Summer sun in the mountains: planning the route and rest stops
A fresh start can make you forget about sunscreen, especially if the first stretch is through the woods. Further on, the route may open up, the altitude change, and stops become exposed. Prepare your protection by looking at the entire hike, not just the weather at the parking lot.

The program includes the outward journey, stop, and return
Check the forecast conditions and the UV index of the area, then identify the sections without shelter. The WHO reminds us that UV intensity increases with altitude: cooler air is not a measure of protection. If the route includes residual snow, also consider the presence of reflective surfaces.
Wear clothing that allows you to cover exposed areas and sunglasses with UV protection. A hat must be suitable for the activity and actually used during the walk.
The bottle in the backpack must be reachable
Apply the product before exposure and place it in an accessible compartment. If you have to empty the entire backpack to get it, you risk postponing the reapplication until the end of the route. Plan a safe stop suitable for the action.
For Biomed, the label indicates generous application and frequent reapplication, especially after bathing and towel drying. During trekking, also consider sweating, drying, and clothing changes: rolled-up sleeves can expose areas that were covered at the beginning.
The panoramic break is still part of the exposure
Arriving at the destination does not automatically end the need for protection. Lunch on an open meadow or a long stop on a terrace can add time outdoors. Seek shelter and keep necessary items accessible.
If the tour gets longer or you cannot manage the routine, review the program. Do not use SPF to calculate a guaranteed number of hours: the route must also be chosen based on your protection possibilities and the personal advice you have received.
Frequently asked questions
If it is cold at altitude, can I avoid sunscreen?
Temperature does not measure UV; consider altitude, conditions, and UV index.
Do I need to think about protection even during the stop?
Yes: time outdoors continues while you rest or eat lunch in an exposed area.
