Improve Your Sleep & Boost Your Immune System
To begin a new path towards healthier sleep and a healthier lifestyle, begin by assessing your own individual needs and habits. See how you respond to different amounts of sleep.
Pay careful attention to your mood, energy and health after a poor night's sleep versus a good one. Ask yourself, "How often do I get a good night's sleep?" Like a good diet and exercise, sleep is a critical component to overall health.
To pave the way for better sleep, follow these simple yet effective healthy sleep tips, including:
- Stick to a sleep schedule, even on weekends.
- Practice a relaxing bedtime ritual.
- Exercise daily.
- Evaluate your bedroom to ensure ideal temperature, sound and light.
- Sleep on a comfortable mattress and pillows.
- Beware of hidden sleep stealers, like alcohol and caffeine.
- Turn off electronics before bed.
Sleep is a vital indicator of overall health and well-being. We spend up to one-third of our lives asleep, and the overall state of our "sleep health" remains an essential question throughout our lifespan.
Most of us know that getting a good night’s sleep is important, but too few of us actually make those eight or so hours between the sheets a priority. For many of us with sleep debt, we’ve forgotten what “being really, truly rested” feels like.
To further complicate matters, stimulants like coffee and energy drinks, alarm clocks, and external lights—including those from electronic devices—interferes with our "circadian rhythm" or natural sleep/wake cycle.
Sleep needs vary across ages and are especially impacted by lifestyle and health. To determine how much sleep you need, it's important to assess not only where you fall on the "sleep needs spectrum," but also to examine what lifestyle factors are affecting the quality and quantity of your sleep such as work schedules and stress.
Sleep Helps Boost Immune System
When it comes to your health, sleep plays an important role. While more sleep won’t necessarily prevent you from getting sick, skimping on it could adversely affect your immune system, leaving you susceptible to a bad cold or case of the flu. To keep yourself sniffle-free this season, here’s what you need to know.
Sleep and Cytokines
Without sufficient sleep, your body makes fewer cytokines, a type of protein that targets infection and inflammation, effectively creating an immune response. Cytokines are both produced and released during sleep, causing a double whammy if you skimp on shut-eye. Chronic sleep loss even makes the flu vaccine less effective by reducing your body’s ability to respond.
Stock Up on Naps
To stay healthy, especially during the influenza season, get the recommended seven to eight hours of sleep a night. This will help keep your immune system in fighting shape, and also protect you from other health issues including heart disease, diabetes, and obesity.
If your sleep schedule is interrupted by a busy workweek or other factors, try to make up for the lost rest with naps. Taking two naps that are no longer than 30 minutes each —one in the morning and one in the afternoon—has been shown to help decrease stress and offset the negative effects that sleep deprivation has on the immune system. If you can’t swing a half-hour nap during the workday, try grabbing a 20-minute siesta on your lunch hour, and another right before dinner.
Other Healthy Tactics
Of course, there’s more to boost your immunity and guarding against illness than getting ample sleep. It’s also important to practice smart stay-healthy strategies such as washing your hands with soap regularly, avoiding close contact with people who are obviously under the weather, and talking with your doctor about getting an annual flu shot. And remember: Even if you do come down with a case of seasonal sniffles, you’ll be able to bounce back faster if your body is well rested.
