During periods of extreme heat, your body loses more water through sweating as it tries to stay cool. If this lost fluid is not replaced, dehydration can occur. Dehydration can affect anyone, but young children, older adults, pregnant women, and people who work outdoors are at a higher risk.
Signs and symptoms of dehydration
Watch out for these common warning signs:
- Dry mouth and increased thirst
- Headache
- Dizziness or lightheadedness
- Dark yellow urine
- Urinating less often than usual
- Feeling weak, tired, or unusually fatigued
- Rapid heartbeat
- Sunken eyes, especially in young children
How to prevent dehydration during hot weather
Simple steps can help you stay hydrated and healthy:
- Drink water regularly throughout the day, even if you do not feel thirsty.
- Encourage children to drink water frequently.
- Continue breastfeeding infants, as breast milk helps keep babies hydrated.
- Use Oral Rehydration Solution (ORS) if there is diarrhea or vomiting.
- Take breaks and rest in cool or shaded areas whenever possible.
- Limit alcohol, energy drinks, and sugary beverages, as they may contribute to fluid loss.
When to speak with a doctor
Seek medical advice if:
- Weakness or tiredness continues despite drinking fluids.
- Vomiting or diarrhea does not improve.
- A child is passing very little urine.
- An older adult becomes confused, unusually weak, or less responsive.
When to go to the hospital immediately
Emergency medical care may be needed if:
- The person faints or loses consciousness.
- The person becomes confused or disoriented.
- A child is unable to drink fluids.
- There has been no urine output for several hours.
Stay safe in hot weather
Hot weather can quickly lead to dehydration if you do not replace lost fluids. Make it a habit to drink enough water, protect yourself from excessive heat, and pay attention to early warning signs. Taking action early can help prevent serious health complications.
