Don’t let the half-hour rule stop you from swimming right after a meal.
You can catch a cold from air conditioning
This particularly popular myth has been going around for ages but yes it is a myth. While the air conditioning will not make you catch a cold, extreme changes in temperature can weaken your immune system and if those around you have a cold, you could be more susceptible. So while cold air alone won’t make you sick, jumping from the sweltering heat to the icy cool freshness of your air conditioned home, can make you more susceptible to catching a virus.
The best thing to do is avoid extreme heat whenever possible and keep your air conditioning at a refreshing but moderate level. This will prevent your body from feeling excessive fluctuations and allow for more gradual body temperature changes.
Any drink will rehydrate you on a hot day
While a soft drink or ice-cold beer may really feel like they’re hitting the spot, they aren’t doing the job you need them to do. In fact, it’s a myth that any drink will rehydrate you. Drinks high in sugar or alcoholic beverages will actually further dehydrate you. If you’re engaging in physical activity in the heat you’ll need even more water to keep from dehydrating , so always bring plenty along with you.
You can’t get a sunburn on a cloudy day
This is one myth that, if believed, can have harsh consequences. Even the thickest of clouds do not have the ability to block out UV rays. The sun may be hidden away, but it’s still there and although the breeze may keep you feeling fresh and cool, you are still at risk for sunburn. In fact, some of the worst sunburns occur on cloudy days, when people feel cool enough to stay out all day long. The best way to protect your skin is to wear adequate sun protection and minimize your time outdoors between peak hours of the day. If you absolutely have to be out all day, be sure to take breaks and find shelter every 20 to 30 minutes.
Butter soothes sunburn
Putting butter on a sunburn is certainly not going to soothe the pain. In fact, it may even make the pain worse or delay the healing process. There are also concerns that butter may contain bacteria and could cause an infection. Instead, apply aloe vera gel. If you feel that isn’t enough, ask your pharmacist or visit your doctor to find out about other options that might be right for you
A swim in the pool can replace a shower
Unfortunately, this is a myth. This is especially important to keep in mind when using public pools, where swimmers often do not shower before entering the water. Public pools have a high level of chlorine but there is still plenty of bacteria, so be sure to wash off once you’re done swimming . If you’re using a private pool or a salt-water pool, it is still not a good substitute for a shower.
Swimming on a full stomach will make you ill
No, swimming on a full stomach will not make you sick but it can give you cramps. While cramps are not the end of the world, they can be uncomfortable. This is because your stomach is full and not finished digesting. But, if you can swim laps in a pool right after a meal, go right ahead. Don’t let the half-hour rule stop you anymore. Of course, if your meal included alcohol, you shouldn’t go swimming.
