Stress is a natural reaction that our body experiences when there are stimuli of any sort. But too much stress can be detrimental.

Emotional stress, especially, lingers for months and can cause long term effects to our immune system.

Accumulated stresses caused by the struggles of everyday life, when unmanaged can cause high blood pressure, fatigue, depression, anxiety, and a laundry list of heart disease.

We've been through an, especially stressful year. And the holiday season is expected to add more layers to that.

Don't allow stress to steal your joy this holiday season. Here are 12 Rules that can make Christmas a really special time.

1.    Decline Invitations. An evening with nosy relatives. Mini-reunions with schoolmates. Unsafe office parties. Don't feel that you must accept all these invitations. Choose the ones that will mean the most to you.

2.    It's a meal, not a contest. Every meal does not have to be Instagram worthy. Dinner doesn't have to be a 12-course meal. You can order for lunch and have store-bought dessert, too. Perfection isn't the goal here, it's to be blissfully full with family.

3.    Set aside 30 minutes of "Me" time. If you are quarantining and spending the holidays with family, days can feel like a blur. It's one meal after another and it can get chaotic. Commit to doing at least 30 minutes for yourself. This can be a quick exercise, some stretches, or a walk around the corner.

4.    Follow your daily routine. If you have a healthy daily routine, do not bulldoze it this season. If you've established daily rituals like reading before bedtime or meditating in the morning, do not forego them now. You need to anchor yourself through soothing and calming self-care activities.

5.    Get proper sleep. As with your daily routine, sleep is essential. For you to entertain the family and manage the day's activities, you need to get enough shuteye. Don't be cranky and irate. You'll children will think you're the Grinch! Be present for everyone. Sleep well.

6.    Stick to your Greatest Hits. It's tempting to experiment with new recipes but honestly, now is not the time for that. You might try something new only to discover it will take at least 12 hours of prep time (causing hungry kids)! Make your meals a concert for your greatest hits. This will add more fun to your family tradition.

7.    Remember what Christmas is all about. It may mean different things to different families, but essentially, it should be about love. Let family and friends know how much you mean to them today.

8.    Be grateful. Stress can also be caused by a mindset that's focused on the negative. Set your heart and mind on being grateful. Remind yourself and the obnoxious complainers in your household how doubly blessed you are. All things considered.
