Dehydration in This Heat: Symptoms, Risks, and Prevention in Ghana
Ho is hot. Whether you’re in traffic in Ho, working outdoors, fasting, or just going about your day, Ghana’s heat and humidity cause you to lose water fast through sweat. When you lose more fluid than you drink, you become dehydrated — and your body cannot function properly.
Dehydration is not just about feeling thirsty. Even losing 1-2% of your body water can cause headaches, fatigue, poor concentration, and dizziness. Severe dehydration can lead to kidney stones, heatstroke, seizures, and low blood pressure shock.
At Citi Pharmacy, we see cases rise every dry season and harmattan. Here’s what you need to know.
Symptoms of Dehydration: How to Tell You Are Dehydrated
Dehydration sneaks up on you. Thirst actually starts at about 2% dehydration, so don’t wait to feel thirsty.
Early to Moderate Symptoms (Adults):
– Thirst and dry mouth
– Dark yellow, strong-smelling urine and urinating less often
– Headache, dizziness, lightheadedness when standing
– Fatigue, unusual tiredness, poor concentration
– Dry skin — skin that stays pinched (poor skin turgor)
– Muscle cramps, especially in legs and abdomen
– Bad breath due to less saliva production
In Children and Babies — Watch For:
– Dry tongue and lips, no tears when crying
– Sunken eyes and sunken soft spot on head (fontanelle)
– Cool, blotchy hands and feet
– Irritability and very little urine in diapers
– Deep, rapid breathing
Severe Dehydration — Go to Hospital Immediately:
– Confusion, irritability, delirium
– Rapid heartbeat, rapid breathing
– Fever and chills
– No urine at all
– Fainting or inability to stay awake
Risks: Who is Most at Risk in Ghana’s Heat?
Anyone can get dehydrated, but these groups are most vulnerable:
1. Outdoor Workers and Okada Riders: Construction workers, farmers, hawkers, traffic police, and commercial drivers sweat for hours. You can lose over 1 liter of water per hour in direct sun.
2. Older Adults: As we age, our sense of thirst reduces and the body stores less water. Many also take diuretics (water pills) for hypertension.
3. Children: Children have higher water needs per kilogram and often forget to drink while playing.
4. People with Diarrhoea, Vomiting, or Fever: You lose both water and electrolytes very quickly. This is a major cause of dehydration deaths in Ghana.
5. People Exercising or Fasting: Prolonged exercise without electrolyte replacement and long fasting hours without water intake in the heat.
Risks if left untreated include heat cramps, heat exhaustion, heatstroke (a medical emergency), urinary tract infections, kidney stones, and dangerously low blood pressure.
Important: Drinking too much plain water in a very short time can also be dangerous. It can dilute sodium in the blood (hyponatremia) causing headache, confusion, and vomiting. This is rare but can affect athletes and outdoor workers who drink excessive water without replacing salts.
Prevention: How to Stay Hydrated in Ghana’s Heat
1. Don’t Wait to Be Thirsty — Drink Regularly
Adults should aim for 2.5 to 3 litres (8-12 cups) per day, more if you work outdoors or exercise. Keep a reusable water bottle with you.
2. Replace Electrolytes, Not Just Water
When you sweat heavily, you lose salt. For prolonged heat exposure:
– Use Oral Rehydration Solution (ORS) — available at all Citi Pharmacy branches. It is better than plain water for moderate dehydration.
– Drink coconut water — Ghana’s natural electrolyte drink, rich in potassium.
– Add a pinch of salt + orange or eat fruits with meals.
– Reserve sugary sports drinks for intense, prolonged activity; water is enough for most daily activities.
3. Eat Your Water
Ghanaian foods with high water content help:
Watermelon, cucumber, oranges, pineapple, tomatoes, lettuce, kontomire stew (light), and soups with more water. Hausa koko, palm nut soup base (without excess oil), and fruits are better than heavy, oily foods in the heat.
4. Smart Habits for the Heat
– Wear light, loose, breathable clothes (cotton) and a hat
– Schedule outdoor work/exercise for early morning (before 10am) or evening
– Set phone alarms for water breaks every 45-60 minutes if you work outside
– Check your urine: Pale straw or lemonade color = hydrated. Dark yellow = drink more.
– Avoid excess caffeine, energy drinks, and alcohol — they make you urinate more.
– Infuse water with lemon, lime, or mint if plain water is boring.
What to Do If You Are Already Dehydrated?
Mild: Sip ORS slowly, move to a cool shaded place, rest. Avoid sachet drinks with high sugar.
Severe: If you have confusion, fainting, rapid heart rate, or cannot keep fluids down, seek urgent medical care. IV fluids may be needed.
FAQs
1. How much water should I really drink in Ghana’s heat?
There is no single number. The CDC and dietitians recommend 2-3 litres daily for most adults, plus extra for sweat. In Ghana’s 32-38°C heat, outdoor workers may need 4-5 litres spread throughout the day. The best guide is your urine color and thirst — drink enough to keep urine pale yellow.
2. Is coconut water better than plain water for dehydration?
For mild dehydration from heat and sweating, coconut water is excellent because it contains natural electrolytes (potassium, sodium). For diarrhoea/vomiting, ORS is still the gold standard because its salt-sugar ratio is clinically tested to replace losses.
3. What are the first signs of dehydration I should not ignore?
Headache, fatigue, dark urine, dry mouth, and dizziness when standing up. Many people in Ghana mistake early dehydration for malaria or stress. If you have these symptoms plus less urination, increase fluids immediately.
4. Can drinking too much water be harmful?
Yes, but it’s uncommon. Drinking an excessive amount of plain water very quickly (e.g., >1 litre per hour for many hours) during prolonged exercise without food/salt can cause low blood sodium (hyponatremia). Symptoms are similar to dehydration: headache, nausea, confusion. Balance water with food and electrolytes, and don’t force beyond thirst unless you are sweating heavily.
Don’t let the heat knock you down. Stock up on ORS, electrolyte drinks, and reusable water bottles at any Citi Pharmacy branch in Ho or order online. Chat with our pharmacist now if you feel dehydrated.
