Functional health assessments are used to evaluate a patient's physical and mental capacity to perform day-to-day activities, including working, eating, and sleeping. These assessments collect data on basic tasks such as hygiene, elimination, eating, and mobility, as well as more complex tasks like managing finances and household chores. The goal is to understand the patient's functional limitations and develop interventions to improve their independence and quality of life. Sleep, in particular, is critical to immune, neurological, and hormonal function, and sleep disorders can induce addictive behaviours. Open-ended interviews and observations are often used to design personalised treatments and set function-oriented goals.

What You'll Learn
Sleep and rest
Sleep is a critical component of functional health assessments, impacting both physical and mental capacity in day-to-day life. It is a physiological requirement, as indicated by Maslow's hierarchy of needs, and plays a significant role in maintaining overall health and well-being.
The amount of sleep needed varies from person to person, but most adults require 7-9 hours of sleep per night. However, some individuals may need as little as 5.5 hours or as many as 9 hours. Sleeping more than your body needs can also lead to feeling tired. It is important to prioritize sleep and create a healthy sleep routine. This includes maintaining a consistent sleep schedule, even on weekends, and establishing a relaxing bedtime ritual. Avoiding blue light from electronic devices and exposure to bright lights before bed can help improve sleep quality by increasing melatonin production.
To improve sleep hygiene and the bedroom environment, it is recommended to keep the room dark, quiet, and slightly cool, minimizing any clutter. Additionally, it is beneficial to avoid stimulating activities before bed, such as watching TV or using a computer, as these can activate and wake up the brain. Instead, one can practice meditation or relaxation techniques to prepare the mind and body for sleep. Having a light, healthy snack before bedtime, such as oatmeal or a brown rice cake, can also promote better sleep as carbohydrates increase serotonin, enhancing sleep quality.
Sleep disorders and disturbances are common and can be caused by various factors, including stress, environmental noise, discomfort, and pain. It is important to address sleep problems as they can have detrimental effects on health, including increased risk of heart disease, kidney disease, high blood pressure, diabetes, stroke, and a weakened immune system. Functional health assessments should include questions about sleep to identify potential issues and provide personalized treatments or interventions.
In addition to sleep, rest is an important component of overall well-being. Finding a balance between a fulfilling life and prioritizing rest is crucial. Taking a break from daily stressors and practicing mindfulness can help restore balance and improve mental and emotional health. Napping, or "biphasic sleep," is common in many cultures and can provide a short-term boost in alertness and performance. However, napping does not provide the same restorative benefits as nighttime sleep and can disrupt the body's sleep-wake rhythm if not careful.

Eating and nutrition
Functional health assessments consider an individual's capacity to perform basic tasks, such as eating and preparing meals. This includes evaluating their physical and mental ability to feed themselves and manage their dietary needs. For example, a patient with thiamine deficiency may develop Korsakoff psychosis, impacting their mental capacity to maintain a healthy nutritional status.
Nutritional risk screening tools are essential to identify individuals at risk of malnutrition or who are already malnourished. This screening should include dynamic parameters such as recent weight loss, current BMI, recent food intake, and disease severity. Early identification is crucial as malnutrition negatively affects clinical outcomes, quality of life, body function, and autonomy.
Additionally, dietary assessment methods provide valuable data on food and nutrient intakes, as well as insights into eating patterns and behaviours. This information can support health promotion and disease prevention. For instance, certain nutritional deficiencies can cause specific symptoms, such as vitamin A or E deficiencies leading to dry hair, or carotenoid consumption resulting in yellow-orange skin discolouration.
Furthermore, functional nutrition tools that consider sleep and digestive health, in addition to dietary intake, can provide a more holistic understanding of an individual's health. Sleep quality, for instance, can impact weight loss resistance and induce addictive behaviours, while digestive health, as assessed through the Food, Mood, Poop Journal, can provide important diagnostic clues.

Working and employment
Functional assessments are a valuable tool for employers and employees alike. They are used to determine an individual's ability to perform the tasks required by a specific job role and can be conducted as part of a pre-employment screening process or when an existing employee is moving roles or returning to work after an injury or illness.
A Functional Capacity Assessment (FCA) or Evaluation (FCE) typically includes tests of strength, endurance/sustained physical activity, flexibility, balance, fine motor skills, and cardiovascular fitness. The FCA/FCE can last up to four hours and is often used to determine an employee's physical ability to return to work after an injury or illness. This can be done in conjunction with a pre-employment medical assessment, providing objective information to match a worker to a suitable task or role.
For example, a patient who has undergone physical therapy for a traumatic or repetitive motion injury may need to undergo an FCE to determine if they can return to their previous job. The FCE can result in a "yes or no" answer or indicate that accommodations can be made to allow a return to work in some capacity. The FCA/FCE can also be used as part of the recruitment process to assess a candidate's physical suitability for a role and identify those at risk of injury or aggravation of a pre-existing condition.
A job task analysis (or physical demands assessment) is often conducted as part of the FCA/FCE. This involves a detailed examination of the skills and physical demands specific to a particular task or duty. This analysis can be completed through a worksite assessment or a review of the usual duties of a certain occupation, and it helps assessors understand the inherent requirements of the role.
In addition to physical health, mental health and psychosocial factors are also important considerations when assessing an individual's fitness for work. Emotional support and mental health resources can play a crucial role in an employee's transition back to work, helping to reduce the risk of further injury or exacerbation of symptoms.

Self-care and hygiene
Good personal hygiene is important for physical and mental health. It involves keeping all parts of the external body clean and healthy. Maintaining good personal hygiene is essential to prevent the spread of diseases to others.
Good hygiene practices during menstruation can help maintain good health. Wash your hands before and after using the bathroom, and before and after changing a tampon, pad, or menstrual cup. Wrap used disposable menstrual products in toilet paper and place them in a trash bin. Do not flush menstrual products down the toilet.
Dental hygiene involves more than just having white teeth. A good dental hygiene routine can help prevent issues such as gum disease and cavities. Brush your teeth twice a day with a soft toothbrush and fluoride toothpaste. Brush for at least two minutes, making sure to reach all surfaces of the teeth. Use dental floss or interdental brushes to clean between the teeth. Using mouthwash after brushing can help reduce the risk of decay and gum disease.
Personal hygiene in the workplace is also important. Shower or bathe daily and use soap or body wash to ensure you are clean and to remove germs from your body. After washing, apply deodorant to prevent body odours from developing. Wash your hands after using the toilet and regularly throughout the day.
In some cases, the inability to maintain a hygiene routine could result from depression. Depressive symptoms, such as reduced energy levels and impaired cognitive function, can make a self-care regimen more difficult to keep up. Poor hygiene can lead to isolation and loneliness as people may avoid those with poor personal hygiene.

Frequently asked questions
A functional health assessment collects data related to a patient’s physical and mental capacity to participate in Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). ADLs include basic tasks such as hygiene, elimination, dressing, eating, and moving, while IADLs refer to more complex activities that allow patients to function independently, such as managing finances, preparing meals, and taking medication.
Sleep is critical to a person's health as it supports immune, neurological, and hormonal function, as well as detoxification. Sleep issues can induce addictive behaviours as a person may turn to substances to stay energised. Sleep is also one of the biggest factors in weight loss resistance. Therefore, it is important to assess sleep patterns and routines to improve rest, especially in older adults where disruptions in sleep patterns can be particularly troublesome.
Eating is assessed through the patient's food and fluid intake, usual diet, financial ability to purchase food, time and knowledge to prepare meals, and appetite. This is also an opportunity to discuss healthy eating and address signs of malnutrition or obesity.
