A tennis ball is an essential travel companion for anyone who gets stiff on long flights.

Winter’s chilly weather can make muscles feel tight and less flexible. Cold temperatures restrict blood flow, reducing oxygen delivery to muscles. This causes them to contract and become more prone to stiffness. Additionally, people tend to move less in winter, which can further contribute to muscle tension and discomfort. Stretching is a simple yet effective way to combat stiffness and improve overall flexibility.
