Stress is known to lower the levels of Libido in both men and women. Stress is meant to keep us alert and focus on the threat at hand. As humans we can't be focused on the threat and sex at the same time as a result a short-term stress response may become long term because of worries, concerns, and long-term feelings of generalized stress which can switch off libido.
Natural Libido therapy using ProBLEN supplements can lower mood swings, stress, and raise Libido. Along with natural supplements other suggestions to aid in raising your Libido are Exercise, this will increase your energy levels, make you feel more attractive, and help relax you in the hours after exercise. Regular rest and relaxation. Do things you enjoy, socialize, partake in hobbies, and take some time in lying down. Eat regularly. Missing a meal too often increases stress hormones within our bodies because we are now in famine mode and need the stress energy to hunt.
That means less available energy for sex. Don't overwork. Unless you have significant work-free periods and a proper wind downtime after work, your mind and body will still be in work mode.
