Summer is the peak tourist season, with hot and humid weather. Travelers should remember to bring some sugar and salt.
Travelers spend long hours outdoors, and their daily meals are not as timely and convenient as at home. The increased physical activity consumes many nutrients in the body. The stored sugar in the body cannot meet the needs of exercise, and timely supplementation of nutrients can help people recover from travel and exercise fatigue more quickly. Eating a little chocolate or a piece of candy before traveling or exercising can replenish the body's energy, increase muscle and liver glycogen reserves, and help replenish the energy consumed by the body. Chocolate is energy and nutrient-dense, small in size, and easy to carry, making it an ideal energy and nutritional supplement.
People tend to sweat while traveling. When the body sweats heavily, sweat takes away a lot of inorganic salts, such as sodium, potassium, and magnesium. Therefore, drinking some light salt water during the journey is very necessary. Light salt water, made by dissolving 1 gram of salt in 500 milliliters of water, can cool you down and quench your thirst without harming the stomach and intestines. It can also replenish the body's needed salt in a timely manner and prevent electrolyte imbalance. When drinking water during the journey, it's best to drink small amounts frequently. Even if you're thirsty, don't gulp it down at once. Each time, 100 to 150 milliliters is appropriate, with an interval of about an hour.
In summer, you sweat a lot. When your towel becomes sticky, you can scrub it with salt, then rinse it with clean water and let it dry. This will make the towel soft and clean as new. Additionally, after a day of sightseeing and returning to your accommodation, adding a small amount of salt to your warm bath water can be refreshing, and your skin will also become smooth and comfortable.
