Hydration at Work: A Practical Guide for UAE Employers

Glass filling at an office water dispenser

Hydration at work is one of the cheapest wellbeing measures an employer can put in place, and in the UAE it is also a safety matter. Staff who drink enough through the day keep their attention steadier and feel better. Staff who don’t are more likely to fade by mid-afternoon. For outdoor and high-heat roles, Abu Dhabi’s workplace safety framework asks employers to act. This guide covers the signs of dehydration, how much water people need, what UAE guidance says, and what HR and managers can change this month.

TL;DR

  • The Dubai Health Authority (DHA) gives a simple baseline of 0.033 liters of water per kilogram of body weight per day, with a doctor’s advice needed for people with health conditions.
  • Dark urine, dry mouth, headache, fatigue and dizziness are the signs to teach every team.
  • In Abu Dhabi, the ADOSH-SF heat-stress program covers workplaces where temperatures may reach 35°C or higher. It includes cold potable water, physician-guided electrolyte drinks and programmed drinking every hour where appropriate.
  • Access beats awareness: cold water within reach, personal bottles and manager example change habits more than posters do.
  • Offices need a hydration routine too. Air-conditioned rooms hide thirst, and long meetings and heavy coffee drinking make it worse.

Why hydration at work matters

Water supports temperature regulation, circulation and the brain. When fluid runs low, people notice it first as tiredness or a dull headache, and rarely as thirst. That is why dehydration is so easy to miss in a busy office.

The evidence on thinking is specific. A Penn State study of 78 adults aged 47 to 70 found that mild dehydration reduced sustained attention over a 14-minute task, while other cognitive functions were unaffected. It was a small study of older workers, so treat it as a pointer. It fits what many managers see: the work that suffers first is the work that needs steady focus, such as reviewing a contract, reconciling accounts or handling a client call.

For teams in finance, legal, hospitality and luxury retail, that kind of focus is the job. For teams on site, in logistics or on the road, the stakes go beyond focus. Heat illness is a real risk, and the guidance below treats it as such.

Hydration is also one small part of a wider picture. If your people report fatigue, irritability or poor concentration, water is a sensible first check. It is rarely the whole answer, and it sits alongside workload, sleep and stress. Our guide to what stress in the workplace looks like for UAE HR covers the rest.

Signs of dehydration during the workday

The DHA’s 2025 summer guide lists the indicators to watch for: dark yellow or amber urine, dry mouth, sleepiness, fatigue, extreme thirst, headache, confusion, dizziness and lack of tears.

In an office, the early signs usually look like this:

  • A headache that appears around 2 or 3 p.m. and eases after a break
  • Reading the same paragraph twice
  • Feeling drowsy straight after lunch even with a normal night’s sleep
  • Dry lips and mouth during back-to-back meetings
  • Urine that is darker than pale straw color

On site or outdoors, treat confusion, dizziness or severe fatigue as urgent. Move the person to shade or a cool area, give fluids and get medical attention. Managers should know this before summer, not during it.

Common causes in UAE workplaces

Most causes are ordinary and fixable:

  • Heat and humidity. Even a short walk from car park to building in summer causes fluid loss.
  • Air conditioning. Cold, dry rooms reduce the sense of thirst, so people skip drinking.
  • Meeting-heavy days. People postpone drinking until the next break, and the next break never comes.
  • Coffee instead of water. The DHA notes that tea, coffee, soup, milk and juices all count toward fluid intake, but water is still the best drink for satisfying thirst. Heavy caffeine intake is something the heat-safety framework asks employers to educate staff about for outdoor roles.
  • Long commutes and travel. Executives who fly regularly or spend hours in traffic often start the working day already behind.
  • Fasting. During Ramadan, the pattern of drinking shifts to the evening. Our advice is to review meeting times and workloads rather than leave this to individuals.

How much water should people drink at work?

There is no single number that suits everyone, and a good article should say so. The DHA’s guide offers a practical starting point: 0.033 liters per kilogram of body weight per day. For a 60 kg person that is about 2 liters.

Here is what that looks like for a few body weights:

Body weight Approximate daily fluid need (DHA baseline)
60 kg 2.0 liters
75 kg about 2.5 liters
90 kg about 3.0 liters

The table applies the DHA’s formula directly. It is a baseline for healthy adults, and it counts total fluids, not only water from a bottle.

The DHA is clear that the figure may differ with health conditions, medications, loss of muscle mass, reduced kidney function and other factors. It advises people to consult a doctor to calculate their daily requirement. An employer should therefore never set a universal target for staff. Give the baseline as guidance and tell people with a medical condition to follow their doctor’s advice.

Does coffee count?

Yes, to a degree. According to the DHA, fluid intake can include soup, milk, tea, coffee, soda and juices, although water is the best choice for quenching thirst during high activity. The practical message for staff: coffee is fine, but it should not be the only thing in the cup all day. Sugary sodas and juices add calories without helping much with thirst, so make plain or lightly flavored water the easy default.

What UAE guidance says for employers

Two official sources shape the practical rules.

The midday break

The Ministry of Human Resources and Emiratisation runs an annual midday break policy. Work under the sun and in open places is prohibited from 12:30 p.m. to 3:00 p.m. between 15 June and 15 September each year. It applies to outdoor work only, so it will not affect most office teams. HR leaders at companies with site, delivery or event staff should have rest areas and water ready well before the period begins.

Abu Dhabi’s heat-stress code

The Abu Dhabi Occupational Safety and Health System Framework (ADOSH-SF) has a code of practice on safety in the heat. In summary, it asks employers to:

  • Carry out heat-stress risk assessments and medical surveillance
  • Use the Thermal Work Limit to assess work and rest breaks and water needs
  • Provide fluids, shade or cooling, and access to medical attention
  • Run an effective heat-stress program wherever temperatures may reach 35°C or higher, unless risk assessments and the Thermal Work Limit show no risk
  • Within that program, supply potable water, physician-guided electrolyte drinks and programmed drinking every hour where appropriate

The code also covers educating workers about alcohol, tea, coffee and caffeinated drinks, which can increase susceptibility to heat-related illness. It recommends acclimatization periods for new hires, personal water containers and urine charts so people can check their own status.

This framework applies in Abu Dhabi. If you operate in Dubai or other emirates, check the requirements of your own regulator, and use the Abu Dhabi code as a well-structured model. For how wellbeing duties map to UAE regulators more broadly, see our guide on mapping wellness compliance to regulators.

How to drink water through the workday

The habit matters more than the amount. Large amounts at once are not the aim. For heat-exposed staff, the ADOSH-SF calls for programmed drinking every hour where appropriate, which means scheduled, regular drinks instead of waiting for thirst.

A routine that works for office staff too:

  1. Start the day with a glass before the first coffee.
  2. Keep a bottle on the desk, visible and refilled. What is in sight gets drunk.
  3. Drink at natural anchors: when you sit down, before each meeting, after each call.
  4. Check urine color a couple of times a day. Pale straw means you are fine; dark yellow or amber means drink more.
  5. Space it out. Heavy loading late in the day can disrupt sleep and doesn’t make up for a dry morning.

After intense physical work, the DHA advises drinking more than the fluid lost, spread over two to six hours, to avoid over-hydration. That is useful for site teams after a hot shift and for staff who have just run a long outdoor event.

What employers can do: a checklist for HR

People rarely under-drink because they don’t know water is good for them. They under-drink because water is inconvenient. The ADOSH-SF suggests providing readily accessible cold potable water, electrolyte-replacement drinks as a physician advises and shaded cooling areas. Here is how that translates into any UAE workplace.

In the office

  • Place chilled water points on every floor and near meeting rooms, not only in the pantry.
  • Give new joiners a reusable bottle in the welcome pack.
  • Put water and glasses in every meeting room, and let people drink during calls.
  • Offer flavored water or herbal tea alongside coffee, and check the workplace nutrition guidelines your team uses so drinks policy matches food policy.
  • Build short breaks into long workshops and trainings.

For outdoor, site and client-facing roles

  • Run a documented heat-stress risk assessment before summer.
  • Provide cold water at every work location and a cooled rest space.
  • Schedule regular drinking breaks, and agree rules for stopping work.
  • Brief supervisors on the signs of heat illness and on who to call.
  • Plan acclimatization for new hires and for returning staff.
  • Offer electrolyte drinks only as a qualified physician advises.

For managers

Managers set the habit. If a leader drinks water in meetings and schedules a pause in a two-hour session, the team follows. Our workplace wellbeing tips for managers cover how to do this without turning it into another task.

Make it a team habit

Simple, low-pressure formats work best: a shared team goal for bottle refills, a reminder in the weekly stand-up, or a hydration prompt on your intranet. Avoid anything that shames individuals, and keep health information private. If you want an incentive structure, process-based incentives that reward participation rather than outcomes are the safer design, and our guide to wellness incentives for employees explains how.

Our perspective on hydration at work

When we work with UAE organizations, hydration rarely appears on the brief. HR leaders come to us about burnout, low energy in the afternoons, or absenteeism. When we look at the day those people actually have, back-to-back meetings, strong coffee, cold air conditioning and little reason to leave the desk, water is often the first thing to slip.

We treat hydration as part of energy management, not as a stand-alone campaign. A poster cannot fix it. What fixes it is a working day designed so that drinking is easy: water within reach, breaks that really happen and leaders who model the behavior. We also think the framing matters. People respond better to “here is how to feel sharper at 3 p.m.” than to a list of rules.

We would also keep expectations honest. Water will not cure a heavy workload or chronic stress. It is a foundation, one pillar in a wider approach that includes sleep, movement, nutrition, mental health support and resilience. Employers who build on that foundation, and measure how staff feel over time, get lasting change instead of a one-week awareness push.

FAQ

How much water should I drink at work?

The DHA gives a baseline of 0.033 liters per kilogram of body weight per day, which is about 2 liters for a 60 kg adult. That covers all fluids across the day, not just the office hours. The figure can differ with medical conditions, medications or kidney function, so ask your doctor if any of these apply to you.

What are the signs of dehydration at work?

Watch for dark yellow or amber urine, dry mouth, headache, fatigue, sleepiness, dizziness and confusion. In an office, a mid-afternoon headache or trouble concentrating is often the first sign. Confusion or dizziness, especially in hot conditions, needs prompt attention and medical help.

Does coffee count toward hydration?

Partly. The DHA lists coffee and tea among the drinks that contribute to fluid intake, but water remains the best for thirst. For staff in hot conditions, Abu Dhabi’s heat-safety code asks employers to educate workers about caffeinated drinks. A sensible habit is to match each coffee with a glass of water.

Do UAE employers have to provide drinking water?

In Abu Dhabi, the ADOSH-SF heat-stress program requires potable water where temperatures may reach 35°C or higher, unless risk assessments show no risk. Rules differ by emirate and sector, so check with your own regulator. Whatever the legal minimum, free cold water in every workplace is simple and inexpensive.

How can I get my team to drink more water?

Make it easy before you make it a message. Put water points near desks and meeting rooms, give everyone a bottle and have managers drink openly in meetings. Reminders and scheduled breaks help more than targets, and nobody should be pressured about their intake.
