For many people, Summer is a chance to enjoy the warm weather outdoors. However, for those living with dementia, the rising temperatures bring unique challenges, such as the increased risk of dehydration. People with dementia often face difficulties in communicating their needs, including thirst, making it crucial for caregivers and loved ones to be vigilant in ensuring adequate hydration. If you have a loved one with dementia, here are some of the reasons behind the susceptibility of individuals with dementia to dehydration in hot weather and some practical tips to prevent this potentially serious health concern.

The link between dementia and dehydration

People with dementia are more prone to dehydration for various reasons. Memory loss and cognitive decline can impact an individual’s ability to recognize and respond to thirst cues. Additionally, individuals with dementia may have difficulty expressing their needs or may forget to drink water regularly. The ageing process itself can diminish the sense of thirst, further complicating the situation.

Medications commonly prescribed for dementia, coupled with the ageing body’s reduced ability to conserve water, can contribute to an increased risk of dehydration. Moreover, certain behaviours associated with dementia, such as wandering and restlessness, can lead to heightened physical activity and, subsequently, more significant fluid loss.

How to recognise dehydration

Recognising dehydration, especially in individuals with dementia, requires a keen eye for subtle cues and an understanding of their unique challenges in communicating their needs.

  • One key indicator is a change in behaviour; increased confusion, irritability, or restlessness can signal dehydration.
  • Physical signs such as dry mouth, sunken eyes, or dark yellow urine may also be indicative.
  • Keep an eye on the frequency of bathroom visits, as infrequent urination can be a red flag.
  • Monitoring weight loss, as sudden drops may suggest fluid loss, is another valuable metric.
  • Pay attention to skin turgor—if the skin on the back of the hand doesn’t bounce back quickly when pinched, it may signify dehydration.

Regularly checking these subtle yet critical signs can aid caregivers and loved ones identify dehydration early, allowing for prompt intervention to ensure the well-being of those under their care.

Tips to prevent dehydration in individuals with dementia

Create a Hydration Schedule: Establishing a routine for regular fluid intake is crucial. Set specific times for offering water, perhaps aligning with meals or daily activities. Consistency helps individuals with dementia anticipate and accept the routine.

Offer a Variety of Beverages: Beyond water, consider providing hydrating alternatives such as herbal teas, diluted fruit juices, and electrolyte-rich drinks. Experiment with different temperatures and flavours to cater to individual preferences.

Use Visual Cues: Place visible reminders around the living space, such as large and colourful water bottles. Visual cues can prompt individuals with dementia to drink, compensating for potential difficulties in verbal communication.

Monitor Weather Conditions: Stay informed about weather forecasts, especially during hot spells. Adjust daily routines accordingly, planning more indoor activities during peak temperatures and ensuring access to shaded areas when outdoors.

Encourage Hydration through Foods: Incorporate water-rich foods, such as watermelon, cucumbers, and soups, into meals. This can supplement fluid intake and provide additional nutrients.

Create a Comfortable Environment: Ensure living spaces are adequately cooled and well-ventilated. Individuals with dementia may be less likely to drink if they feel uncomfortably warm.

Engage in Hydration Activities: Transform the act of drinking water into a social or enjoyable activity. Share a refreshing beverage during a pleasant conversation or while engaging in a favourite hobby.

In the scorching heat of summer, safeguarding the well-being of individuals with dementia requires a proactive and understanding approach. By recognising their unique challenges and implementing practical strategies to promote hydration, caregivers and loved ones can contribute significantly to the overall health and quality of life of those navigating the complexities of dementia. Through these efforts, we can strive to ensure that the season’s warmth brings joy without compromising the health of those we hold dear.
