Should I Shower With Hot Or Cold Water When Sick?

When It Makes Sense

• Good fit: If you have mild chills, muscle aches, or a congested nose, a warm shower (around 100‑105°F / 38‑40°C) can help relax muscles, open nasal passages, and make you feel more comfortable.
• Good fit: When you have a high fever (above 102°F / 38.9°C) and feel overheated, a cool‑to‑lukewarm shower (around 80‑90°F / 27‑32°C) can safely lower body temperature without causing a sudden shock.

When You Should Avoid It

• Warning sign: If you have a respiratory condition such as asthma that is triggered by steam or sudden temperature changes, a hot shower may exacerbate bronchospasm and should be avoided.
• Warning sign: When you feel dizzy, weak, or have a low blood pressure reading, stepping into a very hot or very cold shower can increase the risk of fainting; in this case, a brief tepid rinse is safer.

Pros and Cons

Pros

• Warm water can improve circulation, ease muscle tension, and temporarily relieve congestion, making it easier to breathe.
• Cool water can help lower an elevated core temperature, reduce sweating, and provide a refreshing sensation that may improve mood.

Cons

• Hot showers may raise your core temperature further, potentially worsening a fever or causing dehydration if you stay too long.
• Cold showers can cause shivering, which actually raises internal heat production, and may be uncomfortable for someone already feeling chilled.

Decision Checklist

• Is your body temperature elevated (fever) or are you feeling primarily cold and shivery?
• Do you have any respiratory or cardiovascular conditions that are sensitive to steam or rapid temperature shifts?
• Are you feeling stable enough (no dizziness or weakness) to safely stand in a shower of your chosen temperature?

Alternatives to Consider

If you are uncertain about water temperature, a tepid (lukewarm) shower—around 90‑95°F (32‑35°C)—offers a middle ground that can provide comfort without extreme temperature effects. Additionally, using a humidifier, applying warm compresses to the sinuses, or taking a sit‑z‑up bath can address congestion and fever without the risks associated with very hot or very cold showers.

Final Recommendation

When sick, choose the shower temperature that aligns with your primary symptoms: warm water for chills, aches, and congestion; cool water for high fever and overheating. Always monitor how you feel during the shower, keep the duration short (5‑10 minutes), and stay hydrated. If you have chronic health issues, experience severe symptoms, or feel uncertain, consult a healthcare professional before deciding.
