How to reduce the effects of dry weather
Dry weather causes burning eyes and dry skin. It also favors allergic attacks and the worsening of respiratory diseases — without rain, pollutants and other allergens remain suspended in the air for longer.
To minimize these problems, the main advice is to keep your body hydrated. In addition to drinking water, experts suggest drinking coconut water and isotonic drinks to replace mineral salts.
To relieve irritation in the airways, the recommendation is to use saline solution for nasal washing and inhalation.
These precautions must be reinforced when there are children or elderly people at home. The caliber of children’s airways is smaller and their immune system is not yet fully developed, while people over 60 years of age have reduced immunity and greater difficulty in recognizing dehydration.
The skin also deserves attention. The ideal is to avoid baths with very hot water and apply moisturizer daily.
Keeping environments well ventilated, spreading wet towels and bowls of water around the house are other actions that contribute to increasing comfort.
