Is Your Immune System Ready for Winter?

You’re ready to face the elements with your winter wardrobe, but what about your immune system – what’s your first line of immune defense against the winter weather?

The strength of your immune system is influenced by many factors, chief of which is your lifestyle. Lack of restful sleep, a poor diet, too little physical activity, and prolonged stress make your body more vulnerable to illness. With the holiday season fast approaching, it’s important for you to build up your immune system now.
Here are a few steps you can take to beat the cold and flu season:

Eat well for optimal immune function

Whole foods – as opposed to processed foods – promote optimal immune function. Natural sources of zinc, vitamin D, and vitamin C, and vitamin A will provide your immune system with the antioxidants and micronutrients it needs to stay strong. Zinc and vitamin C help reduce the length and severity of col
Here are a few foods to add to your diet this winter:

  • Zinc: Helps reduce the length and severity of colds
  • Foods rich in zinc: Grass-fed beef, nuts like cashews, pumpkin seeds, organic chicken, chickpeas, mushrooms, spinach, lentils, and hemp seeds and more.
  • Vitamin A helps prevent respiratory infections
  • Foods rich in Vitamin A: butternut squash, broccoli, butter, carrots, egg yolks, grass-fed beef, kale, wild-caught salmon, spinach, sweet potatoes and more.
  • Vitamin C: Helps reduce the length and severity of colds
  • Foods rich in Vitamin C: Broccoli, Brussels sprouts, cauliflower, grapefruit, guava, kiwi, mangoes, oranges, papaya, parsley, red & green peppers, and more.
  • Vitamin D helps prevent respiratory infections
  • Foods rich in Vitamin D: Winter months make it harder to get the best source of vitamin D – sunlight. You can get also get it from cod liver oil, wild-caught salmon, mackerel, sardines, eggs. Vitamin D plays a major role in keeping you healthy. That’s why it’s important to check vitamin D levels so you can avoid a vitamin D deficiency. Be sure to ask your healthcare practitioner to check your vitamin D levels or contact us to learn how you can prevent vitamin D deficiency.

Stay Hydrated

The mucus membranes inside your nose and airways are part of your immune system’s front line of defense. These membranes need moisture to function effectively. Drinking plenty of fluids – especially warm beverages – helps keep this first line of defense intact.

Keep Moving

Physical activity on a regular basis increases your immune system’s ability to fight off illness. Exercise is often one of the first things we drop when life gets hectic, but it truly is a magic pill for your body, mind, and soul with regard to its benefits. If you feel you are coming down with a cold, then make sure you go easy and give your body a chance to rest.

Sleep deep

You don’t need anyone to tell you how important sleep is to your overall health – you know how you feel after missing just one night of good sleep. Too little sleep and poor sleep are both linked with inflammation – a major contributor to poor physical and mental health. Sleep also plays a vital role in the ability of your immune system to effectively respond to infection.

The quality of your sleep is just as important as the quantity of your sleep. The good news is that there are many things you can do to improve your sleep. Here are a few tips for better sleep:

  • Aim for 8 hours daily
  • Go to bed & get up at the same time each day
  • Keep your bedroom quiet, cool, and dark
  • Get your daily dose of physical activity – especially outdoor physical activity
  • Watch what you eat and drink and when you eat and drink: Avoid eating a large meal within a few hours of going to bed; avoid drinking caffeinated beverages late in the day, and limit alcoholic beverages which can disrupt your sleep.
  • Consider deep breathing exercises or guided meditation to help you fall asleep or write down your worries/make a to do list so you can let your mind rest during the night and be ready the next day to find solutions & begin to check off your to do list.

Recently, scientific research has found evidence that a healthy diet and healthy digestion contribute to good sleep. If you have digestive difficulties or struggle to get a good night’s sleep, please contact us for help.

Reduce stress

Easier said then done, but you can still take small steps today to reduce your stress:

  • Push back from your desk and take a few slow deep breaths right now
  • Go for a short walk outside or just around your building
  • Connect with friends and family
  • Schedule a massage
  • Take a yoga class
  • Laugh
