Milind Soman, the 60-year-old Indian actor and fitness icon, recently completed an impressive 15 km swim across the Strait of Gibraltar, marking a unique challenge from Europe to Africa. He began his swim on May 1, starting from Tarifa, Spain, and reaching the coast of Morocco. Soman shared his experience on Instagram, describing the swim as 'beautiful' and receiving accolades from fans and fellow celebrities. Fitness expert Garima Goyal explained that such extreme physical challenges can push the body's immunity and resilience to their limits. While moderate exercise supports immune health, intense endurance activities like long-distance swimming can lead to a temporary dip in immunity, known as the 'open window' phase. Recovery and nutrition play critical roles in maintaining health during such challenges, with adequate protein, carbohydrates, and micronutrients necessary for muscle repair and immune function. Controlled breathing during swimming can also improve lung capacity, enhancing overall performance and resilience.
