It is not recommended to wear contact lenses while freediving. The pressure changes that occur when diving deep underwater can cause discomfort and potential damage to the eyes if wearing contact lenses. Additionally, there is a risk of losing the lenses in the water, which can be dangerous for both the wearer and the marine environment. It is best to consult with an eye care professional for advice on the safest options for vision correction while freediving. **

Packing air while freediving can be both dangerous and beneficial, depending on how it is done. When done incorrectly or excessively, packing air can lead to overexpansion of the lungs, which can cause lung barotrauma or arterial gas embolism, both of which are serious and potentially life-threatening conditions. However, when done properly and in moderation, packing air can increase lung volume and improve breath-holding capacity, allowing freedivers to stay underwater for longer periods of time. It is important for freedivers to receive proper training and guidance on how to safely and effectively pack air to minimize the risks associated with this technique. **

Sustainability is very important to me when shopping. I prioritize purchasing products that are environmentally friendly, ethically sourced, and have minimal impact on the planet. I believe in supporting companies that are committed to sustainable practices and reducing their carbon footprint. I also try to minimize waste by choosing products with minimal packaging and opting for reusable or biodegradable options whenever possible. Overall, sustainability is a key factor in my purchasing decisions and I strive to make choices that align with my values. **

Online shopping offers convenience and the ability to compare prices and products from the comfort of your own home. However, traditional shopping allows for a more tactile and sensory experience, as well as the immediate gratification of taking home your purchases. Both have their advantages, and the choice ultimately depends on personal preferences and the specific needs of the shopper. **

A neck weight in freediving or apnea diving typically weighs between 1-3 kilograms (2.2-6.6 pounds). The purpose of the neck weight is to help the diver achieve neutral buoyancy in the water, allowing them to descend and ascend more easily without expending excess energy. The weight is positioned around the neck to help the diver maintain a streamlined body position and reduce the effort required to equalize the ears. The specific weight used can vary depending on the individual diver's body composition and diving conditions. **

Online shopping offers convenience and the ability to compare prices and products from the comfort of your own home. It also allows for easy access to customer reviews and a wider selection of items. On the other hand, in-store shopping provides the opportunity to physically see and touch the products before making a purchase, as well as the immediate gratification of taking the item home with you. Ultimately, the choice between online and in-store shopping depends on personal preferences and the specific needs of the shopper. **
