Healthy Summer Travel: Your Complete Guide to Worry-Free Adventures in 2025

I want to take you back to that summer morning when I woke up with skin as red as a lobster. Not exactly the vacation moment I had in mind. I had enjoyed a lovely bike ride along the coast in The Gambia, but lying there I realized that healthy summer travel is more than just throwing a bottle of sunscreen in your suitcase.

That night taught me the hard way. Nothing ruins a dream vacation as effectively as lying awake groaning in the night because you underestimated the power of the sun. Since then, I’ve become a real advocate for smart travel: Adventurous but with common sense.

Sun Protection: Your First Line of Defense

The summer sun is more intense than you think, especially in vacation destinations where UV radiation is often higher than at home. Good sun protection goes beyond just applying sunscreen.

Choose the Right Sunscreen

• SPF 50 is your minimum for southern destinations
• Use broad spectrum protection (UVA and UVB)
• Choose waterproof formulas for swimming and sports
• Don’t forget: even on cloudy days, 80% of UV radiation gets through

Timing and Shade

Avoid the sun between 11:00 AM and 3:00 PM. In some countries, the sun is at its strongest later in the afternoon. Plan your beach visits early morning or later in the afternoon. Your skin will thank you, and the temperatures are much more comfortable then.

Clothing as Protection

Light pants and a shirt protect better than any sunscreen. Choose light colors that reflect heat and natural fabrics like cotton or linen. I wear yoga leggings a lot. These are also perfect for protecting me from the harsh sun.

Recognizing and Preventing Heat Exhaustion

Heat exhaustion develops gradually with symptoms like headaches, dizziness, nausea, and fatigue. In severe cases, this can lead to heat stroke.

Prevention:

• Drink regularly, even without thirst
• Seek shade regularly
• Wear a hat and sunglasses
• Adapt activities to the climate

I actually always carry a large water bottle with me.

Water Safety: Enjoying Without Risks

Are you already lying comfortably sunbathing on the beach and want to cool off in the clear blue seawater?

Swimming Safely

• Swim only at lifeguarded beaches
• Always respect warning flags
• Watch for undertows and surf
• Never swim alone

Pools and Hotels

These tips seem obvious, but I’ll mention them anyway:

• Check the depth before jumping
• Watch for slippery tiles around pools
• Keep children constantly supervised

Water Sports

• Always wear a properly fitting life jacket
• Check equipment beforehand
• Ask about local conditions
• Don’t go on the water in bad weather

Building Your Summer Travel Medicine Kit

A well-assembled travel medicine kit can make the difference between a minor setback and a major disaster.

Sun Protection and Skincare

• Sunscreen SPF 50+ (bring extra)
• After-sun lotion or aloe vera gel
• Lip balm with UV protection
• Cooling gel for insect bites

Medications and First Aid

• Pain relievers (acetaminophen and ibuprofen)
• Anti-diarrheal medication
• Electrolyte sachets for rehydration
• Disinfecting wound spray
• Bandages in various sizes
• Thermometer

Insect Protection

• DEET-containing spray (minimum 20% DEET)
• Mosquito net for tropical destinations
• Antihistamine cream for bites

Tropical Destinations

For travel to tropical areas, consult a travel doctor in time for advice on vaccinations and whether malaria prevention is recommended.

Smart Hydration in Warm Climates

In warm climates, you lose more fluids than you realize. The general rule of 8 glasses of water per day is absolutely insufficient in summer.

Practical Hydration Tips

• Drink at least 2-3 liters per day in hot weather
• Start the day with a large glass of water
• Drink every hour, even without thirst
• Choose water with electrolytes for intensive activities

What to Avoid

• Alcohol dehydrates and increases risk of heat exhaustion
• Ice-cold drinks can cause stomach problems
• Too many sugary drinks actually make you thirstier

Recognize dehydration: dark urine, headache, dizziness, dry mouth, and fatigue.

Safe Eating in Warm Countries

Food poisoning can ruin your vacation within a day. With some basic rules, you can prevent most problems.

Golden Rules

• Eat meat? Only eat well-cooked meat and fish
• Avoid raw vegetables and unpeeled fruit
• Choose busy restaurants with local guests
• Drink only bottled or boiled water
• Be careful with ice cubes

When to See a Doctor

Seek medical help for fever above 100.4°F (38°C), blood in stool, severe abdominal pain, signs of dehydration, or complaints lasting longer than 3 days.

Special Attention for Children

I’ll touch on this briefly, though I have no experience with children while traveling. Children are extra vulnerable to heat and sun. Their skin is more sensitive and they overheat more quickly. Make sure they also travel healthy this summer.

Tips for Children

• Use mineral sunscreen (zinc oxide or titanium dioxide)
• Provide plenty of shade during play
• Dress them in light, covered clothing
• Ensure extra hydration
• Plan activities early or in the evening

Mineral sunscreen is also better suited for people with sensitive skin.

Insurance and Preparation

Check Your Coverage

• Medical costs abroad
• Repatriation for serious illness
• Coverage for sports activities and water sports
• Cancellation for medical emergencies

Practical Preparation

• Register your trip with the Ministry of Foreign Affairs
• Take contact details of your embassy
• Make copies of important documents
• Learn about local emergency procedures
