Off course you can always blame it on your hormones or you can actually take responsability for it and try to do something about it....
In this article I'll give you three poses you can do that will change your mood instantly. Certain yoga poses stimulate your glands, causing your brain to release chemicals that change your mood. You do need to hold the pose for at least 5 breaths (this is about 30 seconds) to have any stimulating effect on the glands.
1. Camel Pose
This pose is very effective when you're feeling down or depressed.
Get on your knees with your feet hip width apart. Place your hands in your lower back and start pushing your hips forward. Let your head fall back, and catch your ankles.
To get out of the pose, first place your hands back on the lower back, put your chin on your chest, and slowly roll down and take a rest in Child's Pose.
2. Cat and Cow Pose
This personally is one of my favourite poses and I put in every practice I do, even if I only have 10 minutes.
This pose will help you sleep better. Better sleep automatically results in a better mood!
Get on knees and hands and make sure your knees are hip width and the hands are 90 degrees under your shoulders. Take a breath in through your nose and look at the ceiling while pushing your tailbone towards the ceiling.
While you take a long breath out trough the mouth, round the spine pushing your belly button towards the ceiling. Repeat 4 to 5 times.
3. Downward Facing Dog
Feeling bored? This pose will immediately wake you up. Because of the inversion (your heart is lower than your knees in this pose), fresh blood with nutrients and oxygen is send to the brain, waking you up.
Start on hand and knees like the Cat and Cow pose from above and curl the toes. On an outbreath, push your hips towards the ceiling. Push your heals and shoulders towards the mat, release your head down, and push the tailbone up.
Stay for at least 5 breaths and you can bend one leg and then the other to release tension in your calves.
These are just 3 poses that just take 3 minutes of your time. If you want to do all three of them, I suggest you start with Cat and Cow then go to Down Dog. Release tension in the back with Camel pose and rest in Child's pose.
