• Essential items to have in your backpack when going trekking: fully charged phone, multi-tool knife, lighter, flashlight, personal first-aid kit, snack food, water, rain jacket, insect repellent, whistle.
• When going downhill, tightly fasten your shoelaces around your ankles to reduce pressure on the front of your feet.
• If you have weak knees, consider bringing knee braces to provide support when going up and down slopes.
• For ascending slopes, shorten your trekking poles, and for descending slopes, lengthen them. Using two trekking poles is more effective than using just one.
• Stay hydrated, taking small sips of water at regular intervals.
• If you have low physical stamina, take regular breaks. The frequency and duration of breaks depend on the terrain and your health. For example, when trekking uphill, take a 1-minute break every 5 minutes of climbing.
• Never separate from the group or engage in individual activities without informing others in the group or the guide.
• If you realize that you are lost, cannot communicate via phone, and are unsure of the correct direction, stop and wait for someone to come find you. Periodically signal for help, for example by making a smoky fire and blowing a whistle.
• If you're trekking in hot and humid weather, you might encounter leeches in the jungle. To prevent them from latching onto your skin, wear long pants and tuck them into your socks. Use a gaiter to secure the pants around your ankles. Additionally, use an insect repellent spray, like DEET, on your shoes, socks, and up to your knees. It's recommended to pour the DEET into a spray bottle for convenience and reapply it after crossing streams.

These tips are valuable for a safe and enjoyable trekking experience, especially when venturing into challenging terrain and environments.
