Why does glandular fever cause night sweats?

During a viral illness, the body's temperature set point can rise and fall. When it falls, the body may release heat through sweating, which is often more noticeable under bedding at night. Night Sweats is a common presentation of Glandular Fever. Night sweats can also be caused by a warm room, medicines, hormonal changes and other illnesses, so they do not identify one cause on their own.

You may wake with damp nightclothes or bedding and feel chilled afterwards. Fever, sore throat, swollen glands and fatigue may occur at the same time.

Keep water within reach and replace fluids through the day. Use light, breathable sleepwear and layers of bedding that are easy to remove. Keep the bedroom comfortably cool without making yourself shiver. Change damp clothing if needed so you can settle back to sleep.

Write down when the sweats occur, whether you have measured fever, and any new symptoms. This detail can help a clinician decide whether the pattern fits an infection or needs another assessment.

Seek urgent medical care for difficulty breathing or swallowing, severe upper-left abdominal pain, fainting, confusion, or yellowing of the skin or eyes. Arrange prompt review if night sweats are drenching and ongoing, you have persistent fever, are losing the ability to drink or eat, or develop new worrying symptoms such as a spreading rash or severe weakness.

Ask whether your night sweats fit glandular fever, how to manage fever safely, and which symptoms would change the plan. Ask whether your current medicines could be contributing to sweating and when follow-up is needed.
