This lifestyle change saves money, improves your health and cuts emissions. But there’s a catch

Key Points:

• Taking cold showers is a simple, cost-free lifestyle change that can reduce carbon emissions, save money on utility bills, and improve physical and mental health, despite initial discomfort.
• A study by psychologist Dr. Lena Glaser involving 719 participants showed that while some quit early due to discomfort, most adapted over time and reported feeling more awake, refreshed, and healthier.
• Participants who consistently took cold showers experienced a 31% reduction in sick days and cut their CO2 emissions by 15 kilograms per person over 12 weeks, comparable to driving 100 kilometers less.
• Cold showers reduce water and energy use by discouraging long showers and lowering water heating needs, making them an effective way to save energy and reduce household emissions.
• Dr. Glaser recommends gradually lowering water temperature and listening to one’s body, emphasizing that even small reductions in shower temperature can have positive environmental and health impacts.
