Beat the Heat: What You Need to Know About Hydration This Summer
May 20, 2026
Summer in South Carolina doesn’t ease in — it arrives. With temperatures and humidity already climbing, staying properly hydrated isn’t just good advice; it can be a matter of safety. Here’s what to know about heat exhaustion, dehydration, and why electrolytes matter as much as water.
Recognizing Heat Exhaustion
Common symptoms include heavy sweating, weakness or fatigue, dizziness, headache, nausea, muscle cramps, rapid heartbeat, cool and clammy skin, and fainting. If symptoms progress to confusion, loss of consciousness, dry skin without sweating, or a body temperature above 104 degrees, that’s heat stroke — a medical emergency requiring immediate attention.
Why Hydration Matters
Even mild dehydration affects energy, concentration, endurance, and mood. Signs include dry mouth, dark yellow urine, fatigue, headaches, dizziness, and muscle cramps. Pale yellow urine generally means you’re well hydrated.
General daily guidelines: women need about 91 ounces; men about 125 ounces. A simple rule many people use is to drink roughly half their body weight in ounces daily — so a 160-pound person would aim for around 80 ounces. Those who exercise, work outdoors, or live in hot climates need significantly more.
The Role of Electrolytes
Electrolytes — sodium, potassium, magnesium, calcium, and chloride — regulate muscle contractions, nerve signaling, fluid balance, heart rhythm, and blood pressure. Sweat depletes both water and electrolytes, especially sodium. Drinking only plain water after heavy sweating can dilute electrolyte levels further, worsening fatigue, cramps, and headaches.
Good sources include electrolyte drinks, coconut water, bananas, oranges, dairy, salted foods, leafy greens, and nuts.
Hydration During Activity and Heat
Sip consistently throughout the day rather than drinking large amounts at once. Start hydrating before activity begins, include electrolytes during prolonged sweating, and continue replacing fluids gradually afterward.
Simple DIY Electrolyte Drink
- 16 to 24 oz water
- 1/4 tsp sea salt or Himalayan salt
- Juice of 1/2 lemon or lime
- 1 tsp honey or maple syrup (optional)
- Pinch of cream of tartar for extra potassium (optional)
Coconut water naturally contains potassium and some electrolytes, though it’s lower in sodium — adding salt helps balance it.
If you have kidney disease, high blood pressure, or take medications affecting sodium or potassium levels, consult a healthcare professional before using concentrated electrolyte drinks regularly.
