You can’t always control germs, stress or the weather, but you can control how well you sleep. And your immune system will thank you.
Pairing good sleep habits with preventive steps, like a flu shot, gives your body the best defense this season.
Why Sleep Matters for Your Health
Sleep isn’t just downtime. During deep and restorative sleep, your body produces infection-fighting cells and antibodies that help protect you from illness.
Missing even a few hours can weaken your immune defenses and make you more susceptible to colds, flu and other infections.
Getting enough sleep also helps your body respond better to vaccines. That means your flu shot, or any vaccine, is more effective when you’re well-rested.
How Much Sleep Do You Really Need?
Most adults need 7–9 hours of quality sleep per night. Teens and young adults require slightly more.
The key isn’t just quantity. It’s also about quality. Interrupted or restless sleep doesn’t give your immune system the boost it needs.
Habits That Help You Sleep and Stay Healthy
Simple adjustments can make a big difference:
- Keep a routine. Go to bed and wake up at the same time each day, even on weekends.
- Create a sleep-friendly environment. Cool, dark and quiet rooms improve sleep quality.
- Limit screens before bed. Blue light from phones and TVs can interfere with your body’s natural sleep cycle.
- Avoid late-night caffeine or alcohol. Both can disrupt restorative sleep.
- Pair sleep with preventive care. Stay up to date on vaccines, including your annual flu shot, to protect yourself and your loved ones.
Sleep and Immunity Go Hand in Hand
Good sleep doesn’t just help your body fight off infections. It also improves mood, focus and energy, giving you the tools to tackle daily challenges. Think of it as a natural boost for your body’s defense system.
And when you combine it with practical steps like a flu shot, you’re giving your immune system the best chance to keep you healthy this season.
