Can a fever be the result of insomnia?

While insomnia itself does not directly cause a fever, the stress and strain on the body from prolonged lack of sleep can weaken the immune system, making one more susceptible to infections that might cause a fever. Additionally, certain underlying conditions that contribute to insomnia, such as infections or inflammatory disorders, could also lead to a fever. Therefore, while insomnia can be related to fever indirectly, it is not a direct cause.
