Sweating, including night sweats, can be a symptom experienced by individuals with COVID-19. This occurrence is often part of the body’s natural immune response as it works to combat the infection.
Sweating and COVID-19
This symptom can range from mild dampness to significant discomfort, sometimes soaking clothes and bedding. Importantly, this perspiration can occur even in the absence of a high fever, indicating other factors may be at play.
Night sweats, a common feature in various viral infections, can be an early symptom of COVID-19 for some, even preceding a fever. These episodes can be particularly intense, disrupting sleep and contributing to fatigue. While fever is a well-known cause of sweating, it is clear that sweating can also be an independent symptom in COVID-19 cases.
Why COVID-19 Can Cause Sweating
When fighting an infection, the immune system releases chemicals called pyrogens, which signal the brain to raise the body’s internal temperature, resulting in a fever. Sweating then serves as the body’s mechanism to cool itself down and regulate this elevated temperature. This process helps the body return to a safer temperature range.
Beyond fever, the virus can also affect the autonomic nervous system, which controls involuntary bodily functions like sweating and temperature regulation. Inflammation and immune activation associated with COVID-19 can influence signals through this system, contributing to excessive sweating even without a high fever. This autonomic dysfunction can sometimes persist even after the acute phase of the illness, leading to ongoing sweating.
When to Consult a Doctor
You should contact a healthcare provider if sweating is severe or persistent, especially if accompanied by a very high temperature that lasts five days or more or does not respond to paracetamol. Other concerning symptoms include difficulty breathing, persistent chest pain or pressure, new confusion, or an inability to wake up or stay awake.
It is also advisable to seek medical evaluation if symptoms worsen, are not improving, or if you have underlying health conditions that place you at higher risk for severe illness. For children, a high temperature of 38°C or higher for those under 3 months, or 39°C or higher for those 3 to 6 months old, warrants prompt medical consultation. Any unusual or severe symptoms should prompt a call to your medical provider.
Managing Sweating While Ill
Managing sweating during illness focuses on comfort and supportive care. Staying well-hydrated is important to replace fluids and electrolytes lost through perspiration, which also helps regulate body temperature. Drinking plenty of water or electrolyte-rich drinks is beneficial, especially if you are experiencing fever, vomiting, or diarrhea.
Wearing loose-fitting clothing made from breathable fabrics like cotton can help keep you cooler and allow sweat to evaporate more easily. Using cool compresses and maintaining a comfortable room temperature can also provide relief. Changing bedding and clothing as needed helps maintain hygiene and comfort when dealing with night sweats.
