From heat-related illnesses to recreation-related injuries, EDs see a noticeable surge during warmer months.

Why Summer Is So Busy for Emergency Departments

Longer days and warmer temperatures encourage more time outdoors. That increase in activity, paired with heat and travel, creates the perfect storm for injuries and health emergencies. Children are out of school and participating in camps and sports. Families are traveling, hiking, swimming, and biking. All of this increases exposure to risks that are less common during colder months.


Common Reasons for Summer ED Visits

Here are the most frequent conditions that bring people to the ED during summer:

1. Heat-Related Illnesses

High temperatures and humidity can quickly overwhelm the body’s ability to cool itself.

  • Heat exhaustion symptoms include dizziness, nausea, heavy sweating, and weakness
  • Heat stroke is more serious and can involve confusion, loss of consciousness, or a body temperature above 103°F

When to go to the ED: 
If someone shows signs of heat stroke, stops sweating, becomes confused, or loses consciousness, seek emergency care immediately.


2. Dehydration

Spending time outdoors, especially during physical activity, increases fluid loss.

  • Symptoms include dry mouth, fatigue, dizziness, and decreased urination
  • Children and older adults are particularly at risk

When to go to the ED: 
If dehydration leads to fainting, confusion, or an inability to keep fluids down, it is time for emergency care.


3. Water-Related Injuries

Swimming pools, lakes, and boating activities can lead to accidents.

  • Near-drowning incidents
  • Diving injuries
  • Cuts or head trauma

When to go to the ED: 
Seek immediate care for breathing difficulties, head or neck injuries, or if someone was submerged and is not acting normally afterward.


4. Sports and Recreational Injuries

Summer sports and activities increase the chance of injury.

  • Sprains, fractures, and dislocations
  • Head injuries from biking, skating, or contact sports

When to go to the ED: 
Go to the ED for suspected fractures, severe pain, inability to move a limb, or any head injury involving loss of consciousness or confusion.


5. Burns and Firework Injuries

Grilling, campfires, and fireworks are common summer activities with real risk.

  • Thermal burns from grills or fire pits
  • Firework-related injuries to the hands, eyes, or face

When to go to the ED: 
Seek emergency care for burns that are large, deep, blistering, or located on the face or joints, as well as any firework-related injury.


6. Insect Stings and Allergic Reactions

More time outdoors means more exposure to insects like bees, wasps, and mosquitoes.

  • Mild reactions include redness and swelling
  • Severe allergic reactions can include difficulty breathing, swelling of the face or throat, and hives

When to go to the ED: 
Call 911 or go to the ED immediately if there are signs of an allergic reaction or anaphylaxis.


7. Travel-Related Illness and Accidents

Summer travel can bring unfamiliar environments and an increased risk of accidents.

  • Car accidents
  • Foodborne illness
  • Cuts, falls, or injuries in new surroundings

When to go to the ED: 
Serious injuries, persistent vomiting, or severe abdominal pain should be evaluated right away.


Activities That Require Extra Caution

To reduce your risk of an emergency visit, take extra precautions during these common summer activities:

  • Outdoor exercise: Stay hydrated, avoid peak heat hours, and take breaks
  • Swimming and water sports: Never swim alone and supervise children closely
  • Biking and skating: Always wear helmets and protective gear
  • Grilling and fire pits: Keep a safe distance and never leave fires unattended
  • Fireworks: Attend professional shows rather than using fireworks at home
  • Hiking and camping: Bring enough water, know your route, and watch for weather changes

Know Before You Go

Not every summer mishap requires an ED visit. Urgent care can handle many minor issues, such as mild sprains, small cuts, or minor burns. But if symptoms are severe, worsening, or life-threatening, the ED is the right place.


Stay Safe and Enjoy the Season

Summer should be a time for making memories, not medical emergencies. By understanding the risks and knowing when to seek care, you can better protect yourself and your loved ones. A little preparation and awareness can go a long way in keeping your summer fun and safe. Know where to go in case of an emergency.
