Anxiety is not to be taken lightly. Of course, if the problem is severe or persistent, medical attention and/or proper counselling is vital. However, there are some small daily lifestyle changes we can make to relieve milder cases or just give our mental health a boost. One of these changes, according to a recent study, is all to do with the temperature of your shower. According to Lifehack, a cold shower can do wonders for your mental health, boosting your mood and activating beta-endorphin and nor-adrenaline (used in anti-depressant medications) in the brain. Although this "hydrotherapy" is not yet recognised in mainstream medicine, many studies show that those who swim in cold water and take cold showers reported improved mood, less stress, more energy and pain relief from rheumatism. According Dr. Nikolai Shevchuk, we need to be exposed to more thermal stress and a cold shower is a great way of getting this naturally without any nasty side effects. It might not be nice first thing in the morning but if you're having your normal warm shower, maybe even try blasting it to cold for a few seconds before you get out.
