4. Chronic Fatigue
Sleep is one of the most important things that keep us alive and well. If you sleep at least 8 hours every night and still feel very tired during the day then this might be a sign of a disease, infection, or simply, a weak immune system.
For example, there are a few autoimmune diseases (Multiple sclerosis or Lupus) that can cause chronic fatigue due to the immune system attacking healthy cells and tissues in the body. Being tired all the time, without a solid motive, can indicate a health problem.
On top of that, a lot of stress can also lead to a weak immune system which will eventually lead, to a more serious problem. If you are experiencing chronic fatigue, you should talk to a doctor to determine the basic cause and get a treatment plan.
