Cotton is natural, breathable, absorbent, and sustainable. Polyester, on the other hand, is a synthetic fiber that doesn't breathe well, repels water, and isn't sustainable.
100% COTTON BENEFITS:
All Cotton is hypoallergenic, ideal for sensitive skin, and raises your natural vibrational frequency for optimal health. Organic cotton resonates at 100-110 Mhz (non organic cotton from 70-100 Mhz). Linen and pure wool both resonate at a tremendous 5000 hz - that's 50 times the natural frequency of the human body, raising vibrational frequency naturally. The human body resonates between 62 Mhz and 70 Mhz while healthy. Dipping below into the 50's indicates sickness or inbalance which is unhealthy revealing underlying health issues. Wearing garments that naturally boost your vibrational frequency is ideal for optimal health.
Cotton lets the skin breathe and reduces the risk of skin rashes while also repelling dust mites, pollen, and other common allergens. Cotton fabric absorbs sweat and helps the body cool down. Cotton promotes better air circulation, which aids in the absorption and removal of body moisture caused by sweat via evaporation.
Environmentalists appreciate cotton due to its biodegradable and durablility, even when abused by dirt, repeated washes, and the climate.
