Cold or hot shower? Here are the benefits of each

Choosing the temperature of your shower water is a decision that divides opinion. Some people can’t stand a cold shower, whilst others wouldn’t give up hot water even in summer. But is one better than the other?

The truth is that science has shown that both options have benefits for our health and wellbeing, as well as some drawbacks to bear in mind. Ultimately, whether you choose a cold or hot shower depends on when you take it and what benefits you’re looking for.

Why do we tend to prefer hot showers?

Hot showers are favoured by many because of the sense of comfort they provide. When our body comes into contact with heat, our blood vessels dilate and our muscles relax, which improves circulation and relieves tension and stiffness. For this reason, after a hot shower we feel more relaxed and tend to sleep better.

Beyond their relaxing effects, they can also help alleviate the symptoms of flu and colds. The steam opens up the airways and provides temporary relief from a blocked nose.

New findings on cold showers

Although not as pleasant or relaxing as hot water, cold water can also have many benefits for our wellbeing. This type of shower provides an invigorating sensation, as it stimulates the release of noradrenaline and adrenaline. These two neurotransmitters influence our mood, reduce inflammation in the body, help clear the mind and improve concentration.

The evidence regarding all the benefits of cold showers remains limited, but some studies have already suggested that they could strengthen our immune system and aid recovery from respiratory viruses.

Some drawbacks to bear in mind

Although they are very soothing, excessively hot showers also have their downsides. This is particularly true for our skin’s protective barrier, as they increase dryness and irritation of the skin. Furthermore, it is worth bearing in mind that intense heat can also cause a drop in blood pressure, a feeling of weakness and even dizziness. For these reasons, it is advisable to avoid showering at temperatures above 38 degrees and to limit the duration of the shower.

As for cold showers, experts advise against them when we are ill or have a cold, as they can interfere with the body’s recovery process. They are also not recommended for people who are hypersensitive to the cold or who have cardiovascular conditions. Furthermore, they warn that lowering the temperature below 10 degrees or taking these showers for too long can lead to skin irritation and damage.

Key considerations when choosing between a cold or hot shower

Most of the benefits offered by both options depend on when we choose them. To promote a good night’s sleep or reduce stress, for example, it is advisable to opt for short, hot showers. On the other hand, if we want to energise ourselves, maintain our energy levels or aid muscle recovery after exercise, a cold shower may be more suitable.

There are also contrast showers, which involve alternating between periods of cold and hot water. These temperature changes help to stimulate circulation and can aid muscle recovery. Furthermore, they promote vasoconstriction and vasodilation of the blood vessels, a process that helps to boost blood flow.

However, beyond choosing between a cold or hot shower, experts agree that the best option for everyday use is a mild and comfortable temperature.
