How to Prepare Kids for Outdoor Activity Season

With spring on the doorstep, the days are stretching longer, the sun is warming up again and the urge to get outside is rising — for children and parents alike. After months of indoor activities and grey afternoons, the outdoor season arrives like a breath of fresh air. Quite literally.

But the transition from winter to spring and summer should not happen overnight. Children who have spent the colder months mostly indoors need time to readjust to the sun, the heat and physical exertion outside. Proper preparation prevents sunburn, dehydration, excessive fatigue and other setbacks that can turn a fun afternoon into an ordeal.

This guide will help you get your children ready to enjoy the outdoor activity season safely and to the fullest.

Physical Preparation: Getting Back to Movement

After months with less outdoor activity, children's bodies need a gradual readjustment. Do not expect them to run marathons on the first sunny weekend.

How to make the transition:

• Start with short sessions: For the first few days, 30 to 45 minutes of outdoor activity is plenty. Increase gradually over two to three weeks.
• Alternate intense activity with rest: Running around the park is great, but intersperse it with breaks for water and catching breath.
• Vary the types of exercise: Walking, running, jumping, climbing, cycling. Each activity works different muscle groups and reduces the risk of repetitive strain.
• Respect the body's signals: If your child is flushed, panting heavily or complaining of pain, it is time to stop. Stamina builds over time, not by force.

For less active children: If your child spent the winter between the sofa and the screen, start even more gently. Twenty-minute walks, games in the garden, playing at the local playground. The goal is to build the habit before increasing the intensity.

Sun Safety: The Most Important Rule

The Lisbon sun is generous — and deceptive. Even in March and April, UV radiation can be strong enough to cause burns, particularly on fair and young skin.

Sun protection rules for children:

• SPF 50+ sunscreen: Apply 20 minutes before going outside. Reapply every two hours and always after swimming or sweating.
• Avoid peak hours: Between midday and 4pm, the sun is at its strongest. Where possible, plan outdoor activities for the morning or late afternoon.
• Wide-brimmed hat: Protects the face, ears and neck — the most vulnerable areas.
• Sunglasses with UV protection: Children's eyes are particularly sensitive. Invest in quality sunglasses with UV400 protection.
• UV-protective clothing: T-shirts and swimwear with UPF protection are an excellent choice for beach or pool days.

Tip: Make applying sunscreen a daily routine, like brushing teeth. If it becomes part of the habit, your child will never leave the house unprotected.

Hydration: More Water Than You Think

Children dehydrate faster than adults. A child's body has a higher proportion of water and sweats less efficiently, which makes hydration particularly important during outdoor activities.

Hydration guide:

• Before activity: Your child should drink water in the 30 minutes before starting.
• During activity: Offer water every 20 minutes, even if the child does not say they are thirsty. Thirst is already an early sign of dehydration.
• After activity: Continue offering water for at least an hour after exercise.

Recommended daily intake:

• Children aged 2 to 5: 1 to 1.3 litres per day
• Children aged 6 to 9: 1.3 to 1.5 litres per day
• Children aged 10 to 12: 1.5 to 2 litres per day

On hot days or during intense activity, these amounts should increase by 30 to 50 per cent.

What to avoid: Sugary juices and fizzy drinks do not replace water. If your child finds plain water boring, try adding slices of lemon, orange or a sprig of mint.

Clothing and Gear: What They Actually Need

Dressing children properly for outdoor activities is simpler than it seems. The golden rule: comfort before style.

Outdoor season essentials:

• Closed, comfortable trainers: With grippy soles and already broken in. New shoes can mean blisters.
• Layered clothing: Spring mornings can be cool while afternoons turn warm. Dressing in layers allows adjustment throughout the day.
• Cotton socks: Prevent blisters and absorb sweat. Always pack a spare pair.
• Lightweight backpack: For the water bottle, snack, sunscreen and an extra layer of clothing.
• Cap or hat: Essential from March onwards.

What not to bring: Clothes you do not want to see dirty. Outdoor activities involve soil, grass, water and mud. Accept this and dress children in clothes that can be machine-washed without a second thought.

Bug Protection

With warm weather come mosquitoes, ticks and other insects that love fresh young skin. Protection matters, especially in green areas and near water.

Protective measures:

• Age-appropriate repellent: Check the label — not all repellents are safe for young children. Products containing DEET should be used sparingly on children and avoided on babies under two.
• Light-coloured, long-sleeved clothing: In areas with more insects (woodlands, near streams), opt for long sleeves in light colours.
• Avoid strongly scented products: Perfumes and fragrant creams attract insects.
• Check the body after activity: After walks through dense vegetation, inspect the skin for ticks, particularly behind the ears, on the back of the neck and in skin folds.
• First-aid kit: Always carry antihistamine cream for bites and tweezers for tick removal.

Building Outdoor Stamina Gradually

Adapting to the outdoors is a process, not an event. Do not try to make up for months of winter in a single week.

Suggested transition plan:

• Weeks 1-2: Short outings of 30 to 45 minutes in urban parks. Free play at the playground. Simple games like catching balls or riding a scooter.
• Weeks 3-4: Increase to 1 to 2 hours of activity. Introduce light hikes and more active games. First picnic of the season.
• Week 5 onwards: Longer, more intense activities — cycling, climbing, surfing, athletics. By now, children will be readapted to the effort and the heat.

This gradual progression reduces the risk of injuries, sunburn and extreme fatigue, and helps children associate the outdoors with positive experiences rather than discomfort.

Best First Outdoor Activities of the Season

To kick off the season on the right foot, choose activities that are fun, accessible and do not require peak fitness.

• Picnics in the park: Simple, free and social. Bring a ball, a frisbee and friends.
• Bike rides along the cycle path: Flat, safe and with ice cream at the end (guaranteed motivation).
• Treasure hunts in the garden or park: Create clues and hide prizes. Children run without realising they are exercising.
• Taster sports sessions: Many surf, tennis, horse riding and climbing schools offer free or discounted trial lessons at the start of the season.
• Visits to educational farms: Contact with animals, vegetable gardens and open space. Perfect for younger children.
