You need to lose both body fat and water weight so you have to maintain a healthy diet as well. Too much sweat can drop your salt levels, which will lead to dizziness. Stay in the sauna for 30 minutes to get enough benefits of a light workout without also getting dehydrated.
Light workouts can be done by walking, playing tennis or just goofing off with friends, but long workouts are not short on their side effects of dehydration if you don’t keep tabs on your hydration levels. Dehydration has its own side effects like decreased attention span, difficulty concentrating and reduced cognitive function ability—acute dehydration (a loss of one-fifth of total body fluids) may result in death from organ failure over the course of about five days.
The National Institutes of Health’s MedlinePlus website says, “Being well-hydrated is important for almost every function in your body.” So the only way to avoid this effect is by drinking lots of water and electrolytes—the minerals sodium (Na+) and potassium (K+). Your body will lose these minerals when you sweat, and the best way to replenish them is by drinking enough water.
You need to listen for your body as well since different people tend to lose electrolytes differently. So if you’re feeling dizzy or lightheaded, head to a cool place and have some salty snacks like crackers with cheese or nuts. Stay away from carbonated drinks like soda because they have too much sugar and caffeine.
If you feel bad after every time you exercise, it’s possible that these minerals are not the problem—maybe your blood sugar levels are low or maybe there is something else wrong with you. But if this happens after every workout or even sometimes during a workout, then you’re probably just dehydrated.
Going into the sauna in Riga will also help get rid of water weight, which is good if your goal is to lose fat and build muscle for summer. The easiest way to tell if you’ve lost enough body fat for a swimsuit? If a guy can see your nipples through it and a girl’s butt doesn’t look like two water balloons stuffed into a sack.
It’s hard to do, but try holding back on the sweating and drinking until you just can’t anymore, and then use that “emergency” time as your workout time. But afterward, you must get rehydrated in order to prevent dizziness.
