Proper Opening Angle
When opening a sun umbrella, try to open the canopy as wide as possible to form a large arc. This increases the shaded area and better blocks sunlight. For example, when resting outdoors, opening the umbrella to its maximum extent will allow you to be completely in the shade.
Adjusting the Direction to Face the Sun
When using it, adjust the direction of the sun umbrella according to the direction of the sun. The canopy should face the sun directly to maximize its sun-shading effect. For example, if the sun is in the east in the morning, open the umbrella facing east; if the sun is in the west in the afternoon, open the umbrella facing west.
Maintaining an Appropriate Distance from the Body
Do not hold the sun umbrella tightly against your body. Maintain a certain distance from your body, generally 30-50 cm is best. This allows for air circulation and a cooler feeling. For example, when walking, tilt the umbrella slightly outwards.
Avoiding Use in Strong Winds
Do not use a sun umbrella in strong winds. Strong winds can easily blow the umbrella inside out and may damage it. Now it's best to find a safe place to avoid the sun.
