Yes, you can feel sick when tired.
Many people experience unpleasant symptoms, including nausea, when they are sleep-deprived. This feeling of sickness can sometimes be accompanied by other gastrointestinal issues, such as gas, stomach pain, and diarrhea.
Why Does Tiredness Cause Sickness?
While the exact mechanisms aren't fully understood, several factors likely contribute to feeling sick when tired:
- Hormonal Imbalances: Sleep deprivation can disrupt the balance of hormones in the body, including those that regulate appetite and digestion. This disruption can lead to nausea and other digestive problems.
- Weakened Immune System: Lack of sleep weakens the immune system, making you more susceptible to infections that can cause nausea and vomiting.
- Stress Response: Being tired can trigger the body's stress response, leading to the release of stress hormones like cortisol. These hormones can affect the digestive system and contribute to feelings of nausea.
- Vagus Nerve Stimulation: The vagus nerve connects the brain to the digestive system. Sleep deprivation can sometimes overstimulate this nerve, leading to nausea.

How to Relieve Symptoms
If you are feeling sick due to tiredness, consider the following:

- Eat Bland Foods: Opt for easily digestible foods like toast, crackers, or bananas.
- Rest: Avoid strenuous activities and allow your body to recover.
- Over-the-counter remedies: Consider using over-the-counter remedies for nausea, such as antiemetics, if symptoms persist.
- Consult a Doctor: If your symptoms are severe or persistent, consult a doctor to rule out any underlying medical conditions.
