It depends on whether you seek to combat insomnia or require concentration for an intellectual activity.
What kind of shower gives us more benefits? Those with hot water or the ones we drink with cold water? The answer to this question depends on what you want to achieve. Hot water, preferred by most users, has a relaxing effect and serves to relieve muscle aches and combat insomnia or even tension headaches. It does not cure a cold, nor the flu, but the steam that produces water at the temperature that many use, between 34 and 38 C, decongests the airways. In addition, so hot has a great cleaning power, but does not open the pores, as it is mistakenly attributed.
For its part, cold water clears the mind and body and, in that sense, helps concentration in any intellectual activity or that requires a lot of energy. This has a double physiological basis: on the one hand, the cold activates the circulation and provides more blood flow to the organs and tissues; And on the other hand, stimulates the production of noradrenaline, a hormone related to stress.
So? What is better? To shower with cold or hot water? Aristotle said that virtue is in the "fair middle" between two extreme attitudes; And dermatologists seem to agree with it, as it is what they recommend: warm water. Because with a very hot or cold temperature the skin becomes more dry. So it is best to place the thermostat at about 30 ° C.
