Dog Days 2025: This is how you can avoid illnesses in high temperatures.

The dog days are the summer season when the heat intensifies significantly—usually in July and August. It increases the risk of heat stroke, dehydration, and other heat-related problems, especially for vulnerable individuals such as children, the elderly, chronically ill, and pets. To prevent these ailments—including the worst of all: death—these are some recommendations from UNAM specialists.

Six recommendations to prevent the 2025 heat wave

1. Hydrate constantly and replenish electrolytes

Drink plain water constantly, even if you don't feel thirsty. Also incorporate electrolyte solutions in case of heavy sweating or outdoor work; eat fruits and vegetables with high water content.

2. Dress appropriately

Wear lightweight clothing made of natural fabrics like cotton or linen and light colors to facilitate heat dissipation. Accessorize with a hat, UV-filtering sunglasses, and sunscreen (minimum SPF 30, ideally 50+).

3. Adjust your outdoor schedules and habits

Avoid sun exposure between 11:00 a.m. and 3:00 p.m., when the radiation is strongest. Also, exercise during the early hours or late afternoon, or in shady areas with adequate shade.

4. Refresh your spaces and beyond

At home or in the office, install thermal curtains, blinds, or blackout shades , take advantage of cross ventilation, and place ice in front of the fan. Externally, use cold towels or apply ice cubes to your wrists, neck, or temples to quickly lower your body temperature.

5. Prepare a first-aid kit

It includes bottled water, oral saline, a thermometer, burn gels, and wet wipes. It also provides basic first aid supplies: gauze, bandages, disinfectants, and a flashlight, for immediate treatment in case of heat exhaustion or burns.

6. Protect the most vulnerable (children, seniors, pets)

Don't leave anyone in the car, even for "a few minutes," as the internal heat can be deadly. If you have pets: avoid hot pavement, take them for walks before 11 a.m. or after 5 p.m., and leave fresh water available. On the other hand, if you care for someone with chronic illnesses or on medication, consult a doctor, as certain medications cause sun sensitization.
