A virus causes a higher-than-normal body temperature, which is known as viral fever. Runny nose, coughing, nausea, exhaustion, and body aches are some of the symptoms that a person may suffer.
Our body is stimulated to generate stress hormones when we experience stress, which causes a ‘flight or battle’ response and activates our immune system. This reaction allows us to respond to dangerous situations quickly. This stress response may often be a suitable, or even beneficial, reaction.
Stress can make skin problems worse as well. Stress can aggravate psoriasis, rosacea, and eczema, for instance. It can also induce hives and other forms of skin rashes and cause fever blisters to flare up.
