flush, Friedman says. And for others who may have extreme flushing due to the release of histamine, some antihistamine drugs like Cetirizine may help douse the cutaneous flames if you take it before exercising.
