5. Tearing and nasal stuffiness
Physical movements expand and narrow the sinus vessels. These can also cause allergies or rhinitis.
Remedy: Work out in an air-conditioned gym or if in the fresh air stay away from roads.
6. Muscle twitching
These spasms happen due to exhaustion and an imbalance of electrolytes.
Remedy: Drink water throughout workouts. Coldwater is helpful but a sports drink is better to have. Also, do some stretching after gym sessions.
