For Adult Patients: What to do when you have a high temperature or feel unusually cold (video)

What to do when you have a high temperature or feel unusually cold – for adults.

Additional Information

This video has been created by Paramedics in response to the number of patients we are coming across who are unsure what to do when they have a high temperature or don’t know that the signs and symptoms they are experiencing may mean that they have a high temperature.

If this sounds like you, don’t worry, you’re not alone:

42% of working-age adults are unable to understand and make use of everyday health information, rising to 61% when numeracy skills are also required for comprehension

Public Health England (2015)

As Paramedics, we are frequently advising patients to take paracetamol if they are in pain – unless they have been specifically told not to. We are also advising patients to take off excess layers when they have high temperatures, even if they feel cold. I hope the video is helpful and informative. If there are any concerns, please let me know in the comment box below.

I am a patient/member of the public. Can I contact you for medical advice?

Sadly, due to a whole combination of grey area legalities, I’m unable to offer direct medical advice, and these requests will not be responded to.

I am an HCP and I have a question or suggestion.

No worries, go ahead and contact me.

Is there anything else I should be aware of?

Yes. Please read our disclaimer and the accompanying information below.

Additional Information

When do I need to call 999 or attend A&E for a high temperature alone?

  • If you have signs of SEPSIS.
  • If you have signs of MENINGITIS.
  • If you are a chemotherapy patient and you have had recent chemotherapy.
  • If you have new signs of other conditions, such as difficulty breathing, chest pain, or sudden weaknesses (signs of strokes).
  • If you do not have any of the above but you think you need to seek help. Your options are: 111, 999, self-transport to A&E, GPs, or urgent care centres.

How do I take my temperature?

The NHS has some useful information about this here.

Do I need to have an ear thermometer?

This is a question of much debate. In the link above, the NHS advises not using forehead strip thermometers due to lack of accuracy. advises a blanket avoidance of forehead thermometers. Elsewhere on NHS sites, you’re advised that you don’t need a thermometer to work out if you have a temperature – you’ll likely feel hot to touch.

Is a temperature 37.8 or 38?

This is also a subject of much debate. In the NHS, here says 38C. As does here – in adults. NHS Scotland says 37.8. I have chosen the lower threshold.
