Long days, warm nights, vacations, parties—summer is full of good times, but not always good sleep. If you’re waking up groggy, tossing and turning, or crashing in the middle of the afternoon, you’re not alone.
Here’s why summer messes with your sleep—and what you can do about it.
1. Late Sunsets Throw Off Your Clock
Your body’s internal clock—aka your circadian rhythm—relies on light and darkness. Longer daylight hours can delay melatonin production, making it harder to feel sleepy at your usual time.
Fix it:
- Dim the lights 1–2 hours before bed.
- Try blackout curtains to block evening light.
- Limit screen time in the evening.
2. Heat Disrupts Deep Sleep
Your body needs to cool down slightly to fall into deep, restorative sleep. But a hot bedroom—or a heatwave—can make that nearly impossible.
Fix it:
- Set the thermostat to 65–68°F if possible.
- Use breathable cotton sheets and a fan.
- Take a cool shower before bed to lower body temperature.
3. Summer Habits Break Routines
Vacations, late dinners, and irregular bedtimes are fun—but they can mess with sleep consistency, especially for kids.
Fix it:
- Stick to a regular sleep-wake time when possible.
- Limit heavy meals and alcohol before bed.
- Wind down with a consistent pre-bed ritual.
Bottom Line
You don’t have to sacrifice sleep for summer fun. With a few tweaks to your habits and sleep environment, you can rest easier—and enjoy brighter days with more energy.
