2. Reduction of stress, depression, and anxiety
Cold showers operate by causing significant shock and stress on your body. If you take them regularly, you will begin a process known as hardening. During this period, your nervous system becomes accustomed to being “struck” with modest quantities of physical stress, preparing you for when truly stressful situations arise. Consequently, your body and mind are designed to deal with any problematic scenario that occurs.
Also, cold water causes endorphins to be released into our system, making us more alert, energetic, and joyful. A research investigation found that persons suffering from depression felt better after having up to 5-minute cold showers 2-3 times per week.
