Can I take a shower or swim while fasting?

Detailed answer

Yes. Taking a shower or a bath while fasting is allowed and does not affect your fast, even if you do it just to cool down. Swimming is also allowed, but you need to be more careful, because there is a higher chance of water getting into your mouth or nose and down your throat.

What the Sunnah says

A Companion reported seeing the Prophet, peace be upon him, pouring water over his head while fasting, because of thirst or the heat (Abu Dawud). The Companion Ibn Umar is also reported to have wet a cloth and put it on his body while fasting. Water touching or soaking into the skin is not eating or drinking, so it does not break the fast.

Showering in practice

• A cool shower is a good way to manage heat and tiredness in the afternoon.
• When washing your face, do not let water run into your mouth, and do not sniff water deep into your nose.
• If you need ghusl during the day, the same care applies; see fasting when you need ghusl.

Swimming in practice

• Keep your head above water when you can, and avoid diving or long underwater swims.
• Breathe out through your nose when your face is in the water, or use a nose clip.
• Do not swim so hard that you become exhausted or dehydrated during the fasting hours.

Some scholars consider swimming and diving disliked while fasting because of the risk of swallowing water. If water goes down your throat by accident, some scholars hold that the fast is still valid because it was unintended, while others advise making up the day; if you are unsure, ask a trusted local scholar. Swallowing water on purpose clearly breaks the fast. See also water in the throat during wudu.

Tips for hot days

Plan swims for after iftar if you can, when you are free to drink afterwards. During the day, stay in the shade, rest and cool your skin with water. Drinking enough between iftar and suhoor is the best protection; read how to avoid dehydration in Ramadan.
