Your Colorado survival guide: Altitude, sun, heat and hydration
Starting a new semester can be an adjustment. And if you're new to Colorado, your body may need a little time to adjust, too.Ìý
Between the higher elevation, dry air and stronger sunshine, it's common to feel a little different during your first few days in Boulder. You might get tired more easily, notice a headache or wonder why you're out of breath after walking across campus.Ìý
Already been here a year or two? Consider this your annual reminder. Even returning Buffs can feel the effects of altitude, dehydration or sun exposure after spending time away from Colorado.Ìý
The good news: most students adjust within a few days. A few simple habits can help you feel your best, whether you're heading to class, cheering at Folsom Field or planning your first hike.
ÌýÌýFeeling tired, out of breath or getting headaches? It could be the altitudeÌý
Â鶹Ãâ·Ñ°æÏÂÔØBoulder sits at about 5,300 feet above sea level, and nearby trails like the Flatirons climb above 7,000 feet. If you're coming from a lower elevation, your body needs time to adjust to having less oxygen available.Ìý
During your first few days, it's normal to feel more tired than usual, get winded more easily or develop a mild headache. But it's also important to recognize the signs of altitude sickness.Ìý
ÌýÌýWatch for these symptomsÌý
- HeadacheÌý
- Nausea or upset stomachÌý
- Dizziness or lightheadednessÌý
- Fatigue or low energyÌý
- Loss of appetiteÌý

ÌýÌýGive your body time to adjustÌý
If you're experiencing mild symptoms:Ìý
- Slow down and take it easy for a day or two.Ìý
- Drink more water than you normally would.Ìý
- Skip alcohol, vaping and intense workouts until you're feeling better.Ìý
- If possible, head to a lower elevation if symptoms get worse.Ìý
- Ibuprofen or acetaminophen can help relieve headaches.Ìý
Most mild altitude symptoms improve with rest and hydration.Ìý
ÌýÌýWhen to seek medical helpÌýÌý

ÌýÌýYes, you really can get sunburned walking to classÌý
Colorado's sunshine hits differently. At higher elevations, UV rays are stronger, which means you can burn faster—even when it's cool or cloudy outside.Ìý
Whether you're studying on Norlin Quad, heading to class or spending the weekend in the mountains, sun protection should be part of your routine.Ìý
ÌýÌýYour Colorado sun checklistÌý

ÌýÌýYour water bottle is about to become your best friendÌý
Colorado's dry climate and higher elevation can leave you dehydrated faster than you might expect, even if you don't feel sweaty.Ìý
Whether you're walking across campus, spending the afternoon at a club event or hiking with friends, drink water throughout the day instead of waiting until you're thirsty.Ìý
If you're active outdoors, aim for about 32 ounces (one liter) of water every two hours. If you're heading into the mountains, bring extra water so you're prepared.Ìý
ÌýÌýColorado heat can sneak up on youÌý
Even though Colorado is known for its mild climate, summer and even fall afternoons can get hot quickly. If you're walking across campus, attending an outdoor event or exploring Boulder, pay attention to the heat index, which reflects how hot it actually feels.Ìý
When the heat index reaches 90°F or higher:Ìý
- Take breaks in the shade or air conditioning.Ìý
- Drink water regularly. Sports drinks can also help replace electrolytes after heavy sweating.Ìý
- Limit alcohol and caffeine if you're feeling dehydrated.Ìý
- Cool down with a cold shower, wet towel or ice pack.Ìý
- Wear lightweight, loose-fitting clothing.Ìý
