HOUSTON \u2013 The summer heat isn\u2019t just uncomfortable. It can become dangerous fast.<\/p>\n
Whether you\u2019re planning a Fourth of July barbecue, taking the kids to the splash pad or training for a marathon, timing can make a huge difference during a Houston summer.<\/p>\n
With temperatures regularly climbing into the mid-to-upper 90s and heat index values soaring above 105 degrees, doctors and meteorologists recommend scheduling outdoor activities during cooler parts of the day whenever possible.<\/p>\n
Here\u2019s when experts say it\u2019s safest, and riskiest, to be outside.<\/p>\n
Running or jogging<\/p>\n
\u2705 Best times<\/p>\n
5:30 a.m. to 8 a.m.<\/p>\n
After 8 p.m. (if routes are well-lit)<\/p>\n
Morning temperatures are usually 10 to 20 degrees cooler than the afternoon, and the sun is less intense.<\/p>\n
\u274c Avoid<\/p>\n
This is when pavement temperatures can exceed 140 degrees, increasing both heat stress and burn risk.<\/p>\n
Tips<\/p>\n
Slow your pace.<\/p>\n
Carry water.<\/p>\n
Wear light-colored, moisture-wicking clothing.<\/p>\n
Stop immediately if you become dizzy or nauseated.<\/p>\n
Walking the dog<\/p>\n
\u2705 Best<\/p>\n
Before 8 a.m.<\/p>\n
After sunset<\/p>\n
\u274c Avoid<\/p>\n
Late morning through early evening<\/p>\n
Sidewalks and asphalt become hot enough to burn paws within seconds.<\/p>\n
Bike rides<\/p>\n
\u2705 Best<\/p>\n
Sunrise to 9 a.m.<\/p>\n
Evening after 7:30 p.m.<\/p>\n
Cycling creates airflow, but riders still lose large amounts of sweat without realizing it.<\/p>\n
\u274c Avoid<\/p>\n
Heat radiating from roads can make conditions significantly hotter than the air temperature.<\/p>\n
Kids at the playground<\/p>\n
\u2705 Best<\/p>\n
Before 10 a.m.<\/p>\n
After 6:30 p.m.<\/p>\n
\u274c Avoid<\/p>\n
Playground slides, swings and metal equipment can become dangerously hot.<\/p>\n
Children also overheat faster because their bodies don\u2019t regulate temperature as efficiently as adults.<\/p>\n
Water parks and splash pads<\/p>\n
\u2705 Best<\/p>\n
Opening until about 11 a.m.<\/p>\n
After 4 or 5 p.m.<\/p>\n
Many people assume they\u2019re safe because they\u2019re in the water.<\/p>\n
But water parks can actually increase dehydration because visitors often don\u2019t realize how much they\u2019re sweating.<\/p>\n
\u274c Highest risk<\/p>\n
Swimming pools<\/p>\n
\u2705 Best<\/p>\n
Morning<\/p>\n
Late afternoon<\/p>\n
Evening<\/p>\n
Pools help cool you down, but swimmers can still become dehydrated and sunburned.<\/p>\n
Don\u2019t skip drinking water just because you\u2019re in the pool.<\/p>\n
Barbecues and backyard parties<\/p>\n
\u2705 Best<\/p>\n
If hosting an afternoon gathering:<\/p>\n
Provide shaded seating.<\/p>\n
Keep coolers stocked with water.<\/p>\n
Take breaks indoors.<\/p>\n
Limit alcohol in extreme heat.<\/p>\n
\u274c Toughest hours<\/p>\n
Standing over a grill can increase your body\u2019s heat load even more.<\/p>\n
Yard work<\/p>\n
\u2705 Best<\/p>\n
\u274c Avoid<\/p>\n
Lawn mowing is one of the leading summertime activities associated with heat illness because it combines heavy exertion with direct sunlight.<\/p>\n
Outdoor sports<\/p>\n
\u2705 Best<\/p>\n
Before 9 a.m.<\/p>\n
After sunset<\/p>\n
Teams should schedule frequent water breaks and allow athletes to acclimate gradually to the heat.<\/p>\n
General outdoor festivals or events<\/p>\n
If you\u2019re attending festivals, farmers markets or community events:<\/p>\n
Go early if possible.<\/p>\n
If you\u2019re outside during the afternoon:<\/p>\n
Find shade every 20-30 minutes.<\/p>\n
Drink water before you\u2019re thirsty.<\/p>\n
Wear a wide-brim hat.<\/p>\n
Apply sunscreen every two hours.<\/p>\n
The hours everyone should pay attention to time heat risk:<\/p>\n
5:30-9 a.m. – Best time for nearly every outdoor activity<\/p>\n
9-11 a.m. – Generally safe but warming quickly<\/p>\n
11 a.m. – 4 p.m. Highest heat risk, avoid strenuous activity<\/p>\n
4-6 p.m. – Still very hot despite lowering sun angle<\/p>\n
After 7 p.m. – Better, though humidity remains high<\/p>\n
Know the warning signs<\/p>\n
Heat exhaustion symptoms include:<\/p>\n
Heavy sweating<\/p>\n
Weakness<\/p>\n
Dizziness<\/p>\n
Headache<\/p>\n
Muscle cramps<\/p>\n
Nausea<\/p>\n
