Cerner April Newsletter- Stages of Sleep

-

Sleep is incredibly complex and has an impact on virtually all systems of the body. Within a minute after falling asleep, notable changes start to affect both your brain and body. All of these changes that happen during sleep are connected with your physical, emotional, and mental health. You should get 7-9 hours of sleep each night to allow your body to properly cycle through the 4 stages of sleep:

Stage 1 (shallow sleep): Your muscles start to relax, and your breathing slows. It is easy to wake up during this stage of sleep, and it lasts 1-5 minutes.

Stage 2 (light sleep): Your breathing and heart rate continue to slow down. You spend the most time in stage 2 sleep throughout the night. This stage of sleep lasts 10-60 minutes.

Stage 3 (deep sleep): Deep sleep is required to feel rested. You spend more time in stage 3 earlier in the night. This stage of sleep lasts 20-40 minutes.

Stage 4 (Rapid Eye Movement/REM sleep): This stage is associated with heightened brain activity, quick eye movements under the eyelids, and an increased heart rate. This stage of sleep is where vivid dreams occur. It is common to briefly awaken several times throughout the night, but it shouldn’t impact how rested you feel in the morning. If you find that you are waking too often during the night, try to develop healthy habits that can improve your sleep.

Establishing a stable sleep pattern can improve your sleep quality. Choose a specific time to wake up in the morning and a specific time to go to bed each night. If you get in bed and find yourself unable to sleep, then get out of bed. Extended time in bed can lead to tossing and turning. Lying in bed for long periods of time may also train yourself to remain awake in bed. Sleep happens naturally, and it is best to go to another room and return only when you are sleepy enough.

Another way you can improve your sleep quality is by only using the bedroom for sleep. Avoid watching TV, reading, or other activities that keep your mind awake. Do not plan activities, work, or solve problems while in bed. By engaging in activities that require alertness while in your bedroom, you are training yourself to stay awake. It’s best to make your bedroom a comfortable, dark, quiet place meant for only sleeping.

If you are struggling with sleep, talk to your healthcare provider. They will be able to assess your current health for underlying conditions or sleep disorders. They may also be able to talk to you about daily habits that can have an impact on your sleep.

The "Unhealthy" Fruit

-
Image
We all know that a healthy diet consists of plenty of fruits and vegetables. You may not be aware, however, that choosing just any "fruit" may not be the best way to meet your fruit quota for the day. Below is a list of foods that you may want to limit or avoid: Fruity, sweet cereals. Fruity, colorful cereals that leave your milk pink, orange or blue are definitely void of nutrition. But what about the cereals that contain dried fruit? Sure, they may taste good, but most are also filled with added sugars and unneeded calories - even if they supposedly have real fruit flavors. Begin weaning yourself from the "fruity" cereals by chopping some real, fresh fruit into a bowl of healthy, non sugar-containing, cereal. Fruity Desserts. Strawberry ice cream. Raspberry cheesecake. Cherry Pie. Yum! We know they have fruit in the name, but it doesn't mean they're healthy for us. Opt for healthy fruit-based desserts such as fruit parfaits and fruit sorbet. If you mu...

Welcoa Well Balanced: How to Protect and Maintain Eye Health

When it comes to eye health many adults mistakenly believe that as long as nothing is bothering their eyes, there’s no need to get them checked out. However, getting regular eye exams is very important, even if you think your vision is fine. Eye exams allow an eye care professional to monitor your eyes for common vision problems and signs of disease. There aren’t early warning signs for the most common eye diseases, so by identifying diseases early, you have the best treatment options and the best chance of preserving good vision. If you haven’t had an eye exam in more than a year or at all, schedule one now. A comprehensive exam will often include eye dilation. After checking your vision sharpness, your doctor will place drops in your eyes to dilate (widen) the dark center of your eyes, called the pupil. This allows more light into your eyes, just like opening a door lets light into a dark room. The doctor can then examine the inside of your eyes. Your eye doctor will tal...

To balance out the dark, cold, windy, and dry qualities of winter, here are some tips to keep your body, mind, and spirit thriving: Move every day in a way that you enjoy; walk outside and get some winter sun, try yoga at home, swim at the local indoor pool, cycle, etc. Cook seasonal vegetables, make soups and stews, eat a warm breakfast like oats, and incorporate healthy oils like olive oil or ghee into your meals. Keep warm colors around you to combat the winter "blues". Orange, gold, deep reds, encourage a cozy feeling. Cover up with a hat and scarf not only keeps you warm but also provides a sense of safety and calm when it's cold and windy. Head to bed a little earlier and/or wake up a little later when the sun is rising if possible. Get extra rest and sleep as the environment is darker. Go within and practice meditation. Winter can be a good time to reflect on yourself. Try something new! Get creative and pick up a new hobby, book, puzzle, something that excites you...
