Nausea (1) is an unsettling sensation in the stomach that often precedes vomiting. It involves complex interactions between the nervous system and the gastrointestinal tract. While commonly linked to infections or food poisoning, insufficient sleep can also trigger or worsen nausea.
How Sleep Deprivation Can Lead to Nausea
Lack of sleep disrupts the body’s natural balance, contributing to several physiological effects that can result in nausea.
- Hormonal Imbalances: Sleep deprivation increases cortisol (the stress hormone) (2) and reduces serotonin, affecting digestion and contributing to queasiness.
- Nervous System Dysregulation: Poor sleep overstimulates the autonomic nervous system (3), leading to symptoms like dizziness, nausea, and indigestion.
- Weakened Immune System: A compromised immune response can exacerbate gastrointestinal distress (4) and heighten nausea risk.
Outside Triggers Linking Sleep Deprivation and Nausea
Inadequate sleep can amplify external factors that worsen nausea:
- Increased Stress and Anxiety: Poor sleep fuels stress, which is closely linked to gastrointestinal symptoms (4)(5).
- Medication Side Effects: Some medications, particularly those affecting the central nervous system, may cause nausea when combined with sleep deprivation.
- Dehydration: Lack of restorative sleep can reduce hydration levels, contributing to dizziness and nausea (6).
