why am i always sick

The main reasons a person might always feel sick or get sick frequently include a weakened or compromised immune system, chronic stress, lack of sleep, poor diet, chronic health conditions, exposure to infections, obesity, alcohol use, and environmental factors. Some people may also have genetic factors that make their immune system less effective. Chronic stress raises cortisol levels and suppresses immune cell function, making frequent illness more likely. Sleep deprivation and poor nutrition can also weaken the body's defenses. Environmental exposures like pollution or close contact with people increase the chance of infection. Additionally, age and certain chronic disorders can reduce immune function, leading to recurrent sickness. If someone frequently feels sick, it is advisable to consult a doctor to rule out immune disorders or other underlying health problems. Improving sleep, nutrition, stress management, and hygiene may help reduce illness frequency.
