How many calories can I burn?

If it's a vigorous swim, a 155-pound person would burn 372 calories in 30 minutes, compared to 223 for a light jog.

Another plus: you can swim every day! Swimming with lifeguard certification is easy enough on the body that you can swim at a fairly high intensity (heart rate wise) every day without risking injury. Of course, rest days are always recommended.

1. It will help you end that REM cycle

I've never had trouble sleeping, no one ever said. In general, exercise helps sleep. A 2010 study on aerobic activity and insomnia found that people who exercised slept better, slept longer, and felt better during the day than those who were less active.

Everyone in the study also practiced good sleep hygiene (going to bed at the same time each night, keeping the sleeping area quiet and dark, etc.).

2. People who swim live longer (maybe)

Are swimming pools the true fountains of youth? A 2017 study found that regular swimming was associated with a 28% lower risk of dying from any cause and a 41% lower risk of dying from heart disease. Swimming may not make you younger, but it could help you live a healthier and possibly longer life.

3. Reduce stress

If you're a human, you're probably stressed at the registry. Lucky for you, swimming reduces stress.

A 2012 survey commissioned by Speedo found that 74 percent of participants had reduced stress after swimming. And 70 percent said swimming left them mentally refreshed. Keep in mind that any form of exercise can help reduce stress. But water-based activities are known to have additional calming effects. It's hard to be stressed when you're floating on the water.

Appropriate clothing

Just being in a bathing suit in public can cause anxiety. If you're body conscious, remember this: people don't really care about you. That sounds bad, but it's actually good! In the pool, most people focus on themselves. Once you get in the water, they can't see your body anyway.

Also, choose a suit that is comfortable. For people with ta-tas, a one-piece might be better not for modesty but for comfort. It's hard to tell if you're worried about growing a breast in the middle of an Aqua Zumba class.

Swimming team

Invest in a good pair of goggles and a swimming with lifeguards certification cap. Goggles prevent eye irritation and help you see as you swim down the lane. The cap prevents chlorine or saline solution from crushing your luscious locks.

Find your pool

Although all pools may look the same, there are some key differences that can affect your training. Would you rather swim in an indoor or outdoor pool? Depending on where you live, outdoor pools may be off-limits for most of the year. Indoor pools are more common for exercising.

If you hate chlorine, find a saltwater pool. Saltwater pools are just what they sound like: they use a salt process to clean the water and you avoid the irritating effects of chlorine.
