What Happens When You Get Sick?

From Kurzgesagt, an accessible explanation of what happens to the human body when you get sick.

Your brain activates sickness behavior and reorganizes your body’s priorities to defense. The first thing you notice is that your energy level drops and you get sleepy. You feel apathetic, often anxious or down and you lose your appetite. Your sensitivity to pain is heightened and you seek out rest. All of this serves to save your energy and reroute it into your immune response.

They also reveal the best way to boost your immune system to protect yourself against disease. I don’t want to spoil it but it’s vaccines. Vaccines are one of the best things humans have ever invented.
