Night Worker
Medicals
Under the Working Time Regulations, night workers must be offered a free night worker health assessment at regular intervals.
A night worker medical assessment is typically recommended required for individuals who are regularly engaged in night shift work or other forms of shift work that involve working during the night time hours or irregular schedules. This assessment is designed to evaluate the potential health risks and impacts associated with working outside the body's natural circadian rhythm.
Why night worker medicals are important

Night worker medicals are a crucial part of the safe and responsible employment of night shift team members. Long-term night shift work has been linked to several health problems, including heart disease, ulcers, metabolic problems, obesity and certain cancers. A lack of sleep can alter the metabolism and the appetite, and encourage irregular eating habits, which can raise the risk of metabolic issues. Working night shifts disrupts the body’s circadian rhythms, and this can disrupt normal behaviour cycles and lead to increased incidence of depression and stress.
What's included in a night worker medical
A night worker health assessment includes examinations of:

General health questionnaire (Weight, height, BMI, blood pressure, cholesterol monitoring)
Musculoskeletal (Assessment of joint and muscle health)
Previous medical history questionnaire (Current medications and existing conditions)
What we look for in Night Worker Medicals
Other medical conditions requiring regular medication on a strict timetable
During a night worker medical, we will consider any health conditions you have and medications you regularly take, reviewing whether night work will may interfere with how your medication works or whether it causes drowsiness.
Chronic chest disorders
Chest disorders such as asthma or COPD can worsen when working nights. In a night worker medical, we will check whether irregular working hours worsen your symptoms.
Medical conditions affecting sleep
For those who suffer from sleep disorders such as insomnia or sleep apnoea, the night worker medical assessment will check whether working at night could negatively impact your sleep schedule.
Stomach or intestinal disorders
Working at night can understandably disrupt how your body works, so gastrointestinal issues such as acid reflux and IBS can worsen. The night worker medical will take this into account.
Diabetes
Employees who have diabetes could also face difficulties when working late at night, as an irregular body clock could affect blood sugar control. We will assess how you manage any blood sugar issues and offer recommendations.
Heart and circulatory disorders
Heart and circulatory disorders require extra care when working nights, so it's important to have a night worker medical to see whether night work increases risk.

Night Worker Medical FAQs
Do night workers have to have a medical?
Yes, night workers have to have a medical under the Working Time Regulations. This is because working at night over an extended period can negatively affect your physical and mental health. Employees must offer regular assessments for those who already work nights, and a health assessment for those who are to begin working nights, to ensure they are fit and well enough to do so. Book a night worker medical with us to ensure your company is operating in line with health regulations.
