Asthma feels better on holiday: how to log workdays, days off and holidays for your appointment

You sleep better on holiday, and back in the work week the cough, tight chest or breathlessness return after work. Many people with asthma know this pattern. By itself it proves little: whether work plays a part is for a doctor or nurse to assess. What helps them is the course you track day by day, on workdays, days off and holidays. You can keep it on paper or in the asthma diary in Sam, where reliever uses are logged apart from your preventer schedule.

This is general information, not a diagnosis. If you only suspect asthma, your doctor is the next step.

Why you often feel better on holiday

On holiday you may notice that you reach for your reliever less and sleep better. There can be many reasons: less stress, more sleep, fresher air, no commute and no contact with substances at work. Feeling better on holiday alone is not proof that work is the cause.

What lies behind it is clarified by a doctor or nurse with lung function tests and your documented history. Your part is the course you keep.

Occupational and work-aggravated asthma are not the same

Doctors distinguish two cases that are easy to confuse. Asthma and Lung UK describes them clearly. Occupational asthma is caused by breathing in substances at work. Work-aggravated asthma means that asthma you already have gets worse at work.

Only a doctor or nurse decides which category applies to you, or whether either does. Your diary supplies the material for that conversation. It does not supply the category.

How much work exposure may contribute

Respiratory societies have looked at how often work exposures play a role in adult asthma. The American Thoracic Society and European Respiratory Society 2019 statement estimated an occupational contribution of about 16% for asthma in adults. An older American Thoracic Society statement from 2003 put the median around 15%.

These are population estimates, not a verdict on your case. What matters for you is what your own record and your doctor's tests show.

What you record for your GP and lung team

To make the course comparable, you note the same few facts for each day:

• Which symptoms you had and at what time.
• When you used your reliever and how many puffs.
• Whether you woke at night because of symptoms.
• And as the key marker: workday, day off or holiday.

The last item is the core. Only marking the day type makes workdays comparable with days off and holidays. From memory this difference blurs after two weeks. A daily entry keeps it.

How to keep workdays, days off and holidays separate

You need no long diary. What matters is regularity and the marking. When you make an entry in Sam, you enter symptoms, reliever and nights. Whether it was a workday, a day off or a holiday you keep beside it, for example in your calendar. Over weeks the same facts sit side by side, and you can lay both out at the appointment. A guide to keeping a symptom diary lives in the symptom diary in Sam.

What your diary shows and what it does not

A diary shows a pattern. It does not say what the pattern means. If you use more reliever on workdays than on holiday, that is a course you can present. Whether work, stress, less sleep in the week or something else lies behind it, your care team assesses. That assessment needs lung function tests, for example measurements over time. What the course means for your asthma control is explained in asthma not well controlled: what that means. New to the diagnosis? Start with asthma diagnosis: your first weeks.

When an asthma attack is an emergency

A severe asthma attack is a medical emergency. The NHS says to call 999 if you are having an asthma attack and you start to feel worse at any time, do not feel better after the maximum dose of your reliever, or do not have an inhaler. Use your local emergency number (112 in the EU, 999 in the UK, 911 in the US). Do not wait. How you act when symptoms get worse belongs in your written asthma action plan. If you have no plan, ask your practice for one.

Record your asthma in Sam and take workdays and holidays with you

You go to the appointment with a course and your calendar beside it, instead of trying to describe weeks from memory.

• Instead of loose notes: you enter symptoms, reliever uses and nights in the asthma program, your diary with a doctor report. Workdays, days off and holidays you lay out from your calendar at the appointment.
• Instead of your own summary: the doctor report (PDF) sums up the period you choose, including the days you used your reliever and the nights you were woken.
• Instead of guessing: sleep and respiratory rate from Apple Health sit beside your entries when data exists.

Sam does not decide whether your symptoms are work-related. That is for your doctor, nurse or occupational health team. Sam records what you enter.
