We all don't like the cold but a cold shower will help your health. I like to try new things and I have been taken cold showers and feeling stronger and better. If you are not weak then follow my example (at your own risk!).
1) Cognitive Function
Regeneration of synapses and nerve cells that may help cognitive function and prevent degenerative brain disease.
2) Weight loss
Produce healthier and more efficient brown adipose tissue that can lead to weigh loss.
Reduces inflammation by affecting cytokine production and vase-constriction of blood vessels.
Boosts immune system due to the production of lymphocytes that may help boost cognitive function and prevent brain disease.
Boost feel good hormones like dopamine and nor-epinephrine so may help in depression
6) Stress Response
Cold exposure creates a positive stress on the body giving many benefits through "hormeis."
7) Studies show
Cold water immersion at 14 Celsius for one hour increased metabolic rate by 350%, nor-epinephrine by 530% and dopamine by 250%.
I don't know about you, this may the fountain of youth that you need. You just need to get a tough mind then you will be well.
